Caution

To ensure proper airflow it is necessary to rack the servers using rail kits. Physically placing the units on top of one another or “stacking” without the use of the rail kits blocks the air vents on top of the servers, which could result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount your servers on rail kits when you are installing them into the rack because these rails provide the minimal spacing required between the servers. No additional spacing between the servers is required when you mount the units using rail kits.

Caution

Avoid uninterruptible power supply (UPS) types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco UCS, which can have substantial current draw fluctuations from fluctuating data traffic patterns.

When you are installing a server, use the following guidelines:

- Plan your site configuration and prepare the site before installing the server.

- Ensure that there is adequate space around the server to allow for accessing the server and for adequate airflow. The airflow in this server is from front to back.

- Ensure that the air-conditioning meets the thermal requirements listed in the Environmental Specifications.

- Ensure that the cabinet or rack meets the requirements listed in the Rack Requirements.

- Ensure that the site power meets the power requirements listed in the Power Specifications. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Rack Requirements

The rack must be of the following type:

- A standard 19-in. (48.3-cm) wide, four-post EIA rack, with mounting posts that conform to English universal hole spacing, per section 1 of ANSI/EIA-310-D-1992.

- The rack-post holes can be square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), #12-24 UNC, or #10-32 UNC when you use the Cisco-supplied slide rails.

- The minimum vertical rack space per server must be one rack unit (RU), equal to 1.75 in. (44.45 mm).

Required Equipment For Service Procedures

The following tools and equipment are used to perform the procedures in this chapter:

- T-30 Torx driver (supplied with replacement CPUs for heatsink removal)

- #1 flat-head screwdriver (supplied with replacement CPUs for heatsink removal)

- #1 Phillips-head screwdriver (for M.2 SSD and intrusion switch replacement)

- Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat

Shutting Down and Removing Power From the Server

The server can run in either of two power modes:

- Main power mode—Power is supplied to all server components and any operating system on your drives can run.

- Standby power mode—Power is supplied only to the service processor and certain components. It is safe for the operating system and data to remove power cords from the server in this mode.

Caution

After a server is shut down to standby power, electric current is still present in the server. To completely remove power as directed in some service procedures, you must disconnect all power cords from all power supplies in the server.

You can shut down the server by using the front-panel power button or the software management interfaces.

- Shutting Down Using the Power Button

- Shutting Down Using The Cisco IMC GUI

- Shutting Down Using The Cisco IMC CLI

Shutting Down Using the Power Button

Procedure

Step 1

Check the color of the Power button/LED:

- Amber—The server is already in standby mode and you can safely remove power.

- Green—The server is in main power mode and must be shut down before you can safely remove power.

Step 2

Invoke either a graceful shutdown or a hard shutdown:

Caution

To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the operating system.

- Graceful shutdown—Press and release the Power button. The operating system performs a graceful shutdown and the server goes to standby mode, which is indicated by an amber Power button/LED.

- Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately enter standby mode.

Hot Swap vs Hot Plug

Some components can be removed and replaced without shutting down and removing power from the server. This type of replacement has two varieties: hot-swap and hot-plug.

- Hot-swap replacement—You do not have to shut down the component in the software or operating system. This applies to the following components:

- SAS/SATA hard drives

- SAS/SATA solid state drives

- Cooling fan modules

- Power supplies (when redundant as 1+1)

- Hot-plug replacement—You must take the component offline before removing it for the following component:

- NVMe PCIe solid state drives

Removing and Replacing Components

Warning

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Statement 1029

Caution

When handling server components, handle them only by carrier edges and use an electrostatic discharge (ESD) wrist-strap or other grounding device to avoid damage.

Tip

You can press the unit identification button on the front panel or rear panel to turn on a flashing, blue unit identification LED on both the front and rear panels of the server. This button allows you to locate the specific server that you are servicing when you go to the opposite side of the rack. You can also activate these LEDs remotely by using the Cisco IMC interface.

Note

You do not have to shut down the server or drive to replace SAS/SATA hard drives or SSDs because they are hot-swappable. To replace an NVMe PCIe SSD drive, which must be shut down before removal, see Replacing a Front-Loading NVMe SSD.

- SAS/SATA Drive Population Guidelines

- 4K Sector Format SAS/SATA Drives Considerations

- Replacing a SAS/SATA Drive

SAS/SATA Drive Population Guidelines

The server is orderable in the following different version

- SE-CL-L3 —Small form-factor (SFF) drives, with 10-drive backplane. Supports up to 10 2.5-inch SAS/SATA drives. Drive bays 1 and 2 support NVMe SSDs.

Drive bay numbering is shown in the following figures.

Small Form-Factor Drive Versions, Drive Bay Numbering

Large Form-Factor Drive Version, Drive Bay Numbering

Observe these drive population guidelines for optimum performance:

- When populating drives, add drives to the lowest-numbered bays first.

- Keep an empty drive blanking tray in any unused bays to ensure proper airflow.

- You can mix SAS/SATA hard drives and SAS/SATA SSDs in the same server. However, you cannot configure a logical volume (virtual drive) that contains a mix of hard drives and SSDs. That is, when you create a logical volume, it must contain all SAS/SATA hard drives or all SAS/SATA SSDs.

4K Sector Format SAS/SATA Drives Considerations

About this task

- You must boot 4K sector format drives in UEFI mode, not legacy mode. UEFI mode is the system default. Only if the mode has been changed and must be changed back to UEFI mode, see the following procedure.

- Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID volume.

- Operating system support on 4K sector drives is as follows: Windows: Win2012 and Win2012R2; Linux: RHEL 6.5, 6.6, 6.7, 7.0, 7.2; SLES 11 SP3, and SLES 12. ESXi/Vmware is not supported.

Replacing a Front-Loading NVMe SSD

This section is for replacing 2.5-inch or 3.5-inch form-factor NVMe solid-state drives (SSDs) in front-panel drive bays.

- Front-Loading NVMe SSD Population Guidelines

- Front-Loading NVME SSD Requirements and Restrictions

- Enabling Hot-Plug Support in the System BIOS

- Replacing a Front-Loading NVMe SSD

- Installing a PCIe Cable For Front-Loading NVMe SSDs

Front-Loading NVMe SSD Population Guidelines

The front drive bay support for 2.5-inch NVMe SSDs:

- SE-CL-L3 —Small form-factor (SFF) drives, with 10-drive backplane. Drive bays 1 and 2 support 2.5-inch NVMe SSDs.

Front-Loading NVME SSD Requirements and Restrictions

Observe these requirements:

- The server must have two CPUs. PCIe riser 2 is not available in a single-CPU system. PCIe riser 2 has connectors for the cable that connects to the front-panel drive backplane.

- PCIe cable CBL-NVME-C220FF. This is the cable that carries the PCIe signal from the front-panel drive backplane to PCIe riser 2. This cable is for all versions of this server.

- Hot-plug support must be enabled in the system BIOS. If you ordered the system with NVMe drives, hot-plug support is enabled at the factory.

Observe these restrictions:

- NVMe SFF 2.5- and 3.5-inch SSDs support booting only in UEFI mode. Legacy boot is not supported. For instructions on setting up UEFI boot, see 4K Sector Format SAS/SATA Drives Considerations.

- You cannot control NVMe PCIe SSDs with a SAS RAID controller because NVMe SSDs interface with the server via the PCIe bus.

- UEFI boot is supported in all supported operating systems. Hot-insertion and hot-removal are supported in all supported operating systems except VMWare ESXi.

Enabling Hot-Plug Support in the System BIOS

Hot-plug (OS-informed hot-insertion and hot-removal) is disabled in the system BIOS by default.

- If the system was ordered with NVMe PCIe SSDs, the setting was enabled at the factory. No action is required.

- If you are adding NVMe PCIe SSDs after-factory, you must enable hot-plug support in the BIOS. See the following procedures.

Enabling Hot-Plug Support Using the BIOS Setup Utility

Installing a PCIe Cable For Front-Loading NVMe SSDs

The front-loading NVMe SSDs interface with the server via the PCIe bus. Cable CBL-NVME-C220FF connects the front-panel drive backplane to the PCIe riser 2 board on the PCIe riser assembly.

- If the server was ordered with 2.5- or 3.5-inch form-factor NVMe SSDs, this cable was preinstalled at the factory. No action is required.

- If you are adding 2.5- or 3.5-inch form-factor NVMe SSDs for the first time, you must order and install the cable as described in the following procedure.

Procedure

Step 1

Connect the two connectors on one end of the cable to the PCIE-A1 and PCIE-A2 connectors on the drive backplane.

Step 2

Route the cables through the chassis cable guides to the rear of the server as shown below.

Step 3

Connect the single connector on the other end of the cable to the PCIE-FRONT connector on PCIe riser 2.

PCIe Cabling to Drive Backplane

Replacing Fan Modules

The seven fan modules in the server are numbered as shown in the figure 1.

Tip

Each fan module has a fault LED next to the fan connector on the motherboard. This LED lights green when the fan is correctly seated and is operating OK. The LED lights amber when the fan has a fault or is not correctly seated.

Caution

You do not have to shut down or remove power from the server to replace fan modules because they are hot- swappable. However, to maintain proper cooling, do not operate the server for more than one minute with any fan module removed.

Procedure

Step 1

Remove an existing fan module:

1. Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution

If you cannot safely view and access the component, remove the server from the rack.

2. Remove the top cover from the server as described in Removing the Server Top Cover.

3. Grasp the fan module at its front and rear finger-grips. Lift straight up to disengage its connector from the motherboard.

Step 2

Install a new fan module:

1. Set the new fan module in place. The arrow printed on the top of the fan module should point toward the rear of the server.

2. Press down gently on the fan module to fully engage it with the connector on the motherboard.

3. Replace the top cover to the server.

4. Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button.

Replacing CPUs and Heatsinks

This section contains CPU configuration rules and the procedure for replacing CPUs and heatsinks:

- CPU Configuration Rules

- Tools Required For CPU Replacement

- Replacing a CPU and Heatsink

- Moving an M5 Generation CPU

CPU Configuration Rules

This server has two CPU sockets on the motherboard. Each CPU supports six DIM channels (12 DIMM slots). See DIMM Population Rules and Memory Performance Guidelines.

- The server operates with two identical CPUs installed.

- The maximum combined memory allowed in the 12 DIMM slots controlled by any one CPU is 768 GB. To populate the 12 DIMM slots with more than 768 GB of combined memory, you must use a high-memory CPU that has a PID that ends with an "M", for example, UCS-CPU-6134M.

Tools Required For CPU Replacement

You need the following tools and equipment for this procedure:

- T-30 Torx driver—Supplied with replacement CPU.

- #1 flat-head screwdriver—Supplied with replacement CPU.

- CPU assembly tool—Supplied with replacement CPU. Orderable separately as Cisco PID UCS-CPUAT=.

- Heatsink cleaning kit—Supplied with replacement CPU. Orderable separately as Cisco PID UCSX-HSCK=.

One cleaning kit can clean up to four CPUs.

- Thermal interface material (TIM)—Syringe supplied with replacement CPU. Use only if you are reusing your existing heatsink (new heatsinks have a pre-applied pad of TIM). Orderable separately as Cisco PID UCS-CPU-TIM=.

One TIM kit covers one CPU.

Replacing a CPU and Heatsink

Caution

CPUs and their sockets are fragile and must be handled with extreme care to avoid damaging pins. The CPUs must be installed with heatsinks and thermal interface material to ensure cooling. Failure to install a CPU correctly might result in damage to the server.

Procedure

Step 1

Remove the existing CPU/heatsink assembly from the server:

1. Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server.

2. Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution

If you cannot safely view and access the component, remove the server from the rack.

3. Remove the top cover from the server as described in Removing the Server Top Cover.

4. Use the T-30 Torx driver that is supplied with the replacement CPU to loosen the four captive nuts that secure the assembly to the motherboard standoffs.

Note

Alternate loosening the heatsink nuts evenly so that the heatsink remains level as it is raised. Loosen the heatsink nuts in the order shown on the heatsink label: 4, 3, 2, 1.

5. Lift straight up on the CPU/heatsink assembly and set it heatsink-down on an antistatic surface.

2. Pinch inward on the CPU-carrier inner-latch that is nearest the TIM breaker slot and then push up to disengage the clip from its slot in the heatsink corner.

3. Insert the blade of a #1 flat-head screwdriver into the slot marked TIM BREAKER.

Caution

In the following step, do not pry on the CPU surface. Use gentle rotation to lift on the plastic surface of the CPU carrier at the TIM breaker slot. Use caution to avoid damaging the heatsink surface.

4. Gently rotate the screwdriver to lift up on the CPU until the TIM on the heatsink separates from the CPU.

Note

Do not allow the screwdriver tip to touch or damage the green CPU substrate.

5. Pinch the CPU-carrier inner-latch at the corner opposite the TIM breaker and push up to disengage the clip from its slot in the heatsink corner.

6. On the remaining two corners of the CPU carrier, gently pry outward on the outer-latches and then lift the CPU-assembly from the heatsink.

Note

Handle the CPU-assembly by the plastic carrier only. Do not touch the CPU surface. Do not separate the CPU from the carrier.

Step 3

The new CPU assembly is shipped on a CPU assembly tool. Take the new CPU assembly and CPU assembly tool out of the carton.

If the CPU assembly and CPU assembly tool become separated, note the alignment features shown below for correct orientation. The pin 1 triangle on the CPU carrier must be aligned with the angled corner on the CPU assembly tool.

Caution

CPUs and their sockets are fragile and must be handled with extreme care to avoid damaging pins.

Step 4

Apply new TIM to the heatsink:

Note

The heatsink must have new TIM on the heatsink-to-CPU surface to ensure proper cooling and performance.

- If you are installing a new heatsink, it is shipped with a pre-applied pad of TIM. Go to step 5.

- If you are reusing a heatsink, you must remove the old TIM from the heatsink and then apply new TIM to the CPU surface from the supplied syringe. Continue with step a below.

1. Apply the cleaning solution that is included with the heatsink cleaning kit (UCSX-HSCK=) to the old TIM on the heatsink and let it soak for a least 15 seconds.

2. Wipe all of the TIM off the heatsink using the soft cloth that is included with the heatsink cleaning kit. Be careful to avoid scratching the heatsink surface.

3. Using the syringe of TIM provided with the new CPU (UCS-CPU-TIM=), apply 4 cubic centimeters of thermal interface material to the top of the CPU. Use the pattern shown below to ensure even coverage.

Thermal Interface Material Application Pattern

Caution

Use only the correct heatsink for your CPUs to ensure proper cooling. There are two different heatsinks: UCSC-HS-C220M5= for standard-performance CPUs 150 W and less; UCSC-HS2-C220M5= for high-performance CPUs above 150 W. Note the wattage described on the heatsink label.

Step 5

With the CPU assembly on the CPU assembly tool, set the heatsink onto the CPU assembly. Note the pin 1 alignment features for correct orientation. Push down gently until you hear the corner clips of the CPU carrier click onto the heatsink corners.

Caution

In the following step, use extreme care to avoid touching or damaging the CPU contacts or the CPU socket pins.

Step 6

Install the CPU/heatsink assembly to the server:

1. Lift the heatsink with attached CPU assembly from the CPU assembly tool.

2. Align the CPU with heatsink over the CPU socket on the motherboard, as shown below.

Note the alignment features. The pin 1 angled corner on the heatsink must align with the pin 1 angled corner on the CPU socket. The CPU-socket posts must align with the guide-holes in the assembly.

4. Use the T-30 Torx driver that is supplied with the replacement CPU to tighten the four captive nuts that secure the heatsink to the motherboard standoffs.

Caution

Alternate tightening the heatsink nuts evenly so that the heatsink remains level while it is lowered. Tighten the heatsink nuts in the order shown on the heatsink label: 1, 2, 3, 4. The captive nuts must be fully tightened so that the leaf springs on the CPU socket lie flat.

5. Replace the top cover to the server.

6. Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button.

Moving an M5 Generation CPU

Tool required for this procedure: T-30 Torx driver

Caution

When you receive a replacement server for an RMA, it includes dust covers on all CPU sockets. These covers protect the socket pins from damage during shipping. You must transfer these covers to the system that you are returning, as described in this procedure.

Procedure

Step 1

When moving an M5 CPU to a new server, you do not have to separate the heatsink from the CPU. Perform the following steps:

1. Use a T-30 Torx driver to loosen the four captive nuts that secure the assembly to the board standoffs.

Note

Alternate loosening the heatsink nuts evenly so that the heatsink remains level as it is raised. Loosen the heatsink nuts in the order shown on the heatsink label: 4, 3, 2, 1.

2. Lift straight up on the CPU/heatsink assembly to remove it from the board.

Note

Alternate tightening the heatsink nuts evenly so that the heatsink remains level while it is lowered. Tighten the heatsink nuts in the order shown on the heatsink label: 1, 2, 3, 4. The captive nuts must be fully tightened so that the leaf springs on the CPU socket lie flat.

Replacing Memory DIMMs

Caution

DIMMs and their sockets are fragile and must be handled with care to avoid damage during installation.

Caution

Cisco does not support third-party DIMMs. Using non-Cisco DIMMs in the server might result in system problems or damage to the motherboard.

Note

To ensure the best server performance, it is important that you are familiar with memory performance guidelines and population rules before you install or replace DIMMs.

- DIMM Population Rules and Memory Performance Guidelines

- Replacing DIMMs

DIMM Population Rules and Memory Performance Guidelines

This topic describes the rules and guidelines for maximum memory performance.

DIMM Slot Numbering

The following figure shows the numbering of the DIMM slots on the motherboard.

DIMM Slot Numbering

DIMM Population Rules

Observe the following guidelines when installing or replacing DIMMs for maximum performance:

- Each CPU supports six memory channels.

- CPU 1 supports channels A, B, C, D, E, F.

- CPU 2 supports channels G, H, J, K, L, M.

- Each channel has two DIMM sockets (for example, channel A = slots A1, A2).

- In a single-CPU configuration, populate the channels for CPU1 only (A, B, C, D, E, F).

- For optimal performance, populate DIMMs in the order shown in the following table, depending on the number of CPUs and the number of DIMMs per CPU. If your server has two CPUs, balance DIMMs evenly across the two CPUs as shown in the table.

Note

The table below lists recommended configurations. Using 5, 7, 9, 10, or 11 DIMMs per CPU is not recommended.

(G2, H2); (J2, K2); (L2, M2)

- The maximum combined memory allowed in the 12 DIMM slots controlled by any one CPU is 768 GB. To populate the 12 DIMM slots with more than 768 GB of combined memory, you must use a high-memory CPU that has a PID that ends with an "M", for example, UCS-CPU-6134M.

- Memory mirroring reduces the amount of memory available by 50 percent because only one of the two populated channels provides data. When memory mirroring is enabled, you must install DIMMs in even numbers of channels.

- The NVIDIA Tesla P-Series GPU can support more than 1 TB of memory in the server. All other NVIDIA GPUs (M-Series) can support only 1 TB or less of memory in the server.

- Observe the DIMM mixing rules shown in the following table.

DIMM Mixing Rules

DIMM Parameter

DIMMs in the Same Channel

DIMMs in the Same Bank

DIMM Capacity

For example, 8GB, 16GB, 32GB, 64GB, 128GB

You can mix different capacity DIMMs in the same channel (for example, A1, A2).

You cannot mix DIMM capacities in a bank (for example A1, B1). Pairs of DIMMs must be identical (same PID and revision).

DIMM speed

For example, 2666 GHz

You can mix speeds, but DIMMs will run at the speed of the slowest DIMMs/CPUs installed in the channel.

You cannot mix DIMM speeds in a bank (for example A1, B1). Pairs of DIMMs must be identical (same PID and revision).

DIMM type

RDIMMs or LRDIMMs

You cannot mix DIMM types in a channel.

You cannot mix DIMM types in a bank.

Memory Mirroring

The CPUs in the server support memory mirroring only when an even number of channels are populated with DIMMs. If one or three channels are populated with DIMMs, memory mirroring is automatically disabled.

Memory mirroring reduces the amount of memory available by 50 percent because only one of the two populated channels provides data. The second, duplicate channel provides redundancy.

Replacing DIMMs

Identifying a Faulty DIMM

Each DIMM socket has a corresponding DIMM fault LED, directly in front of the DIMM socket. See Internal Diagnostic LEDs for the locations of these LEDs. When the server is in standby power mode, these LEDs light amber to indicate a faulty DIMM.

Procedure

Step 1

Remove an existing DIMM:

1. Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server.

2. Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution

If you cannot safely view and access the component, remove the server from the rack.

3. Remove the top cover from the server as described in Removing the Server Top Cover.

4. Remove the air baffle that covers the front ends of the DIMM slots to provide clearance.

5. Locate the DIMM that you are removing, and then open the ejector levers at each end of its DIMM slot.

Step 2

Install a new DIMM:

Note

Before installing DIMMs, see the memory population rules for this server: DIMM Population Rules and Memory Performance Guidelines.

1. Align the new DIMM with the empty slot on the motherboard. Use the alignment feature in the DIMM slot to correctly orient the DIMM.

2. Push down evenly on the top corners of the DIMM until it is fully seated and the ejector levers on both ends lock into place.

3. Replace the top cover to the server.

4. Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button.

Replacing a Mini-Storage Module

The mini-storage module plugs into a motherboard socket to provide additional internal storage. The module is available in two different versions:

- SD card carrier—provides two SD card sockets.

- M.2 SSD Carrier—provides two M.2 form-factor SSD sockets.

Note

The Cisco IMC firmware does not include an out-of-band management interface for the M.2 drives installed in the M.2 version of this mini-storage module (UCS-MSTOR-M2). The M.2 drives are not listed in Cisco IMC inventory, nor can they be managed by Cisco IMC. This is expected behavior.

Replacing a SAS Storage Controller Card (RAID or HBA) in Riser 3

For hardware-based storage control, the server can use a Cisco modular SAS RAID controller or SAS HBA that plugs into a horizontal socket on a dedicated mRAID riser (internal riser 3).

Note

You cannot use a hardware RAID controller card and the embedded software RAID controller to control front-panel drives at the same time. See Embedded SATA RAID Controller for details.

- Storage Controller Card Firmware Compatibility

- Replacing a SAS Storage Controller Card (RAID or HBA)

Storage Controller Card Firmware Compatibility

Firmware on the storage controller (RAID or HBA) must be verified for compatibility with the current Cisco IMC and BIOS versions that are installed on the server. If not compatible, upgrade or downgrade the storage controller firmware using the Cisco Host Upgrade Utility (HUU) for your firmware release to bring it to a compatible level.

See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring server components to compatible levels: HUU Guides.

Note

For servers running in standalone mode only: After you replace controller hardware, you must run the Cisco Host Upgrade Utility (HUU) to update the controller firmware, even if the firmware Current Version is the same as the Update Version. This is necessary to program the controller's suboem-id to the correct value for the server SKU. If you do not do this, drive enumeration might not display correctly in the software. This issue does not affect servers controlled in UCSM mode.

Step 8

If your server is running in standalone mode, use the Cisco Host Upgrade Utility to update the controller firmware and program the correct suboem-id for the controller.

After you replace controller hardware (APIC-RAID-M5), you must run the Cisco Host Upgrade Utility (HUU) to update the controller firmware, even if the firmware Current Version is the same as the Update Version. This is necessary to program the controller's suboem-id to the correct value for the server SKU. If you do not do this, drive enumeration might not display correctly in the software. This issue does not affect servers controlled in UCSM mode.

Replacing a Boot-Optimized M.2 RAID Controller Module

The Cisco Boot-Optimized M.2 RAID Controller module connects to the mini-storage module socket on the motherboard. It includes slots for two SATA M.2 drives, plus an integrated 6-Gbps SATA RAID controller that can control the SATA M.2 drives in a RAID 1 array.

- Cisco Boot-Optimized M.2 RAID Controller Considerations

- Replacing a Cisco Boot-Optimized M.2 RAID Controller

Cisco Boot-Optimized M.2 RAID Controller Considerations

Review the following considerations:

- The minimum version of Cisco IMC that support this controller is 4.0(4) and later.

- This controller supports RAID 1 (single volume) and JBOD mode.

- A SATA M.2 drive in slot 1 (the top) is the first SATA device; a SATA M.2 drive in slot 2 (the underside) is the second SATA device.

- The name of the controller in the software is MSTOR-RAID.

- A drive in Slot 1 is mapped as drive 253; a drive in slot 2 is mapped as drive 254.

- When using RAID, we recommend that both SATA M.2 drives are the same capacity. If different capacities are used, the smaller capacity of the two drives is used to create a volume and the rest of the drive space is unusable.

JBOD mode supports mixed capacity SATA M.2 drives.

- Hot-plug replacement is not supported. The server must be powered off.

- Monitoring of the controller and installed SATA M.2 drives can be done using Cisco IMC. They can also be monitored using other utilities such as UEFI HII, PMCLI, XMLAPI, and Redfish.

- The SATA M.2 drives can boot in UEFI mode only. Legacy boot mode is not supported.

- If you replace a single SATA M.2 drive that was part of a RAID volume, rebuild of the volume is auto-initiated after the user accepts the prompt to import the configuration. If you replace both drives of a volume, you must create a RAID volume and manually reinstall any OS.

- We recommend that you erase drive contents before creating volumes on used drives from another server. The configuration utility in the server BIOS includes a SATA secure-erase function.

- The server BIOS includes a configuration utility specific to this controller that you can use to create and delete RAID volumes, view controller properties, and erase the physical drive contents. Access the utility by pressing F2 when prompted during server boot. Then navigate to Advanced > Cisco Boot Optimized M.2 RAID Controller.

Supported Storage Controllers and Cables

This server supports a single, PCIe-style, SAS RAID or HBA controller that plugs into a dedicated internal riser. Alternatively, the server has a software-based SATA RAID controller embedded in the system.

Note

Do not mix controller types in the server. Do not use the embedded SATA controller and a hardware-based RAID controller card at the same time. This combination is not supported and could result in data loss.

Note

NVMe PCIe SSDs cannot be controlled by a SAS/SATA RAID controller.

This server supports the RAID and HBA controller options and cable requirements shown in the following table.

Storage Controller Card Firmware Compatibility

Firmware on the storage controller (RAID or HBA) must be verified for compatibility with the current Cisco IMC and BIOS versions that are installed on the server.

RAID Backup (Supercap)

This server supports installation of one supercap unit. The unit mounts to a bracket in-line with the fan modules.

The optional SCPM provides approximately three years of backup for the disk write-back cache DRAM in the case of a sudden power loss by offloading the cache to the NAND flash.

For supercap unit replacement instructions, see Replacing the Supercap (RAID Backup).

Write-Cache Policy for Cisco 12G SAS Modular RAID Controller

For this server and other Cisco Generation M5 servers, the default write-cache policy for the Cisco Modular RAID controller is Write Through (irrespective of the presence of a charged supercap or “good BBU”). This utilizes the optimal performance characteristics of the controller.

The write policy can be set to Write Back, if preferred. You can set the write policy using the following methods:

- For standalone servers, use the Cisco IMC interface to set Virtual Drive Properties > Write Policy. See the “Managing Storage Adapters” section in your Cisco IMC Configuration Guide.

Cisco IMC GUI and CLI Configuration Guides

- For Cisco UCS-integrated servers, use the Cisco UCS Manager interface to set the write-cache policy as part of virtual drive configuration in your storage profile.

Cisco UCS Manager Configuration Guides

- Use the LSI Option ROM Configuration Utility.

Mixing Drive Types in RAID Groups

The following table lists the technical capabilities for mixing hard disk drive (HDD) and solid state drive (SSD) types in a RAID group. However, see the recommendations that follow for the best performance.

Mixing Drive Types

Drive Type Mixing Best Practices

For the best performance follow these guidelines:

- Use either all SAS or all SATA drives in a RAID group.

- Use the same capacity for each drive in the RAID group.

- Never mix HDDs and SSDs in the same RAID group.

Storage Controller and Backplane Connectors

This section describes cabling connections for the storage controllers and the backplane. The SAS/SATA cables are factory-installed and are used for all supported internal controllers in the SFF 10-drive of the SE-CL-L3 .

This section also contains diagrams that show the cable-to-drive mapping.

Embedded RAID

This SW RAID option can control up to 8 SATA drives in the SFF 10-drive version and up to 4 SATA drives in the LFF 4-drive version.

This embedded RAID option requires that you have a SATA interposer card installed in internal mRAID riser 3. Use the SAS/SATA cables that came with the server.

1. Connect SAS/SATA cable A1 from the A1 interposer connector to the A1 backplane connector.

2. Connect SAS/SATA cable A2 from the A2 interposer connector to the A2 backplane connector.

Note

See the following figures that illustrate cable connections and which drives are controlled by each cable. In the SFF 10-drive version, drives 5 and 10 cannot be controlled by the embedded SATA RAID controller.

Embedded SATA RAID Controller

This server includes an embedded MegaRAID controller that supports RAID levels 0 and 1. The primary controller can control up to eight front-loading SATA-only drives. The secondary controller can control two internal M.2 SATA drives.

Note

The VMware ESX/ESXi operating system is not supported with the embedded SATA MegaRAID controller in SW RAID mode. You can use VMWare in AHCI mode.

Note

The Microsoft Windows Server 2016 Hyper-V hypervisor is supported for use with the embedded MegaRAID controller in SW RAID mode, but all other hyperviors are not supported. All Hypervisors are supported in AHCI mode.

Note

You cannot control the M.2 SATA SSDs in the server with a HW RAID controller.

- Embbeded SATA RAID Requirements

- Embedded SATA RAID Controller Considerations

- Embedded SATA RAID: Two SATA Controllers

- Enabling SATA Mode For the Embedded Controllers

- Accessing the Software RAID Configuration Utility

Embbeded SATA RAID Requirements

The embedded SATA RAID controller requires the following items:

- Interposer card UCSC-SATAIN-220M5. This must be installed in internal mRAID riser 3.

- The SAS/SATA cables that are preinstalled in the chassis.

- Primary controller: SATA drives only (up to eight, in front drive bays 1–8).

- Secondary controller: M.2 mini-storage module with two SATA M.2 SSDs.

- The embedded SATA RAID controllers must be enabled in the server BIOS. If you ordered the server with embedded SATA RAID, it is enabled at the factory.

- (Optional) LSI MegaSR drivers for Windows or Linux.

- The software RAID controller requires UEFI boot mode; Legacy boot mode is not supported.

- If you use an embedded RAID controller with Linux, both the pSATA and the sSATA controller must be set to LSI SW RAID mode.

Embedded SATA RAID Controller Considerations

Note the following considerations:

- The default setting for this embedded controller hub is SATA RAID 0, 1, and 10 support for up to eight front-loading SATA drives, and up to two internal M.2 SATA drives. The hub is divided into two SATA controllers that have different functions. See Embedded SATA RAID: Two SATA Controllers.

- When you order the server with this embedded controller, the controller is enabled in the BIOS. Instructions for enabling the controller are included for the case in which a server is reset. See Enabling SATA Mode For the Embedded Controllers.

- You cannot downgrade from using a hardware RAID controller card to using the software RAID embedded controller (see RAID Controller Migration).

Caution

Data migration from software RAID (embedded RAID) to hardware RAID (a controller card) is not supported and could result in data loss. Migrations from software RAID to hardware RAID are supported only before there is data on the drives, or when there are no drives in the server.

- The required drivers for this controller are already installed and ready to use with the LSI SWRAID Configuration Utility.

Embedded SATA RAID: Two SATA Controllers

The embedded RAID platform controller hub (PCH) is split into two controllers: primary SATA (pSATA) and secondary SATA (sSATA). These two controllers are seen as separate RAID controllers in the Cisco IMC interface and are configurable separately.

- SFF 10-drives server SE-CL-L3 :

- The pSATA controller controls up to eight front SATA drives (drive bays 1–8).

- The sSATA controller controls two internal SATA M.2 drives, when they are present in the M.2 mini-storage module option.

- If the M.2 mini-storage module is not present, or if M.2 NVMe drives are installed in the mini-storage module, the sSATA controller is automatically disabled.

Enabling SATA Mode For the Embedded Controllers

This procedure uses the server's BIOS Setup Utility.

Note

If you use an embedded RAID controller with Linux, both the pSATA and the sSATA controller must be set to LSI SW RAID mode.

Procedure

Step 1

Boot the server and press F2 when prompted to enter the BIOS Setup utility.

Step 2

Set the SATA mode:

1. Choose the Advanced tab, and then choose LOM and PCIe Slots Configuration.

2. For the primary pSATA controller, select pSATA and then choose one of the options from the dialog:

- LSI SW RAID—Enable the embedded pSATA RAID controller.

Note

This menu option does not appear when the server is set to boot in Legacy mode (UEFI mode is required). To change the boot mode, use the BIOS setting for Boot Options > Boot Mode.

- Disabled—Disable the embedded pSATA RAID controller.

3. For the secondary sSATA controller, select M.2 and then choose one of the options from the dialog:

- LSI SW RAID—Enable the embedded sSATA RAID controller for control of internal SATA M.2 drives.

Note

This menu option does not appear when the server is set to boot in Legacy mode (UEFI mode is required). To change the boot mode, use the BIOS setting for Boot Options > Boot Mode.

Note

This menu option does not appear when the server has no M.2 mini storage module, or when no SATA M.2 drive is installed in the mini-storage module.

- AHCI—Enable control of the internal SATA M.2 drives by AHCI through your OS rather than the embedded RAID controller.

- Disabled—Disable the embedded sSATA RAID controller.

Step 3

Press F10 to save your changes and exit the utility.

Accessing the Software RAID Configuration Utility

To configure RAID settings for the embedded SATA RAID controllers, use the utility that is built into the BIOS. Each controller is controlled by its own instance of the utility.

Procedure

Step 1

Boot the server and press F2 when prompted to enter the BIOS Setup utility.

Step 2

Choose the Advanced tab.

Step 3

Select the instance of the utility that is for the controller that you want to manage (primary or secondary):

- For the pSATA controller, select LSI Software RAID Configuration Utility (SATA).

- For the sSATA controller, select LSI Software RAID Configuration Utility (sSATA).
