Summary of Node Features

Table 1-1 lists a summary of node features.

.

Table 1-1 Cisco HX240c HyperFlex Node Features

Chassis

Two rack-unit (2RU) chassis.

Processors

Two Intel Xeon E5-2600 v3 or v4 Series processors.

Memory

24 DDR4 DIMM1 sockets on the motherboard (12 each CPU).

Multi-bit error protection

Multi-bit error protection is supported.

Baseboard management

BMC, running Cisco Integrated Management Controller (Cisco IMC) firmware.

Depending on your Cisco IMC settings, Cisco IMC can be accessed through the
1-Gb dedicated management port, the 1-Gb Ethernet LOM ports, or a Cisco virtual interface card.

Network and management I/O

The node provides these native connectors:

  • One 1-Gb Ethernet dedicated management port
  • Two 1-Gb BASE-T Ethernet LAN ports
  • One RS-232 serial port (RJ-45 connector)
  • One 15-pin VGA2 connector
  • Two USB3 3.0 connectors
  • One front-panel KVM connector that is used with the KVM cable, which provides two USB 2.0, one VGA, and one serial (DB-9) connector.

Modular I/O

A dedicated socket can be used to add an mLOM card for additional rear-panel connectivity.

WoL

1-Gb BASE-T Ethernet LAN ports support the wake-on-LAN (WoL) standard.

Power

Two power supplies:

  • AC power supplies optionally 650 W AC, 1200 W AC, or 1400 W AC each.
  • DC power supplies 930 W DC each.

Do not mix power supply types or wattages in the node.

Redundant as 1+1.

ACPI

The advanced configuration and power interface (ACPI) 4.0 standard is supported.

Cooling

Six hot-swappable fan modules for front-to-rear cooling.

PCIe I/O

Five horizontal PCIe4 expansion slots on two risers.

Riser 1 contains PCIe slots 1 and 2, plus one internal SATA SSD.

Riser 2 contains slots 4, 5, and 6.

InfiniBand

The InfiniBand architecture is supported by the bus slots.

Storage

The following storage disks:

  • One SSD cache drive in front bay 1.
  • Persistent data drives:

–blank.gif HX240c: Up to 23 HDD persistent data drives in bays 2–24.

–blank.gif HX240c All-Flash: Up to 10 SSD persistent data drives in bays 2–11. (With Cisco HX Release 2.0, 10 SSDs are supported.)

  • Two internal SATA SSDs for SDS logs in PCIe riser 1.

Internal USB

One internal USB 3.0 port on the motherboard that you can use with a USB thumb drive for additional storage.

SD cards

Two internal bays on the motherboard for up to two SD cards.

Disk Management

One Cisco UCS 12G SAS Modular HBA.

Native Video

VGA video resolution up to 1920 x 1200, 16 bpp at 60 Hz, and up to 256 MB of video memory.

1.DIMM = dual inline memory module

2.VGA = video graphics array

3.USB = universal serial bus

4.PCIe = peripheral component interconnect express

Cisco HX240c All-Flash HyperFlex Nodes Overview

The HX240c All-Flash HyperFlex node contains all SSDs, rather than the hybrid mix of SSDs and HDDs that is used in the HX240c HyperFlex node. Enterprise value SSDs are used for the persistent data drives. Enterprise high-endurance SSDs are used for the caching drives.

Note the following considerations and restrictions:

  • The minimum Cisco HyperFlex software required is Release 2.0 or later.
  • With Cisco HX Release 2.0, only 10 SSD persistent data drives are supported.)
  • HX240c All-Flash HyperFlex nodes are ordered as specific All-Flash PIDs; All-Flash configurations are supported only on those PIDs.
  • Conversion from hybrid HX240c configuration to HX240c All-Flash configuration is not supported.
  • Mixing hybrid HX240c HyperFlex nodes with HX240c All-Flash HyperFlex nodes within the same HyperFlex cluster is not supported.

See HX240c Drive Configuration Comparison for specifics about drive PIDs supported in the node types.
