Summary of Node Features

.

Table 1-1 Cisco HX220c M4 HyperFlex Node Features

Feature
Description

Chassis

One rack-unit (1RU) 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

Supported 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 LOM

Dedicated socket that 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 AC power supplies: 770 W AC each.

Redundant as 1+1. See Power Specifications.

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

Two horizontal PCIe4 expansion slots (single riser assembly).

InfiniBand

The bus slots in this node support the InfiniBand architecture.

Storage

Drives are installed into front-panel drive bays:

  • One housekeeping SSD for SDS logs in bay 1.
  • One solid state drive (SSD) caching drive in bay 2.
  • Persistent data drives:

–blank.gif HX220c: Up to six HDD persistent data drives in bays 3–8.

–blank.gif HX220c All-Flash: Up to six SSD persistent data drives in bays 3–8.

See Cisco HX220c All-Flash HyperFlex Nodes Overview for more information.

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.

Disk Management

The node has a dedicated internal riser for a PCIe-style Cisco modular HBA card.

For a list of controller options and required cabling, see Supported HBAs and Required Cables.

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 HX220c All-Flash HyperFlex Nodes Overview

The HX220c All-Flash HyperFlex node contains all SSDs, rather than the hybrid mix of SSDs and HDDs that is used in the HX220c 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.
  • HX220c All-Flash HyperFlex nodes are ordered as specific All-Flash PIDs; All-Flash configurations are supported only on those PIDs.
  • Conversion from hybrid HX220c configuration to HX220c All-Flash configuration is not supported.
  • Mixing hybrid HX220c HyperFlex nodes with HX220c All-Flash HyperFlex nodes within the same HyperFlex cluster is not supported.

See HX220c Drive Configuration Comparison for specifics about drive PIDs supported in the node types.
