Summary of Server Features

The following table lists a summary of server features.

Feature

Description

Chassis

Four rack-unit (4RU) chassis

Central Processor

The server supports one removable CPU module with two CPUs from the Intel Xeon Processor Scalable Family. This includes CPUs from the following series:

  • Intel Xeon Silver 4XXX Processors

  • Intel Xeon Gold 5XXX Processors

  • Intel Xeon Gold 6XXX Processors

  • Intel Xeon Platinum 8XXX Processors

Memory

Each of the CPUs support up to 12 DIMMs for a total of 24 DIMMs.

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/10-Gb Ethernet LAN ports, or a Cisco virtual interface card.

Network and management I/O

The network and management I/O ports for this server are on a removeable I/O module:

  • One 10/100/1000 Ethernet dedicated management port (RJ-45 connector)

  • One 10/100/1000 Ethernet private inter-chassis port (RJ-45 connector)

  • Two 1-Gb/10-Gb BASE-T Ethernet LAN ports (RJ-45 connectors)

  • One RS-232 serial port (DB-9 connector)

  • One VGA video connector port (DB-15 connector)

  • Three USB 3.0 ports

Front panel:

  • One front-panel keyboard/video/mouse (KVM) connector that is used with the KVM cable, which provides two USB 2.0, one VGA, and one DB-9 serial connector.

Power

Four power supplies, redundant as 3+1:

  • AC power supplies 1600 W AC each

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

ACPI

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

Cooling

Four hot-swappable fan modules with two fans in each for front-to-rear cooling.

PCIe I/O

Four vertical PCIe expansion slots on the chassis motherboard.

See PCIe Slot Specifications and Restrictions for specifications of the slots.

InfiniBand

The PCIe bus slots in this server support the InfiniBand architecture.

Storage, front-panel

The server can hold up to 24 front-loading, 2.5-inch drives.

Front drive bays are divided across 3 removable drive bay modules. Each drive bay module has 8 drive bays for a total of 24 front-loading drive bays.

  • All 24 front drive bays support SAS/SATA drives.

  • NVMe drives are supported in these six bays: 1, 2, 7, 8, 9, 17.

Storage, internal

The server has these internal storage options:

  • One USB 2.0 port on the chassis motherboard.

  • Mini-storage module socket on the I/O module board, optionally with either:

    • SD card carrier. Supports up to two SD cards.

    • M.2 SSD carrier. Supports two SATA M.2 SSDs.

  • One micro-SD card socket on the I/O module board.

Other removable media

A DVD drive module option is available in place of the right drive bay module.

Storage management

Front-loading storage: the server has a dedicated internal socket near the chassis front for a single storage controller card (RAID). This controller card can control up to 24 front-loading drives.

For a detailed list of storage controller options, see Supported Storage Controllers and Cables.

RAID supercap backup

There is a bracket on the chassis wall for a supercap unit that backs up a front RAID controller for front-loading drives.

Integrated video

Integrated VGA video.
