Overview

Overview

The Cisco UCS C220 M6 server is a one-rack unit server that can be used standalone, or as part of the Cisco Unified Computing System, which unifies computing, networking, management, virtualization, and storage access into a single integrated architecture. Cisco UCS also enables end-to-end server visibility, management, and control in both bare metal and virtualized environments. Each Cisco UCS C220 M6 server supports:

  • a maximum of two 3rd Generation Intel Xeon processors.

  • 32 DDR4 DIMMs (16 per CPU) for a total system memory of either 8 TB (32 256 GB DDR4 DIMMs) or 12 TB (16 x 256 GB DDR4 DIMMs1 and 16 x 512 GB Intel® Optane™ Persistent Memory Module.

    (PMEMs)).

  • 3 PCI Express riser connectors, which provide slots for “full height” and “half height” PCI-e adapters.

  • Two Titanium (80 PLUS rated) power supplies with support for N and N+1 power redundancy modes.

  • 2 10GBase-T Ethernet LAN over Motherboard (LOM) ports for network connectivity, plus one 1 Gigabit Ethernet dedicated management port

  • One mLOM card provides 2 100 Gig Ethernet ports

  • One KVM port on the front of the server.

  • Two different front-loading hardware configurations are available:

    • The Cisco UCS C220 M6 SFF (UCSC-C220-M6S): This model supports only small form-factor (SFF) drives and has a 10-drive backplane. Supports up to 10 front-loading 2.5-inch SAS/SATA drives, and up to 4 of the drives can be NVMe.

    • The Cisco UCS C220 M6 NVMe (UCSC-C220-M6N): This model supports only small form-factor (SFF) drives and has a 10-drive backplane. Supports up to 10 front-loading 2.5-inch NVMe-only SSDs.

  • Rear PCI risers are supported as one to three half-height PCIe risers, or one to two full-height PCIe risers.

  • The server provides an internal slot for one of the following:

    • SATA Interposer to control SATA drives from the PCH (AHCI), or

    • Cisco 12G RAID controller with cache backup to control SAS/SATA drives, or

    • Cisco 12G SAS pass-through HBA to control SAS/SATA drives

Cisco UCS C220 M6 Server Rear Panel Features

The rear panel features can be different depending on the number and type of PCIe cards in the server.

By default, single CPU servers come with only one half-height riser 1 installed, and dual CPU servers support all three half-height risers.

Rear PCIe risers can be one of the following configurations:

  • Half-height risers:

    • one half-height, ¾ length riser (not shown). With this configuration, PCIe slot (slot 1) supports one half-height, ¾ length, x16 lanes PCIe card and is controlled by CPU 1.

    • three half-height, ¾ length risers. See "UCS C220 M6 Server Rear Panel, Half Height, ¾ Length PCIe Cards" below.

  • Full-height risers: Two full height, ¾ length risers. See "Cisco UCS C220 M6 Server Rear Panel, Full Height, ¾ Length PCIe Cards" below.


Note

For definitions of LED states, see Rear-Panel LEDs.
