Cisco Announces The UCS B200 M6 Blade Server

(Updated 4.13.2021) Cisco announced on Tuesday, April 6th, 2021, the UCS B200 M6 blade server.  Let’s take a look at what was revealed.

UCS B200 M6 Overview

The B200 M6 is built upon the 3rd Gen Intel Xeon Scalable Processor and offers the following:

  • Up to 2 x 3rd Generation Xeon Scalable Processors (with up to 40 cores per socket)
  • Up to 32 DIMMs (16 per CPU)
  • Support for Intel Optane persistent memory (x16)
  • Cisco UCS Virtual Interface Card (VIC) 1440 modular LAN on Motherboard (mLOM).
  • Two mezzanine card adapters: One rear slot for VIC (Cisco UCS VIC 1480 or port expander); One front dedicated slot for a Cisco FlexStorage RAID controller, Cisco FlexStorage passthrough, or Cisco® M.2 RAID controller
  • (Updated 4.8.2021) Up to two SSD or NVMe disk drives or up to four M.2 drives  (note, you can’t use SSD/NVMe and the M.2 – it’s one or the other.)
  • (Updated 4.13.2021) The newly released spec sheet states “The B200 M6 has a power cap of 960W for all combinations of components.”  This is concerning, however.  Simple math on that shows: 960W x 8 servers = 7,680W yet the UCS 5108 only supports 4 x 2500W power which is equal to 5,000W of “redundant” power.  Something doesn’t add up on this one.

For further details, please visit the UCS B200 M6 Datasheet or (Updated 4.13.2021) for full configuration details, visit the Spec Sheet.
