Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco UCS C225 M6 SFF Rack Server extends the capabilities of the Cisco Unified Computing System portfolio in a 1-Rack-Unit (RU) form factor with the addition of AMD CPUs as well as 16 DIMM slots per CPU for 3200-MHz DDR4 DIMMs with individual DIMM capacity points up to 256 GB. The maximum memory capacity for two CPUs is 8 TB (for 32 x 256 GB DDR4 DIMMs1).
There are several front drive and rear riser configurations, as listed below:
Front drives
● Option 1: Up to 10 SAS/SATA/NVMe drives (up to 4 of the drives can be NVMe)
● Option 2: Up to 10 NVME drives (All drives are NVMe)
Rear PCIe risers
● 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:
● Cisco 12G RAID controller with cache backup to control SAS/SATA drives, or
● Cisco 12G SAS passthrough HBA to control SAS/SATA drives
Note: NVMe drives are controlled directly from the CPUs.
The UCS C225 M6 server has a single 1 GbE management port. A modular LAN on motherboard (mLOM) / Open Compute Project (OCP) 3.0 module provides up to two 100 GbE ports. A connector on the front of the chassis provides KVM functionality.
The Cisco UCS C225 M6 server can be used either as a standalone or as part of the Cisco Unified Computing System, which unifies computing, networking, management, virtualization, and storage access into a single integrated architecture, enabling end-to-end server visibility, management, and control in both bare-metal and virtualized environments.
