Cisco UCS B22 M3 vs UCS X210c M7
The UCS B22 M3 is an end-of-life value blade for the 5108 chassis, and the UCS X210c M7 compute node is the modern X-Series replacement. The X210c M7 moves to 4th/5th Gen Xeon Scalable CPUs, DDR5, and NVMe in the future-ready X9508 chassis, so B22 M3 fleets should migrate to X-Series.
Cisco UCS B22 M3
End-of-life value half-width blade server for the UCS 5108 chassis.

- 32 DDR5 DIMM slots, up to 8 TB
- Up to 6 NVMe/SAS/SATA drives, GPU-capable front mezzanine
- Intersight-managed; TAA-compliant
Cisco UCS B22 M3 vs Cisco UCS X210c M7: spec comparison
| Spec | Cisco UCS B22 M3 | Cisco UCS X210c M7 |
|---|---|---|
| Form factor | Half-width blade (UCS 5108) | Compute node (UCS X9508) |
| Sockets | 2 | 2 |
| CPU family | Intel Xeon E5-2400 / v2 | 4th/5th Gen Intel Xeon Scalable |
| Max cores | Up to 20 total | Up to 64 per socket |
| Memory type | DDR3 up to 1600 MHz | DDR5 up to 5600 MT/s |
| DIMM slots | 12 | 32 |
| Max memory | Up to 384 GB | Up to 8 TB |
| Internal drives | 2 hot-plug | Up to 6 (U.2/U.3 NVMe/SAS/SATA) |
| GPU support | No | Yes (front mezzanine GPUs) |
| Management | UCS Manager | Cisco Intersight |
| Lifecycle status | End-of-life | Current, fully supported |
Choose Cisco UCS B22 M3 if
Keep a B22 M3 only to fill an existing 5108 chassis short-term while you plan an X-Series migration. As a DDR3, E5-2400 end-of-life blade, it should not be part of any new build.
Choose Cisco UCS X210c M7 if
Choose the X210c M7 for blade/compute refresh and new deployments. Its Xeon Scalable core counts, 8 TB DDR5, NVMe, and GPU support in the future-ready X9508 chassis consolidate many B22 M3 blades, and it is Intersight-managed and TAA-compliant for federal buyers.
Verdict
Migrate to the UCS X210c M7. It replaces the end-of-life B22 M3 with modern Xeon Scalable CPUs, up to 8 TB of DDR5, NVMe storage, and GPU options in the future-ready X9508 chassis. A single X210c M7 consolidates multiple B22 M3 blades while moving management to Intersight.
Frequently asked questions
Is the UCS B22 M3 end of life?
Yes. The UCS B22 M3 is an end-of-life value blade based on Intel Xeon E5-2400 processors and DDR3 memory. Cisco no longer sells it, and workloads should be migrated to the current X-Series.
What replaces the UCS B22 M3 blade?
Cisco's modern modular compute platform is the UCS X-Series. The X210c M7 compute node, housed in the UCS X9508 chassis, is the successor to legacy B-Series blades like the B22 M3.
Can I put an X210c M7 in my existing UCS 5108 chassis?
No. The X210c M7 is a UCS X-Series compute node that installs in the UCS X9508 chassis, not the older 5108 blade chassis. Migrating means moving to X-Series chassis and fabric, typically managed by Intersight.
How much more memory does the X210c M7 support than the B22 M3?
The X210c M7 offers 32 DDR5 DIMM slots for up to 8 TB of memory, compared with 12 DDR3 slots and up to 384 GB on the B22 M3, a large increase in both capacity and bandwidth.
