Cisco UCS B200 M3 vs UCSX-210C-M7
The UCS B200 M3 is an end-of-life half-width blade built on Intel Xeon E5-2600 v2 and DDR3; its modern Cisco replacement is the UCS X210c M7 compute node in the X9508 chassis, with 4th/5th Gen Xeon Scalable CPUs, DDR5, NVMe, and up to 8 TB of memory. Migrate B200 M3 estates to the X210c M7 on UCS X-Series.

Cisco UCS B200 M3 vs Cisco UCS X210c M7: spec comparison
| Spec | Cisco UCS B200 M3 | Cisco UCS X210c M7 |
|---|---|---|
| Form factor | Half-width blade (UCS 5108) | Compute node (UCS X9508) |
| CPU family | Xeon E5-2600 / v2 | 4th/5th Gen Xeon Scalable |
| Max cores per CPU | 12 (E5-2600 v2) | Up to 64 |
| Memory type | DDR3 | DDR5 (4800/5600) |
| DIMM slots | 24 | 32 |
| Max memory | 768 GB | 8 TB (256 GB DIMMs) |
| Internal drives | 2 (SAS/SATA/SSD) | Up to 6 SAS/SATA/NVMe + 2x M.2 |
| NVMe support | No | Yes (all-NVMe option) |
| Fabric per node | Up to 2x 10GbE (VIC 1240) | Up to 100 Gbps |
| Chassis | UCS 5108 (6RU) | UCS X9508 (7RU) |
| Lifecycle status | End of Life | Current, actively sold |
Choose Cisco UCS B200 M3 if
Keep the B200 M3 only to fill an existing 5108 chassis short-term; it cannot run current ESXi/Windows releases on a supported basis and is well past its refresh window.
Choose Cisco UCS X210c M7 if
Choose the X210c M7 for any new or consolidated virtualization, VDI, database, or container workload that benefits from DDR5 capacity, NVMe, modern Xeon core counts, and Intersight management.
Verdict
The B200 M3 is a DDR3, Xeon v2 blade that is end of life and dramatically under-powered for current workloads. The X210c M7 is the modern X-Series successor, multiplying memory capacity to 8 TB, adding NVMe, modern Xeon Scalable cores, and 100G fabric, and it consolidates many M3 blades into far fewer nodes. Migrate B200 M3 estates to the X210c M7 in the X9508 chassis.
Frequently asked questions
Is the Cisco UCS B200 M3 end of life?
Yes. The B200 M3 has passed end of sale and software/hardware support milestones. It is built on Xeon E5-2600 v2 and DDR3 and is no longer a supported platform for current hypervisor and OS releases.
What replaces the UCS B200 M3?
Cisco's current successor is the UCS X-Series. The X210c M7 compute node in the UCS X9508 chassis is the modern equivalent of a half-width B-Series blade and is the recommended migration target.
Can I reuse my UCS 5108 chassis with the X210c M7?
No. The X210c M7 is a UCS X-Series node and requires the UCS X9508 chassis with X-Series fabric. The B-Series 5108 chassis cannot host X-Series nodes, so a chassis refresh is part of the migration.
How many B200 M3 blades does one X210c M7 replace?
It depends on workload, but the X210c M7's far higher core counts, 8 TB memory ceiling, and NVMe storage typically let a single node consolidate several B200 M3 blades, reducing chassis count, power, and licensing.
