Cisco UCS C22 M3 vs C220 M7
The UCS C22 M3 is an end-of-life entry 1RU server on Xeon E5-2400, and the UCS C220 M7 is its modern 1RU replacement. The C220 M7 brings 4th/5th Gen Xeon Scalable CPUs, DDR5, NVMe, and PCIe Gen5, so C22 M3 fleets should refresh to the C220 M7.

Cisco UCS C22 M3 vs Cisco UCS C220 M7: spec comparison
| Spec | Cisco UCS C22 M3 | Cisco UCS C220 M7 |
|---|---|---|
| Form factor | 1RU rack | 1RU rack |
| Sockets | 2 | 2 |
| CPU family | Intel Xeon E5-2400 | 4th/5th Gen Intel Xeon Scalable |
| Max cores per socket | 8 (E5-2400) | Up to 60 |
| Memory type | DDR3 | DDR5 up to 5600 MT/s |
| DIMM slots | 12 | 32 |
| Max memory | Up to 384 GB | Up to 4 TB |
| Drive bays | Up to 8 SFF / 4 LFF | Up to 10 SFF (SAS/SATA/NVMe) |
| PCIe generation | PCIe Gen3 | PCIe Gen5 |

| Lifecycle status | End-of-life | Current, fully supported |
Choose Cisco UCS C22 M3 if
Keep a C22 M3 only for a non-critical legacy workload under existing support that you are not ready to refresh. It is end-of-life on DDR3 and Gen3 PCIe and should not be deployed new.
Choose Cisco UCS C220 M7 if
Choose the C220 M7 for entry and general-purpose 1RU refresh. It massively raises core count, memory capacity, and storage performance over the C22 M3 while staying in the same 1RU footprint, and it is Intersight-ready and TAA-compliant for federal procurement.
Verdict
Migrate to the UCS C220 M7. In the same 1RU footprint it replaces the end-of-life C22 M3 with modern Xeon Scalable CPUs up to 60 cores per socket, up to 4 TB of DDR5, NVMe, and PCIe Gen5. The consolidation, performance, and current support make the refresh straightforward.
Frequently asked questions
Is the UCS C22 M3 end of life?
Yes. The UCS C22 M3 is an end-of-life entry-level rack server based on Intel Xeon E5-2400 processors and DDR3 memory. Cisco no longer sells it, and workloads should move to a current C-Series M7 server.
What is the modern replacement for the UCS C22 M3?
The UCS C220 M7 is the current 1RU 2-socket general-purpose rack server and the natural successor to entry-level M3 servers like the C22 M3.
How much memory does the C220 M7 support?
The C220 M7 provides 32 DDR5 DIMM slots for up to 4 TB of memory at speeds up to 5600 MT/s, compared with 12 DDR3 slots and up to 384 GB on the C22 M3.
Is the UCS C220 M7 TAA-compliant for government?
Yes. Cisco UCS C220 M7 rack servers are offered in TAA-compliant configurations for US federal procurement and can be purchased through authorized partners on government contract vehicles.
