Which processor option is supported in the Cisco UCS C420 M3 Server?

The UCS C420 M3 physically supports up to four processor sockets, so restricting it to only two E5-4600 processors understates the server's full processor capacity.

The Intel Xeon E7-4800 series targets different high-end server platforms and is not the designated processor family for the Cisco UCS C420 M3.

The Cisco UCS C420 M3 is architected as a 4-socket server platform and the Intel Xeon E5-4600 series is the supported processor family for this model. Intel designed the E5-4600 line specifically for multi-socket scalable configurations, making it the correct match for the C420 M3's 4-socket design. This processor support enables the high core counts and large memory capacity needed for memory-intensive enterprise workloads.

The Intel Xeon E7-8800 series is used in higher-end platforms such as the Cisco UCS C460 M4, not the UCS C420 M3, which uses the E5-4600 family instead.
