HPE P23550-B21 Intel Xeon Silver 4214R Processor Kit for ProLiant DL380 Gen10

P23550-B21 is HPE's option kit for adding an Intel Xeon Silver 4214R to a ProLiant DL380 Gen10; PartSurfer lists the processor itself as spare P19245-001, with a standard heat sink (875070-001) and a standard fan module (875075-001) in the kit. Intel's specifications give the 4214R 12 cores and 24 threads at 2.40 GHz base and 3.50 GHz turbo, 16.5 MB of cache, a 100 W TDP, 2 UPI links and DDR4-2400 memory support up to 1 TB per socket; it is a 2nd Gen Xeon Scalable (Cascade Lake) part launched in Q1 2020.

HPE ships processors above 130 W, plus a short list of exceptions, with the high-performance heatsink; at 100 W the 4214R kit carries the standard one. As a -B21 kit it is meant for the second socket, with the -L21 version used for the first in factory builds; HPE adds two fans in the -B21 kit and forbids mixing processor models. HPE also states that field upgrades from 1st Gen (x1xx) to 2nd Gen (x2xx) processors are not supported, so a 4214R pairs with a server already running 2nd Gen Xeon Scalable processors.

Its nearest sibling is the 4214 (kit P02493-B21): Intel lists 12 cores at 2.20 GHz and 85 W, launched Q2 2019. Intel has issued an End of Servicing Updates notice for the 4214R, with updates ending June 30, 2025. HPE pre-configured DL380 Gen10 models built on the 4214R include P56963-B21, P24842-B21. Before ordering, confirm the host is a ProLiant DL380 Gen10 and read the installed processor model; it must also be a 4214R.

The 4214 kit P02493-B21 is the earlier version, and the pre-configured P56963-B21 uses this 4214R; see HPE ProLiant DL380 Gen10 spare parts.
