P06656-L21

HPE P06656-L21 is a DL20 Gen10 Intel Xeon E-2174G (3.8GHz/4-core/71W) FIO Processor Kit. The part number is the reliable way to identify it, because accessories of this kind are often visually identical across generations that are not interchangeable.

Matching the server. Processor kits are tied to a server generation and often to a specific chassis. Where a second processor is being added, the kit usually has to come with the matching heatsink and sometimes extra fans, and both processors must be the same model. Check the maximum thermal rating the chassis supports before choosing.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. Tell us the chassis or model it has to work with and we will confirm the part before anything ships. Quotes go out the same or next working day.

An Intel Xeon E-2174G for the HPE ProLiant DL20 Gen10, supplied as HPE kit P06656-L21: 4 cores and a 3.8 GHz base clock.

4 cores at 3.8 GHz base is a clock-first part, and the usual reason to choose one is licensing. A great deal of database and enterprise software is still priced per core, so fewer faster cores can cost far less to licence while finishing the same work. It also suits anything with a single-threaded bottleneck, where extra cores buy you nothing at all.

Specifications

Platform and generation

This processor is from the Intel Xeon E-2100 family. Processor kits are tied to a server generation, and the socket is only part of the story: two generations can share a socket and still not accept each other’s processors, because the system board and firmware decide what will actually run.

This is an L21 factory-installed kit

The -L21 part number is HPE’s FIO (factory-installed option) kit, meant to be ordered with a configure-to-order server so the processor arrives already fitted with its heatsink and the airflow parts the chassis expects. The matching -B21 is the standard option kit for a server you already own. Same processor either way; what differs is how it is supplied.

Worth checking before you order

• Adding a processor to a multi-socket server? Every processor in the machine must be the same model. Send us the part number already fitted and we will confirm the match.
• Memory is populated per processor. Plan the DIMM layout alongside the processor, since an unbalanced configuration costs real bandwidth.
• Update system firmware before or alongside a processor change. A server on older firmware may not recognise a newer stepping.
• Not certain this is the right part? Give us the server’s product or serial number and what it runs, and we will confirm the processor and quote the alternatives.
