828357-L21

HPE 828357-L21 is an ML150 GEN9 E5-2603V4 FIO KIT. It belongs to the ProLiant ML150 Server Processors range. 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.

This is the 828357-L21 processor kit: an Intel Xeon E5-2603V4 for the HPE ProLiant ML150, with 6 cores and a 1.7 GHz base clock.

6 cores at 1.7 GHz is the middle of the range and where most general-purpose servers sensibly land: enough for a working virtualisation host or a mid-sized database without paying what the top bins cost.

It carries 15 MB of cache, which matters more than clock speed for workloads whose working set nearly fits in it — query-heavy databases and in-memory analytics especially.

Specifications

Platform and generation

This processor is from the Intel Xeon E5 v4 family, on the FCLGA2011-v3 socket. 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.

We have this kit listed in our HPE ProLiant ML150 range, but the record does not state which generation of that server it was built for, and kits in this range span more than one. Rather than guess, tell us the server’s product or serial number and we will confirm the fit in writing before anything ships.

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.

The product record for this part also marks it factory integrated, which agrees with the -L21 suffix.

Worth checking before you order

• Confirm the server generation with us first. We will check this part against your exact machine rather than have you work it out from the socket alone.
• 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.
• This is a FCLGA2011-v3 part and will not fit a server built for a different socket, whatever the model numbers suggest.
• 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.
