876915-L21

HPE 876915-L21 is an ML110 Gen10 Xeon-B 3104 FIO Kit. It belongs to the ProLiant ML110 Server Processors range. Matching on sight is unreliable here. The part number is what determines whether it will work in a given chassis.

Adding a second one. A matched pair means the same model, not merely the same family or clock speed. The kit should include the heatsink; the fans frequently do not come with it and have to be ordered alongside. Give us the server model and what is fitted today and we will confirm the complete set.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. Quote the equipment it is for when you ask and we will verify the fit first. We come back by the next working day.

This is the 876915-L21 processor kit: an Intel Xeon Bronze 3104 for the HPE ProLiant ML110 Gen10.

Bronze is the entry tier, for servers whose job is to exist reliably rather than to work hard — a file share, a domain controller, a small application host.

Specifications

We would rather confirm the core count, clock and power figures for your specific kit than publish an approximation you might order against. Ask and you will have them the same day.

Generation, and why it matters here

This is a 1st Generation Xeon Scalable processor, the family Intel shipped as Skylake-SP. It shares the LGA3647 socket with the 2nd Generation parts (Cascade Lake, the 5200, 6200 and 8200 series), which means the two generations look interchangeable and are not always so: whether a particular server accepts both depends on its system board and its firmware level.

So if you are adding to or upgrading an existing machine, tell us what is already fitted and we will confirm the combination before you order. Gen10 processors are in no case interchangeable with Gen9 or with Gen10 Plus servers, which use different sockets.

This is an L21 factory-installed kit

The -L21 part number is HPE’s FIO (factory-installed option) kit, ordered alongside a configure-to-order server so the processor arrives already fitted with the matching heatsink and airflow parts. The equivalent -B21 is the standard option kit for a server you already have. The processor is the same either way; the supply route differs. Upgrading an existing machine rather than buying a new one? Ask us for the -B21 version.

Fitment

HPE lists this kit for the HPE ProLiant ML110 Gen10, the single-socket tower server, built for an office or a small comms room rather than a rack.

This is a single-socket server. There is no second processor to add and no pairing to get wrong, which also means the processor you choose now is the processor the machine keeps — size it for where the workload is going, not only for where it is today.

Worth checking before you order

• Ask us for the core count, clock and TDP before you order. We will confirm them from HPE’s documentation for this exact part number rather than have you work from a figure found elsewhere.
• Mixing processor generations in one server is a firmware question, not just a socket question. Confirm with us before combining Skylake and Cascade Lake parts.
• Memory is populated per processor, across six channels per socket. An unbalanced DIMM layout costs real bandwidth, so plan the full memory configuration alongside the processor.
• 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 serial or product number and what it runs, and we will confirm the processor and quote the alternatives.
