878724-B21

HPE 878724-B21 is a ProLiant DL385 Gen10 7451 2P 64GB-R P408i-a 24SFF SAS 2x800W PS Perf Server. It belongs to the ProLiant DL385 Gen10 Servers range.

What to check before you buy. Three things decide whether a server will suit the job. The generation, because the processors, memory and controllers that fit one generation generally do not fit the next even where the chassis looks identical. The drive configuration, because a chassis built for small form factor disks cannot take large form factor ones without a different cage and backplane. And how it is specified to be populated, since a second processor usually needs its own heatsink and may enable memory slots that are otherwise unusable. It is also worth asking what is physically included: rails, bezel, drive carriers and the remote management licence are all commonly sold separately from the chassis.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. If you are unsure whether this is the right part, give us the model it is going into and we will confirm it. Quotes by the next working day.

This is HPE part 878724-B21: an HPE ProLiant DL385 Gen10, supplied as a complete, pre-configured server rather than a chassis to specify yourself — AMD EPYC 7451; 64 GB RDIMM; 24 x 2.5-inch (SFF).

The HPE ProLiant DL385 is HPE’s two-socket AMD platform, where the draw is core count and memory bandwidth per socket.

All 2 sockets are populated in this build, so the full memory capacity and the expansion slots tied to the upper processors are available rather than waiting on an upgrade.

What is in this configuration

The P408i-a storage controller

The P408i-a is a hardware RAID controller with eight internal ports and a write cache, which is what most general-purpose servers actually want. The cache is what makes write-heavy workloads behave, and it supports SAS as well as SATA.

This server ships with registered memory

The -R suffix means RDIMM, registered memory, which is what mainstream ProLiant servers use. It allows far higher total capacity than unbuffered memory and it is what you want if the server will grow. Registered and unbuffered memory cannot be mixed, so any upgrade needs to be RDIMM too.

Power supplies, and whether this build is redundant

This build ships with 2 x 800 W power supplies, which means it is genuinely redundant: lose one supply, or one feed, and the server keeps running. Worth feeding them from separate circuits if the rack allows it, since two supplies on one failed circuit protect against nothing.

Drive bays

These are 2.5-inch (SFF) bays. Small-form-factor bays give you more drives in the same chassis, which suits SSDs and anything that needs spindles or IOPS rather than raw terabytes. The bays are hot-plug, so a failed drive can be replaced with the server running.

Worth checking before you order

• Pre-configured does not mean fixed. We can change the memory, drives, controller or network adapters before despatch, which is usually cheaper than buying the base build and upgrading it afterwards. Tell us what it needs to do.
• Drives are not normally included in these configurations. Confirm what you need and we will quote them with the server so the caddies and firmware match.
• Tell us what this server is replacing and what it has to run, and we will confirm this build is the right one rather than just the one you found.
