  • Hot-pluggable design enables drive swaps without downtime
  • Compatible with HP ProLiant XL190r Gen9 servers

Purpose-built enterprise storage

The HPE 797289-B21 is a 400GB solid-state drive designed for HP ProLiant XL190r Gen9 servers. It uses a SAS 12Gb/s interface in a 3.5-inch hot-pluggable form factor. The drive targets mainstream endurance workloads in compatible server environments.

Sustained workload behaviour

Mainstream endurance rating means the drive handles steady mixed read-write traffic typical of virtualisation, databases and logging. The SAS 12Gb/s link maintains consistent throughput without the latency spikes seen on slower interfaces. Hot-plug support allows replacement without powering down the server.

Upgrade context

This SSD replaces mechanical SAS drives in the XL190r Gen9, cutting access latency and raising IOPS for the same 3.5-inch bay. The jump is worth it when application response time matters more than raw capacity per pound. Buyers needing higher write endurance or larger capacities should look elsewhere.

Questions about this item

How much power does the 400GB 12G SAS 3.5in LP EM SSD draw during sustained all-day operation?

The drive uses the SAS 12Gb/s interface and a 3.5-inch form factor, so power draw is governed by the server backplane and workload rather than a single published figure.

What server backplane and cabling must already be in place for this SAS 12Gb/s hot-plug drive to function?

A 3.5-inch hot-plug SAS backplane running at 12Gb/s with compatible power and signal cables is required; the drive is validated for the HP ProLiant XL190r Gen9 Server.

Will this 400GB 12G SAS EM SSD work in an older ProLiant that only supports 6Gb/s SAS backplanes?

The drive negotiates down to 6Gb/s on legacy backplanes, but full 12Gb/s throughput and hot-plug behaviour need a 12Gb/s SAS controller and backplane.
