HPE

HPE 811216-B21 ML350 Gen9 2nd SAS Expander Card designed to extend internal storage connectivity for high-density SFF drive configurations and support up to 48 SFF drives when correctly configured.

OVERVIEW

  • The HPE ML350 Gen9 2nd SAS Expander Card, part number 811216-B21, is a storage expansion component for the HPE ProLiant ML350 Gen9 server. It is designed for configurations requiring a second SAS expander to increase internal drive connectivity.
  • HPE specifies that the 811216-B21 works with the ML350 Gen9 SAS Expander Kit (769635-B21) and an HPE Smart Array P840 controller as part of a properly configured high-density storage system. In the supported configuration, the ML350 Gen9 can accommodate up to 48 SFF drives. 

USE CASES

  • High-density server storage expansion — Adds a second SAS expansion path for supported ML350 Gen9 configurations.
  • 48-drive SFF configurations — Suitable for ML350 Gen9 systems configured for up to 48 SFF drives.
  • Enterprise storage upgrades — Helps organizations expand internal storage capacity without replacing the existing ML350 Gen9 platform.
