HPE DL380 Gen9 Hybrid SAS SFF WSSD Premium Solution

Configuration guidelines

  • The P840/P840ar controller is the most performant Storage Controller with 16 PCIe lanes, supporting up to 16 drives. It is your best choice for achieving maximum storage spaces direct I/O performance without the use of a SAS expander.
  • Do NOT configure a node using two storage controllers with the same model name. Invalid storage controller configurations are:
  • Configuring an H240ar in addition to an H240
  • Configuring a P840ar in addition to a P840
  • Configuring a P440ar in addition to a P440
  • Use of alternative size Cache SSDs and Capacity HDDs is supported.
  • The Cache must be configured with 2 or more SAS SSDs with a size greater than or equal to 400 GB per drive.
  • The Capacity must be configured with 4 to 16 SAS HDDs with a size greater than 300 GB per drive.
  • See HPE ProLiant DL380 Gen9 QuickSpecs for alternative Drive Options.
