DL380 G9 with P440ar maximum number of drive in 1x RAID 6 group

DL380 G9 with P440ar maximum number of drive in 1x RAID 6 group

I will consider to order one DL380 Gen9 with HP Smart Array P440ar (26x 1.2T )


front 24 drive

rear 2 drive for OS


my questions is Smart Array P440ar support below configuration or not


23x drive RAID 6 group

1x drive hot spare

2x drive RAID 1 group forOS


If support, any limitation of logical drive under this RAID 6 group ?

I need to create 3 x logical drive under it


I think this hot spare drive for this RAID 6 without any problem, how about it can recover OS mirror if rear drive failure






Re: DL380 G9 with P440ar maximum number of drive in 1x RAID 6 group



Refer to P440ar QuickSpecs here:



> The SA-P440ar Controller supports up to 26 physical drives with HP 12G SAS Expander card.
> Standard on the P440ar are RAID 6, RAID 60, RAID 1 ADM, Capacity Expansion, mirror split, recombine, and rollback in Online Mode, Drive Erase, Performance Optimization-Degraded Reads and Read Coalescing, Move/Delete any individual LUNS.

> Up to 64 logical drives supported.

> On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed automatically.


A SAS Expander Card is required to support the maximum drives on this server.



Going by the QuickSpecs, your questions should be answered, but I personally have not tested your required configuration.

Do talk to HP PreSales team.

Hello @EwingCWNg


Suman_1978 is correct in the information given, you can find the drive information on page 2 of the HP Smart Array P440ar Controller QuickSpecs, and you can find the RAID information on page 3 and 4 of the QuickSpecs.


You can purchase the HP 12Gb SAS Expander Card with Cables for DL380 Gen9 directly from the HP Small and Medium Business Store web site. 


I will be happy to connect you to the correct HP Presales agent for more information on the options of the HP ProLiant DL380 Gen9 server series.
