Hi,
Can anyone tell me how many SAS connectors are there on the back plane for the 1-8 SFF SAS Internal Drive Cage for the Proliant DL580 G7 server? I want to buy different kinds of drives for the OS and data storage. Thanks for any information!
Solved! Go to Solution.

Re: DL580 G7 internal storage
Hi,
Watch this video about SAS backplane removal, I see that there are two SAS connectors and two Power connectors for the SAS Backplane.
Spare Part# SAS backplane, 591203-001
Hope this helps.
I work for HPE.

Re: DL580 G7 internal storage
Hi,
you don't need to split HDDs between controllers.
All 8 drives on one SmartArray can be configured with several RAID simultaneously
Mixing SAS and SATA drives within one RAID is impossible,
all other combination is allowed.
For example: 2xSAS HDD 15k/RAID 1 (System) , 3xSAS HDD 10k/RAID 5 (Data1), 3xSATA 7.2k/RAID 5 (Data2).
BR, Oleg.

Re: DL580 G7 internal storage
Hi,
Thanks for the info. Because I can't mixed SAS and SATA drives within one RAID, that's why I want to check to see if there are two connectors (two channels) to the RAID controller. If there are two channels, I will get 4xSAS HDD 15k/RAID 1 (System) and 4xSATA RAID 5 (Data). Can anyone confirm there are two channels/connectors? Thanks again.

SolutionLike Oleg said, no issue mixing SAS and SATA drives on the same controller or channel as long as each RAID set contains roughly similar drives. I've got a DL380G5 with P400 running 2xSAS in RAID1 and 6xSATA in RAID6 all divided between two channels. Shows that SAS and SATA drives can co-exist on the same channel as long as they belong to different RAID sets (volumes).
