I have a Dell Poweredge R410 with Perc H200 controller.

I would like to upgrade my 15k RPM arrays with SSD. Both disks are SAS 6Gbps.

  • Will it work if I remove 1 of the 2 disks, replace by the SSD, wait for sync then replace the other one ?

  • HDD=600GB, SSD=800GB or 400GB. If the HDD only has 100GB used, will the controller by smart enough and allow the sync with a 400GB SDD ?

You cannot mix drive types in the same array group on PERC/LSI/HP hardware RAID controllers.

This also applies to mixing SATA, SAS and SSD.

PERC manual:

"Mixing SAS and SATA drives within a virtual disk is not supported. Also, mixing hard drives and SSDs within a virtual disk is not supported."

  • You can't mix SATA and SAS but if both are SAS then it should work. You definately can't use a smaller drive though. – JamesRyan Feb 17 '16 at 17:17

    So... you say it should work, @ewwhite says it doesn't. – Bastien974 Feb 17 '16 at 17:25

    Thanks. From the H200 manual : google.ca/… "SAS, SATA or SSD physical disks cannot be used in the same virtual disk." – Bastien974 Feb 17 '16 at 17:34
