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 : https://www.google.ca/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwids5e4qv_KAhWCWT4KHR7SCXsQFggcMAA&url=ftp%3A%2F%2Fftp.dell.com%2FManuals%2Fall-products%2Fesuprt_ser_stor_net%2Fesuprt_dell_adapters%2Fpoweredge-rc-h200_User%27s%2520Guide_en-us.pdf&usg=AFQjCNEYw-FZlmVPsvBUtB36Ofj_AxKrVw&sig2=8JlebN4zaNrAMqysXW1_vw "SAS, SATA or SSD physical disks cannot be used in the same virtual disk." – Bastien974 Feb 17 '16 at 17:34
