Dell PERC 6/i configuration SAS/SATA

  • 772

What limitations are there to the configuration of SAS/SATA drives on a PERC 6/i raid controller. Can I have 2 virtual disks - RAID 1 SAS and RAID 5 SATA, or the other way around? Does it matter that the first VD is SAS/SATA or is it not important? What do Dell recommend?

Can't seem to find the technical guide...

    Couldn't locate drive mixing in my brief search of the manual, but I am fairly certain you can mix drive types in the server/controller (SAS/SATA/SSD). You cannot mix drive types in the VDs (can't have a RAID 1 with a SAS and a SATA drive). It's been a few years , but I've used a MD 3000 before which was pre-PERC 6 and you could mix drive types in that enclosure (SAS/SATA) so I assume you can do the same with a later PERC. It shouldn't matter what your first VD drive type is either. I would typically make a RAID 1 SAS for the OS, then whatever else is required afterwards for the server.

  2. you can mix drive types, though for some SATA disks you will need an interposer card. You cannot mix disk types within the same VD of course. ordering does not matter. Of course you need drives supported by Dell (others might or might not work, but you know how brand vendors are about this)
