The PERC 710P supports both SAS and SATA disks. I have a single RAID1 set and would like to add a RAID5 set built out of SATA disks for archival use, but I cannot confirm that a configuration like that is possible. Citations requested if possible.

    This question appears to be off-topic because it is about reading the vendor documentation – HBruijn Jun 12 '14 at 14:15
  • Why not just call Dell support and ask them? – Rex Jun 12 '14 at 14:40
  • The documentation only claims to 'support' them. – Jeff Sacksteder Jun 12 '14 at 15:45

It's possible as long as the drives are not mixed together. In addition, I would reccomend using nearline SAS drives instead of SATA for stability reasons.

  • +1 for NLSAS. Not much more expensive but less likely to cause controller issues. – Grant Jun 12 '14 at 15:21
  • To clarify, do you mean mixed on a controller or mixed in one array? Can I do a raid1 sas and a raid5 nlsas on the same controller? – Jeff Sacksteder Jun 12 '14 at 15:41
  • Mixed in one array. The controller won't allow you to do it. – ewwhite Jun 12 '14 at 15:42

Mixed SAS/SATA drives cannot be combined in a single common virtual disk or RAID set, but you can create separate VDs with various types (RAID1 on SAS, and a separate RAID5 on SATA).

Source: Documentation (below), and personal experience in Dell Storage Support.

H710 User's Guide

Page 9: "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."

I was able to accomplish something similar what it sounds like you're wanting about a week ago; Existing VD on SATA disks, new SAS drives added to a server, and the H710 allows to create a 2nd separate VD on the added drives.
