HPE MSA 2052 "virtual storage?"
Need some clarify from what I'm reading in the speed test documentation. It seems data is stored across all disk groups in a virtual pool. Meaning, If I built one RAID 1 disk group, and another RAID 5 disk group with the intention of splitting SQL transaction logs from the database, this would give me no benefit as I don't have control where the files are actually stored on the hardware? showbox

Re: HPE MSA 2052 "virtual storage?"
Correct, unless you configure your separate storage in the 2 Pools. Pool A is all RAID 1 and Pool B is all RAID 5/6 (RAID 6 would be recommended unless using all SSDs). You could also use Tier Affinity on the Volumes to 'suggest' to the system to use a specific tier, would not help if both your RAID 1 and RAID 5/6 were the same media type.
Look at this tech brief for more indepth understanding of MSA virtual concepts: https://www.hpe.com/psnow/doc/a00087404enw
