Expand 2-tier, one pool MSA 2052

[johnnoakes]

Hi.

Need to add more disk for more preformance to our MSA 2052.

Current setup: 2-tier, 1 pool only (A)

6 800GB SSD RAID6 (no spare) (HPE MSA 2052 SAN Dual Controller SFF Storage)

10 4TB MDL RAID6 + 2 spare (HPE MSA 2050 LFF disk enclosure)

Connected to 6 hosts with a total of 86 (mail, file, sql, web, everything) vm.

Should I go for 4 more SSD, total 10 or add enclosure with 10k SAS (raid6 or 10?) and create 3-tier?

10 disks is max in same tier on raid6 (power of 2)? I don´t beleve in raid5.

Pool B is saved for a later time with the other free half of main unit with ssd + mdl/10k enclosure

Adding more SSD drives will ofcourse increse performance of your system comapred to any other drive type.

You can also consider "Volume Tier Affinity" feature as well.
