Hi
as you have no performance license and with MSA2050 you can only configure virtual pools
this means you should configure a pool with the same disk drives. you have 18 drives of 1.2TB
so you can create two disk groups of 9 drives raid 5 in the same pool or leave one or more drives
for spare. the same you can do with the other drive type. as for the SSD drives you can use them in
a separate pool or use them as SSD Read Cache extension that does nor require a license.
Regards
Give a KUDO if this helps
