I have SuperTrack EX8650 + 2*1 Tb SAS SEAGATE ST1000NM0023 + 2*2 Tb SAS Hitachi HUS723020ALS.

If i create disk array with 4 disks, i have array total capacity is 3.63 Tb, but disk total capacity is 5.48!

I need to create raid10 (raid1 with 2*1Tb + raid1 with 2*2 Tb).....

I can create 2 raid1 of this disks and it's work as 2 logical drive, but i want 1 logical disk.

Where is my wrong step?

p.s. Sorry for my poor English....

Thak's Richard!

So, all disk in "disk array" need to be a same size. Or EX8650 use smallest disk capacity in "drive in array" to build logical drive. OK!

Hi Vadim,

A Logical Drive will only use the capacity of the smallest drive used, so your 2TB drives will only be 1TB. That gives you 4*1TB.
