Re: Setting up storage Array for ASM

Thanks Leyi. We have reserved 2 disks for hotspare already and usable we
have is 22 disks.

Is the 5 x 1G luns is for placing ocr and voting in high redundancy instead
of normal one.

To answer Steve, the storage is emc, cx series.

To answer Goran, We are designing this system to handle 1000 to 1500 IOPS.
