If add 4 disks of size 146 GB to a XP 1024 array and make it as a RAID 5 group, what would be the effective disk space available for use ?
I guess the answer is 3 * 146 GB = 438 GB, but wanted to confirm.
Solved! Go to Solution.

Re: RAID 5
CAP=(No of disks -1)* NNN GB per disk
3+1P (75% efficiency - for a 4 isk Array group) yields the best performance on the XP series although for "cerain applcaications" a 7+1P (87.5% efficiency 8 disk Array Group) is the most cost effective.
