You really should be using RAID6 or RAID10 rather than RAID5 as it is even more redundant (i.e. can survive 2 disks failures).<br>

And you shouldn't be using RAID5 or RAID6 at all if your drives are 750-1000GB or larger.<br>

Our disks are 600Gb.<br>

Is there any advantage to using the PERC to create 2 virtual disks from the RAID array? Or should I partition it in the OS? Right now, the PERC is configured with one virtual disk for the operating system and another for the mail. But I could make one big virtual disk out of the 5 physical disks which would show up as a 2Tb /dev/sda. Then I could use the installer to partition it.<br>
to partition it.<br></blockquote></div><br><br></div><div class="gmail_extra">Do you currently have disks fully dedicated to each virtual disk, or are you using a slice of each disk to make them? If you're dedicating full disks, I'd switch to using 1 big RAID, then partition it and use LVM for flexibility. You might want to think about sacrificing some space and go to RAID6 or RAID10 if you can. With a RAID10 you'd get about 1.2TB of space, a hot spare, and a performance increase.<br>
