The PERC5 and PERC6 series will not be able to use drives over 2048GB. They can make virtual disks over that size, but they just cannot use physical disks of that size. Only the H300/700/800 and higher support physical disks of more than 2TB.
I have a MD1000 on a perc 5/e controller. It currently has 5 - 2TB SATA drives and I want to expand. Will it take a 3 or 4TB drive?  I see that option on a storage site but Dell itself does not sell them larger then 2TB.  I've been unable to find out if the perc 5/e can handle a drive that size. Regards,
MD1000 + Perc 5/e, drives larger then 2TB?
