CampbellMC. The maximum logical drive size for any Raid level would be 2TB. So you wouldn't be able to configure that large of a single array. ftp://ftp.dell.com/Manuals/Common/dell-perc-4-di_User's%20Guide11_en-us.pdf
Hi, I'm thinking of buying some SCSI-SATA bridge devices to convert my scsi drives that are hooked up to a PERC 4e/Di/Si controller and then use much higher capacity SATA drives (unfortunatel,there's a particular reason why I'm not just buying a SAS/SATA controller which would be much more economical). If I used 2TB drives, it would then be around raw 16TB (with RAID 0). Does anyone know whether such a logical drive size is supported by the PERC? Cheers, Cam
