Can I expand Raid 1 array capacity by upgrading hard drives on Dell Perc H700 Card?
Posted on 2012-09-06
Bit of a newbie when it comes to RAID configurations in servers and wanted to ask a question. I'm about to buy a Dell rackmount server with a Perc H700 raid card and 2 x 2TB Hard Drives configured in Raid 1 to give redundancy. My question is, if in the future we want to go to 2 x 3TB drives will I be able to replace the first drive with a larger one, rebuild then replace the second drive or would I have to image the whole thing and start again?
I kind of want to stick to Raid 1 as it gives me better recovery options should one drive fail but I also like the idea of being able to dynamically expand the storage with bigger drives.
Any thoughts would be gratefully received.
