Guest Flash3200 Posted January 11, 2008 Posted January 11, 2008 I realize this isn't necessarily Microsoft related so if someone know of a better group please let me know. I figured though there still had to be users here who have input... Thanks I have an IBM DS300 iSCSI SAN that I'm trying to figure out the best set up and utilization for our File Server so I can max out our available space. We have 14 possible drives to use can perform either Raid 0,1,5,10,50. We have gone with 3 arrays (4 drives, 4 drives, 3 drives) of Raid 5 with 3 hot swaps, 1 per array. Anyone have any better suggestions? I'd like to go to using Raid 50 however, with IBM it seems it Parities out space when creating the Array and then again when I create each LUN. Raid 5 isn't bad on space because it doesn't do the parity until you go to create the LUN, but you never know exactly how much availabe space you truely have left. I've heard that Dell/EMC SANs will take all parity out first and then when you create the LUNs you will always know what space you have left. Any suggestions would be great. Thanks again.
