We are changing our backup system and plan on using a Dell MD3260 as a primary disk storage device. It will house all backups from the local site as well as replicated data from the remote site. It will function as a primary stgpool only. The tape library that is also attached will eventually be phased out.
My question is, what recommendations does anyone have on setting up this device. I was thinking of creating several 2T virtual disks and then presenting them to the linux TSM server but I am not sure whether I want to put them all in a volume group or not since all of the striping is done on the back end of the device as all of the hard drives are in one giant dynamic disk pool. In each 2T disk, I was going to create 4 500G disk storage volumes. Or maybe 2 1T disk storage volumes. Because the disk storage volumes will be permanent and not eventually offloaded to tape, I want to make sure I set this up correctly. Any suggestions for best performance? Ext3? Ext2? Thanks.
