We have had trouble with mirroring, which has the result that mirrors got out of step. I want to write a checker that can be used on a running system, and would like to know if there is enough commonality in implementations to extend this to RAID (yes, I know that mirroring is also called RAID-1,...

All, I am looking for a way to replicate i/o to a disk array that simulates a current symmetrix dmx in our environment.

Hi, I am comparing SATA single drive performance with the SATA RAID 5 and RAID 0 performance (the RAID is built of 4 drives) and getting counter-intuitive results. Initially, my test was to copy 100 files 12MB each in size under Redhat 9 linux. When I copied from the disk to /dev/null...

Can anyone explain this? I've burnt some files in at least two sessions on an Imation DVD-R disk.
