Hi Monte,

  I did one install with EMC DMX1000 disk with hardware mirroring used for 
a DSSU and I have to say I found performance wasn't great. Worse than LTO2 
performance but this was writing to a fairly small number of physical 
drives, though performance wasn't an issue so I didn't spend a lot of time 
tuning it,

                cheers Andy.

configurations


I wanted to get a feel for what type of disk storage is being used out 
there for disk based backups.  I am specifically looking for SAN attached 
storage ATA, SATA and what type of RAID is used and how it is performing 
overall.   The NBU 6.0 tuning guide shows RAID-5 but I am wondering if 
anyone is using RAID-10 or others.
 
Thanks, Monte
