So you're building your LUNs RAID5 4+1, then presenting multiple LUNs to =
the server and striping across them with your VM, or what?
=20
or is each DSSU only the size of 4 disks.

        We are just starting to set up DSU storage and have completed some =
extensive performance tests.  So far, we have found RAID5 4+1 works best =
with our file system (small files) backups and RAID3 4+1 works best with =
our database and raw backups.  There is still some testing going on as =
far as buffer settings, we are between 256k and 512K buffer settings and =
are still not sure which is going to work out best for us.  These tests =
have all just been done in a test environment, we won't know if we have =
to tweak anything for production for another month or so.

        Hi Monte,=20
=09
          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,=20

        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.=20
