We've using Clariion Cx300 with ATA drives for disk
staging and performance is awful; seems to deteriorate over time.
Currently RAID5 LUNs (tried RAID3 which had similar performance and even tested
RAID0 which wasn't noticeably better). I'm assuming the performance issue
is that with lots of different types of backups going to the array, we're making
them jump all over the place, but haven't really found a way of improving
it.
Actually we have some
quite large (2TB+) Oracle Test/Trng databases using ATA drives in a Clariion
CX700 arrays and get decent performance out of those. Of course that
is hardware RAID. Not sure what the SUN Thumper
uses.
The database on NBU is
relatively small by comparison though at the moment we do still have ours on EMC
Symmetrix (DMX3) but that is more for the warm fuzzy we get from Symmetrix
reliability.

Just as an aside, how many people are building Master

The master server is one big flat-file
database. Why would you want it on SATA? I don't imagine that many
database operations are going to any fun at all...
You could, on the
other hand, put a DSSU or DSU on your master on SATA but that would be providing
media server functionality, not master server functionality. I'd be okay
with doing that (and am doing it here).
