Yes, as Will figured out too, it is an SSA. (Thanks, Will. That allowed 
me to Google the right thing...) I don't know the model; this only has 
2G drives in it.

What I would like out of this is to do some performace comparisons using 
DiskSuite in Sol9. I'm going to set up various stripes, mirrors, RAIDs, 
etc. on the SSA to see if I missed something when I set up the D1000 I 
have in production.

The D1000 is attached to a 280R, and I am convinced that it is not 
living up to its potential. It runs Oracle databases and seems to be IO 
bound.

It'll also be interesting to see how the bonnie++ test results on the 
SSA compare with some tests I did a while back on Linux RAIDs and a few 
other things.
