David,
This is good to hear. I just ordered 288 GB of SSA disks for our HP3000.
Some folks at HP tried to scare me away from it, implying that diagnostics
didn't work, etc. When I asked for specific, technical information that
might dissuade me from the SSA purchase the silence was deafening.

Look at IBM's SSA for the HP3000. It is typically several HUNDRED
PERCENT faster, at about half the price. Hardware mirroring is in
beta now. All the usual features you would expect, including:
- hotswap
- multiple initator support (with limitations)
- RAID capability
- Works with HP's predictive & other diagnostics
- priced around 50 cents/MB.
- very high density .. almost a terabyte in a HP 19" rack
- no single point of failure (redundant paths, cables, power)
- add, delete, reconfigure, mount them to different systems without a
reboot!!! (requries 5.5)
yada yada yada
I know, I was the project leader on the team that ported it to the
HP3K I contracted Michael Hensely with Allegro to port the diagnostic
routine to MPE/iX ... So you know it was done right!
