RAID-5 may be poor for some database loads, but it's perfectl
I have now downloaded zilstat.ksh and this is the sort of loading it
reports with my StorageTek 2540 while running the initial writer part
of the benchmark:
% ./zilstat.ksh -p Sun_2540 -l 30 10

I guess one question I'd add is: The "ops" numbers seem pretty small.
Is it possible to give enough spindles to a pool to handle that many

at some point, but are we at that point?
