Actually, it seems that this is more than sufficient:
iozone -m -t 8 -T -r 128k -o -s 4G
Good news, cuz I kicked off the first test earlier today, and it seems like
it will run till Wednesday. ;-) The first run, on a single disk, took 6.5
hrs, and I have it configured to repeat ... 2-way mirror, 3-way mirror,
4-way mirror, 5-way mirror, raidz 5 disks, raidz 6 disks, raidz2 6 disks,
stripe of 2 mirrors, stripe of 3 mirrors ...
I'll go stop it, and change to 4G. Maybe it'll be done tomorrow. ;-)
Probably even 2G is plenty since that gives 16GB of total file data.
Keep in mind that with file data much larger than memory, these
benchmarks are testing the hardware more than they are testing
Solaris. If you wanted to test Solaris, then you would intentionally
give it enough memory to work with since that is now it is expected to
be used.
The performance of Solaris when it is given enough memory to do
reasonable caching is astounding.
