Use the maximum of 8 luns, thus accounting for 16 of 20 drives.

You could then configure at least 2 of the remaining 4 as hot spares. (If
you can configure all 4 as hot spares, go ahead.)

Also, it's best to utilize 2 SPU's and 2 controllers on the host and share
the luns among the SPU's.

You should have a max. of 64kb of memory on each SPU and configure them as
40kb for write cache, the balance for read cache.

The configured buffer size should be 4kb - which coincides very nicely with
the MPE/XL page size.

Love those mod 20's. They rock - figuratively, of course.
