Hi,

That is a good question, in addition there is also a CAP option, the CAP in
the expansion module holds 10 tapes.  Currently, I am not using any SL500s
with only the Slot Expansion Module.

I am running the same configuration you are or plan to.

SL500 (base)
SL500 (expansion module, with 2 or 4 drives)

The drives lost whether its 2 or 4 appears to be the same because the slot
is reserved in the drive expansion module.

To let you know, we have a few different configurations but:

The SL500s+expansion w/tape cap for ejections holds: 133 tapes
And in the newer model SL500+expansion w/tape holds: 144 tapes

Whether there are 2 or 4 drives in the expansion module it should not matter,
I could be wrong but if you check the back of a DEM there are four spots in
the back for drives, at least that's how ours were configured.

So if you had:

SL500: 50 slots
DEM1: ~133 slots (whether 1 2 3 or 4 drives)
DEM2: ~133 slots (whether 1 2 3 or 4 drives)
Total: 316 slots

You should contact your Oracle rep to confirm but that is what I have been
seeing lately.  I just checked one here with 3 drives in the DEM vs. one
with two drives and they are all similar, either 133 or 144 slots.

Justin.
