FWD disk configuration

We have Alpha 8200 servers with four PCI fast wide differential
scsi buses. We plan to put a string of FWD differntial Elite 9
disks on each bus with a pair of disks stripped as logical volumes
using advfs. Each pair of disks will be paired on two different buses
giving 17.5GB LV. The disks will be in external 8 bay Sigma Chaisis.

Can any body tell me what is the maximum number of peripherals/bus? 15?
15 devices per bus would give us 516 GB, 4*15*8.5.

Performance is not a mjor concern. The data is staged to disk, processed,
and then sits idle for a day while the results are examined.
If some one has something like this can you warn me of any problems.

Thanks,
