Very Computer

We have an HP 9000 712/80 which already has a few external disks/tape
drives attached to it, but we have a need for yet another disk.  The
SCSI-II chain currenty looks like this:

ID#     Device
---     ------
3       4mm tape drive
4       1 GB HP drive   (A2657A)   (all drives single-ended SCSI-II)
5       2 GB HP drive   (A2656A)
6       2 GB HP drive   (A2656A)

The question is: can we add another (1 GB) HP disk as SCSI-ID# 7 ?
If so, will the system's I/O performance deteriorate drastically?

If anybody has a scenario similar to this, I'd love to compare notes.

Thanks!

As for whether it'll impact performance or not, who knows...depends on
how what your disk pattern is like.  A scsi-2-se is 10Mb/s...given the
number of disks you have, you might hit that limit if you do some large
accesses.  Depending on cost considerations, you might bite the bullet
and get a singel 4Gb barracuda or something.  It'll help in future expansion
and you might be able to move some data from your other disks onto this one.
Of course, reducing the number of spindles might not be a good idea but
it might depending on again, your access pattern.
