[comp.unix.sysv386] Exabyte and Multiple SCSI device performance

sl@van-bc.wimsey.bc.ca (Stuart Lynne) (04/03/91)

I'm looking at installing a SCSI based Exabyte to keep van-bc backed up. Two
questions which came to mind:

	1) Should we be adding a second SCSI controller
	2) Does the Exabyte support write/append

Currently we're running SCO UNIX with a 150MB tape and 3 SCSI hard disks on
an Adaptec 1540 controller. Should we add a second controller with the
Exabyte? If so should we put disks on one controller and both tapes on the
other? Or split both drives and tapes across both controllers?

With the Exabyte, can we leave a tape in it, and perform successive
incremental saves using the non-rewind device? This presumably would allow a
cron script to do incremental backup's automatically once or twice a day.

Any comments would be welcome. Thanks....

Hi Stuart - we like you connect via SLIP to another box
running 386 based unix and are looking for an automated
way to re-establish the connection should the line drop

Do you have any pointers or ideas on this?
