disk configuration

[Ken Leonard]

We are attempting to specify a multi-PClone system using *NIX (probably SCO
or ISC, U*** not XE***) and are quandarized on disk configuration.
--
A key issue is that at least one machine in the net will be running *DOS
much of the time with PC/NFS sharing files _both_ways_.
--
At least one machine will have a cartridge-tape drive for backup.
--
We need to run essentially the same disk/tape configuration of types, not
sizes, in all of the machines.
--
Comments on the following will be appreciated:
-
Using SCSI for tape (in CPUs with tape) and ESDI for disk (in all CPUs), or
using SCSI for tape and disk (in all CPUs.)
-
Having more than one disk on a CPU with a tape, or having more than two
disks on a CPU with or without a tape.
-
Having *DOS/*NIX-compatible partition table on all disks, even if only *DOS
or *NIX partitions on some drives.
-
Using a common, *DOS-based, partitioning/lowlevelformatting/badtrackmarking
utility since it's a lot easier to floppyboot *DOS to do fixups/changes.
We like SPEEDSTOR on our present *DOS-only CPUs.
-
Using a *DOS-based lowlevelbackup (per drive or partition) utility, so it
can be floppybooted.
-
What have we overlooked?
