Does it make sense....
-
to setup an iSCSI device to act as storage for a XenServer installation that would only be used to backup my VM's?
Even though the iSCSI target is
- out of warranty
- in a failed state
- has 4 disks only (for 4TB RAID5 Winchester - one drive failed)
- Would require me to setup another XenServer installation
-
If goal is "can I learn something doing this" - yes

That is not the goal.

Guess you've got my $0.02 then lol

@MattSpeller thank you.

Why do you want to do it
- What is the goal? -

If you don't care about the backups and don't care if you cannot restore, go for it.
If you want it as a working backup medium, alas try something else.
-
I don't see the point unless you are planning on replacing the failed drive.
Then it would be like any other NAS for backup. -

And that was my hesitation as well... if anything in the world happens to that iSCSI target...
-
@Dashrender There are no NAS functions at all. Only iSCSI capabilities on this unit.

Yep.
Now, how much data do you need to backup? And how long can you wait to restore the data?

Currently I'm backing up ~1TB of VM's, restoring would be "as soon as possible" in any event from which I need to restore.
-
What's the budget to do this?

My bad - you're right, this is SAN functionality, not NAS, but in this case, does it matter? it's just a dumping ground, though a bit more complex - Yeah it's probably not worth using.
I have the same issue with my ancient Drobo

"Using existing in office hours, and no additional hardware"
Meaning I can't replace the failed drive or purchase 4 higher capacity drives.

Even if the drive is replaced or the capacity is increased, what if the controller fails on the unit? or the PSU?
-
@Breffni-Potter I know this is rhetorical.
-
I would say it's not possible. If they insist, I'd keep the email of them signing off on your concerns. Then when restoring a failed VM takes the SAN over the brink and causes your restore to also fail, you'll have something to show them.
-
So everyone is in agreement with me.
it's not worth using it, and it's scrap metal at this point.
