Gill,
   This sounds like an interesting environment.  Could you share some of
the particulars such as what storage device is providing the LUN, what
server OS is using the LUN and what the general reason was for choosing
the LUN?
   Historical note - My first hard disk in my home PC was 20GB

Thank you,

Subject: [ADSM-L] why create a 12TB LUN

I'm guessing many of you will find this quite odd, I know I did, but I
had someone come to me and say they were going to ask for a 12TB LUN and
wanted to back it up. Without even mentioning the product they want to
use, obviously not TSM though, and I'm not even sure it would make
difference, how would you manage to get a 12TB LUN backed up daily. I
would expect it to be at least 75% full if not more, and even without
knowing what percentage of data changes on it, it would seem to me the
request seems strange. They're thinking of getting a VTL and backing up
through fiber direct, not across the network, but no idea which one or
what sort of throughput to expect.



Have any of you been approached with this sort of request and if so what
was your response? I'm sort of dumbfounded at this point since I've not
heard or seen this anywhere.

Thanks,
