One thing I forgot to add, what happens if your single backup server
starts smoking and goes up in flames? :)

I only have 3 actual storage nodes in this environment, one because of
location, the other two are vcb servers at each location.  The rest are
dedicated storage nodes, each of them may backup a tb a night of data.

I'm trying to figure out why people have so many storage nodes...  10,
really?

I've got a fairly beefy backup environment, about 36TB on the weekends
and a
lot of boxes 100+.  And I'm doing this all on a single Sun T5240...
doesn't
even seem to be cracking a sweat.

Seems to me... any modern machine can handle:
    Atleast 6 1GB NIC's if not 2-4 10gb NIC's...  so that's 7-40gb/s
inbound...
    Atleast 2-4 dual ported 4gb HBA's... So that's 16gb/s outbound...

    And a modern 4x4 Intel server or a 100+ coolthread Sun server can
easily
move that much bandwidth...

    So why so many boxes?


Are all the storage nodes regional -- if so, I completely understand.
Are all these storage nodes for doing snapshot backups (which I've
learned
to despise and not value at all)?
Is it because you're using a Windows infrastructure?
Or Legacy?

Am I missing a boat somewhere?

Chester, can you explain why you have 10 storage nodes to solve my
curiosity?
