Re: [Networker] Upgrade Time... (7.4.4 to 7.5.1)

Hi
We also have some storage nodes scattered around in the datazone. Here
it's manly due to network issues. If I use a storage node with an
local autochanger/file device/whatever, I only have to push metadata
through the networker to the backup-server. Not all the client data.
So there's one reason for using storage nodes :)
Kind regards,
Jens

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?

I have two questions:
1) Do the networker server and all the storage nodes need to
run
the same version? I have over 10 storage nodes and didn't know
whether
or not I needed to upgrade all of them at the same time.
Yes.
2) Is there anything important I'm leaving out?
Most upgrade documents recommend you check client indexes and the
media
database before doing an upgrade
nsrck -L6
nsrim -vX
