We use the Advanced Client add-on for 5.1 (another licence - name may be
changed in v6.0).  One of our media servers is configured to see the
same SAN disks as the servers which we want to back up.  Throughput
seems to be very roughly twice what we would get over the 1 GB LAN.
Nothing is mounted to the media server but the Advanced Client client
effectively passes over the network to the media server a list of
locations of blocks to back up, which the media server then sources
directly from the SAN.

There are a lot of different options in Advanced Client and dependencies
over what volume management, switches etc. etc. you can use, so read up
on it first.  It's also might be an issue that all the SAN disks are
visible from multiple places.  There are also differences in the way
RMAN backups work using Advanced Client, which advise thorough testing.
Works quite well for us though.

cheers, Phil

Subject: [Veritas-bu] Is this possible ....


Back in January, I replace my old SCSI attached tape library. I now have

an Overland Storage NEO8000 with 6 drives, plus a REO9000 which is 
sliced into multiple 1TB partitions which I have mounted on my media 
server (Sun Microsystems Ultra Enterprise 450 running Solaris 8 and 
NetBackup 5.1mp5) to use as DSSU's.

In the next two months, I will be switching from systems with direct 
attached drives, (which I backup over the network) to a full SAN.

Do I continue as I have? Backing up the clients over the (1000Base-T) 
network?

Can the DSSU partition be shared between the client and the media 
server, and client write directly to the DSSU, and the media server 
write it to tape?

Can the media server mount the clients (SAN) volume, and back it up to 
the DSSU directly.  (Although I see this option fought with backup 
management issues.)
