How do I zone my fabric and will this improve backup performance?
We have a qlogic 2/8q fabric switch that we use to connect 1 MSA1000, 6 Proliant servers and 1 MSL6030 Tape library with 1 Ultrium 4 Drive. All the servers have windows 2003 installed.
We use Arcserve Backup 11.5sp3 with SAN agents to perform the backups. This requires 1 server to be designated the Primary Arcserve Server and the
other 5 to be Arcserve Member Servers.
Each server currently backs up its local data as well as its presented storage on the SAN to the Tape Library. We've been told that our backups are taking too long.
The qlogic switch is currently unzoned with everything seeing everything else.
If I wanted to create zones on the switch in this scenario, is my only option to create 6 zones, each zone containing a single server, the SAN and the Tape Library?
(we are only using one port on each HBA)
Am I guaranteed an improvement in backup peformance after having zoned the switch?
Please let me know how I should zone the switch and give as much detail as possible as I have not done this before.
