Backup Performance and Fibre Channel Zoning
Posted on 2013-01-30
We recently acquired an EMC VNX5300 and a FC Tape Library.
The original zoning configuration was not following EMC’s best practice for single HBA zoning so I went ahead and created new zones.
Before the change, one of my backup jobs which used to take 11+ hours went down to 5+ but after creating the new zones my backup jobs is taking again 11+ hours to complete.
To accomplish the backup, I am using a windows 2003 server with Arcserve R16 on it. This server, BackupServer1 has a dual 8Gb HBA and connects to both FC switches.
The backup job backs up a LUN that it is attached to a Solaris server. The Solaris server uses a single HBA 4Gb connected to SANSwitch1.
The VNX_SPA, VNX_SPB are the storage processors for the VNX 5300.
The tape library is an (Overland) IBM 3573 FC with dual LTO6 drives. I have one drive attached to SANSwitch1 and the other attached to SANSwitch2.
The switches are EMC (Brocade) DS-300B 8Gb FC.
I am obviously not a storage person and I just started learning about Fibre Fabric and Zoning.
Does my new zoning configuration make sense?
Could it be improve?
Is anything on the way is configured causing my backup issue?
I know there are other things on the variable such as the backup server itself, backup software agent and the library that could be the culprit, but I need to start somewhere.
Thanks in advance for your help.
