I’ve a Windows 2003 server (32-bit) running BackupExec 2010 named BKSERVER.  I’ve installed  Navi Windows Host Agent v6.28..22.0.35 on this server and the server has an HBA zoned in Cisco 9124e to see the EMC CLARiiON CX4-240 SAN (SPA and SPB).

From the EMC SAN, it shows that the HBA is logged in and registered.  On this SAN, I currently have 2 Storage Groups (VMWare and NG).

VMWare Storage Group contains 6 VMware ESX Hosts v3.5 Update 5 and NG Storage Group contains 2 Windows 2008 64-bit servers.

I would like to have the BKSERVER to be able to see and read all LUNs so that I can backup the Virtual Machines (*.vmdk files) more efficiently by adding the server to both Storage Groups (without adding the server to the Storage Groups, I do not see the BKSERVER server listed under the Storage tab in the EMC SAN, although the BKSERVER server is currentlylisted under the Hosts tab.)

I do not plan to write any data to the LUNs that all servers in both Storage Groups can see and access from the BKSERVER server

Is there any potential problem that you can see if I add the Windows 2003 server to the existing Storage Groups – VMWare Farm and NG?

My thinking is that if the BKSERVER server has a direct connection to the SAN, then all virtual machine backup traffic should go through the fiber connection between them instead of going over the Ethernet side.

Thanks for your input
