One of my site currently have 4 ESX host (all blade servers) and 1 DS4700 storage.
The 2 ESX host server (HS21) are installed with ESX3.5 and the other 2 (HS22) is installed with ESX4.1
All the servers are managed by a vcenter. and the LUN are mapped to a group in the DS manager.
Recently purchased HS23 is to replace the HS21 servers. The new server is installed with ESXi5.0 U3. I've created a new group in the DS storage and map a new lun.
I'm going to install a new vcenter to manage the new server. But my final result need to be the HS22 and HS23 to be managed by the new vcenter.
Is it better if I add the new host and new lun to the existing host group or add the existing lun and host to the new host group in the IBM DS storage?
