Presenting datastore LUNs from multiple vsphere platforms to same VMware backup host
We have been running a Windows 2008 VMware Backup Host in NetBackup 7.5 successfully for some time. The Backup Host uses SAN transport and has datastore LUNs from a vSphere 5.5 instance mounted over FC. A new vSphere 6.0 instance has been introduced using iSCSI storage. Assuming I upgrade to 7.7 first to support vSphere 6.0, can I zone these datastore LUNs to the same VMware Backup Host and add the vCenter 6.0 credentials to NetBackup to enable VM backups for this instance too?
I would add dedicated NICs to the server for the iSCSI connectivity and for now lets assume the Backup Host's performance is not an issue.
It seems you have actually opened 3 questions: SAN transport over iSCSI, multiple vCenter datastores zoning, and multiple vCenters registration in NetBackup. But answer to all is yes, it is possible and supported.
