We are currently using the VMWare integration of DP to backup our VM's from 3PAR datastores. We would like to setup the ZDB integration for VMWare with 3PAR, but the documentation (GRE admin guide and GRE integration guide) are not clear at all. Can somebody give me more detailed infromtation on below questions:
1) It seems a dedicated VMWare ESXi mount host is needed. Is this also needed when you only want to put the backups on tape (in this case StoreOnce catalyst)? In other words, why is this dedicated ESXi mount host needed if you don't want to use IR or GRE with 3PAR ZDB protection for VMWare?
2) According the existing documentation replica's (snapshots of the VMWare datastores) will be presented to the ESXi mount host. How can we use the SAN transport protocol over FC, if the replica's are presented to the ESXi mount host?
3) Besides the VMWare ESXi mount host, it seems a Linux mount host is needed if you want to use GRE in combination with snapshots residing on the 3PAR, correct? I presume I can also perform GRE without this Linux mount host, but then it will be non-cashed GRE and you can use a windows host? Am I correct?
