Netbackup + VPLEX Integration experience

Hi all, I would like to know i f someone has any experience integrating Netbackup backups and VPLEX for VMWARE. As I haven´t found anything. VPLEX is a kind of storage virtualization, I am wonder...

I marked Marianne´s post as solution, and I still agree about that because it´s right that NBU backup host needs to be zoned to the SAN datastores and it clarified me a lot, but I still have a doubt and I´ll try to explain it better. Maybe someone could give me more light on this...

Actually our infrastructure consists on 2 storage subsystems replicated, which makes all data inside them consistent.

In the future we are thinking about testing some extended cluster solutions for Vmware (VMotion) and VPLEX is one of them, requiring to disable the subsystems replication (VPLEX assures the data consistency between them).

VPLEX, as a storage virtualizator, adds an extra layer between VMware and the datastores, presenting the datastores as a virtual volume for VmWare machines. It wouldn´t affect the virtual machines as they think they´re still accessing the storage.

I wonder if Vplex could lead to inconsitencies  in our backup copies because the LUN in the storage subsystem  and the "virtual datastore" that VPLEX presents to VMWare are not exactly the same. What will happen if our backup copy is done while some data is still in any kind of VPLEX cache and not properly saved in the storage subsystem?

 

Sorry for the long post.
