SAN Media server on SPARC hosting Solaris 10 global zone

We have two SPARC T-series hosting Solaris 10 Global zones, each with around 10TB of data.

On NetBakcup 7.6 side, we have several 5220 Appliances connected to LAN and SAN fabric. However, as per the old design the backup data transport for SPARC local zones is happening over the LAN, which is sometimes painfully slow specially for full backups.

My questions are,

1) can these SPARC T-series hosts with Solaris 10 Global zones be turned into SAN Media servers? and what does it require? OR keep it simple and,

2) Configure the SPARC T-series Solaris Global Zone hosts as SAN client ?

Thanks for your help in advance.
