Dave,
I am no NB expert, so bear with me...
If I have a class(Class1) with say 4 clients. I direct that class to a "Storage
Unit" (SU1) for backup. That "Storage Unit" is made up of 2 media servers
sharing a common robot (TLD). Can I define a second storage unit(SU2), built
using different names/IPs that refernce those same two media servers? This
would allow me to define another class of clients(Class2) and direct them to a
SU2 and that second virtual storage unit would really just reference the same 2
media servers by different IP addresses. Would this result in the clients in
the second class sending their backups to the specific interfaces that use the
second set of addresses, versus the IP/NICs defined for use by the first
storage unit?
REQUIRED_INTERFACE restricts use from a NB node on packets going out, correct.
I am actually trying to get clients to use more than 1 interface on the media
servers so I do not bottleneck on one 100Mbps interface. I have 8 DLT7000
drives. I cannot push more than 80MB/s thru 1 net interface in a perfect world.
I know I will need to keep multiple net interfaces fed client data to keep the
8 DLT drives running near full capacity, right? And I am not in a position to
trunk.
