I'm looking into methods for HSM for my company.
One of the requirements I have is that restores must use the maximum speed we
can achieve.
I have looked at several TSM pages, but couldn't find something that explicitly
explains how parallel restores (the NQR option) are going to be performed.
My specific question is: Do all copies have to go over the server or can they
go over different paths?
For example:
2 files (F1,F2) are to be restored to two different primary systems (P1,P2)
from 2 different secondary storage systems (S1,S2). Does TSM support a physical
connection like the one shown bellow in a) or does it have to be a connection
such as the one shown in b)
a)
P1 <----- F1 ------ S1
P2 <----- F2 ------ S2
b)
P1 <--F1---\ /---F1---- S1
----- Server ------
P2 <--F2---/ \---F2---- S2
