All of our recent NetBackup server purchases have been T5120s. They run
just fine. We aggregate the four GigE NICs via dladm(1M) for extra
bandwidth (round-robin at the L4 layer). Plug in dual HBAs and you'll have
plenty of bandwidth both in and out.

The CPU comes with on-die dual 10 GigE if you really want network
bandwidth, but you'll be taking up a PCIe slot for each interface. So if
you want many HBAs (and not just one dual-ported HBA) you many need a
T5220 which has more PCIe slots.

Personally I think the T-series would be better than the M-series, as you
want parallelism for multiple I/O streams, and that's what the CoolThreads
servers were designed to handle: parallelism. AFAIK, the M-series is more
about single-thread performance (we have a few for some of our Oracle DB
stuff).
