All,
HP-UX
calls their product "Auto Port Aggregation" (product number J4240AA).
It is a separately licensed product and is priced on a sliding scale,
depending upon the size of the computer it will operate on. HP claims
to be able to configure up to 50 aggregates per system. (Product
Brief: http://www.hp.com/products1/serverconnectivity/adapters/apa_prodbrief.html)
This
is the same as what Solaris call Trunking, though they support up to 8
links trunked into one logical IP address. Solaris 10 provides this
as part of the OS. Earlier versions charge for the software.
This
function is referred to as teaming, trunking, link aggregation, etc...
It is important to note that you must work closely with your IP Networking
Team. The ethernet switch ports to which you connect the multiple
physical interfaces you are trunking/aggregating must be configured to
recognize this. Cisco refers to this as "trunk groups".
Extreme Networks refers to trunking.
Make
sure the network switches your servers connect to can accomodate this type
of trunking, and that your IP Networking staff
can provide this service.

If you can figure out how to
do THAT, it would certainly be preferable to the NBU method.

My knowledge of HP-UX is limited,
but can you bind the interfaces (assuming they are on the same subnet?)
You could give both interfaces the same IP and have the switch "load
balance" the connections for you. I've successfully done this
on Solaris, Linux and Windows. I would assume HP-UX has something
similar.

Subject: [Veritas-bu] How to use different network interfaces
First off, NBU 6.0MP5, HP-UX.
I have a master/media server with an STK
L180 library and an Scalar24 library. The L180 is used for “normal” backups.
The Scalar24 (which has only 2 LTO-3 drives) was added as part of a special
project to migrate several clients to a different location. Basically backup
those clients, send the tapes to new location and restore the data.
In an effort to increase the data through-put,
I added 2 additional GB network connections. So now I have the following
interfaces:
Jac01.x.x.x Gigabit (original interface
for non migrating clients)
Jac01v1.x.x.x Gigabit
Jac01v2.x.x.x Gigabit
How can I best configure NBU to have as much
data as possible stream to the 2 LTO-3 drives in order to speed up the
backups? I know I could create an STU on each interface and set the policies
to use them, but that would seem to just make the jobs wait as other jobs
tie up the drives. What about using the “specified network interface”
for the clients? If I do that, how can I verify that the data is actually
moving on the new interfaces instead of the original?
Help?
Thank You,
