RE: Advantages of Multiple NIC cards in AS/400

[Walden Leverich <walden@xxxxxxxxxxxxxxx>]

Bob,

For the most part, I don't think you're likely to overload the individual
board on the AS/400, you're more likely to overload the specific subnet. The
obvious exception to this would be if you have multiple subnets feeding into
a backbone and the AS/400 is connected to the backbone via a single card.
I'd suggest multiple cards in the AS/400 each serving a different subnet. If
you go to this setup, turn off IP routing so that your AS/400 doesn't waste
time routing IP packets from one subnet to the other, this is better left to
dedicated router hardware.

Subject: Advantages of Multiple NIC cards in AS/400


Greetings,
What would be the advantages/disadvantages of using multiple Network
Adapter cards in the AS/400 in an Ethernet (TCP/IP) environment?

A client is using a C/S application that stores large binary files on
the AS/400. There is concern of overloading the Adapter card as the
usage of the application increases. We are wondering if anyone has used
multiple cards, and how to "dynamically" balance the load? The AS/400
has plenty of capacity (average 30% CPU utilization), there is just this
mnagging concenr about the traffic load.

Any thoughts or comments?

Thanks,
Bob
