        We have two adapters on our 400 and on tcp/ip connections
originating from the 400, the OS does appear to be load balancing.  How it
does this, I don't know;  I never set any parameter for it and never found
one to set.  However, since each adapter card will have it's own IP address,
tcp/ip connections originating from the outside will not be load balanced.

Subject: Advantages of Multiple NIC cards in AS/400

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?
