RE: Advantages of Multiple NIC cards in AS/400

Bob,

We also have multiple NIC's (3) on our AS400.  We recently upgraded from
CISC to RISC.  The new box had a 10/100 built in and we had previously two
10/10's.  Our plan was to move everything to the 10/100, but found that
isolating our network printers on the 10/10's helps throughput and also
isolates our printer problems within the network and coming through the
Firewall.

Every little bit helps.

Bob,

 The majority of the systems we install these days are dual homed. We base
this on the following
advantages: 1) Additional Capacity, 2) Redundancy in case of failure (Of the
cable, the Card, the
TCP/IP stack.  The newer cards are cheap enough that this is usually a good
enough argument.

 As to load balancing we have done some of this manually but have not looked
into any automatic
process.
