OK, if you have two nics on server A with crossover cables to two nics on server b, it will be no different than if they were connected with a hub, bridge or switch. They each need their own small IP address nets. Then, why should IPMP care what the network fabric is?

I am not personally experienced with crossover cables. I heard that it can be hard to get them to behave if one server is powered off, but perhaps some nic firmware has stepped up to this. It seems like a frequently overlooked inexpensive and fast network fabric, with no collisions and in full duplex with not much length limitation. NICs are cheap, and wire is far cheaper than gigabit switches! You might run out of slots after a while. There is much need for this sort of bandwidth with high performance SAN and RDBMS client-server configurations.

ipx_cmd

IPX_CMD(8)						      System Manager's Manual							IPX_CMD(8)

NAME

       ipx_cmd - bridge between Novell's SCMD driver and local IPX network

SYNOPSIS

       ipx_cmd -A server name [ -l local interface name ]

DESCRIPTION

       ipx_cmd moves packets from tapN to server and vice versa.  It is something like IPX Tunnel, but it uses Novell Netware 5 server Compatibil-
       ity Mode Driver (AKA Migration Agent) on the other end of wire. You must first configure your kernel tapN device with IPX EthernetII  frame
       and with network number set up on server (you can use kernel autodetection).

OPTIONS

       -A server name
	      This is IP name of compatibility mode server. You can use DNS name or dotted quad to specify server address.

       -l local interface name
	      This allows you to specify, which of your IP addresses should be used as IP address of client side of CMD driver. You must configure
	      your tapN device with hardware address 7E:01:AA:BB:CC:DD, where AA:BB:CC:DD is your IP address in hexa.

EXAMPLE

       If you are on server platan.vc.cvut.cz (147.32.240.81) and your migration agent runs on server boris.vc.cvut.cz,  you  can  configure  your
       system with:

	  insmod ethertap
	  ifconfig tap0 hw ether 7E:01:93:20:F0:51 up
	  ipx_interface add -p tap0 EtherII
	  ipx_cmd -A boris.vc.cvut.cz -l 147.32.240.81 &

BUGS

       This program was written to satisfy my own needs and should be really improved.	At least it should configure tap interface itself.
