Two Network Cards on Active Server 2000 2.1 / 1.1 versus 1.1 / 1.2

Query setup as subnets versus same subnet with different TCP/IP addresses in
network speed.

Is it better to divide a network with same 25 workstations into two subnets
with a server with two network cards
with different addressess say subnets 192.168.1.1 for one card and
192.168.2.1 for the other for two subnets ?

Or would having all workstations on same subnet with net work cards set at
say 192.168.1.1 and 192.168.1.2 on the active server be equivalent ?

Or would there not be a lot in it ?

Depends from what point of view. From a traffic perspective setting up 2
subnets essentially turns the server into a router and therefore dissects
the network in 2. Traffic on subnet 1 stays on subnet 1 unless it needs to
be routed. IP traffic therefore becomes more efficient, specially when
netbios broadcasting is considered (udp doesn't cross a router). The server,
however, needs to work to route the tcp pacquets through a routing table.
But heck, that's the perfect job for a multihomed server.

If you choose to operate a single subnet throughout, the second NIC becomes
redundant unless you wish to provide load balancing, in which case you
shouldn't physically dissect the network.

The point here is whether or not you wish the server to handle packets
passing through. It's not logical to seperate the same subnet physically in
two sections. You either place both NICs in the same physical and logical
subnet or you subnet the network.
