4173.0. "TCP/IP load balancing with NT-Clients" by COL01::SENSCHE () Tue Feb 25 1997 10:08
Hello all,
a customer has two-node DSSI-Cluster, running PW V5.0D ECO3,
VMS 6.2-1H3 and UCX V4.0 ECO2.
He is migrating all his PW Remote Boot Clients to NT 3.51 WS.
They continue to use Shares off the PW-Cluster for the User Data.
There is a problem with Load Balancing in the Cluster. 99% of
the NT-Clients do not connect to the least loaded Clustermember.
The machines involved are:
BYBW PW-Cluster-Alias 192.109.161.244
DXCW19 Clustermember 192.109.161.017
DXCW1A Clustermember 192.109.161.108
DBY001 NT-Client 192.109.161.004
MASTERBDC1_BYBO WINS-Server 192.109.161.245
I can't provide an Iris Trace, as the Customer Site is in Berlin
and i'm sitting in the Customer's HQ in Bonn. I used the Microsoft
Network Monitor (of SMS) and got the following:
- Client asks his WINS-Server for the IP-Address of the PW-Cluster-
Alias and gets it back.
- Client makes an ARP request. The impersonator of the IP-Alias
answers the ARP request.
Any hints ?
Volker
I append the trace and the output of NBSHOW KNB from both Cluster-
members

| Voker,
Um, the true PATHWORKS cluster alias does NOT have it's own IP address.
You're either using the UCX cluster alias (which might be the same name
as the PATHWORKS cluster alias) or you're using the UCX metric server
functionality.
In any case, you're not using the PATHWORKS load balancing mechanism
(which only applies when a new client session is established using a
NETBIOS findname broadcast which the least-loaded PATHWORKS server will
be responding to).
WINS NETBIOS name resolution doesn't provide any load balancing that
I'm know of (maybe round robin at best). The UCX cluster alias (the
cluster "impersonator") isn't a load balancing mechanism either. The
UCX metric server CAN be used to provide true load balancing and would
do so for all IP applications/services to the cluster, not just
PATHWORKS; it would also be available across a WAN. It uses DNS, not
NETBIOS.
HTH,
Paul

| So, how must things be set up, to get Loadbalancing for IP-only
NT-Clients, if possible ?

| If they'll all be in the same subnet as the PATHWORKS cluster, you can
use the PATHWORKS cluster alias for load balancing. Otherwise, I guess
you're left with the UCX Metric Server (which I've never set up; ask in
LASSIE::UCX conference).
On the other hand, other IP vendor's stacks that work with PATHWORKS v5
server may offer other load balancing technology that's more
appropriate for the customer's environment.
