FlexLM on an NT Cluster

Can FlexLM be run on an NT Cluster? I know that AdLM for A2000i wouldn't, but i'm not too sure about FlexLM. What about FlexLM on a Netware 5.1 server?
Thanks.

Not a definative answer but this is my best guess.

It depends....

Okay I don't know much about clusters (much pronounced as anything), but
here's the way that it works.

My understanding of a cluster server is that you have basically two separate
machines with a shared raid (usually 5) array between them so that if 1 set
of "hardware" fails, everything is transfered over to the other server (and
I'm just talking about what I know from NT4, 2k could be completely
different, and again I know nothing about clusters).

Here's the problem. The flex "auth" code is dependent upon the ethernet
address of the ethernet card on the server to which it is authorized. Now
my understand (which is possibly completely incorrect, and please correct me
if it is) is that there are dual "bootable" drives, motherboards, processors
(or processor systems), ethernet cards, video, ... other stuff with the
shared data "between" the servers. If you drop the "authorized" side with
the ethernet address that you used, the adlm is down. If you can't get to
the network card with that ethernet addr, then all bets are off.
What you can do is pull the ethernet card out (assuming that it works) and
cram it in another machine, repoint clients as req'd and you're back.

Will it work on a cluster... Probably. Will it work on fail over...
Probably not (assuming that anything I know about clusters is correct). If
it's that important to keep acad up look at the distributed model.

Thanks Jason.

Would I even need to install it on the cluster itself? Or can I just install FlexLM on one of the nodes and have that node be the License Manager, instead of the cluster server being the License Manager?

Thanks

Again, not a cluster server expert here (Interpretation: I don't know
anything about clusters) but, my guess would be that you can install it
on a single node of the cluster (as long as it has it's own network
card, and OS drive (and actually it must have a C: drive or Flex won't
start) it should be fine (notice I said should). This will likely be an
"unsupported" configuration and I've never tried it, but in theory it
works.
