Don’t bother going the clustering
route. ISA has a very decent version of NLB that’s built in, and will
work in a highly available configuration for a single route.
Adding clustering to this will obscure and
complicate things. Suggest you stick with the built in NLB, since adjacent
Proxy servers can be “aware” of each other, and can take on the
other boxes load transparently.
This has the obvious advantage of taking
you into a MS supported configuration, and allows you to “scale out”,
i.e. NLB, using dissimilar hardware, as opposed to “scaling up” and
clustering using matched hardware.

The real question here is: "Will Microsoft support ISA running
under VCS?". That is a question that only Microsoft can answer so I would
send that question to your TAM, or if you don't have a TAM call into PSS and
open an Advisory case to get an answer to the question.

Hey guys,
Thanks for all these...now let me go a step further...what if a company wants
to consolidate their applications,build redundancy, failver capabilites and
implement clustering as well using Veritas clustering Solution....can ISA be
treated as a microsoft application that can be clustered...?? And if yes..whats
the best way of doing it...apparently not too many companies have towed this
line..but what if it can be pulled of..whatcha ya all think...??
thx

Maybe not in the ordinary sense, Brian. But in the ISA 2004 Enterp realm, we
should be able to do that. OR, if you prefer, we can say "tomato" and
"ketchup" or something. NLB is the way to go in ISA 2004, and the way
ISA uses NLB (in addition to the new "Configuration Storage server"
concept, you do indeed have some resilience that is not usually available in
the "normal"
NLB deployments.
The only time I've seen ISA installed in another "clustering"
configuration outside of NLB is when "Rain Wall" was used. Of course
I haven't seen every ISA server installation, but I'd wager that NLB is
generally considered the standard "clustering" solution for ISA 2004.

Clustering and Load Balancing I wouldn't really call a tomato tomoto thing.
More an apples and oranges thing. Load Balancing is not a fault tolerant
solution, whereas clustering if something breaks everything moves over to
another node...

Greetings Aramide,
I do not believe that Microsoft ISA server 2004 can be clustered per say using
Microsoft Cluster service. I took the ISA server 2000 & 2004 class and the
MOC stated that the ISA 2004 Enterprise
edition is designed to be load balanced which I believe would solve your issue
( It's just a terminology thing. You say tomato, I say tomoto... ) :-)

Hi guys,
A quick one...does anyone have any idea where I can get documentation on
installing ISA 2004 Standard/Enterprise edition on a Microsoft Clustering
Solution.
Kindest Regards
