64 bit SQL

Why bother? Planning on building new servers in the next 6 months. Any point
in dumping 32 bit?

A little more background would help; What is your memory utilization like
in 32-bit? Are in in an Active/Active cluster and unable to take advantage
of AWE? What are some characteristics of your workload? With the
information I have right now I couldn't even help you choose your next car,
let-alone where your I.T. budget dollars need to go. =)

Current environment is a two node active-passive cluster. Currently 4
processors, 16 gig RAM. going to add 4 procs and 16 Gigs Ram this wend.
Fiber chanel to an array.
We are looking into a building a cluster with more nodes
(Active-Active-Passive, maybe).
Biggest problems are that the application is a port from an Access database
and we serve the appliction to about 200 customers, growing fast (20% per
quarter). It has not, and very likely will never be, optimized in any
meanigful way for SQL Server. Another fun thing is that each instance of
the application creates multiple database connections and leaves them open
until the user exits. This amounts to thousands of open connections at peak
times.

Any point in staying 32-bit?
Buy dual-core capable Opteron machines. The licensing fee structure makes it
irresponsible to buy anything else.|||I'd get a 2005 Ford Mustang 4.6L, Dark Platinum with Charcoal leather...

bit until the situation is more under control. All real-world reports I've
heard of are having various issues with 64-bit handling some of the basic
functionality 32-bit delivers without issue (memory leak in the dynamic proc
cache, issues with linked servers, replication, etc). If your app isn't
tuned yet, you're going to get more bang for your buck throwing intelligent
design at it instead of 64-bit / hardware.

I agree with Cris.
Whilst you are at it, why not buy a Unisys ES 7000?
If it is easier to throw pots of money at a bad application to buy hardware,
you might as well buy the top of the range as you will probably still need
it soon.
Get the application fixed, and save yourself a lot of trouble. Eventually
you will not be able to scale up any more and your business grinds to a
halt.
