For guys that have virtualized their ISA Servers be it Hyper-V or on ESX how are you addressing SSL-Offloading?
I have servers that have pci-SSL cards in them that I want to virtualize but don't know what to do especially where Exchange 2007 is concerned.
Please share your setups.

Thanks

Modern CPUs with scaling out of servers normally negates the added load of SSL processing nowadays; especially if using multi-core CPUs.

The other opption is to use an external hardware load balancer that can do SSL termination in front of ISA...

You looking at huge numbers of users?

Cheers

I kind of did think that this may of changed with new Procs but was not too sure. I don't have that many users currently (maybe 150) but this will change rapidly soon.
So you reckon I'll be Ok starting out with a single vCPU and adding more as demand grows?

Yeah, you can also add other array members if you go for ISA Enterprise Edition for scale out...
