ArcSDE 32 or 64bit?

I'm installing ArcSDE 10 on a Win2008 R2 64bit Server. ArcGIS Server is 32bit only. Is there any problem installing 64bit ArcSDE version. What is the best configuration?

While it's theoretically possible to store both 32-bit and 64-bit database clients and run both
32-bit AGS and 64-bit ArcSDE on a single server, it's much easier to install *only* 32-bit Esri
apps on a single host ("easier" as in several hours less hair-pulling before giving up and just
using 32-bit ArcSDE). I once set out to prove that 64-bit ArcSDE 9.3.1 ran faster than 32-bit,
and it did (a little bit) on a 64-bit Linux VM, but it didn't on a 2008 Server VM (in fact, 32-bit
may have been a bit faster). When ArcGIS 10.1 is released, AGS will be 64-bit, and it will be
easier to run 64-bit ArcSDE.

Thanks Vince, I'll keep it simple, 32bit, cheers.
