Optimal Configuratrion

I am running server 2012 with 32gb ram, 12disk array.
What is the optimal configuration for performance with single node?
It sounds like the virtual disk is recommended to be faster than a raw disk?
What about cluster size of the windows partition the vdisk sits on?

Single-node configuration is not recommened as it's not safe to use a write back cache which is a huge performance booster. So at least dual node HA is recommended for production.
Yes, we don't use OS file system for anything except actual data allocation (all I/O is done in pass thru mode and we keep own block cache for L1 in RAM and L2 in flash) so virtual disk is faster then a raw disk
because of the advanced data commit technique we use (would be even more the case for upcoming V8 with its ability to do a log-structuring with LSFS).
Cluster size does not matter as we don't do file I/O with the file system services.
