Sign up with GoogleI might be mistaken but from what I read up and done myself it works like this.
ESXi 3.5 is 32 bit. It sees more than 4 gb ram and it can run 64 bit vm's. The running of 64 bit vm's has to do with the CPU and not the Hypervisor it self.
ESXi 4.0 is 64 bit. It will run 32 and 64 bit vm's.
The memory limit on both of them has to do with the VM's them self. I.E. Windows server 2003 32 bit vs Windows Server 2003 64 bit.
Coming to the raid issue. No fake raid will work on ESXi (I havent found one). Fake raid includes the on board raid systems on almost all Intel server boards. Get a descent raid card, and try and get your spindle count as high as possible. When you start to run load on the server and HDD access increases you will want the extra spindles.
There are also issues with network cards. ESXi only likes server cards, i.e. Intel E1000 3com etc cards.

This is only a guide, compatibility might change.
