I am currently setting um VMware vSphere / ESXi 5.5 on a DellPowerEdge2900 and since it's an older server the following question came to my mind:

Considering performance should I install guest systems as 32bit or 64bit versions? Or doesn't it make any difference at all?

Install the 32/64-bit OS versions required by your applications. Your 2900 will run either just fine. Specifically use 64-bit OSes where you need more than 4GB of virtual machine memory.
