This can matter if you want to use portable hard drives or USB key drives to move data around. What we did at work for our off-site backups was to stick an eSATA card in the host and plumb it through to the guest with device pass-through. This only works for certain CPU/chipset combinations. You might also have to twiddle a virtualization-related BIOS parameter or two to make this work. Also... ESXi 3.5 _will_ work on 32-bit hosts; ESXi 4.x will not (we have a mix here). That also have implications for what emulated hardware types are supported (especially if you are loading VMs created elsewhere). Specifically, VMware hardware type 4 works on both platforms, but hardware type 7 won't work on ESXi 3.5. All that aside, I have spent a lot of time working with this platform and have a much happier experience with it compared to its immediate predecessor (VMware Server 2). It's much more stable (400+ days of uptime and counting) and with the exception of lack of USB passthrough, it's been a fabulous experience. So far, I've mostly run Linux as the guest OS on the VMs, but I know the platform supports DOS and Windows guests; we just don't have much call for that at work. -ethan
