We have some physical servers running a memory intensive app, and are looking to move them to virtual ESX.
At the moment, the physical servers are Windows 2003 x32 Server Std. They have 4GB RAM.
The virtual servers would be the same.
Would I be correct in thinking that as long as we assign the ESX guests 4GB RAM, the performance *should* be the same, in terms of memory availability? Or does it depend on the memory consumption of other guests on the host etc.
