How to create a VMware vSphere virtual machine utilizing all available features

Step 9: Assign the virtual memory

Without question, the most critical decision point in creating a virtual machine is the amount of virtual memory to assign a guest. Like vSMP, memory allocation should be exactly what the application and operating system require. vSphere supports up to 255 GB of RAM on a virtual machine. VMware’s memory management technologies allow oversubscription of the guest compared to the host’s RAM inventory, which means there may be swapping involved if the allocations exceed the available memory after the other memory management technologies such as the balloon driver, transparent page sharing, and memory compression.
