A. Hot adding memory allows you to add memory to a running operating instance without a reboot. This applies to both OSs installed on physical hosts and those in virtual environments.
OSs that support hot-add are listed below. Note that the version listed and higher versions are supported—Windows Server 2003 is listed, so Server 2003 SP1, SP2, and so on also support the feature.
Server 2003 Enterprise and Datacenter x86
Server 2003 SP1 Enterprise and Datacenter x64
Server 2003 SP1 Itanium
Windows Server 2008 (and R2) Enterprise and Datacenter x86 and x64 and Itanium
Note that none of these OSs support the hot-removal of memory.
