Memory allocation in win2008 64 Bit VM under VSphere
Posted on 2010-11-25
I have a Vsphere ESXi 4.1 server with a windows 2008 64 bit server VM running in it with 4096 mb memory allocated. We are running a 32 bit app (called Class) with 32 bit Ms-Sql 2003.
At times, when running reports, this server will respond very slowly causing our web server that interrogates the DB to deliver timeout pages as the data is not retrieved in a timely enough manner. We can see that memory consumption at this time is 96% (approx).
If we were to increase the memory on the windows server under VSphere does anyone know if the server and or applications would be able to make use of this extra memory space or is that outside of the applications addressing space capabilities or for that matter the operating systems.
It's just that I remember windows systems have a limit of 4GB address space and I am not sure what combination nowadays enables the OS or apps to get past that??
Your advice and thoughts, as always much appreciated.
