“He adds that companies normally allocate about 1Gb of memory for Windows 7 when not using dynamic memory, which may be a waste. â€œIn tests, we found that when you allocate a nominal 512Mb of RAM most of the virtual machines averaged out at 750Mb of RAM,â€ he explains. â€œThat gives you a 40 per cent increase in the density of the virtual machines that can run on the server, improving cost effectiveness.â€”
Chuckle. I budget about 512 MB for the OS and 100 MB per user giving 1000% cost effectiveness, but then, I use GNU/Linux and good old X. IT really handicaps itself when it limits choice to that other OS.
X has limitations in video throughput and security but it is the lowest cost solution where these issues are minor as in many libraries and computer labs.
