Fewer, big servers vs many, small servers in a virtualized infrastructure

by Joe Gleinser 24. September 2009 02:31

HP's Proliant G6 maxes out at 144GB of RAM. 16 core processors are due out in 2012. How many VMs can you cram in a quad, 16-core box with a 144GB of RAM? Enough. Arthur Cole describes trends toward both mainframe-style aggregration and grids of smaller systems. Which is right your for you? One factor in determing the best strategy is:

Additional servers reduce the overhead for virtulization failover. Much like RAID configurations, with 2 servers you must allocate 50% overhead for failover capacity on each server. Three servers only need 33% overhead and so on.
