In a new blog, Andrew Theurer, Senior Software Engineer, IBM Linux Technology Center, examines the SPECvirt sc2013 results achieved by the IBM Flex System x240 server with Red Hat Enterprise Linux 6.4 with its Kernel-based Virtual Machine (KVM) hypervisor, and explains how the SPECvirt_sc2013 is different from the SPECvirt _sc2010:
Virtualization is often used to reduce the hardware required to operate a data center, and the more servers one can consolidate on to a virtualization host, the fewer host systems one needs. This of course results in much lower operating costs due to fewer required software licenses, less energy consumed, considerably less space needed, and fewer administrators. So, in order to decide which solution is best for you, it's vitally important to be able to compare VM density among different virtualization solutions. One of the ways you can do that is with the industry standard virtualization benchmark, SPECvirt_sc2013.
