With its hypervisor, Sun looks to aid users who might have a datacenter full of small servers, each running a separate application and perhaps in use only at a certain time of the day or month, said Wilson. The average utilization of these machines is very low with customers only using 10 percent of available compute cycles.
"The idea is that the xVM Server software, which is the hypervisor software, will allow customers to take various workloads, including applications written to Solaris andand Windows, and run them simultaneously on the same hardware," Wilson said.
Featured in xVM Server is work from the Xen open-source community. Through xVM Server, Sun will extend Solaris technologies, such as Predictive Self-Healing and ZFS (Zettabyte File Server) to Windows and Linux.
Sun previously has offered its Logical Domains (LDOMs) hypervisor, but it only supported SPARC CPUs. The new hypervisor extends to x86/64 systems.
