KVM based Enterprise Virtualization 3.1 can now support extra large virtual servers with improved live migration all over the storage systems. Few days back, Red Hat increased its open source option to VMware and Microsoft, Enterprise Virtualization 3.1 with additional facility to escalate heavy virtual machines and access the goals of live migration all over the storage systems.
Chuck Dubuque, the senior manager of product marketing at Red Hat stated in an interview, Enterprise Virtualization 3.1 lets the development of virtual server by allowing as more as 160 virtual CPUs and memory of 2 TB. This kind of technique is bigger than maximum 1 TB of memory and 64 virtual CPUs, which is supported by Microsoft System Center’s Virtual Machine Manager or VMware’s vSphere 5.1.
According toDubuque, “The meaning of extra large virtual machine that has ability of running under Red Hat’s 3.1 systems is that “Enterprise Virtualization 3.1 can take the largest x86 boxes and virtualize them, those with eight CPU sockets with 10 cores each.”
In addition to above mentioned factors, the extra large virtual machines are supporting the proficient kernel virtual machine hypervisor that consumes the memory manager and along with this, it also uses scheduler within the Linux kernel. This is one of the many reasons why in Hypervisor performance KVM takes 19 out of 27 published SPECvirt_sc2010 benchmarks. This is a broad-spectrum benchmark which ahs been derived from the previous VMware VMware benchmark.
Dubuquefurther said that 3.1 lets the live storage migration of a virtual server’s virtual disks from rack to rack and all over the data center, however right now its stage of technical management does not support shifting from a data center to another data center. He further said in this regard that storage live migration is “within a data center or where there is a significantly high bandwidth/low latency network between data centers.”
