VMware, whose virtualisation software helps IT departments maximise use of their server hardware, said yesterday that its product will run reliably with software from Microsoft.
VMware has certified its ESX hypervisor to work with Windows Server and other software from competitor Microsoft. The move also gives customers using ESX technical support from both companies to deploy VMware virtualisation software on Microsoft infrastructure.
ESX update 2 is the first hypervisor to be certified through the Microsoft Server Virtualisation Validation Program, introduced by Microsoft in November 2007, according to VMware.
The program enables vendors to test and validate virtualisation software running on Windows Server 2008 and previous versions of the OS. It also enables Microsoft to offer cooperative technical support to customers running Windows Server on validated virtualisation software other than Hyper-V, its own hypervisor.
VMware remains the leader in selling virtualisation software, which allows multiple and different OSes to run on one piece of server hardware. According to IDC, VMware had 76.4 percent market share in 2007, followed by IBM with 9.8 percent.
However, competitors -- particularly Microsoft -- are hoping that won't be the case for long. Microsoft released Hyper-V earlier this year as a competitive offering to ESX and the hypervisor of choice for Windows Server. At the same time, Microsoft also realises it must work with other virtualisation vendors, which is why it introduced the validation program last year.
