Hyper-V, code-named Viridian, is hypervisor based virtualization for x64 versions of Windows Server 2008. The Hyper-V hypervisor will also be available as a stand-alone offering, without the Windows Server functionality, as Microsoft Hyper-V Server.
Microsoft has been giving public users a taste of its virtualization offering with Beta releases of Hyper-V since December 2007. Microsoft also released a Community Technology Preview (CTP) of Hyper-V in September 2007.
This new release candidate includes three areas of improvement:
* An expanded list of tested and qualified guest operating systems including: Windows Server 2003 SP2, Novell SUSE Linux Enterprise Server 10 SP1, Windows Vista SP1, and Windows XP SP3.
* Host server and language support has been expanded to include the 64-bit (x64) versions of Windows Server 2008 Standard, Enterprise, and Datacenter editions in various language options.
* Improved performance and stability for better scalability and high throughput workloads.
Despite Microsoft’s image as a market dominatrix, the computing giant may have a tough time chipping away at VMware’s dominance in x86 virtualization, said Charles King, principal analyst with Hayward, Calif.-based Pund-IT, Inc in his weekly Pund-IT review today.
“The conventional wisdom around Microsoft’s market impact tends to follow a common theme; that the company’s sheer size makes it a serious competitor wherever it decides to play, but we see a number of obstacles in the way of Microsoft’s leadership goals,” King wrote. “First, though the x86 virtualization market is relatively small (Microsoft estimates that only 10% of servers are currently virtualized) VMware has found a remarkable number of Fortune 1000 customers who drive significant sales and revenues.
“In addition, those large companies tend to be among the most conservative of IT users; once they choose a reliable technology and vendor they tend to stick with them through thick and thin,” King said.
But considering its relatively low entry price of about $28 per Hyper-V Server, Microsoft could be the pathway to virtualization for a wider audience than other high priced players like VMware have been able to reach, King reported. If purchased standalone for hard-drive installation, ESX Server 3i list price is $495 per 2 processors, according to VMware’s website. “If Hyper- V’s features prove to be as robust and beneficial as Microsoft claims, the company could become a significant virtualization player for years to come,” he said.
