Microsoft launches Hyper-V R2

Bkjia.com: VMworld conference sponsored by VMware is held in San Francisco. In the opening ceremony, Microsoft initiated a challenge to the system management program of VMware's ESX Server. It released its own free download version of The Hyper-VSever2008 R2 hypervisor.

If you are keen on Microsoft-style Server Virtual Machine software, you can download Hyper-V R2 here.

Hyper-V R2 is an independent hypervisor, which means you can use it independently or use it as an additional part of Windows Server 2008. According to Microsoft's download website, Hyper-V R2 requires at least 1.4 GHz processors and runs on a 2 GHz or faster chip that Microsoft recommends. These chips must solidify Intel VT virtualization technology) or AMD-V management programs. Some security features, such as Intel XD and amd nx, need to be supported on the chip.

The progress of Microsoft's accelerated R & D has enabled Hyper-V R2 to provide online migration functions like all mature management programs currently, so that the load working on the hypervisor of one server can be transferred to the hypervisor of another server over the network while they are still running ). This function allows the server to run continuously without shutting down the application. So far, for many small and medium-sized enterprises, this feature has limited disaster recovery beyond their IT experience and budget to a very small scope. In fact, Hyper-V R2 contains a feature called high availability, in which a specified backup machine on the network crashes, it automatically restarts the virtual machine running on a server.

The online migration and high availability features of Hyper-V R2 can be achieved from system center VPC manager 2008 R2, from Windows Server 2008 R2 and its failover Cluster Manager/Hyper-V Manager tab, or from a similar free) manage in the Failover Cluster Manager/Hyper-V Manager tab-Microsoft is embedding the Windows 7 client to be launched.

As early as May, jeff Woolsey, managing Microsoft's Windows Server and Hyper-V project, boasted about how Hyper-V Server 2008 R2 management software is cheaper than VMware's vSphere stack-vSphere stack costs from 13,470 three-node cluster of x64 servers in two slots) from $44,900 to a five-node cluster of four slot servers. There are also many ways to reduce VMware pricing, and these methods are not bragging. However, supporters of VMware quickly pointed out that their remarks are full of vulnerabilities.

Surprisingly, even with so many free alternatives, VMware still occupies a sufficient share of data center deployment when it comes to x64 virtualization. The reason is simple. VMware is a security choice, such as IBM mainframe and minicomputers over the past few decades, as well as Unix servers for HP and Sun Microcomputer-level systems in the Revolutionary open system field. Although we can talk about the millions of Hyper-V licenses issued by the data center, the first version of Hyper-V lacks the key features required by small and medium enterprises and large enterprises. It is probably reasonable to guess that most downloaded Hyper-V and licenses are not used. Just like before it was sold to Oracle, Sun boasted to issue millions of Solaris 10 licenses, either just for Wall Street, or for other purposes.

Undoubtedly, Hyper-V R2 is a watershed for Microsoft and small and medium-sized enterprises. This version may be good enough for many companies, and it is more suitable for enterprises that have been plagued by catastrophic recovery problems and flexibility in the past.
VMware has many advantages. For example, it has a free ESXi Management Program, and soon there will be a free host management tool running on VMware targeting small and medium enterprises. However, Microsoft is the security option for many small and medium-sized enterprise customers. It will be interesting to see how Hyper-V is installed-without downloading, or using a certificate or a server or DVD-this is actually an installation method for ESX and ESXi. The Citrix system and XenServer also have problems in this regard-not to mention the Red Hat and enterprise-level virtual machines. Even the implementation of Oracle and Xen has such problems.

This competition is not over yet, and everyone seems to have their own opinions on how it will evolve. Although both VMware and Microsoft like to have won the competition, the competition in the virtual machine market is not a round, which is a long-running battle. Of course we can argue about how long it will last ).

It can be determined that there will be some different battlefields on server virtual machines: free release, designed to improve customer awareness, facing small and medium-sized enterprises virtual machines; high-end, sophisticated, and usually expensive tools targeting large enterprises; and more complex things are said to be aimed at public and private cloud computing. It should be pointed out that there are no customers who have used these virtual machine tools. So far, Amazon has basically deployed cloud computing and is already using its own Xen stack.

It is silly to think that Microsoft will not compete in these aspects. But then again, VMware has been sticking to its territory. Citrix has been transformed over the years by relying on technological changes in desktops and data centers. What is really uncertain is what makes fighting more interesting.
