Today , vendors hope that through extensive virtualization technology enables businesses to get in on the substantial growth in the server market , but this desire affected by the economic crisis on their business due to make server sales did not increase but more conservative . At a time when VMware, Citrix , Microsoft and other virtualization products hyped promotion , enterprise users need to run virtualized difficult to increase investment in cost management application server products.

As the two market analysis firm Gartner and IDC said that although virtualization has in-depth business, but they still use a lot of the number of physical servers , as if blind to the consequences of the use of cost savings, virtualization is a direct result of virtualization technology enterprises will get closed down. This is not an alarmist , when only five per year " server " sold to Google , Microsoft, Amazon, Yahoo and even telecommunications giant , install millions of virtual machines on each server , so to meet the needs of their business ? Perhaps IBM Watson , founder of the "World just five servers ," the thesis will be realized in the future , but now this idea is unrealistic.

Currently server installed units estimated to be about 30 million , this figure doubled in 2009 and 2012 forecasts , based on the same time as the application changes, and the number of virtual machines on the core , making the server market, but sales have decline. This is difficult to predict sales volume decreased from the impact of virtualization , but in the current economic slump , the physical server shipments will decline by 50% per year. Due to a large number of virtual machines , a small number of servers installed will drop 10 million units.

    To be sure , if this happens, the server market revenue and profit balance is broken, would cause unnecessary confusion in the market .

According to Gartner predicts that server virtualization adoption in small business growth is the fastest , but it is taken for granted, can be an effective cost-saving operations. Because corporate customers have been using Unix server virtualization technology , large enterprises also began to use a server -based x86 and x64 virtual server.

Distinguished analyst at Gartner , said earlier large enterprises use virtual machines to reduce server sprawl and power costs , so in order to save data center space . And small enterprises in the virtualization gradually began to accept and use the end of 2010 broke out, and with the increasing competition in the server vendors , high- penetration deployment of virtual machines , so that smaller companies have begun to accept the deployment of virtualization .

IDC also said that sales of server virtualization product in the second quarter of this year fell by 18.7%. While the number of server virtualization licenses growing trend , compared with shipments , revenue management program rose to 60.8% of the total management of the program.

Although IDC did not disclose specific data in its public report , but it is certain that VMware ESX virtualization product sales ranked first , though still in Q2 revenue fell 22 %. Virtualization software, Microsoft ranked third in Virtual Server 2005 also has a 16% drop. Hyper-V performance in the second quarter of 2009 is even more eye-popping , revenue declined 54%. In addition , Citrix XenServer hypervisor and virtualization management did not enter the top five selling applications .
