How to choose server virtualization hardware platform? – Selection of virtualiza
IDG Consulting China's virtualization market is divided into three phases: 2010 for the implementation stage, 2010 to 2015 as the growth phase, about 2015, entered the mature stage. Among them, 2010 Virtualization Software And services market was 924 million yuan, up to 3.179 billion yuan in 2013. Its average annual growth rate of more than 36.3%, the market promising.
From the technology point of view, virtualization can also be divided into three stages: the first is virtualization 1.0, this stage Server For the purpose of integration, the main goal is to save operating costs. The second is the virtualization 2.0, at this stage more emphasis on the dynamic distribution of computing resources, the flexible and efficient management as an appeal. The third phase of virtualization is virtualization, 3.0 times, the main features of an enterprise cloud computing, the pursuit of resources, scalability, return on investment as a consideration to the goal. Different stages of virtualization, goals are different, the methods used are different.
To virtualization 1.0, for example, the main goal of integration. Either through existing Server Integration, you can also buy a new server on the old systems integration. Generally speaking, x86 server life cycle in about 5 years, over the years, on the one hand equipment close-out, on the other hand parts in the market has also been difficult to find. Therefore, the need for upgrading the server to ensure the stability and reliability of system applications. PV with virtualization capabilities, you can apply some of the old system, migrating to the new system environment, the so-called virtualization capabilities benefit the old. Even within the life cycle, there are excess computing resources to buy situation. According to the business users will often need to purchase the maximum amount calculated, and the appropriate computing resources set aside part of its excess computing capacity result. Data show that the utilization of server computing resources, less than 30%, virtualization can be enhanced by 85%, which means fewer servers can meet the needs of users, not only more green energy, and management easier.
However, with the full use of processor resources, virtualization on the server Memory , I / O put forward higher requirements, it would be difficult to play overall system performance. Users should select Memory Support the ability of the server. Used the server to IBMx86 unique x structure, for example, in the memory and I / O support on, there are a lot of originality. The current structure of the new X server, using the fourth generation IBMeX4 chipset technology. For example, System x3950M2, it is a six-core processors with 4-way server, through the adjustment of memory, users can more fully use their advantages of virtualization, will reduce overall energy consumption by 37%. The same Systemx3850M2 is a unique six-core 4-way server, which can be extended from 4 to 16 way, users do not need advanced computing resources to buy unnecessary.
In short, for the selection of server virtualization platforms, requires the user to choose according to different needs. Even if the server is to select same grade and pay attention to their memory, I / O and other differences in configuration, select the memory as soon as possible to support larger servers, select the high I / O bandwidth product. Specific problems, individually.
