Microsoft Virtualization deployment Application and management process detailed

Fang Jianguo: I'm glad to have the opportunity to meet you today. To discuss some of the Microsoft Virtualization solutions, before we on December 20 in the once did a virtualization salon, we did a virtual migration and virtual machine management work, today time is limited, can not do virtual machine migration show, Today we will introduce Microsoft virtualization solution, and then we will introduce you to use SCVMM2008 to manage ESX, reflect the Microsoft's virtualization solution in the management of the application of some advantages.

We all know that virtualization is a very hot topic, these two years generally mentioned virtualization, we are basically flocking, because the virtualization can be in it to meet some of the problems to do a very good solution, now we encounter a lot of problems in fact is the server utilization is not high, and lead to maintenance problems, High availability poses some problems, I was in the news this piece has done some operation, to this piece of deep experience, the earliest time we have a limited number of servers in the early 90 when the size of about dozens of units, and then with the rise of and pick station, the number of servers began to increase, began to add to hundreds of Taiwan, Obviously the management maintenance this piece of difficulty increases a lot, later, with the increase of these users, the number of servers in these years is growing very quickly, we in 07 time to server more than 200 units, so many servers maintenance is very difficult, and everyone is very headache, these server utilization is not high, Sometimes we in order to meet an application, we must set the server according to the application of the upper limit, for example, we have been on the chat server, peacetime load is not heavy, we can run up with SUN4500, and then we invited a network selection of Champions to do a chat show, this flow soared, As a result, the server crashed, we are very embarrassed, we would like to use this opportunity to improve the image, the image will be messed up, the engineers have done a tight repair, we can only restart again and again, the next time in order to avoid such a situation, we have increased the number of chat servers, in fact, this server utilization is very low , usually no celebrity patronage, the utilization rate is only about 10% to 20%, is obviously a very serious waste.

Why are these two years of virtualization so popular, in fact, virtualization to improve the utilization of a good solution, you want to use virtualization can improve resource utilization to reduce costs, which obviously for the entire business of the normal operation of the benefits, generally we know that we do it this piece know, It's the one we think is the most important cost, often denounced to the boss, and how much money, now we can use this thing as a way to save money, which is why IT managers are so interested in this thing.

Virtualization is the logical use of a physical resource into a resource through a technology, using virtualization from now on, there are several benefits, reduce overhead, improve the feasibility, improve management maintenance, in the virtual machine migration can make some contribution, according to Microsoft for it enterprises to divide four standards, Microsoft believes it enterprise basic type, The standard type, the reasonable type, the dynamic type, dynamic is the use of all resources as a pool of resources, the abstract is that as long as the demand for resources to ask, you can think of this resource to become a service, the specific resources how to schedule, how to achieve the need to do, for everyone is a transparent process, Can basically do that. Dynamic Enterprise is the IT model that Microsoft thinks ideal enterprise. Of course, there are few that can reach this standard.

Today we talk about Microsoft's virtualization products, Microsoft in the field of virtualization in the face of a lot of products have tried, like Microsoft in the terminal virtualization, through the terminal we have some servers even if not, we can connect to another machine through the terminal to use these software, The application of virtualization Microsoft also has a more prominent solution, Microsoft can through a number of programs such as Hyper-V in a machine virtual a software application environment, would have to do an application, the operating system could not run this program, but through the application of virtualization can be a virtual software operating environment, Desktop Virtualization This people use more, 2007 people do experiments often use, including server virtualization, server virtualization before there are solutions, 2005r2 and so on, with more, Microsoft in 2008 for the field of virtualization cast a blockbuster, Hyper-V, It is Microsoft in the Virtualization field of a flagship product, is Microsoft's high expectations of products, Microsoft in 2008 first in the Windows200864 bit server integrated Hyper-V Virtualization Server implementation, and then released a separate version, Hyper-V 2008 Server, which actually provides support for another interface with an organizational interface.

Today we are focusing on server virtualization, as you can see, before the server virtualization, the architecture is basically silo mode, each hardware and operating system and applications and interfaces are closed, isolated, obviously this mode of hardware utilization is relatively low, after the server virtualization, We can see that we can run multiple server operating systems on the same hardware, so that when we run out of multiple servers on the same hardware, the multiple operating systems can be viewed as multiple applications that can run on the same interface, improving hardware utilization. If you use Microsoft's Hyper-V also support some of the load-balancing solutions, if one day the machine on the resource load too much, then you can transfer resources from one physical machine to another physical machine. And if a computer has unplanned downtime, this is also achievable.

Server virtualization is most obviously a significant increase in server utilization, the reduction of the number of people generally think that Microsoft to the solution, you can 32:1,32 1 units, integrated to 2:1 or about 3:2 or so should be within the normal range, the number of servers reduced, electricity will save a lot of Under normal circumstances, a common server running about two years and the price of the server is almost, do not know if we have to maintain the pain of the thousands of servers on the hundreds of platform, I remember very clearly once, we from the telecommunications side of more than 400 servers moved to Tanggu, the process is busy, I very much hope that these servers if the number can be reduced by one-tenth, this process will not be so painful, we do this work when the girls as boys, the boys as animals, we hope that the server virtualization this piece can make some contribution to the Operation dimension.

Just now we mentioned that server virtualization has two products, one is Virtual Server 2005 is Hyper-V 2008, the latter is the 2008 Microsoft released the most important flagship products, this product and the advantages of the previous products in what place, we can see from the screen, Two different structures, the former is the need for operating system support, the need for 2003 of such an operating system, and then through the operating system to gain control of the page, it is obvious that the way integration is better, but this approach is obviously the implementation of the hardware efficiency is quite low, presumably to pay some performance costs, This is why the lack of hyper-V before the emboldened is not very sufficient, now with this product, from a visitor into a competitive protagonist.
