Windows 2008 Top Ten Practical Improvements (1)

        Everyone, a server that was pre-installed with the official version of Windows Server 2008 in English, measured a number of new features. I feel that Microsoft is really moving this time! Compared with 2003, 2008 can be said to be reborn, and Linux will face a more severe test. If you don't look at the ¥, Linux can almost be sentenced to death! The following are ten new features that I think are very useful: First, Server Core thin server installation mode, this is a very good improvement, many people have said that under the same hardware conditions, Linux as a server performance must be stronger than Windows Server, Because Windows has a graphical interface, there must be performance loss. Now that Microsoft 2008 has finally made important adjustments, 2008 can be installed as a version with command-line mode only. And I really like that he can insert standard function modules in the same way that game consoles insert cassettes. At present, Microsoft has developed 8 "game cards" for network services, including DNS, DHCP, FTP, SMB2, IIS7 and other network services are supported, and the .Net Frameworks Core version is also under development. Since Server Core's "cartridge" is based on Microsoft's own products, it can be said that Microsoft is managing and setting up the X86 server as a hardware router. What kind of leap will it have in terms of performance, stability and security? Microsoft claims that PHP runs under IIS7 Core at a performance eight times faster than 2003. So I think this improvement is one of the deepest aspects I feel. Second, PowerShell command line operation mode, in view of the 2008 version of the server version based on the command line mode, PowerShell as a command line management tool, can be said to take it for granted. However, the functions of PowerShell students are too exaggerated. At the same time as the various functions of the operating system are set, it is too much to do all kinds of calculators! Microsoft is simply the WSH scripting engine to do the basics. PowerShell's command-line operations will definitely control every hair in 2008 (of course you need to have the device "hair" installed on your server! Hehe!). Dear brothers from the DOS era, be prepared, we need to buy at least one PowerShell technical manual. Third, the forced restart technology, brothers who do Internet services have had such experience, the server is used because of a bad software, occupying 99.99999% CPU resources, when the remote desktop server is restarted, the remote desktop service is broken. After the opening, everything can only be resigned. Who knows if the server can be executed until the last successful restart, and will not get stuck? In the 2008 era, Microsoft finally provided a powerful shutdown method. After receiving the shutdown command, it was guaranteed by the system service level priority. No matter what happened, your server will make a "beep" after 45 seconds. Everything will become beautiful:) Fourth, the core work agent technology, in the past software developers, in the system of reading and writing the registry, replacing the driver, the hook on a system Dll, etc., are directly carried out. In other words, if you want to rewrite a registry content, and an anti-virus software thinks you are malicious, it is very "timely" to stop you, and your program is changed half of the registry and half of the registry has not been changed. Finally, the blue screen of "嘣". Sorry, your system may be hung up, please go back to the guest. Now that the core access agent technology is different, he changed the way to access the core layer directly in the past, but through your task, he conducted a "parliamentary system" integrity check (that is, he would ask other software to say that you have no opinion. Then I have to start 喽!), and then make a real change. If there is a problem with the modification, he also supports the rollback operation to ensure the integrity of the registry. (In fact, this mechanism has been used before, still remember the "Reply the last normal start" option, how simple the XP era is!) Five, WHEA hardware news, when I saw this feature, I am a little emotional! I wanted to be in the Windows 95 era when Microsoft just proposed PnP technology. Hardware vendors are under the DOS platform and suddenly turn to Windows drivers. How many blue screens, how many illegal operations, are caused by system drivers. Ten years have passed, and Microsoft has finally completed the unsuccessful dominance of the hardware driver standard. Today 2008 and Vista go one step further in terms of drive standards. Microsoft will command all hardware messaging standards. If your graphics card has a headache or a fan stop, it will be reflected in your system event through this standard interface. Previously, the server system was blue screen, and it was difficult to find the reason for the blue screen because the information given was too simple. Now 2008 and Vista can actively record a lot of hardware messages, and after a serious error occurs, give more reasons for driver-level failures, so that everyone can find the perpetrators. Sixth, virtual server technology, Hyper-V technology should have been heard by many people, almost talked about the new features of 2008 will mention this technology. What I want to say is the difference between the 2008 virtual machine and the VMware virtual machine software. a) The 2008 virtual machine is implemented based on the underlying platform, while VMware is at the application level. It can be said that 2008 has made a lot of foreshadowing of virtual machine technology from the infrastructure level. I think VMware will specialize in a version of 2008 in the future, and VMware will become the management software for the 2008 virtual machine. b) The 2008 virtual machine must work on x64 processors, which means that only the 64-bit version of 2008 supports virtual machine technology, and VMware is currently not subject to this limitation. It should be said that the 2008 virtual machine technology is not designed for personal use

. The x64 architecture CPU is in the instruction level, whether it is intel or amd, and it is an important optimization for the virtual instruction environment. c) The virtual hardware technology of the 2008 virtual machine is very powerful. It can be said that what hardware is configured on your server, and what hardware can be loaded into the virtual machine (the graphics card is also included, but it still cannot support 3D games). As VMware knows, his hardware relies on dedicated drivers developed by VMware. d) The main design of the 2008 virtual machine is intended to provide dozens of virtual servers for different purposes on a server with a lot of chips and large memory like a minicomputer. This fundamentally solves the demand for various servers in enterprise network informationization, and reduces management costs and overall input costs. In the past, your business might need: VPN routing server, database server, DHCP server, AD server, Exchange server, etc., and you buy server equipment far higher than the current demand in order to reserve some load potential. You don't need to do this in the 2008 era. You can buy one server first, then actually run 4 or 5 virtual servers, and you need to expand it in the future. Simply add one server and put several virtual server resources. Copy it over, restart it, and you will be expanded in a few hours. In addition, your server power supply is suddenly damaged, the new spare parts can only be sent after 48 hours, the network service can not be stopped, reinstall another server to replace, at least 24 hours, and then set up the domain account and database again Exhausted you. Now you only need to take the hard drive and copy a few files to the new machine. The virtual machine is perfect to run safely under the new environment. e) In terms of virtual servers, 2008 really opened up a new era, and Microsoft should be proud of it. 7. ASLR memory allocation technology, in fact, I think this random allocation of memory address technology is definitely not the purpose of others to prevent hackers from attacking the system by means of "memory overflow". He is more concerned with the allocation management work of more than 4GB of memory, as well as the future development trend of hardware-based multi-chip, multi-channel memory resources. Future hardware is likely to support the technology of dynamically inserting memory sticks or dynamically allocate virtual machine memory through virtual machine technology. If you can't put the memory used by the system in any memory location, these assumptions are empty talk. It is foreseeable that Windows 2008 and Vista will be safer and more thorough in terms of PnP (Plug and Play) technology in the future. Eight, SMB2 sharing protocol, the past SMB1.0 is matured after Windows 2000, file remote sharing access protocol. However, there have been several problems in the past. For example, in the Gigabit network environment, the file copy speed between the two computers is only about 250MB. There is also a problem of poor bandwidth utilization efficiency through a VPN-based WAN connection. This is caused by the fact that the SMB 1.0 protocol itself has not kept up with the development of technology. SMB2.0 greatly solves this bottleneck by further optimizing the file reading and writing process and the network transmission process by providing technologies such as a larger packet buffer and a single file concurrent I/O pipeline. In addition, SMB2.0 has also enhanced security in terms of LAN access control. Nine, IIS 7.0 WEB service, this improvement I think the most intuitive feeling is that the component installation method. Previously, IIS 6.0 was installed by default with COM+ access and .Net support. Now that IIS 7.0 is installed, it is the simplest HTTP server. You need to install it. The configuration file for IIS 7.0 is completely implemented using an XML configuration file. You can use the copy to back up and modify the IIS settings. There is also a very useful thing, this time IIS and FTP have a link status view, and finally analyzed without the complicated performance tracker. Ten, BitLock disk encryption technology, in fact, we have been complaining that Vista copy files are twice as slow as XP. In fact, it is not difficult to understand what causes BitLock technology. Microsoft is considering the need for data encryption from the system I/O layer this time. If GX brother uses Vista's function earlier, it won't be so big. This 2008 and Vista are the same underlying architecture, so we can use a domain control policy to encrypt a folder on a local or remote hard drive. The encryption level is very high. It can be said that if you forget the password, Microsoft will not save you. The data is gone. In the future, with the SMB2 file network of the domain control server in 2008, you can realize that your notebook can open this folder in normal operation, take home and do not link VPN back to the company, then no one wants to open the information in your computer. In fact, there are still many improvements in 2008, such as the restartable AD service. It used to be a headache to repair the domain control server. Even if there is a secondary domain control, I have never been able to successfully complete the repair. come. Now the new AD service, I have not tested yet, but it seems that the current AD is very well separated from the server platform, and it has been similar to the IIS service. I will have the opportunity to test the 2008 domain control in the future, and then tell everyone about what is new. I wrote so much in one breath, but not enough to express my surprise for the quality change of 2008, but I predict that 2008 will soon replace the server status of 2003, and the brothers who manage the server will make plans early!
