The structure of server is basically similar to that of microcomputer, including processor, hard disk, memory, system bus and so on. They are specially formulated for specific network applications, so there are great differences between servers and microcomputers in processing capacity, stability, reliability, security, scalability and manageability. Especially with the progress of information technology, the role of the network is becoming more and more obvious, and the requirements for the data processing ability and security of your own information system are getting higher and higher. If you are stolen by hackers in the process of e-commerce, you lose key business data; If you can't access the ATM normally, you should consider the behind-the-scenes commander of these equipment systems-the server, instead of complaining about the objective conditions such as the quality of the staff.
In fact, the network server is the usual server (it doesn't make much sense if the server is not in the network). The network mentioned here can be a local area network or the Internet, depending on the purpose of the server. The server is actually just a computer with strong X configuration, nothing special. The operating system installed above may generally be windows server version and Linux. The following is the original definition of web server in foreign websites, please refer to it.
Definition: A neork server is a computer designed to process requests and transmit data to other (client) computers through local neork or the Internet.
The Neork server is usually configured with additional processing, memory and storage capacity to handle the load of service clients.
Network server refers to a node with a fixed address, which provides services for network users and is an important part of resource sharing.
What is a diskless network server 1? Brief introduction of diskless network server
What is a diskless network? In short, all the work in the network is started through the network server, and there is no need to install a hard disk. Such networks are diskless networks, and these workstations are called diskless workstations. People who have never been exposed to diskless networks may soon become interested in such networks. Each workstation saves a hard disk, and the network of thirty or forty machines saves considerable money, which may be the first impression of everyone who has just come into contact with the diskless network. Indeed, saving money is a big advantage of diskless network, but in fact, the most important advantage of diskless network is not saving money, but "management and maintenance" Administrators in charge of network management should have a deep understanding of "management and maintenance", and the main job of network administrators is to ensure the normal operation of a network. An ordinary network with a disk, such as a network classroom, if there is something wrong with the workstation in the network, it can't be turned on or online, or the software in the network needs to be upgraded, upgrade Offce97 to Office2000. At this time, the network administrator will be very busy. He will be responsible for adjusting each machine, installing new software, and even reformatting, partitioning and installing the system on the hard disk of each machine. It may not be long before the system is accidentally destroyed by students, and the installation and debugging are complicated, which delays the work and affects the normal use of users.
Therefore, a new network structure appears: diskless network. The original intention of diskless network is to reduce the cost of workstation, but it is mainly for the convenience of management and maintenance. Imagine that if the operating system files and software files used by workstations are placed on the server, the management and maintenance of the system are completed on the server, and the software upgrade only needs to be configured once, then all computers in the network can use the new software, which is really good news for network administrators. But in fact, the situation is not so simple. The traditional diskless Window95 originally introduced by Microsoft has made people lose confidence in the "diskless network". Compared with diskless network configuration, the complicated configuration of diskless network is more troublesome, and the unreasonable structure leads to the instability of traditional diskless network system, abnormal software operation and even the failure of many softwares, which makes diskless technology almost come to an end. Diskless Windows98 and Windows2000 terminal network systems came into being at this time.
applied range
The diskless network system can be applied to the establishment and transformation of network classrooms, intranets, Internet cafes, hotels, music-ordering entertainment industries and all diskless networks.
1, which is suitable for schools to establish or transform diskless network classrooms.
2, suitable for large and medium-sized companies, enterprises and institutions, business halls and other offices.
3, suitable for game bars and Internet cafes.
4. Suitable for VCD-based networks such as hotels and KTV karaoke bars.
Advantages of diskless:
Save money. Every workstation doesn't need a hard disk, which saves a lot of money. But this is not the main advantage of diskless.
Easy-to-manage workstations can automatically recover in 10 seconds. Because there is no hard disk, I am not afraid to turn it off at will or sabotage it.
The speed of 12 seconds into WIN98 is unimaginable. The server adopts high-speed disk array, plus large memory, large cache and high-speed CPU, so the response speed is extremely high, which greatly improves the performance of ordinary workstations.
Rich in content, each workstation * * * enjoys more than 240G programs, which is 6 times more than that with discs. More than 2,000 mp3s, 1 0,000 movies and 1 0,000 games are enough to make every netizen happy and make Internet cafes rich.
Good security and unique super protection function are enough to dwarf workstations with disks, not afraid of malicious attacks and destruction, realize unattended and zero maintenance, and no longer have to compete for Ghost hard disks all day.
Game Upgrade Quickly upgrade the server game is equivalent to upgrading hundreds of workstations at the same time.
Installation is quick and simple. The original network is in good condition, and it only takes about 3 hours to replace the 100 set with a diskless one.

BXP3.0 diskless system installation guide
Author: lonely German lover article Source: Cucumber Corps hits: 738 Update time: 2005-4-2
The installation software of diskless Windows XP is BXP produced by Ventura. At present, the highest version is BXP3.0, which is an upgraded version of Boot-NIC. Its working principle and installation method are similar to Boot-NIC. This paper will briefly introduce the installation process of diskless Windows XP, and explain in detail the difference with Boot-NIC.
1 BXP 3.0 overview
Introduction to 1. 1 BXP 3.0
BXP supports network-based virtual disks and can be started remotely, so workstations can be started to Windows 2000 or Windows XP without disks. It can connect the virtual disk image of the server with a diskless workstation similar to IP/iSCSI adapter to generate a virtual local hard disk without special hardware equipment or special BIOS system, so that the diskless workstation can work completely like a disk station.
BXP is a pure software diskless solution, which uses the hard disk space of the server to store virtual maps through the network, which is very different from the traditional diskless network. All processing is done on the workstation system, and the server only provides startup and access services. That is to say, when the diskless workstation runs the software, the resources consumed (mainly CPU and memory resources) are provided by the workstation itself, which is completely different from the Windows 2000 terminal. It is precisely because of this factor that diskless Windows XP has higher requirements for workstations, because Windows XP itself has higher requirements for system hardware.
The working principle of BXP is basically similar to that of Boot-NIC, which is based on network storage. In order to realize network remote boot, PXE (Preset Execution Environment) boot technology is mostly adopted at the workstation end of BXP. PXE technology can be used not only for the above diskless Windows 98 system, but also for some newer diskless software. At present, PXE technology has become an open industrial standard, which defines how network users can automatically download boot images and structural parameters. BXP uses PXE to download the boot image file, and then loads the Windows 2000 or Windows XP operating system. Newer network cards basically support PXE.
BXP server consists of some service and management modules. The main services include input/output (IO) services and login services. We will introduce these services and modules in detail in the following chapters. .
The workstation system is assigned a virtual disk file located in the related directory of the BXP server. IO service is responsible for handling IO requests transmitted from BXP clients and accessing these virtual disk image files. For large diskless networks, some IO servers can be appropriately added to share the data flow and improve the running speed. The login service is used to verify the workstation account and provide the system data of the virtual disk allocated by the workstation of the account.
Compared with Boot-NIC, the improvement of 1.2.
BXP is an upgraded version of Boot-NIC, which improves the system function, performance and stability.
BXP diskless workstation supports Windows XP operating system and Windows 2000 operating system, while Boot-NIC can only support Windows 2000 operating system.
The virtual disk of BXP is limited to 8GB at most, and the Boot-NIC can only support 2GB at most.
Server buffering mode has been added to the usage mode of workstation/virtual disk.
1.3 requirements for the system
BXP's requirements for servers
Operating system: Windows XP, Windows 2000 Professional, Windows 2000 Server or Windows 2000 Advanced server.
Service Pack: Install the latest upgrade patch. For Windows 2000, please install Service packs 2 or later. You can download the update patch from Microsoft's website (windowsupdate.microsoft).
Disk space: BXP server should have enough hard disk space to ensure the storage of virtual disk image files.
The server has a fixed IP address.
Install IE4 or above browser.
Installing DHCP or BOOTP server can provide IP address for workstation.
BXP customers
The hardware configuration of the workstation exceeds the minimum requirements of Windows XP, preferably higher than the recommended configuration.
The network card of each workstation must be equipped with PXE or BOOTP chip.
* * * The hardware configuration applications of multiple workstations sharing a virtual disk file are exactly the same.
1.4 Usage Mode of Workstation/Virtual Disk
According to whether virtual disk files can be shared by multiple workstations, it can be divided into dedicated mode and shared mode, and according to buffer mode, it can be divided into unbuffered mode, memory buffer mode and server buffer mode. The above two methods can be combined into five usage modes of workstation/virtual disk, which are introduced respectively below.
1. unbuffered private mapping mode
This working mode is the default mode of the system. In this mode, each BXP workstation is assigned a dedicated virtual disk, as shown in figure 1. Customers can modify the data of the system at will and save it.
Advantages:
Each workstation uses its own disk image independently and can save files.
Workstations can use different hardware (the hardware configuration requirements are the same to use the same virtual disk image).
Disadvantages:
Increase the network load.
Each workstation uses a separate disk image, so it takes up a lot of space on the server hard disk.
2. Dedicated mapping mode with storage buffer
In this mode, each workstation is assigned a dedicated virtual disk, the structure of which is shown in Figure 2. If the user writes or modifies the contents of the virtual disk, the written contents will be automatically saved in the workstation memory, and the results seen by the customer will be written to the disk. When the workstation is restarted, all changes to the virtual disk will disappear, just like installing a restore card on a workstation with a disk.
Advantages:
Virtual disk can be restarted and restored to its original state, which has strong anti-virus and anti-hacker ability, greatly reducing the maintenance of available software in public computer rooms. In addition, because the buffer is located in the local memory of the workstation, it runs faster.
Disadvantages:
Unable to save customer data.
Part of the workstation's memory will be hidden as workstation disk, so in this mode of use, the workstation of the system requires high memory. When running some large software, the system often fails to operate normally because of insufficient buffer memory.
3. Dedicated mapping mode with server buffer
From the point of view of the customer operating the diskless station, this mode is completely equivalent to the "dedicated mirror mode with memory buffer". The difference between the two is that the location of the buffer is not the memory of the workstation, but a file of the business server, which is used to temporarily store the data changes made by the workstation. When the BXP workstation is restarted, this temporary file temporarily stored in the server will be deleted.
Advantages:
The virtual disk can be restarted to restore the initial state, which reduces the maintenance of available software in public computer rooms. Because the buffer is set on the server, the memory capacity of the diskless workstation is low, and there will be no shortage of memory when running large software.
Disadvantages:
Customer cannot save data.
Because the data flow between the buffer and the workstation is large, the load of using the network increases.
4.* * * Share image mode with memory buffer.
In this usage mode, multiple diskless workstations use the same virtual disk image at the same time. In order to prevent the shared disk image from being destroyed, the image file must be used in buffered mode. In this mode, the buffer is set in the local memory of the workstation and the size of the buffer can be specified on the server. When the workstation modifies the virtual disk, it will be transparently transferred to the buffer of the BXP IO server for temporary storage. When the BXP workstation is restarted, the temporary files on the server will be automatically cleared.
Advantages:
Software maintenance is small, and virtual image files are shared by multiple workstations, which greatly saves the hard disk space of the server.
Disadvantages:
Customers cannot save data to a virtual disk.
The buffer will occupy some local memory of the workstation.
5.* * * Share image mode with server buffer.
In this usage mode, multiple diskless workstations use the same virtual disk image at the same time. In order to prevent the shared disk image from being destroyed, the image file must be used in buffered mode. In this mode, the buffer is set in a specific directory of the server. When the workstation modifies the virtual disk, it will be transparently transferred to the buffer of the BXP IO server for temporary storage. When the BXP workstation is restarted, the temporary files on the server will be automatically cleared.
Advantages:
Software maintenance is small, and virtual image files are shared by multiple workstations, which greatly saves the hard disk space of the server. The buffer should not occupy the local memory of the workstation.
Disadvantages:
Customers cannot save data to a virtual disk.
The network load is heavy.
Install 3 BXP servers
Before installing BXP, please ensure the following two points:
Make sure that the network protocol of the server is installed. In this example, TCP/IP, NetBOIS and IPX are added, and the IP address of the server is set to198.168.0.1.
If the DHCP service is not installed when installing Windows 2000 Server, please add the DHCP service component in the control panel → Add/Remove programs and set its scope. In this example, the range is198.168.0.20 ~198.168. If you plan to use the DHCP server provided by BXP, you don't need to add DHCP service to Windows 2000 Server. If you use Windows XP and other operating systems without DHCP service, you can only use the DHCP component that comes with BXP.
Specific installation process:
Instructions for use of BXP 3.0 cracked version
A. Change the server name to "Dongan" and restart; This step can be placed before step 7;
B. Install the DHCP service program attached to Windows 2000 Server/Server 2003,
Run "PxeReg60.exe" or "DHCP 60 for xp.exe" to serve DHCP.
Add setting 60 option; Add a scope and enable it; If your system is Windows.

The file system32\Mylicense.dll cannot be overwritten;
G. Open My Computer, right-click My License and select.
Import License was imported into DongAn.vlf file and registered successfully;
When performing this step, you must ensure that the computer name is Dong 'an;
H. If you like, you can change the name of the server back to the name you want and restart the computer;
1. Run "BXP_RS". EXE "to restore the original license. When performing this step, make sure that all related services of BXP are not started, and that other programs have not been run after the system is started, especially the "My Computer" directory cannot be opened, otherwise the file System32 will not be overwritten \ Mylicense.dll may not perform this step;
1. Double-click the self-extracting installation file of BXP to start the installation. The welcome installation interface of "Wele" appears.
2. If you need to consult the English installation documents of BXP, you can click the "View" button; If no consultation is needed, click the "Install" button to start the installation.
3. After reading the product license agreement and agreeing, you can continue the installation. The next few steps can be set by default. When the Installation Type appears, select the first item, that is, Full Server.
4 Configure BXP server components
Configuring BXP server components includes the following:
Configure BXP related services
Configure DHCP service (if using local DHCP of BXP3.0)
Establish and manage BXP customer login
4. 1 Configure BXP related services
Before configuring the BXP server, you must ensure that the following service components are correctly installed on the server:
3Com BOOTP service or 3Com PXE service
BXP TFTP service company
BXP IO service
BXP login service
4. 1. 1. Selection of boot mode
BXP workstation has two boot modes, one is PXE mode and the other is BOOTP mode. PXE dynamically assigns IP addresses to workstations through DHCP service.
In the network structure of PXE, DHCP server and BXP server can be on the same computer.
In BOOTP boot mode, the IP address of the workstation is fixed, and each workstation must be manually specified on the server.
The startup mode of diskless system depends on different application environments. PXE mode is used for small and simple networks, and BOOTP mode is used for large networks, especially when multiple networks are mixed. The following settings are illustrated with PXE as an example.
4. 1.2. Configure PXE service.
On the server, open the control panel and double-click the icon "3 COM PXE". If a warning message appears, it means that PXE service has not started. Click Yes. If the built-in DHCP of Windows 2000 is installed, the system will prompt that DHCP is installed, and the built-in DHCP of BXP will be disabled. Click OK and the "3COM PXE" dialog box will appear. On the Options tab, in the Data File box, enter the BOOTPTAB file and its correct path, or browse to find the file. Because DHCP included with Windows 2000 is pre-installed, Proxy DHCP is not available. Click the "Neork Adapters" tab, select the IP address to be bound in the server IP address list, in this case,198.168.0.1,and then click "OK" to complete the PXE server setup.
3. Configure Ventura TFTP service.
Open the control panel of the server, double-click the Ventura TFTP service icon to open the TFTP setting dialog box, click the TFTP options tab, and set the path of the boot file Vldrmi 13.bin in the "Tran *** it (GET) directory" box. If BXP is installed in the default path during installation, the path of this file is c: \ program files \ ventur \ bxp \ tftpboot). After setting, click the "TFTP Neork" tab to bind the TFTP service to the relevant IP address, in this case, 198. 168.0.65438.
4. Configure BXP IO service
On the server, create a folder for storing all virtual disk image files, for example: D:\VLD. Please make sure that the disk where the folder is located has enough hard disk space. Click Start Menu → Select Program → Ventura BXP → BXP IO Service Preferences to open the BXP IO Service Preferences dialog box, and then click the browse button behind the virtual disk directory box. In the pop-up dialog box, select the folder D:\VLD that we created earlier to store the virtual disk image files. In the IP setting list, select "198.168.0.1",and other options can be set by default, as shown in figure 15. Finally, click "OK" to complete the configuration of BXP IO service.
5. Configure the BXP login service.
On the server, click Start Menu → Select Programs → Ventur Bxp → Bxp Login Service Preferences, and the Login Service Preferences dialog box will appear. Check whether the database path is determined (in C:\ Program file \Ventur\BXP\ VLD. MDB), and click the browse button to make a selection. Bind "198. 168.0.1"in the IP Settings list, and other options can be set according to the default values, as shown in figure16.
Click OK to complete the configuration of the login service.
If you use the built-in DHCP of BXP3.0, you need to use Start->; Program-> Bxp configuration wizard, after the configuration is completed, start the DHCPdNT service in the service of the control panel.
The default lease period is 120 days, and the longest is 120 days. Examples are as follows:
Sub 10.0.0.0 subnet
Mask 255.0.0.0 subnet mask
Optional router 10.0.0.2 gateway
Range 10.0.0.20 IP allocation range
Range 10.0.0. 120
4.2 Start BXP related services
Open the control panel of the server, double-click the management tool icon, open the management tool window, and double-click the service icon to open the service dialog box. Start the services in the following order and set them to run automatically.
3Com BOOTP or 3Com PXE
BXP TFTP service company
BXP adaptive boot server (this service does not need to be configured)
BXP IO service
BXP login service
BXP write cache I/O server (no need to configure this service)
4.3 Configure DHCP service
If the native DHCP of Windows 2000 system is used, the method of configuring DHCP service is exactly the same as PXE diskless Windows 98. See Chapter 7 of this series for details. If the server uses an operating system without DHCP, such as Windows XP of Windows 2000 workstation, you can set the DHCP of BXP to complete the PXE startup process.
5 Configure the BXP hypervisor
5. 1 management plan overview
BXP hypervisor has the functions of managing IO server, workstation account, virtual disk and configuring startup file path. Any modification to the data by using the management program is stored in the BXP database (VLD). MDB)。
Click the Start menu → Programs → Ventura BXP→BXP Administrator to open the BXP Manager. When all servers of BXP are started,
Because no workstation account, virtual disk and IO server have been established, there is only one icon for logging in to the server in the list, and subsequent chapters will appear in the list after being set.
5.2 Use of Management Procedures
1. 1. Configure the boot file.
Click Start Menu → Programs → Ventura BXP→BXP Administrator to open the BXP Manager. Click the Tools menu and choose the Configure Boot command. In the Path box, enter the boot file and its path, or click the Browse button to find the file in the Open window. By default, the boot file is: c: \ program files \ ventur \ bxp \ tftpboot \ vldbim650. Other options are set by default.
What is the performance of the extremely unstable network server? If the business volume is not large, the configuration of the machine should be enough now.
So it's not necessarily the hardware, but the application itself. This program is poorly written and unstable.
Hello! I have studied network technology systematically, and I hope it will help you.
First of all, the network server is essentially a computer, but its function is much more powerful than our general computer. For example, it is good that our computer CPU has four cores, but the CPU of the server does not need Pentium or Core, but uses four sets of 64-bit An Teng quad-core Xeon CPUs. Pay attention to four groups of Xeon quad-cores! It is equivalent to the most powerful 32 CPUs we often use. Of course, we can also use our general-purpose computer as the server when the requirements for the server are not high, that is, there is not much data to be processed or stored.
Its hard disk is also scary, and people use TB instead of GB.
There are many kinds of network services, such as blade, rack and so on.
It is so powerful because it has to save a lot of data, such as our QQ space. These data are not on the network, but on the server, and the server is used to save these data. Including all the web pages you have visited and downloaded data, the data source is on the server. So there are many servers, and larger organizations will have their own servers.
After connecting to the Internet, you can * * * enjoy resources!
I don't know if I speak well. Ha ha!
How about the red domain network server? Is the red domain network server fast? Is the red domain network server stable? Personally, I feel that the red domain network virtual host is not bad! Come on! Steady! Especially the service attitude, I am very satisfied!
Open and operate the network server. Well, that's not bad either.
Now there are many friends in the network, and the space used is not much. It is not enough to buy a server by yourself. And you can do such a business, you buy the whole server, and then retail the space of your server, and get rich profits from it. So you just stay at home, but you are actually in business, hehe, good.
I'm happy to answer your question. Please contact me if you need to rent a server. Haiteng data.-captain.
What is a network server? Computer network server
A server refers to a computer that manages resources and provides services to users. It is usually divided into file servers, database servers and application servers. The computer or computer system running the above software is also called a server. Compared with ordinary PC, the server requires higher stability, security and performance, so the CPU, chipset, memory, disk system, network and other hardware are different from ordinary PC.
For example, we open Baidu. At this time, you either open Baidu company or open something else. It is a file on Baidu server. The server is a network service. Servers can do many things.
Opening a web page is the protocol of the server (the protocol can be understood as the service type).
File transfer is the ftp protocol of the server.
Sending and receiving emails are *** tp and pop3 protocols.
Generally speaking, if you are not a professional. You can think of it as a computer serving tourists.
