1. NXD 98 / me system is based on PXE boot mode and disk image and disk snapshot technology, which is a set of system to realize network centralized storage of computers without hard disk and other local storage devices in the network based on remote boot and high-speed LAN. Netcom NXD is a bit similar to the traditional diskless network system, but different from the traditional diskless network system. NXD clients also have no hard disk, but through Netcom's proprietary technology, every client seems to have a real hard disk after it starts up, and each client can read and write, format, partition or ghost its own hard disk. So the concept of NXD, literally, is a system in which all computers in the LAN share the same hard disk.
2. Nxd7.0 diskless system fully introces Windows 7 client support, and adds a large number of Windows 7 client optimization, network management, Internet bar technician, Internet bar maintenance team make money: - - (here we recommend you use the Internet bar value-added service of [5636 Internet bar value-added platform])
3. It is understood that from the perspective of China's Internet cafes diskless instry, the three most recognized Internet cafes diskless are Ruiqi XP, Zhiming diskless and webmaster NXD. Of course, in addition to these three strong brands, dol, BXP, Qidong Ruiteng and other brands also have certain influence, but they all have their own limitations, and their popularity rate is relatively lower than the recognized three strong brands. So now the Internet bar diskless system which is better to use
the NXD diskless system is developed by Shanghai wangzhong Information Technology Co., Ltd. It mainly focuses on the northern market, with small and medium-sized Internet cafes as its main customer group. It charges for one-time, and has moderate price and a small amount of piracy. The point is that it is not comprehensive enough to meet the needs. It has to be said that netherworld is famous for its poor service
Ruiqi no Ruiqi no disk XP is developed by Shanghai Ruiqi Information Technology Co., Ltd. It is distributed all over the country. There are a lot of pirated procts. If the pirated procts are not included, the small Internet cafes are the main customer group, with one-time charges. The genuine price is higher, and the pirated procts are cheaper. The point is that piracy is rampant. Legitimate services are OK, but most of them are pirated and there is no follow-up service
spring mzd diskless system is developed by Hunan spring technology and Trade Development Co., Ltd. It mainly focuses on the central China market, with large and medium-sized Internet cafes as the main customer group. It charges by point according to the number of working platforms, with high price and no piracy. Of course, the more people use it, the more pirated it will be. If no one uses it, probably no one will crack it!

6. Netzon nxd6.0 diskless system, in terms of server load control, is as follows:
the load control of diskless server has always been the key research and development object of diskless software. Netzon nxd6.0 diskless system greatly reces the load pressure of server through innovative multi-directional caching mechanism, thus creating a new height of diskless server performance
nxd6.0 controls server load from two aspects: server cache and load factor. Due to the increasing capacity of the game board, the capacity of SAS disk is not enough to be used as a game board; Netcom recommends using the SATA disk group [Linux soft / hard array] or [Netcom RAID1] as the game master. However, the life of SATA disk is relatively short compared with SAS, so how to rece the access of SATA disk determines the safe life cycle of a diskless system. Nxd6.0 has done detailed testing and fine-tuning in server cache and load factor control, and provided a better algorithm to extend the service life of server hard disk and guarantee the possibility of normal operation after some hard disks fail
I hope it can be helpful to you, and I hope you can choose netcrowd procts

Netzon NXD XP 6.0 diskless system has carried out in-depth development in ha, client cache, server load, disk rendancy, multi operating system support and the combination with netzon express. Closer to the needs of users, nxd6.0 will be the flagship of diskless system
I. proct specialty
(I) high availability
1) server ha (professional version of windows / Linux, Internet cafe version of Linux)
NXD 6.0 supports ha (commonly known as server hot standby) of IO server. Server hot standby is used when an IO server cannot provide service e to unknown reasons, and other IO servers directly take over the data access service of the active workstation. Ha used to only appear in NXD professional edition which pays more attention to data security, but now it is open in Internet bar edition; In the application of this function, there will be some loss of performance, because the Internet cafes pay more attention to the level of performance, so please choose to open it; Its advantage is that the active client does not need to be restarted and can continue to be used The recovery time is less than 5 seconds)
2) network card ha (professional version of windows / Linux, Internet cafe version of Linux)
NXD 6.0 supports multiple network card ha (commonly known as network card hot standby) in one server. Network card hot standby is used to automatically take over the data access service of the active workstation when any network card in a multi network card IO server fails to provide service e to unknown reasons (network cable interruption, crystal head damage, network card damage, etc.) The recovery time is less than 3 seconds)
3) disk ha (professional version of windows / Linux, Internet cafe version of Linux, suitable for building [rendant array])
NXD 6.0 supports disk ha (commonly known as disk hot standby) in a server. Disk hot standby is applied to an IO server for unknown reasons & lt; Rendant array & gt; When any of the rendant array member disks fails, the other disks in the rendant array automatically take over the data access service of the active workstation The failure recovery time is less than 5 seconds)
the application of [rendant array] introced in NXD 6.0 is the situation that large capacity SATA disks are easy to be damaged, and [rendant array] provides mirror level data security guarantee on the basis of ensuring disk performance Please read the manual for the construction and reconstruction of [rendant array]
through the implementation of HA at the three levels of server, network card and disk, the NXD 6.0 diskless system of Netcom has reached the unprecedented security level of the software platform. Wangzhong technology innovatively introces the HA function of enterprise application into the Internet bar instry, which sets a model for the safety standard of diskless system in Internet bar
(2) server load control
the load control of diskless server has always been the key research and development object of diskless software. Netzon NXD 6.0 diskless system greatly reces the load pressure of server through innovative multi-directional caching mechanism, thus creating a new height of diskless server performance
NXD 6.0 controls server load from two aspects: server cache and load factor. Due to the increasing capacity of the game board, the capacity of SAS disk is not enough to be used as a game board; Netcom recommends using the SATA disk group [Linux soft / hard array] or [Netcom RAID1] as the game master. However, the life of SATA disk is relatively short compared with SAS, so how to rece the access of SATA disk determines the safe life cycle of a diskless system. NXD 6.0 has done a detailed test and fine-tuning in the server cache and load factor control, providing a better algorithm to extend the service life of the server hard disk and the possibility of normal operation of Internet cafes after the failure of some hard disks
1) accurate server cache (professional version of windows / Linux, Internet cafe version of Linux)
[Note: the server cache needs [xinhaoxiang 3C authentication server] to open, otherwise the hit rate will be 0]
NXD 6.0 server fine tuned the disk cache technology, further improved the cache optimization algorithm. It is stipulated in NXD 5.8 to use dynamic memory= 1g, cache boot partition recommended); NXD 6.0 removes the 1g limit, so you can set a large enough cache in the range of physical memory. By increasing the cache size of the server to the whole disk (such as setting 2-4G disk cache), the load of the server can be greatly reced. Some servers with 100% CPU utilization can effectively rece the CPU utilization through this setting Caching the entire image can effectively rece the server load, but if it is used together with layer 3 Update / express, the updated game may not appear on the client machine in time e to caching.)
2) load factor control (professional version of windows / Linux, Internet cafe version of Linux)
at the bottom of Figure 1, you can see that there is "maximum disk concurrent task number control", NXD 6.0 recommends "custom maximum disk development task number" as 1 / 4 ~ 1 / 3 of the number of loaded workstations. This function allows small Internet cafes to use cheaper servers to undertake diskless IO servers. Through this function, the low configuration server of wangzhong Haoxiang can greatly increase the number of machines
[Note: for low configuration servers, the maximum number of disk concurrent tasks can be reced to 1< (3) client zero write back (professional version of windows / Linux, Internet cafe version of Linux)
the large number of write back of diskless client to diskless server will make the server write frequently, and then increase the load pressure of the server. Because the disk bottleneck of diskless server is more and more inclined to write back disk, netzon technology in NXD 6.0 diskless system has revolutionized the client zero write back mechanism. By redesigning the client cache mechanism, diskless client can not write to the server hard disk for as long as possible, so as to most effectively rece the server pressure. In NXD 6.0, there is no waiting time for HA operation in zero write back state of diskless client. That is to say, it is possible to switch the server repeatedly if the client does not write back
the disk reading and writing performance of NXD 6.0 diskless client (that is, the network utilization of diskless client) has been further improved. Under the basic installation, the client can achieve the disk reading and writing performance of 100-110m / s, which has reached the transmission limit of gigabit network
the client cache of Netcom NXD 6.0 diskless system includes the following aspects:
1) s disk cache
Netcom's unique s disk implements write back cache in NXD 6.0. According to the test, set to 128M can effectively control s disk write back
2) client read / write cache
NXD 6.0 server provides the overall control of the size of client read / write cache, which is more simple and clear compared with the operation in previous versions. The new cache algorithm makes the client cache scope break through the limitation of the operating system, makes its performance fully play, greatly reces the read-write pressure of the server, extends the service life of the hard disk, and improves the entire network environment
3) NXD 6.0 client cache:
A) arbitrarily adjust the cache size (physical memory size limit)
b) make full use of the memory space that cannot be recognized when the memory of Windows XP exceeds 3.25G
4) client read / write cache and s disk setting reference
recommended setting 1: (use memory not recognized by Windows XP, 6g)
NXD 6.0 allows users to make use of physical memory beyond the scope of Windows XP, for example: a client has 6G memory, XP recognizes 3.25G memory (netcrowd testing machine), In addition, about 2.75g of memory is not managed by the operating system. However, NXD 6.0 client cache can use the 2.75g memory, so we set the s disk cache to 768m and the client cache to 2048m Using netcrowd platform, you won't waste every cent you spend!)
recommended setting 2: (use memory not recognized by Windows XP + memory managed by Windows XP, 4G)
a client has 4G memory, XP recognizes 3.25G memory (netcrowd test machine), and there is about 768m memory that cannot be managed by the operating system. We set the s disk cache to 768m and the client cache to 1024m
recommended setting 3: (full use of memory managed by Windows XP, 2G)
a client has 2G memory. We set the s disk cache to 256M and the client cache to 512M
recommended setting 4: (full use of the memory managed by Windows XP, 1g)
a client has 1g of memory. We set the s disk cache to 128M and the client cache to 128M
recommended setting 5: (full use of memory managed by Windows XP, 512M)
a client has 512M memory, we do not set s disk cache, set client cache to 64M
through the actual test, NXD 6.0 can maintain the client zero write back state for 2-3 hours under normal use when opening 128M s disk cache and 128M client cache< (4) support for multiple operating systems
1) NXD 6.0 Internet cafe version
NXD 6.0 Internet cafe version can be installed on netzone Enterprise Linux server (other Linux servers are supported in principle)
NXD 6.0 Internet cafe client supports DOS / Windows 2000 / Windows XP
2) NXD 6.0 Professional Edition
NXD 6.0 professional edition can be installed on Windows 2000 / Windows 2000 Server / Windows XP / Windows 2003 server / netzone Enterprise Linux server Note: other Linux is supported in principle)
NXD 6.0 professional client supports DOS / Windows 2000 / Windows XP / Windows Vista / Linux< (5) seamless integration with netcrow express
netcrow NXD 6.0 diskless system fully integrates all client functions (menu interface, asset management, information statistics, etc.) of netcrow express, seamlessly integrates with netcrow express server and automatic update function, and the mode of Internet bar installation, debugging and maintenance will be completely changed. The dream of once installation, all in place and never maintenance of Internet bar maintenance personnel will be realized.

NXD 6.0 has done a detailed test and fine-tuning in the server cache and load factor control, providing a better algorithm to extend the service life of the server hard disk and the possibility of normal operation of Internet cafes after the failure of some hard disks
1) accurate server cache (professional version of windows / Linux, Internet cafe version of Linux)
[Note: the server cache needs [xinhaoxiang 3C authentication server] to open, otherwise the hit rate will be 0]
NXD 6.0 server fine tuned the disk cache technology, further improved the cache optimization algorithm. It is stipulated in NXD 5.8 to use dynamic memory= 1g, cache boot partition recommended); NXD 6.0 removes the 1g limit, so you can set a large enough cache in the range of physical memory. By increasing the cache size of the server to the whole disk (such as setting 2-4G disk cache), the load of the server can be greatly reced. Some servers with 100% CPU utilization can effectively rece the CPU utilization through this setting Caching the entire image can effectively rece the server load, but if it is used together with layer 3 Update / express, the updated game may not appear on the client machine in time e to caching.)
2) load factor control (professional version of windows / Linux, Internet cafe version of Linux)
at the bottom of Figure 1, you can see that there is "maximum disk concurrent task number control", NXD 6.0 recommends "custom maximum disk development task number" as 1 / 4 ~ 1 / 3 of the number of loaded workstations. This function allows small Internet cafes to use cheaper servers to undertake diskless IO servers. Through this function, the low configuration server of wangzhong Haoxiang can greatly increase the number of machines
[Note: for low configuration servers, the maximum number of disk concurrent tasks can be reced to 1< (3) client zero write back (professional version of windows / Linux, Internet cafe version of Linux)
the large number of write back of diskless client to diskless server will make the server write frequently, and then increase the load pressure of the server. Because the disk bottleneck of diskless server is more and more inclined to write back disk, netzon technology in NXD 6.0 diskless system has revolutionized the client zero write back mechanism. By redesigning the client cache mechanism, diskless client can not write to the server hard disk for as long as possible, so as to most effectively rece the server pressure. In NXD 6.0, there is no waiting time for HA operation in zero write back state of diskless client. That is to say, it is possible to switch the server repeatedly if the client does not write back
the disk reading and writing performance of NXD 6.0 diskless client (that is, the network utilization of diskless client) has been further improved. Under the basic installation, the client can achieve the disk reading and writing performance of 100-110m / s, which has reached the transmission limit of gigabit network
the client cache of Netcom NXD 6.0 diskless system includes the following aspects:
1) s disk cache
Netcom's unique s disk implements write back cache in NXD 6.0. According to the test, set to 128M can effectively control s disk write back
2) client read / write cache
NXD 6.0 server provides the overall control of the size of client read / write cache, which is more simple and clear compared with the operation in previous versions. The new cache algorithm makes the client cache scope break through the limitation of the operating system, makes its performance fully play, greatly reces the read-write pressure of the server, extends the service life of the hard disk, and improves the entire network environment
3) NXD 6.0 client cache:
A) arbitrarily adjust the cache size (physical memory size limit)
b) make full use of the memory space that cannot be recognized when the memory of Windows XP exceeds 3.25G
4) client read / write cache and s disk setting reference
recommended setting 1: (use memory not recognized by Windows XP, 6g)
NXD 6.0 allows users to make use of physical memory beyond the scope of Windows XP, for example: a client has 6G memory, XP recognizes 3.25G memory (netcrowd testing machine), In addition, about 2.75g of memory is not managed by the operating system. However, NXD 6.0 client cache can use the 2.75g memory, so we set the s disk cache to 768m and the client cache to 2048m Using netcrowd platform, you won't waste every cent you spend!)
recommended setting 2: (use memory not recognized by Windows XP + memory managed by Windows XP, 4G)
a client has 4G memory, XP recognizes 3.25G memory (netcrowd test machine), and there is about 768m memory that cannot be managed by the operating system. We set the s disk cache to 768m and the client cache to 1024m
recommended setting 3: (full use of memory managed by Windows XP, 2G)
a client has 2G memory. We set the s disk cache to 256M and the client cache to 512M
recommended setting 4: (full use of the memory managed by Windows XP, 1g)
a client has 1g of memory. We set the s disk cache to 128M and the client cache to 128M
recommended setting 5: (full use of memory managed by Windows XP, 512M)
a client has 512M memory, we do not set s disk cache, set client cache to 64M
through the actual test, NXD 6.0 can maintain the client zero write back state for 2-3 hours under normal use when opening 128M s disk cache and 128M client cache< (4) support for multiple operating systems
1) NXD 6.0 Internet cafe version
NXD 6.0 Internet cafe version can be installed on netzone Enterprise Linux server (other Linux servers are supported in principle)
NXD 6.0 Internet cafe client supports DOS / Windows 2000 / Windows XP
2) NXD 6.0 Professional Edition
NXD 6.0 professional edition can be installed in Windows 2000 / Windows 2000 Server / Windows XP / W

one click automatic installation and recovery, as long as ordinary software is installed, Will install netherworld NXD
the server supports reading the hard disk directly. If you can install windows, you can do diskless
the server supports multi network card binding, and the network traffic is no longer the bottleneck
the server side supports multi server synchronization technology, and multiple servers can complete the update and maintenance at one time.
Netcom pioneered the single image online update technology, which enables the whole network system to update the disk under normal operation
provide timely update technology to experience the updated effect immediately
providing disk update point and restore point is equivalent to adding two safety locks to the system
each client has the function of synchronization, and additional disks of any size can be set for personalized storage
the server can be Linux system, which fundamentally stops the spread of most viruses
using disk snapshot technology, the virus file exists in the client, and it also exists as an ordinary data file, which cannot be spread
the client can control the image file or disk of the server, and achieve the function of full protection according to the requirements and settings
the server can control the peripherals of one or several diskless workstations. For example, close USB port, 1394 port, etc< As far as I know, Shanghai wangzhong has become a professional provider of diskless system, diskless terminal, network hard disk and other procts
in fact, the performance of every diskless software will not be much different
mainly depends on the technical ability of the construction person
the NXD XP 6.0 diskless system of wangzhong gathers the most cutting-edge, practical, practical and practical software in today's diskless field With the most market-oriented features, netzon NXD XP 6.0 diskless system has been deeply developed in ha, client cache, server load, disk rendancy, multi operating system support and the combination with netzon express. Closer to the needs of users, nxd6.0 will be the flagship of diskless system
I. proct specialty
(I) high availability
1) server ha (professional version of windows / Linux, Internet cafe version of Linux)
NXD 6.0 supports ha (commonly known as server hot standby) of IO server. Server hot standby is used when an IO server cannot provide service e to unknown reasons, and other IO servers directly take over the data access service of the active workstation. Ha used to only appear in NXD professional edition which pays more attention to data security, but now it is open in Internet bar edition; In the application of this function, there will be some loss of performance, because the Internet cafes pay more attention to the level of performance, so please choose to open it; Its advantage is that the active client does not need to be restarted and can continue to be used The recovery time is less than 5 seconds)
2) network card ha (professional version of windows / Linux, Internet cafe version of Linux)
NXD 6.0 supports multiple network card ha (commonly known as network card hot standby) in one server. Network card hot standby is used to automatically take over the data access service of the active workstation when any network card in a multi network card IO server fails to provide service e to unknown reasons (network cable interruption, crystal head damage, network card damage, etc.) The recovery time is less than 3 seconds)
3) disk ha (professional version of windows / Linux, Internet cafe version of Linux, suitable for building [rendant array])
NXD 6.0 supports disk ha (commonly known as disk hot standby) in a server. Disk hot standby is applied to an IO server for unknown reasons & lt; Rendant array & gt; When any of the rendant array member disks fails, the other disks in the rendant array automatically take over the data access service of the active workstation The failure recovery time is less than 5 seconds)
the application of [rendant array] introced in NXD 6.0 is the situation that large capacity SATA disks are easy to be damaged, and [rendant array] provides mirror level data security guarantee on the basis of ensuring disk performance Please read the manual for the construction and reconstruction of [rendant array]
through the implementation of HA at the three levels of server, network card and disk, the NXD 6.0 diskless system of Netcom has reached the unprecedented security level of the software platform. Wangzhong technology innovatively introces the HA function of enterprise application into the Internet bar instry, which sets a model for the safety standard of diskless system in Internet bar
(2) server load control
the load control of diskless server has always been the key research and development object of diskless software. Netzon NXD 6.0 diskless system greatly reces the load pressure of server through innovative multi-directional caching mechanism, thus creating a new height of diskless server performance
NXD 6.0 controls server load from two aspects: server cache and load factor. Due to the increasing capacity of the game board, the capacity of SAS disk is not enough to be used as a game board; Netcom recommends using the SATA disk group [Linux soft / hard array] or [Netcom RAID1] as the game master. However, the life of SATA disk is relatively short compared with SAS, so how to rece the access of SATA disk determines the safe life cycle of a diskless system. NXD 6.0 has done a detailed test and fine-tuning in the server cache and load factor control, providing a better algorithm to extend the service life of the server hard disk and the possibility of normal operation of Internet cafes after the failure of some hard disks

netherworld's support for Linux and windows al platform is its feature, but it is a double-edged sword. The low popularity of Linux affects its maintenance and technical services
Ruiqi does have its own unique features, and the ISV qualifications of Intel and Microsoft are not in vain. However, the rise of pirated procts is more than genuine ones, which is really embarrassing
many of mzd's unique technical designs are also tailored for the LAN of large and medium-sized Internet cafes, such as multi server mutual backup, VIP user design, game archiving remote call, etc. only in large and medium-sized Internet cafes can they be used. In addition, its mzd BT intelligent game update platform should be the best update platform in diskless world. However, the technical service maintenance system needs to be strengthened in order to meet its high-end positioning strategy
IT technology is changing with each passing day, and the market of Internet bar diskless instry is also changing rapidly. The competition among the top three diskless companies, such as NXD, Ruiqi XP and spring mzd, will only become more and more fierce. What will be the future diskless pattern? Is it a single family, a confrontation between two heroes, a tripartite confrontation, or a dispute among the heroes? Let's wait and see, look forward to China's Internet bar diskless instry flying higher and higher, better tomorrow!
