What are the different types of hard disk arrays for Internet cafe diskless systems?

1. Introduction to diskless network

What is a diskless network? In short, all the workstations in a network do not have hard disks installed, but are all started through the network server. Such a network is a diskless network, and these workstations are called diskless workstations. People who have never been exposed to diskless networks may quickly become interested in such a network. Each workstation saves a hard disk, and a network of thirty or forty machines saves a considerable amount of money. This may be for everyone. The first impression of someone new to diskless networking. Indeed, saving money is a major advantage of diskless networks, but in fact the main advantage of diskless networks is not saving money, but "management and maintenance." Administrators responsible for network management should have a deep understanding of "management and maintenance". The main job of a network administrator is to ensure that a network can operate normally. In an ordinary network with disks, such as a network classroom, if something goes wrong with the workstations in the network and cannot be turned on or connected to the Internet, or the software in the network needs to be upgraded, upgrade Office97 to Office2000. At this time, the network administrator will When he gets busy, he is responsible for adjusting each machine, installing new software, and even reformatting, partitioning, and installing the system on each machine's hard drive. Maybe it won't be long before the system is accidentally destroyed by students, so it will be tedious to install, debug, etc., which is not only troublesome, but also delays work and affects the normal use of users.

As a result, a new network structure: the diskless network emerged. The original intention of the diskless network is to reduce the cost of workstations, but it is mainly for the convenience of management and maintenance. Just imagine, if the operating system files and software files used by the workstation 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, and all computers in the network can use it. New software, this is indeed good news for network administrators. But in fact the situation is not that simple. The traditional diskless Window95 initially launched by Microsoft has caused people to lose confidence in "diskless networks". The cumbersome configuration of diskless networks is more troublesome and the structure is unreasonable than the configuration of disk-based networks. As a result, the traditional diskless network system is unstable, the software runs abnormally, and even many software cannot run. These make the diskless technology almost come to an end. It is at this time that the diskless Windows98 and Windows2000 terminal network systems came into being.

Scope of application

The diskless network system can be used in the establishment and transformation of network classrooms, corporate internal LANs, Internet cafes, hotels, karaoke entertainment industries and all diskless networks.

1. Suitable for the establishment or transformation of diskless network classrooms in schools

2. Suitable for large, medium and small 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

Diskless benefits:

Save money Each workstation does not use a hard disk, saving a lot of money. But this is not the main advantage of diskless.

The easy-to-manage workstation automatically restores in 10 seconds. Since there is no hard disk, there is no need to worry about random shutdown or human damage.

The speed is 12 seconds faster than entering WIN98, which is unimaginable with a disk. The server uses a high-speed disk array, coupled with large memory, large cache, and high-speed CPU, so the response speed is extremely high, which greatly improves the performance of ordinary workstations.

Rich content: Each workstation can enjoy 240G or more programs, 6 times more than a disk. More than 2,000 MP3s, more than 1,000 movie episodes, and 1,000 games are enough to make every Internet user happy and make Internet cafes rich.

The unique super protection function with good security is enough to put disk-based workstations to shame. It is not afraid of malicious attacks and destruction, and can achieve unattended and zero maintenance. You no longer have to ghost the hard drive all day long.

Quick game upgrade Upgrading server games is equivalent to upgrading games on hundreds of workstations at the same time.

The installation is quick and easy. The original network remains intact, and it only takes about 3 hours to convert 100 units to diskless equipment
