Today, I will talk to you about what the requirements of RAID on the server are, many people may not know much about it. In order to make you understand better, the editor summarizes the following content for you. I hope you can get something according to this article.

What are the server requirements of RAID? RAID technology is not only widely used in the server, but also widely used in IT and other aspects. The server has a very wide range of applications for many technologies. Here, I will introduce the requirements of RAID to the server.

Because RAID technology can make multiple disks read and write at the same time, this makes the performance requirements of CPU, memory and Icano bandwidth of the server much higher than that of a single disk, and the read and write performance of a single disk is getting higher and higher, so the above requirements for the server are higher and higher. In the past, when using Ultra Wide SCSI,40Mbps disk arrays, the speed of CPU was not strict, because SCSI itself was not very fast. But when SCSI evolved into Ultra,80Mbps, the requirements for CPU became stringent-at least on Intel Pentium processors, and on dedicated processors for high-performance servers based on the RISC architectures of companies such as IBM, HP, Compaq and Sun. Now, the latest processors such as Intel and AMO can support the fastest RAID technology of Ultra 3320Mbps.

In addition, server bus technology is also an important factor restricting the application of RAID. Therefore, the structure of the server Imaco bus supporting RAID technology has been changed from the traditional Icano structure to the 12O (IntelligentI/O, abbreviated to 12O, intelligent iMab O) structure. Its purpose is to reduce the burden of the server CPU and separate the system's iMab O load from the server CPU load.

In terms of server network operating systems, NetWare systems currently support RAID1 (mirroring and duplex). Windows NT, Windows 2000, Linux and other systems all support RAIDO, RAID1, and RAID5 levels.

In order to achieve data security redundancy, there must be certain requirements for the use of disks in the disk array. How to ensure the security of data depends on the design and quality of disk array. There are several functions that must be considered: whether there is an environmental monitor for temperature, voltage, power supply, cooling fan, disk status and so on.

After reading the above, do you have any further understanding of RAID's requirements for the server? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
