Introduction to RAID 5

Defining a RAID 5 array

This wide array of uses at least three plates and strip byte-level information about the partitions. parity data about each member of the disc, so that the data array in the event of a disk failure can be restored.

Different ways for a RAID 5 array can be set

A RAID 5 array can be set up as a software RAID using special software or hardware RAID with a RAID controller.

A softwareRAID is usually either put up with stand-alone software or with software RAID, which is an operating system like Windows 2003 server configured. A software RAID uses the CPU and the memory of the computer on which it is installed. This can slow down other applications on your computer. The software also RAID vulnerable to error because of problems with the host computer. A hardware RAID uses a RAID controller takes the place so as not to load on the host computerCPU and memory.

Top 5 Suitable for RAID applications

Since RAID 5 provides better read performance benefits in writing, it is better for read-oriented applications such as web, intranet and e-mail servers use. It could also be suitable for databases, provided that there is more reading than writing. In RAID 5 are listed, as the array must write the parity data on hard drives slow.

Advantages and disadvantages of RAID 5

E 'many advantages of a RAID 5 array. Given a set of RAID-5 parity data written to each of the member drives, a RAID-5 Sustain the failure of a hard disk. The parity data allows the RAID to be restored. Another advantage of RAID 5 is that it is relatively cheap considering the amount of fault tolerance it provides. Finally, RAID 5 offers a good rate of State Disk readings. are some disadvantages of RAID 5 is that it offers slower writes parity data must also regularly reviewDate. It can also be expensive to implement because it requires special hardware.

Conclusion

Overall, RAID 5 offers excellent fault tolerance without wasting space. It also provides high read performance and is suitable for a variety of applications. For more information on RAID 5 array can be found in RAID-5 recovery.
