Description

A SAS 12G RAID memory card

technical field

The utility model relates to a RAID storage card, which belongs to the field of server data storage equipment, in particular to a SAS 12G RAID storage card.

Background technique

With the rapid development of computer technology, the importance of various information data is becoming more and more obvious. Data storage protection is one of the technologies prioritized by server manufacturers. Data storage protection is mainly implemented by backing up the data on the current disk with various algorithms to prevent sudden disk damage, or data inaccessibility due to various other reasons, or part of the data has been damaged. The backed up data can be restored to the production disk in the first time after the data fails, so as to minimize the loss to the greatest extent.

RAID (Redundant Array of Independent Disks) is a redundant array of independent disks, which is the main technology for data storage backup. RAID technology combines multiple individual physical disks into a logical disk in different ways, thereby improving the read-write performance and data security of the disk. According to different algorithms, it can be divided into different RAID levels: Raid0/1/2/3/4/5/6. At the same time, two different RAID methods can be combined into a new RAID level, such as Raid10/50/60, in order to meet the needs of disk capacity, data redundancy, or storage system performance. According to the above technology, the utility model designs a SAS 12G RAID memory card, which has the advantages of good compatibility and fast data transmission.
