Features of several commonly used raid

data protection and recovery capabilities, enablingRAID TenHas become a more cost-effective grade, almost all of the currentRAIDThis level is supported by the control card. However,RAID Tenutilization of storage capacity andRAID 1as low as only50%. Therefore,RAID10high reliability and efficient disk structure it is a band structure plus a mirror image structure, can achieve both efficient and high-speed purposes,RAID Tencan provide more thanRAID 5better performance. The scalability of this new structure is not good, the solution is widely used, the use of this scheme is more expensive.

RAID:RAID50is aRAID5with theRAID0the combination. It hasRAID 5and theRAID 0common characteristics. It consists of two groupsRAID 5disk composition (minimum per group3each group uses a distributed parity bit, and the two groups of hard disks are then assembled into aRAID 0, which enables data to be pumped across disks. RAIDprovides reliable data storage and excellent overall performance, and supports larger volume sizes. Even if two physical disks fail (one in each array), the data can be recovered smoothly.

RAID Minimum Required 6 drives, which are best suited for applications that require high reliability storage, high read speed, and high data transfer performance. These applications include transactional processing and Office applications that have many users accessing small files.

JBOD:JBODis a class of important storage devices in the storage domain. JBOD(Just a Bunch of Disks, a disk cluster) is a storage device with multiple disk drives installed on a backplane. Often referred to asSpan. and theRAIDarrays are different,JBODThere is no front-end logic to manage the distribution of data on the disk, instead, each disk is individually addressed as a separate storage resource, or based on part of the host software, orRAIDan adapter card for the group. JBODnot standard.RAIDlevel, it has only been introduced in recent years by some manufacturers, and is widely used.

jbod with raid jbod often installed in 19 TB The disk is established jbod configuration becomes possible.

in jbod jbod recovery capability in the event of a separate disk failure, without proper circuitous capabilities, A failure of one drive could result in the entire jbod the failure.

JBOD the array of disks in the system has strict refrigeration and power supply facilities, which are the important embodiment of fault tolerance. Fault tolerance for power supplies, cooling systems, data buses, and other components helps the data storage system recover errors caused by hardware corruption, but it does not help to check and fix errors. In theory,theJBOD solution should be in the management state by sending standard information to the alert software to inform managers of current data issues.

becauseJBODgenerally in the use of a number of disks, so the total storage capacity is very large, and if a disk failure will cause the failure of the entire device, it is bound to the system is a huge risk. One of the solutions is softwareRAID. From the host side, the adoption of softwareRAIDand theJBODthe combination of hardware andRAIDThere is no logical difference, just the softwareRAIDconsumes a portion of the host resource, and the hardwareRAIDnot reach the demanding requirements of high-performance systems.
