RAID 5 is a redundant array of independent disks configured using disk striping with parity. Data and parity are striped evenly across all disks. Striping allows users to rebuild data in the event of a disk failure, so no one disk is the bottleneck.   RAID 5 balances reading and writing and is currently one of the most commonly used RAID methods. It has more storage space available than RAID 1 and RAID 10 configurations and provides performance comparable to RAID 0.   A RAID 5 group has a minimum of 3 HDDs, but no maximum. Because parity data is distributed across all drives, RAID 5 is considered one of the most secure RAID configurations.   RAID 5 – Stripes data using distributed parity. RAID type 5 allows Clariion to distribute parity information to reconstruct a failed disk among the disks that make up the RAID group. As with RAID 3, if a single drive in the RAID group fails, the failed disk can be rebuilt from the remaining disks in the RAID group.     How RAID 5 works The advantage of RAID 5 comes primarily from its combined use of disk striping and parity. Striping is the process of storing contiguous segments of data across different storage devices; it allows for better throughput and performance. However, disk striping alone does not make an array fault tolerant. Disk striping combined with parity provides RAID 5 with redundancy and reliability.   RAID 5 uses parity instead of mirroring for data redundancy. When data is written to a RAID 5 drive, parity is calculated and written to the drive. While mirroring maintains multiple copies of the data in each volume for use in the event of a failure, RAID 5 can rebuild a failed drive using parity data, which is not saved on a fixed single drive.   By saving data on each drive, any two drives can be combined to equal the data stored on a third drive, keeping data safe in the event of a single drive failure. Drives in RAID 5 are hot-swappable, meaning a failed HDD can be removed and replaced without downtime.   STOR Technology Limited provides you with high-quality Raid Card, HBA Card, Hard Disk Drive, etc. such as: lsi megaraid 9460 8i, 05 50077 00 9560-16i, 05 25528 04 9380-8e. We provide you with higher-quality services and assured after-sales service.

RAID, which stands for Redundant Array of Independent Disks, is also known as “disk array”. It is essentially a system that forms a large disk by combining multiple independent disks together, thereby achieving better storage performance and higher reliability than a single disk. Here are some common types of RAID:   RAID 0: Combines multiple disks to form a large storage capacity. When we need to write data, the data is divided into N parts, and N disks are read and written in an independent manner. These N parts of data are written to the disk concurrently, so the execution performance is very high.   RAID 1: When writing data to the disk, the same data is written to two disks without distinction, which are written to the working disk and the mirror disk respectively. Therefore, its actual space usage rate is only 50%, and two disks are used as one, which is a relatively expensive solution.   RAID 5: This is currently the most used method. Because RAID 5 is a solution that takes into account storage performance, data security, and storage cost.   RAID 6: In order to further improve the high availability of storage, people have proposed the RAID 6 scheme, which can also guarantee data recovery when two disks are damaged at the same time.   RAID 10: RAID 10 is a combination of RAID 1 and RAID 0.   Each type of RAID has its specific application scenarios. Which type to choose depends on your specific needs, such as data security, read and write speed, storage space, etc.   Among them, megaraid 9560 8i and megaraid 9560 16i are highly used RAID adapter. It is based on SAS3908 high-port-count PCIe 4.0 x8 RAID-on-Chip (RoC), and its performance is twice that of previous generations of products. 9560-8i has Tri-Mode SerDes technology, which allows NVMe, SAS, or SATA devices to run in a single drive bay, thereby achieving endless design flexibility.

Today we are going to talk about RAID implementation and configuration in the operating system. Some people write programs directly on the host, running at the bottom of the operating system, the physical disk submitted from the host SCSI or IDE controller, using the idea of seven stars Beidou, virtual into various modes of virtual disk, and then submitted to the upper program interface, such as volume management program. These programs use a configuration tool that lets you choose which disks to combine and form which type of RAID. For example, if two IDE disks and four SCSI disks are installed on a machine, the IDE hard disk is connected directly to the IDE interface integrated with the motherboard, and the SCSI disk is connected to a PCI interface SCSI card. In the absence of RAID program to participate in the conditions, the system can identify six disks, and after the file system format, mount to a disk letter or directory, for the program to read and write. After installing the RAID program, the user through the configuration interface, the first two IDE disks made a RAID 0 system. If the original IDE disk is 80GB, then RAID 0 will become a 160GB "virtual" disk. Then the user makes a RAID5 system with 4 SCSI disks. If the original SCSI disk capacity is 73GB, the capacity of the virtual disk after making the 4 disks into RAID5 will be about 3 disks, that is, 216GB. Of course, because the RAID program needs to use part of the disk space to store some RAID information, the actual capacity will be smaller. After being processed by the RAID program, these six magnets eventually become two virtual disks. If you are on the Widows system, opening Disk Manager will only show you two hard drives, one with a capacity of 160GB (drive 1) and the other with a capacity of 219GB(drive 2). The disks can then be formatted, for example, to an NTFS filesystem. The formatter has no sense that more than one physical hard disk is writing data. For example, the formatter may at some point issue a command to write data from memory start address so and so to disk 1 (a RAID 0 virtual drive consisting of two IDE disks) at LBA start address 10000 and length 128. The RAID program will intercept this command and analyze it. Disk 1 is a RAID 0 system, so the data of 128 sectors starting from LBA10000 will be calculated by the RAID engine, and the logical LBA will be corresponding to the physical LBA of the physical disk, and the corresponding data will be written to the physical disk. Once written, the formatter receives a signal that the write was successful and moves on to the next IO. After this process, the upper layer is completely unaware of the details of the underlying physical disk. The same is true for other forms of RAID, but the algorithms are more complex. But even though the complex algorithm, after CPU operation, it is thousands of times faster than the disk read and write speed. Tips: To ensure performance, only the same type of disk can be used for the same disk group, although it can also be designed to IDE magnetic Disk and SCSI disk are combined to form a virtual disk, but it is not designed this way unless specifically required.
