For upper-layer write IO, there are two modes for RAID controllers:

(1) WriteBack mode: When data arrives from the upper layer, the RAID controller saves it to the cache and immediately notifies the host IO is complete. This allows the host to proceed to the next IO without waiting, while the data remains in the RAID card's cache without being written to the disk. The RAID controller optimizes the disk writes by either writing to the disk individually, in batches, or queuing the IOs using queueing techniques. However, this approach has a critical drawback: if a power outage occurs, the data in the RAID card's cache is lost while the host assumes the IO is completed, resulting in significant inconsistencies between the upper and lower layers. Hence, certain critical applications, such as databases, implement their own consistency detection measures.

Due to this reason, high-end RAID cards require batteries to protect the cache. In the event of a power outage, the battery continues to supply power to the cache, ensuring data integrity. Upon power restoration, the RAID card prioritizes writing the incomplete IOs stored in the cache to the disk.

(2) WriteThrough mode: In this mode, IO from the upper layer is only considered complete after the RAID controller writes the data to the disk. This approach guarantees high reliability. Although the cache's performance advantage is lost in this mode, its buffering function remains effective.

In addition to being a write cache, read cache is also very important. The cache algorithm is a very complex subject, with a set of complex mechanisms. One of the algorithms is called PreFetch, which means that the data on the disk that is "likely" to be accessed by the host next time is "read into the cache" before the host issues a read I0 request. How is this "likely" calculated?

In fact, it is assumed that the host has a high probability of reading the data in the adjacent position of the disk where the data read this time is located in the next IO. This assumption is very applicable to continuous IO sequential reading, such as reading logically continuous stored data. Such applications, such as FTP large file transfer services and video on demand services, are all applications for reading large files. If many fragmented small files are also stored continuously in adjacent positions on the disk, caching will greatly improve performance, because the IOPS required to read small files is very high. If there is no cache, it depends entirely on the head seek to complete each IO, which takes a long time.

A computer is like a biological brain. The brain uses eyes, ears, nose, and skin as input devices to obtain various information, while the computer uses keyboard, mouse, serial port, USB interface, etc. as input devices to obtain various information. The brain uses neural networks to transfer acquired information to the nerve center, while computers use various bus technologies to transfer information to the CPU for calculation.

The brain uses neural networks to transfer calculated information to "devices" such as arms, legs, muscles, etc.; and computers also use buses to transfer calculated data to external devices, such as monitors, printers, etc.

The human brain can store a variety of data, and computers can also use external media to store data. From this point of view, the computer itself is an external information storage and processing tool for the human brain.

The field of computer storage studies how to provide data to computers quickly and efficiently to assist in their operations. Like the history of human storage, computer storage technology has also continued to develop and grow, from early floppy disks and hard drives with only a few dozen megabytes in size to today's single hard drives with a size of 1TB, and USB flash drives with a capacity of 4GB or even 16GB.

In order to pursue high speed, people make multiple disks into a RAID (Redundant Arrays of Independent Disks) system, that is, each independent disk is formed into an array to jointly store data and speed up data storage.

While pursuing high speed, the capacity problem must also be solved. The storage capacity requirements of modern computer programs have become enormous.

The latest Windows Vista operating system takes up more than 6GB of disk space just after installation. Some large-scale 3D games require 2GB, 4GB, or even 8GB in size just to install the files. The database files generated by some database management programs may be several TB or even hundreds or thousands of TB in size. The traditional method of placing the hard disk in the computer chassis can no longer meet the storage capacity requirements of modern applications, which has given rise to network storage technology.

Network storage extends the storage system to the network, making the storage device a node on the network for access by other nodes. In this way, even if there is only one hard disk in the computer host, or even no hard disk, the computer can still access data on the storage device through the network. Currently, the hot technology in the field of computer storage is network storage technology, which focuses on how to provide data flow services to other nodes on the network. Based on network storage, many other related technologies can be promoted and applied.

It can be seen that the storage field is an all-encompassing field. If you do not understand computer systems, it is difficult to master storage technology.

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.

Understanding server raid cards

Raid card: The full name is Redundant Array of Independent Disks Card. It uses Raid technology to turn multiple hard disks into one logical disk, with better capacity, performance, reliability, and manageability

SAS card: It is positioned as a low-end hard disk array expansion card. Compared with Raid cards, it has obvious gaps in terms of no cache, Raid level 0, 1, and performance.

Onboard raid: refers to the SATA controller integrated in the PCH of the server motherboard, which usually only supports SATA disks, has no cache, poor performance, and has limitations.

The CPU of the RAID card implements the functions of the RAID card by executing the firmware in the flash memory to control the SCSI controller, CacheMemory, and the indication alarm circuit. The operation process is as follows:

1. Initialize the RAID card register

2. Read the last RAID parameters in NVRAM, compare with the actual hard disk information to display the results

3. Send configuration prompts, respond to HOST commands to enter the configuration interface

4. Provide a configuration menu, and store the RAID card parameters and RAID parameters provided by the user in NVRAM

5. According to the RAID parameters, initialize the hard disk write operation through the SCSI controller

6. Complete the configuration and wait for the Host to issue a read and write operation command
