In this question, we need to have a certain understanding of RAID 5, SAS 24G array card, PCIe Switch and other concepts. RAID 5 is one of the disk array schemes that uses distributed error correction coding technology to realize data redundancy and backup. Raid 5 generally features high performance, high availability, and high reliability. SAS 24 Gbit/s array controller card is a type of disk array controller card that supports SAS or SATA ports. The SAS 24 Gbit/s array controller card improves disk read/write speed and improves the performance and reliability of the storage system. PCIe Switch is a switching device based on PCI Express technology. It converts PCI Express channels into other forms of communication interfaces, improving communication bandwidth and data transmission rate.   If a SAS 24G array card is embedded into a PCIe Switch, you can increase the data transmission bandwidth by adding circuit boards and channels. Therefore, in this case, the write bandwidth of RAID 5 can be increased to 11.7GB/s, that is, 11.7GB of data can be written per second. This data transmission rate is very fast, which can meet the requirements of large-scale data centers and high-performance computing applications.   Note that the actual bandwidth is limited by many factors, such as disk read/write speed, memory bandwidth, and system stability. Therefore, in practical applications, it is necessary to optimize and adjust the system according to the specific situation to improve the performance and reliability of the system.   There are several manufacturers in the market offering SAS 24G array cards embedded in PCIe Switch products, and different models vary in terms of features, performance, interfaces, and prices. The following are some common models that insert a SAS 24G array card into a PCIe Switch:   Microsemi Adaptec Series 8: This is a powerful SAS/SATA RAID controller card that can support up to 16 disk drives and connect it to the host via a PCIe Gen3 x8 interface. The card also has advanced RAID features such as online fault-tolerant recovery and flash write-back caching.   Broadcom MegaRAID SAS 9361-8i: This card is a SAS/SATA RAID controller card that supports up to 240 disk drives and connects it to the host via a PCIe Gen3 x8 port. The card also has advanced RAID functions, such as online expansion and RAID cascading.   Avago HBA 9400-16i: The Avago HBA is a high-end Host Bus Adapter (HBA) that supports up to 1024 devices and connects to the host through PCIe Gen3 x16 ports. The card also supports the NVMe protocol, which provides faster data transfer rates and low latency.   QLogic QLE8262-CU-CK: The card is a combination of a high-performance 10GbE network adapter and Fibre Channel over Ethernet (FCoE) controller. It supports PCIe Gen2 x8 interface connection and provides up to 20 Gbps of data bandwidth. It is suitable for high-performance computing and large-scale data centers.     The above are some common models that embed the SAS 24G array card into the PCIe Switch, but not all of them. Choosing the right product should be based on the specific application scenario and requirements.

  The RAID system is an effective means to protect data from stored data. In the RAID creation process, there is often a very long time system initialization process. Why is there such an operation in the RAID initialization process? What aspects will this operation have on SSD? Let's analyze and study the RAID initialization process from the perspective of technology development.   The basic organizational structure of a traditional RAID array is that all disks added to a RAID Group are divided into a series of slices based on their LBA addresses. These slices are called Stripe Units. Stripe units corresponding to the same LBA addresses on different disks are organized into a Stripe. Encoding all data in one strip, such as RAID6 producing two encoded data blocks P and Q, allows both data disks to be corrupted at the same time.   Therefore, in the RAID system, all the data in the strip need to meet the rules of coding and dec algorithm, that is, all the data in the strip can generate coding data according to certain rules, and the coding data is the same as the coding data stored in the strip. This situation is called the data in that band. When a disk fails, the lost data blocks can be recovered by the encoded data stored in the strip.   If the data in a strip is inconsistent, that is, the coding result obtained by the data in the strip is not the same, then once a disk fails, the missing data block cannot be properly recovered by the coded data stored in the strip. Therefore, a strip of data inconsistency that will cause data correctness issues when the fault occurs. When creating a RAID system, the disk in the RAID Group may be either a new disk or a data disk that has already been used, where all data will not be zero. In this case, the data strips constructed with these disks must not meet the need of data consistency. That is, the coding data in each band calculated according to certain rules is inconsistent with the coding data in the band. Such data-inconsistent bands will introduce a great risk to the problem of RAID data correctness.   For this reason, when creating a RAID, you need to consider initializing all the strips in the system to ensure the consistency of the data in the bands. Band initialization can usually be solved in two ways: 1. Initializes all the bands in the RAID system by writing the total zero. All data zero band, its check data is also zero. Therefore, all-zero data can guarantee band consistency. 2. Check all the strips and update the check data in the strips to achieve the consistency of the strip data.   When a RAID system is initialized, the data in all bands will become consistent.The RAID system initialization process is a very long process, mainly because the need to initialize all the bands in the system. The performance balance between the front-end user IO, so RAID system initialization is often a background execution process, which will last for a long time and affect the performance of front-end applications.   For SSDS, the RAID system initialization process also introduces other problems. During system initialization, data needs to be written to SSDS, no matter in zero write or parity data update mode. This process results in unnecessary data write enlargement. Before user data is written, a data mapping table is established inside the SSD through initialization. The service life and performance of SSDS are reduced. Therefore, a RAID system for SSDS needs to be optimized for the system initialization process, which is a special feature that traditional RAID does not take into account. Therefore, traditional RAID arrays cannot be directly deployed on SSDS, which affects SSD service life and performance.   RAID systems use striping to protect data, but a series of problems are also introduced in the process of striping data protection. System initialization is a typical problem of strip consistency. A good RAID Data protection system will solve this problem during the design process. For example, EMC Data Domain RAID does not have the system initialization process, of course, it needs to cooperate with the file system, and has done a lot of optimization in RAID strip data distribution.
