1、OCP stands for Open Compute Project, a non-profit organization initiated and founded by companies such as Facebook in 2011. Its aim is to reconstruct current data center hardware in an open-source and open manner, developing innovative hardware for next-generation data centers, including servers, storage, networking, infrastructure, and more. Its members include major scale internet enterprises like Google, Microsoft, Baidu, Tencent, Alibaba, as well as solution providers. Along with ODCC and OPEN19, it is recognized as one of the world's three major open compute organizations.   2、What is an OCP NIC? The OCP NIC is one of the most successful components within the OCP project, and currently, the OCP 3.0 has become a mainstream component for server vendors. Why are people willing to use OCP NICs? The reasons are summarized below: Standardization: It solves the compatibility issues caused by the varying forms of LOM cards from different manufacturers. Ease of use: It replaces traditional LOM NICs in terms of design, resulting in lower maintenance costs. Greater openness: It features fast technology updates, leading designs, and meets the requirements of data center applications. OCP NICs not only offer ease of maintenance but also provide a broader range of interface speeds.   3、Development history of OCP NICs The OCP NIC 3.0 can come in three different heights. The currently used 15.1mm height card is referred to as SFF (Small Form Factor), while the 17.8mm height card is known as TSFF (Tall Small Form Factor), and the even higher 20.1mm card is called ETSFF (Extra Tall Small Form Factor).   4、With the widespread use of PCIe Gen5 rates on the next-generation server CPUs starting from 2022, the x16 card interface will have no problem supporting 400G network bandwidth. To meet the future demand for 400G NICs, the OCP NIC group, following the principle of specification first, has started considering the feasibility of existing 15.1mm height NIC 3.0 cards for supporting 400G optical modules. Technologies continue to advance, leading to a more range of OCP NIC types.   STOR Technology Limited provides you with high-quality network card adapters such as X550-T2, MCX512A-ACAT, MCX4121A-ACAT, MCX4421A-ACAN, X520-DA2, and provides you with higher quality services and reliable after-sales services.

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.   STOR Technology Limited provides you with high-quality 9560-16I, 9560-8I, 9361-4I, 9540-8I, etc. We provide you with higher-quality services and assured after-sales service.

There is a close relationship between AI and network cards, and they play an important role in promoting the development of AI technology. A network card (Network Interface Card) is a hardware device in a computer that connects to the network and is responsible for transmitting data to the network. In AI applications, the network card plays the role of a bridge between the AI ​​system and the outside world.   First, the network card plays a key role in the AI ​​training and reasoning process. The training of AI models usually requires processing a large amount of data, which is usually stored in a cloud server or a distributed storage system. Through the network card, the AI ​​server can efficiently read data from the storage system and transfer it to the computing resources for processing. In large-scale AI training tasks, high-speed and stable network connections are one of the key factors to ensure training efficiency and performance.   Secondly, the reasoning process of the AI ​​model is also inseparable from the support of the network card. In practical applications, the AI ​​model needs to interact with external devices or users. For example, in image recognition, the AI ​​model needs to receive image input from the camera and transmit the recognition results to the display device or other system. Through the network card, the AI ​​system can receive data from external devices and transmit the results back to achieve real-time communication with the outside world.   In addition, due to the widespread development and popularity of AI applications, there are many scenarios where AI needs to be deployed on edge devices, such as smartphones, smart homes, drones, etc. These edge devices usually have limited computing resources and storage space, so they need to rely on network cards to connect to cloud services and outsource the computing tasks and data transmission of AI models to cloud servers, thereby realizing the intelligence of edge devices.   In addition to the above application relationship, AI and network cards also have some intersections at the technical level. With the widespread application of new AI algorithms such as deep learning, the requirements for computing performance are getting higher and higher. In order to improve computing efficiency and accelerate the training and reasoning process of AI models, some manufacturers have begun to develop specialized AI accelerators, such as GPUs. These accelerators usually need to interact with network cards through specialized interfaces and drivers to achieve efficient data transmission and computing.   In summary, there is a close connection between AI and network cards. Network cards provide efficient and stable network connections for AI systems, supporting data transmission and interaction. At the same time, network cards also play an important role in the development of AI algorithms and hardware accelerators, ensuring the computing efficiency and performance of AI models. It can be said that AI and network cards are interdependent and mutually reinforcing, jointly promoting the development of AI technology.   STOR Technology Limited provides you with high-quality network card adapters such as X550-T2, MCX512A-ACAT, MCX4121A-ACAT, MCX4421A-ACAN, X520-DA2, and provides you with higher quality services and reliable after-sales services.

The storage system has two parts: data storage and data management. The data storage part includes: storage controller hardware, disks, adapters, network transmission channels, RAID management, LUN management, etc. The main function of this part is to provide basic raw data storage services, such as storing data in the corresponding LUN or Read from it. The data management part includes: Tier, Snapshot, Clone and other data processing functional modules. The data management part is mainly responsible for some high-level data processing, just like the social needs hierarchy pyramid. The lowest needs are survival, food and clothing, and clothing. This layer corresponds to the basic storage function of the storage system for data, such as to a piece of data. Data is stored in the disk; further up are higher-level needs, such as not only food and clothing, but also good food, sufficient taste, and rich material, so that you have everything you want. This corresponds to the evolution of storage systems for data storage, such as making multiple hard disks into RAID to improve performance, and dividing LUNs to make space allocation more flexible, and hardware configurations are becoming more and more powerful; however, people's needs are always getting more and more demanding. Crazy and boring, not satisfied, but also pursuing spiritual enjoyment. For example, if you have too much money, go to the streets to spread it, or pretend to be a beggar. This corresponds to more advanced processing of data in the storage system, such as Mirro, Snapshot, etc., and even some flashy functions.   The data management part can be divided into two categories: pre-processing and post-processing of data. Pre-processing refers to the initial processing of the data before it is written to the disk, or the storage space of the data is prepared in advance before being written to the disk for storage. Examples of pre-processing are: Post Deduplication, Thin Provision etc. Post-processing means that after the data is written to the disk, the functional module reads the data for processing, and then writes it back to the disk. Typical examples of post-processing include: BackGround Deduplication, Data Migrating, etc. Some functional modules include both pre-processing and post-processing, such as Snapshot. The generation of Snapshor is a post-processing process, but once the Snapshot is generated, each affected IO will also go through an additional pre-processing process, such as the CoW process, before being written to the hard disk; another example is that MinroMiror can be executed synchronously. It can also be executed asynchronously in the background. The former is pre-processing, while the latter is post-processing.   STOR Technology Limited provides you with high-quality Raid Card, HBA Card, Hard Disk Drive, etc. such as: 05-26105-00, 05-25420-10, 05-50011-02, 05-50134-03. We provide you with higher-quality services and assured after-sales service.

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.   STOR Technology Limited provides you with high-quality Raid Card, HBA Card, Hard Disk Drive, etc. such as: 05-26105-00, 05-25420-10, 05-50011-02, 05-50134-03. We provide you with higher-quality services and assured after-sales service.

Current magnetic disks can be divided into single-disc disks and multi-disc disks. The former has only one disk in the disk body, while the latter has multiple disks. As mentioned before, data can be stored on both sides of each disk, so each disk needs two heads, each reading and writing on one side. However, one thing must be clarified: the disk only allows one head to read and write data at a time. In other words, no matter how many platters and heads there are in the disk, it is impossible to improve the throughput and IO performance of the hard disk, but can only increase the capacity. However, many people are already committed to changing this status quo, hoping to enable the magnetic heads to read and write concurrently within the disk, which is equivalent to forming a RAID between the disks and the disks to improve performance. However, this project has not yet been able to Application products.   Factors that affect hard drive performance include the following: (1) Rotation speed: Rotation speed is the primary factor affecting the throughput performance of the hard disk during continuous IO. When reading and writing data, the magnetic head does not move. It depends entirely on the rotation of the disk to sense the data in the corresponding sector to the magnetic head. Therefore, the faster the disk rotates, the shorter the data transmission time.   In the case of continuous IO, the number of head arm seeks is very small, so to improve the throughput or IOPS value, the rotation speed is the primary influencing factor. At present, mid-to-high-end hard drives generally run at 10,000 rpm or 15,000 rpm. Recently, some manufacturers are trying to achieve 20,000 rpm hard drives, and they already have finished products, but it remains to be seen whether they will be widely used in the end.   (2) Seek speed: Seek speed is the primary factor affecting disk random IO performance. In the case of random IO, the head arm needs to change tracks frequently, and the time spent on data transmission is very small compared to the time consumed by track changing, not at all in the same order of magnitude. So if the head arm can change tracks at a very high speed, it will increase the random IOPS value. The current average seek speed of high-end disks is below 10ms.   (3) Single disk capacity: Single disk capacity is also an indirect factor affecting disk performance. The higher the capacity of a single disk, the greater the amount of data in the same space, that is, the greater the data density. Under the same rotation speed and seek speed conditions, hard drives with high data density will show higher performance. Because under the same overhead, a hard drive with a high single-disk capacity will read more data. At present, manufacturers have developed hard drives with a single-disc capacity of more than 300GB, but they have not been put into use yet.   (4) Interface speed: Interface speed is the least important factor affecting hard disk performance. The current interface speed theoretically meets the highest external transmission bandwidth that the disk can achieve. In a random IO environment, interface speed is even less important, because the bottleneck is almost entirely seek speed. However, high-end hard drives use high-speed interfaces, which is a common practice.   STOR Technology Limited provides you with high-quality Raid Card, HBA Card, Hard Disk Drive, etc. such as: 05-26105-00, 05-25420-10, 05-50011-02, 05-50134-03. We provide you with higher-quality services and assured after-sales service.

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 is a commonly used technology when it comes to data storage and processing. By connecting RAID cards in series, you can increase storage capacity, data redundancy and performance. This article will explain how to properly connect RAID cards in series to achieve the best results.   Step 1: Understand the different types of RAID levels Before you start chaining RAID cards, you need to understand the different RAID levels and the features and benefits they offer. Common RAID levels include RAID 0, RAID 1, RAID 5, RAID 6, etc. You can choose the appropriate RAID level to meet your storage and performance needs.   Step 2: Choose the right RAID card Make sure to choose a RAID card that is compatible with your system and choose the appropriate RAID level and features based on your needs. You can increase storage capacity and performance by plugging in multiple hard drives.   Step 3: Install the RAID card First, make sure your computer is turned off and unplugged from the power source. Then install it into the appropriate slot on your computer according to the guidelines provided by the RAID card manufacturer.   Step 4: Connect the hard drive After installing the RAID card, you need to connect the hard drive. Depending on the specifications of the RAID card, it may provide multiple internal or external interfaces that you can use to connect the hard drives.   Step 5: Configure RAID Level Once the hard drive is connected, you can press the designated key when the computer is turned on to enter the RAID card setup interface. Depending on the RAID level you choose, you can set how the drives are organized into an array, configure redundancy and performance options, and more. Please follow the guidelines provided by the RAID card manufacturer for proper configuration.   Step 6: Initialize and format the array After completing the configuration of the RAID card, you need to initialize and format the RAID array to prepare it for use. This process may be completed in the setting interface of the RAID card, or it may need to be executed in the operating system. Please be sure to follow the RAID card manufacturer's guidelines for proper initialization and formatting.   Step 7: Test and Monitor the RAID Array Finally, before using a RAID array, it is recommended that you test and monitor to make sure everything is working properly. You can use the tools provided with the RAID card to perform integrity checks and performance testing of the array.   By properly cascading RAID cards, you can achieve greater storage capacity, higher data redundancy, and better performance. But remember, before making any changes, make sure to back up important data and carefully read the RAID card manufacturer's documentation and guidelines before starting.   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.

In the vast realm of networking technology, understanding network card models can be a daunting task.   1、The model number contains "T": the interface type is Ethernet interface. For example: I350-T2, X540-T2, X710-T4   2. The model includes "F" and "D": optical fiber interface, used to connect to optical fiber networks, with the characteristics of high-speed transmission and stability. Common abbreviations for optical interfaces: SFP+, SFP28, QSFP, etc. For example: I350-F2, X520-DA2, E810-CQDA2   3. The model number contains "SR": the network card comes with its own module, and the modules are usually divided into single-mode and multi-mode. Single-mode is often used for long-distance transmission, and the wavelengths are: 1310, 1550, and 1490. No light can be seen when the power is on. Multi-mode is often used for short-distance transmission. The wavelength is 850nm. Red light can be seen when the power is on.   4. Finally, the numerical digit at the end of the model holds the key to understanding the quantity of external interface connections. The last number 1 or 2 or 4: the number of external interface connections. For example: X520-DA1, I210-T1, I350-T4, X710-DA4, X520-DA2.   The above information only applies to IN network cards.
