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.

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.

Currently, there are four main interfaces supported :IDE, SCSI, SATA and SAS.

 

The IDE interface is the standard interface for ordinary PCS.

 

SCSI: small computer system interface, and SCSI is not specifically designed for the hard disk interface, a wide range of applications, low CPU usage, mainly used for servers.

 

SATA: Serial port is better and faster, the main PC, the use of SATA(Serial ATA) port hard disk is also called serial hard disk, is the mainstream of the current PC hard disk, serial ATA bus uses embedded clock signal, has a stronger error correction ability, improve the reliability of data transmission.The serial interface also has the advantages of simple structure and hot swap support.

 

SAS: SAS is a new generation of SCSI technology, which uses serial technology to obtain higher transmission speed, and SAS interface technology can be backward compatible with SATA. Due to the compatibility of SAS systems, IT personnel can use hard disks with different interfaces to meet the capacity or performance needs of various applications.

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.
