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.
