Description

一种兼容SAS、SATA和NVME硬盘的硬盘背板及其设计方法A hard disk backplane compatible with SAS, SATA and NVME hard disks and its design method

技术领域technical field

本发明设计服务器硬盘背板技术领域，具体涉及一种兼容SAS、SATA和NVME硬盘的硬盘背板及其设计方法。The invention relates to the technical field of server hard disk backplane design, in particular to a hard disk backplane compatible with SAS, SATA and NVME hard disks and a design method thereof.

技术背景technical background

随着社会信息化的快速发展，数据量越来越大，企业对存储量和存储的灵活性需求也越发突出，高端存储跃然于纸上。PCIE是最新的总线和接口标准，属于高速串行点对点双通道高带宽传输，所连接的设备分配独享通道带宽，不共享总线带宽。PCIE总线频率提升：每条串行线路的数据传输率从2.5Gbps翻番至5Gbps，带宽也随之翻倍；可更好地支持未来高端显卡，即使功耗达到225W或者300W也只需PCIE单独供电即可。PCIE总线适用于为高端服务器加入多块网卡作为输入输出扩展模块等场合。With the rapid development of social informatization, the amount of data is increasing, and the demand for storage capacity and storage flexibility of enterprises is becoming more and more prominent. High-end storage is on paper. PCIE is the latest bus and interface standard. It belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices allocate exclusive channel bandwidth and do not share bus bandwidth. Increased PCIE bus frequency: The data transmission rate of each serial line doubles from 2.5Gbps to 5Gbps, and the bandwidth also doubles accordingly; it can better support future high-end graphics cards, even if the power consumption reaches 225W or 300W, only PCIE alone is needed for power supply That's it. The PCIE bus is suitable for adding multiple network cards to high-end servers as input and output expansion modules.

针对不同的服务器主板，往往需要设计单独的SAS，SATA或者PCIE存储背板来满足系统设计的需求，灵活性较差。为了提高存储的灵活性以适应不同系统的配置需求，可以设计一个能够复用SAS，SATA和NVME硬盘的硬盘背板，并且可以根据需求增加或者减少端口的数量，从而满足多种服务器产品的存储设计需求。For different server motherboards, it is often necessary to design a separate SAS, SATA or PCIE storage backplane to meet the requirements of system design, which is less flexible.
