Cold storage server hard disk extending design method

Abstract

The invention provides a cold storage server hard disk extending design method, and belongs to the field of universal servers. The cold storage server hard disk extending design method comprises the design steps of 1, designing a cold storage server PCIE distribution architecture, and achieving support of BMC, PCIE x8 Slot, OCP connector, NVME SSDx2 and multiple SATAs; 2, designing a cold storage server hard disk extending architecture, introducing a PCIE expanding SATA chip, and achieving expanding design of 19 SATA hard disks and 2 NVME hard disks; 3, designing a cold storage server hard disk management architecture, collecting SATA status information through a CPLD to achieve hard disk status indication, and communicating the CPLD with a BMC to perform hard disk management. According to the cold storage server hard disk extending design method, the cold storage server system storage capacity is increased, the management function is introduced, and system maintenance is facilitated.

Description

technical field [0001] The invention relates to the field of general servers, in particular to a cold storage server hard disk expansion design method. Background technique [0002] With the development of cloud computing, data centers have higher and higher requirements for storage capacity, and higher-density, cost-effective, and more energy-efficient servers are constantly being introduced. The continuous increase in data storage has led to the differentiation of data storage and access strategies. According to the frequency of data access, data can be divided into hot data, warm data and cold data. With the development of big data mining technology, more and more cold data is involved in calculation and analysis, and the ever-expanding demand for cold storage places higher and higher requirements on the capacity, power consumption and cost of cold storage systems. [0003] In the prior art, cold storage servers usually use some low-power, highly integrated CPUs, such as...
