Method and system for expanding storage capacity in server system

Abstract

The present application discloses a method and system for expanding storage capacity in a server system. The method includes: storing the data to be stored in the first NVMe hard disk, obtaining the current temporarily stored data capacity of the first NVMe hard disk; judging whether the data capacity is ≥ The set storage capacity threshold; if yes, turn on the PCIe Switch that matches the first NVMe hard disk and the power of the second NVMe hard disk; transfer the temporarily stored data in the first NVMe hard disk to the second NVMe hard disk; return to the first step. The system includes: a plurality of first NVMe hard disks, a plurality of PCIe Switches, a first NVMe hard disk data capacity acquisition module, a judging module, a power supply opening module, a data transmission module and a plurality of second NVMe hard disks. A PCIe Switch is connected to a first NVMe hard disk through a PCIe link. The first NVMe hard disk is also connected to the CPU through a PCIe link. Through the application, while expanding the storage capacity of the server, the power consumption of the server system can be greatly reduced, which is beneficial to energy saving.

Description

technical field [0001] The present application relates to the technical field of server storage, and in particular, to a method and system for expanding storage capacity in a server system. Background technique [0002] In the field of server storage technology, the current main storage device is an NVMe (Non-Volatile Memoryexpress, non-volatile memory host controller interface specification) hard disk. The NVMe hard disk is usually connected to the CPU in the server system through a PCIe (peripheral component interconnect express, a high-speed serial computer expansion bus standard) link. However, the CPU PCIe ports in the server system are limited, and how to increase the NVMe hard disk inside the system as much as possible in the limited CPU PCIe ports, thereby expanding the storage capacity of the entire server, is an important issue. [0003] The schematic diagram of the structure of the current device for expanding the storage capacity of the server can be found in f...
