Abstract

The invention provides an optical fiber communication method and relates to the technical field of NVME interface standards. The method mainly comprises the three steps of firstly installing device drivers; secondly performing device management based on an NVMe SSD user space management tool Nvme-cli hosted and developed by a maintainer Keitch Busch; and finally performing pressure testing on a device to detect device performance and viewing smart information through the Nvme-cli to view a device state. The invention provides a series of management methods from device driver installation to device detection, thereby filling the technical blanks.

Description

technical field [0001] The invention relates to the technical field of NVME interface standards, in particular to a management method for an Intel SSD hard disk based on an NVME interface. Background technique [0002] Introduction to NVME interface: [0003] In the traditional storage architecture, due to the limitation of the access speed of the hard disk, the common SATA and SAS interfaces in the past can fully meet the bandwidth requirements of the hard disk. However, in the face of hundreds of times the speed of flash memory, the bandwidth of the interface has become the biggest bottleneck of I / O. . It can be said that the excellent performance of flash memory shifts the storage bottleneck from the medium to the interface in one fell swoop. The NVMe standard formulated for the PCIe interface came into being. The standard is led by 13 initiators including IDT, Dell, Intel, EMC, NetApp, Oracle, and Cisco, and is jointly developed by more than 80 industry-leading compan...
