Embodiment Construction

[0012] A design method of an iSCSI storage server using an independent high-speed cache according to the present invention will be described in detail below with reference to the accompanying drawings.

[0013] Specific steps are as follows:

[0014] (1) When the system starts up, reserve enough memory before memory initialization to be used as a disk cache. This memory area must be in the NVDIMM memory area;

[0015] (2) When the storage server is working normally, all iSCSI read and write commands complete the corresponding read and write operations through the disk cache. When the storage server receives an iSCSI read command, it first searches in the disk cache, and if it finds the corresponding data, it directly returns it to the client; if it does not find the corresponding data, it reads the data from the disk into the disk cache, and then Return to the client; when the storage server receives the iSCSI write command, it directly copies the data to the corresponding ar...

Abstract

The invention provides a method for designing an iSCSI storage server with an independent cache. The independent disk cache is developed in a fixed internal storage physical area, and corresponding reading and writing operation of iSCSI reading and writing commands is completed through the disk cache; when the power failure situation occurs, data in the disk cache can be stored in Flash of an NVD IMM (non-volatilememory), and the data can be written back into a disk after the storage server is restarted.

Description

technical field [0001] The invention relates to the technical field of computer storage server design, in particular to an iSCSI storage server design method using an independent high-speed cache. Background technique [0002] 1) iSCSI (Internet SCSI) is a standard protocol formulated by IETF (Internet Engineering Task Force) and officially released in February 2003. It can be understood as SCSI over TCP / IP, that is, SCSI on the network. It actually compresses SCSI commands into TCP / IP packets so that data blocks can be transmitted over the network. iSCSI integrates SCSI, Ethernet and TCP / IP technologies, and has many advantages such as low cost, openness, large capacity, high transmission speed, compatibility, security, etc. Its superior performance has attracted the attention of the market since its release. And favored, iSCSI has become one of the core technologies in the field of network storage. [0003] 2) The disk cache is to reduce the number of times the CPU reads...
