Abstract

The invention discloses a storage system and a caching method thereof. The system comprises an iSCSI client side, an iSCSI gateway and a storage server, the iSCSI gateway comprises a high-speed disk,the iSCSI gateway receives a read command or a write command sent by the iSCSI client side, data are written into the high-speed disk according to the write command; when the high-speed disk reaches athreshold value or does not receive a data writing or reading request within preset time, writing the data in the high-speed disk into a storage server; and reading the data from the high-speed diskaccording to the reading command, and reading the data from the storage server when the read data does not exist. By implementing the method and the system, the high-speed disk is arranged in the gateway, when data is written, the data is firstly written into the high-speed disk, and then the data which is not commonly used is brushed into the storage server. In the data reading process, the datais read from the high-speed disk firstly, and if the data does not exist in the high-speed disk, a request is sent to the storage server, so that higher storage performance can be achieved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a storage system and a caching method thereof. Background technique [0002] iSCSI is an industry standard that uses the TCP / IP protocol to transmit SCSI block commands over an existing IP network. breakthrough technology. Based on the widely used TCP / IP protocol, iSCSI encapsulates SCSI commands / data blocks into iSCSI packets, then encapsulates them into TCP packets, and then encapsulates them into IP packets. iSCSI protects the reliable delivery of data blocks through the TCP connection-oriented protocol. Because iSCSI is based on the IP protocol stack, it can be transmitted on standard Ethernet devices through routers or switches. [0003] However, although the existing iSCSI gateways use distributed cluster storage service devices, most of the current storage service devices use mechanical hard disk storage. When the mechanical hard disk is used to execute the read an...
