Abstract

The invention provides a storage system and a data transmission method. The storage system comprises a host and at least two JBODs which are sequentially arranged; according to the forward arranging sequence of the JBODs, a first output port of any one current JBOD is connected with a first input port of the next JBOD, a first input port of the first JBOD is connected with a main control port of the host, and then a main control link is formed; according to the reverse arranging sequence of the JBODs, a second output port of any one current JBOD is connected with a second input port of the next JBOD, a second input port of the first JBOD is connected with a standby control port of the host, and then a standby control link is formed; the host transmits JBOD access information through the main control link and the standby control link jointly when at least one of the JBODs works abnormally. According to the scheme, the data transmission reliability can be improved.

Description

technical field

[0001] The invention relates to the field of computer technology, in particular to a storage system and a data transmission method. Background technique

[0002] JBOD (Just a Bunch Of Disks, disk cluster) is a storage device with multiple disk drives installed on a backplane, and is an important storage device in the storage field. On some large servers, multiple JBODs are connected to form a storage system to obtain sufficient storage space.

[0003] At present, when multiple JBODs are connected to form a storage system, each JBOD is connected through a main control connection line and a standby control connection line, wherein the arrangement order of each JBOD on the main control connection line and the standby control connection line is the same, and The direction of the data flow on the main control connection line and the standby control connection line is the same. When the main control connection line is abnormal, the data flow is transmitted by the...
