Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] The method for dynamically modifying JBOD IDs in the present invention to realize JBOD interconnection is specifically the method that Expander dynamically modifies JBOD IDs by obtaining GPIO status, and uses JBOD IDs to mark cabinets, thereby realizing redundant interconnection of multiple JBOD cabinets and correct positioning of hard disks.

[0019] The method that the present invention dynamically modifies JBOD ID and realizes JBOD interconnection is as follows:

[0020] The Expender dynamically modifies the JBOD ID by obtaining the GPIO status. The Expander can read the GPIO status infor...

Abstract

The invention discloses a method for realizing just bundle of disks (JBOD) interconnection through dynamically modifying JBOD identities (ID). The method comprises the following steps: Expender dynamically modifies the JBOD IDs through obtaining general purpose input / output (GPIO); the Expender sets the corresponding ID numbers for JBOD cabinets according different read GPIO states; and the cabinets are marked through the JBOD IDs so as to carry out the redundant interconnection of a plurality of the JBOD cabinets. Through the method of dynamically modifies the JBOD ID through obtaining the GPIO, the cabinets are marked through the JBOD IDs, accordingly, the redundant interconnection of the plurality of the JBOD cabinets is realized, and the JBOD has better JBOD robustness; moreover, the mode is simple to realize through GPIO state judgement; and the JBOD IDs are modified without JBOD restarting.

Description

technical field [0001] The invention belongs to the technical field of computer JBODs, and relates to a method for dynamically modifying JBOD IDs to realize JBOD interconnection. Background technique [0002] JBOD stands for Just a Bunch of Disk. The disk controller regards each physical disk as an independent disk, so each disk is an independent logical disk. In the process of interconnecting multiple JBODs, there will be multiple connection methods. The traditional connection method is: main cabinet-JBOD1-JBOD2-JBOD3. The order of the Expanders is sorted, and the controls on both sides can be automatically kept consistent, but the Expanders are different, that is, the order of the Expanders at this time represents the sequence number of the JBOD cabinet. [0003] However, in this connection mode, when one of the JBOD hosts is abnormal, the subsequent JBODs cannot work normally. [0004] Therefore, it is necessary to conduct research and development to provide a solution ...
