JBOD cold storage device and mechanical positioning hard disk data interaction system thereof

Abstract

The invention discloses a mechanical positioning hard disk data interaction system, which comprises a storage box for storing a plurality of hard disks, an electrical box connected with the storage box, and a hard disk connector movably arranged in the electrical box, the drive controller is arranged in the electrical box, is in signal connection with a server and is used for driving the hard disk connector to be connected with the data interface of the corresponding hard disk according to a control instruction of the server, and the data interface of each hard disk stored in the storage box is exposed. Thus, the arrangement of the SAS Expander is abandoned, the purchase cost and the power supply cost for the SAS Expander are directly saved, meanwhile, all the hard disks do not need to be in the standby state, only one hard disk is in the power-on state generally in the operation process, the other hard disks can be in the non-power-on state, the power supply requirement is reduced, energy consumption can be reduced, resource waste is avoided, and the power supply efficiency is improved. The total ownership cost is reduced. The invention further discloses JBOD cold storage equipment, and the beneficial effects of the JBOD cold storage equipment are as described above.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a mechanical positioning hard disk data interaction system. The invention also relates to a JBOD cold storage device. Background technique [0002] With the rapid development of technology and life, data is growing exponentially. [0003] According to the different access frequency, data can be divided into three types: hot data, warm data and cold data. Among them, cold data refers to data that is infrequently active, not frequently accessed (or even never accessed) but still needs to be retained for a long time, while cold storage devices are devices dedicated to storing cold data. [0004] When disk equipment is expensive, CDs are usually used to back up stored data, burn the data into CDs, store the CD numbers in the CD cabinet, and take them out for use only when needed. As the storage capacity of mechanical hard disks increases and the cost decreases, mechanical hard dis...

AI Technical Summary

Problems solved by technology

[0006] In the existing technology, a large number of hard disks need to be installed in the JBOD system, and each hard disk needs to be interconnected through SASExpander. However, in the cold storage environment, only a small number of hard disks need to read and write data, while the rest In order to maintain the interconnection state, the hard disk must be kept in the standby state at all times, which leads to waste of resources and high energy consumption

At the same time, due to the high cost of SAS Expander interconnection devices, and the large demand for power supply that requires a large number of hard disks to maintain standby status, the TCO (Total Cost of Ownership, total cost of ownership) of the JBOD system is relatively high.
