Problems solved by technology

[0002] As the price of flash memory is getting lower and lower, and the storage capacity is getting bigger and bigger, its cost performance gradually exceeds that of traditional hard disks, tapes and other memories to form storage servers, and storage servers are generally deployed in a centralized manner, due to heat dissipation, power consumption and other reasons The deployment locations are quite special. For example, some of Google’s storage servers are deployed on the shallow seabed, while Apple China, Tencent, and Alibaba are located in mountain caves in Guizhou, China. There are fewer on-site maintenance personnel and the space of the storage array is relatively narrow. Data migration and then dismantling the device for replacement is inefficient and error-prone, and the maintenance cost is also high
Therefore, there is an urgent need for a storage system that can perform chip repairs online to solve the problems of inconvenient on-site maintenance and high cost of direct discarding and replacement.

Embodiment Construction

[0013] The present invention provides a storage server online repair system based on flash memory, such as figure 1 As shown, the storage server online repair system includes a processing unit, a data filtering unit, a decision repair unit, a storage unit, and a physical address memory;

[0014] The processing unit includes a CPU array and a cache array, the CPU array is used for processing data calculation and data flow control; the cache array is used for storing temporary processing data;

[0015] The physical address memory can be a separate memory or a flash memory unit specially used to store the physical address of abnormal data opened from the storage unit;

[0016] The storage unit includes a plurality of flash memory units,

[0017] The data filtering unit is only used to filter whether the data read from the storage unit has data abnormality, and if there is any abnormality, the physical address of the abnormal data in the storage unit is traced; and the physical a...

Abstract

The invention discloses a storage server online repair system based on a flash memory, which can realize online repair in remote areas, especially in harsh and severe environments by introducing the online repair system into the storage server based on the flash memory, and solves the problems of narrow space of a storage array, inconvenience in manual maintenance, low repair efficiency and the like. The efficiency is low; errors are easy to occur; and the maintenance cost is high.

Description

technical field [0001] The invention relates to a storage server, in particular to a system capable of repairing damaged storage online. Background technique [0002] As the price of flash memory is getting lower and lower, and the storage capacity is getting bigger and bigger, its cost performance gradually exceeds that of traditional hard disks, tapes and other memories to form storage servers, and storage servers are generally deployed in a centralized manner, due to heat dissipation, power consumption and other reasons The deployment locations are quite special. For example, some of Google’s storage servers are deployed on the shallow seabed, while Apple China, Tencent, and Alibaba are located in mountain caves in Guizhou, China. There are fewer on-site maintenance personnel and the space of the storage array is relatively narrow. Data migration and then dismantling the device for replacement is inefficient and prone to errors, and the maintenance cost is also high. The...
