Abstract

The invention discloses a device capable of improving the performance of disk arrays and belongs to the technical field of improvement in the performance of the disk arrays. The structure of the device comprises a host interface, an RAID controller I, an RAID controller II, a disk controller and the disk arrays, wherein the host interface is connected with the RAID controller I by a high-speed PCIE bus directly or by optical fibers, Ethernet, SAS from the Internet; the RAID controller I and the RAID controller II as well as the RAID controller II and the disk controller are connected by a high-speed PCIE bus; and the disk controller is connected with the disk arrays through a data wire. Compared with a method for improving the performance of the disk arrays by using isolated controllers in the prior art, the device capable of improving the performance of the disk arrays performs double controller parallel processing by using the respective independent DMA accesses of the two controllers, thereby greatly improving the whole performance of the disk arrays.

Description

technical field [0001] The invention relates to the technical field of improving the performance of a disk array, in particular to a device capable of improving the performance of a disk array. Background technique [0002] In today's network age, storage technology is undergoing revolutionary changes. The reason leading to this revolutionary change is firstly manifested in the rapid expansion of storage capacity. In the era of digitalization and the Internet, the widespread deployment of large-scale application systems poses a huge challenge to the performance and functions of network storage systems, mainly manifested in high performance, scalability, shareability, adaptability, manageability, and high reliability. [0003] With the increasing application of data storage in the IT field, the demand for large-capacity and high-performance disk array equipment is also growing rapidly. However, the improvement of the performance of disk array equipment lags far behind the ...
