A kind of hard disk storage system of Ethernet architecture and hard disk data operation method

Abstract

The invention relates to a hard disk storage system of an Ethernet framework and a hard disk data operation method. The hard disk storage system at least comprises a hard disk and at least two controllers including the first controller and the second controller, each hard disk is provided with at least two Ethernet interfaces, and the at least two controllers are connected with the at least two Ethernet interfaces of the at least one hard disk; the first controller is used for receiving an application or a data operation request of the application forwarded through the second controller, data required to be operated are packaged / unpackaged with a main key Key-Value protocol, the packaged data are written into the at least one hard disk through the Ethernet, or the unpackaged data are returned to the application or returned to the application through the second controller. Data operation is carried out through the hard disk storage system based on the Ethernet framework, deployment is flexible due to the fact that data operation can be based on the existing Ethernet, the expansibility is high, an Ethernet protocol stack is simpler than the SAS protocol stack, a special communication link and a host bus adapter are not needed, and the cost superiority is large.

Description

technical field [0001] The invention relates to the field of storage, in particular to a hard disk storage system with an Ethernet architecture and a hard disk data operation method. Background technique [0002] At present, the mainstream hard disk in the industry is Serial Attached SCSI (Small Computer System Interface, SCSI), SAS), Serial ATA (Serial ATA (Advanced Technology Attachment, hard disk interface technology, ATA), SATA) interface SAS disks have dual ports and can be accessed by two controllers, while SATA disks have only one port and can only be accessed by one controller. SAS disks have higher reliability, but the price is also higher; SATA disks are slightly less reliable, but the price is also lower than that of SAS disks. [0003] In order to connect the central processing unit (CPU) system to the SAS or SATA hard disk, it must pass through the SAS controller (SAS Controller) chip, which generally has only 8 to 16 ports at most, and cannot connect many hard...

AI Technical Summary

Problems solved by technology

[0007] SAS-related devices such as SAS Controller, SAS Expander, SAS hard disk or SATA hard disk are expensive, and the SAS protocol is complex and difficult to implement. These factors make the current hard disk storage system complex in software and hardware, and expensive
