Hardware architecture for flexibly allocating hard disk port numbers and implementation method thereof

Abstract

The invention discloses a hardware architecture for flexibly allocating hard disk port numbers and an implementation method thereof, and the hardware architecture for flexibly allocating the hard diskport numbers comprises a server mainboard, a Raid card, an extended Expander card and a hard disk backboard, the hard disk backboard is connected with a plurality of hard disks; the server mainboardis connected with the hard disk backboard through a Raid card and an Expander card, and is used for allocating hard disk port numbers to the plurality of hard disks according to the logic phy stored in the Expander card; the Expander card comprises an Expander chip and a port physical layer phy write-in module, wherein the Expander chip comprises an erasable memory, the erasable memory stores a corresponding relationship between logic phy and physical phy, the physical phy corresponds to a plurality of hard disks, and the phy writing module is electrically connected with the erasable memory and is used for erasing the corresponding relationship between the logic phy and the physical phy in the erasable memory. According to the architecture, the problem that the port number allocated to thehard disk by the operating system is uncontrollable in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a hardware architecture for flexible allocation of hard disk port numbers and an implementation method thereof. Background technique [0002] With the development of data link, big data and cloud computing technologies, storage servers, especially mass storage servers, have become the computing and storage devices used by major Internet companies. In addition, the growing demand of users for data storage, processing and services has also caused the underlying hardware architecture of storage servers to become increasingly complex; in order to adapt to the complexity of the underlying hardware architecture of storage servers, the software architecture of the upper application layer is also becoming larger and more complex. [0003] In order to solve the above-mentioned contradictions, some Internet users may not wish to adjust the upper-layer software architecture in today's inc...
