Embodiment Construction

[0023] The scheme of the present invention utilizes the Target mode (hereinafter referred to as T) driver program and the Initiator mode (hereinafter referred to as I) driver program of the existing mature FC port of the storage manufacturer, regards the I / T driver as the management module of resources, and the FC port then For hardware resources, add a resource scheduling module between I / T drivers, and allocate FC ports to I / T drivers according to requirements, so as to realize online multiplexing of FC ports.

[0024] In order to make the principles and technical effects of the present invention clearer, the solution of the present invention will be described in detail below through specific examples.

[0025] figure 1 A schematic structural diagram of a storage system provided by an embodiment of the present invention is shown, which includes a first FC port 101, a second FC port 102, an active mode driver module 103, a passive mode driver module 104, an FC resource schedu...

Abstract

The invention provides a memory system. The memory system comprises an active mode driving module, an passive mode driving module, an fiber channel resource dispatching module, a user interface (UI) configuration module and at least one fiber channel port, wherein the fiber channel resource dispatching module is used for dispatching the fiber channel port as hardware resource to the active mode driving module or the passive mode driving module according to dispatching instructions from the UI configuration module; the active mode driving module is used for using an active mode driving program to drive the fiber channel port dispatched to the module into an active mode; the passive mode driving module is used for using a passive mode driving program to drive the fiber channel port dispatched to the module into a passive mode; the UI configuration module is used for transmitting dispatching instructions to the fiber channel resource dispatching module, wherein the dispatching instructions comprise marks of dispatched fiber channel ports and corresponding working modes.

Description

technical field [0001] The invention relates to the field of computer storage devices, in particular to a storage system and a method for switching FC port working modes online. Background technique [0002] In the Fiber Channel Storage Area Network (FC-SAN, Fiber Channel-Storage Area Network) storage system, Fiber Channel (FC) as the host port is very frequently used, and most of them have more than two FC ports as the host interface, and some systems It can even reach 16 FC host ports. [0003] According to the working mode, FC ports can be divided into passive mode (Target mode) ports and active mode (Initiator mode) ports. Most of these host ports are only used as single passive mode ports. But in some applications, not all ports are used as passive mode; or, in some advanced applications, FC ports are required to be used as active mode ports. If the same FC port can support Target mode and Initiator mode in different applications, the application range of FC port can...
