Embodiment 1
[0066] A storage device is also provided in this embodiment. As used below, the term "module" can be a combination of software and / or hardware that can realize predetermined functions.
[0067] figure 2 is a structural block diagram of a storage device according to an embodiment of the present invention, such as figure 2 As shown, the storage device includes: a disk array 20, a first controller 22, a second controller 24, a third controller 26 and a chassis resource module 28, wherein,
[0068] The first controller 22 and the second controller 24 are mutually active and standby controllers and are connected to the disk array 20 for managing the disk array 20;
[0069] The third controller 26 is connected to the chassis resource module 28 for managing the chassis resource module 28 .
[0070] like figure 2 As shown, there may be various connection modes between the first controller 22 and the second controller 24 and the disk array 20, for example, in the case of a dual-c...
Embodiment 2
[0096] In this embodiment, a resource management method is provided, which is applied to a storage device including a disk array, a first controller, a second controller, a third controller, and a chassis resource module. Figure 7 is a flowchart of a resource management method according to an embodiment of the present invention, such as Figure 7 As shown, the process includes the following steps:
[0097] Step S702, the first controller and the second controller manage the disk array in the manner of mutual active and standby controllers; and
[0098] Step S704, the third controller manages the chassis resource module.
[0099] It should be noted that the execution order of step S702 and step S704 is independent of each other, and there is no specific order, and the execution order can be interchanged, that is, step S704 can be executed first, and then S702 can be executed.
[0100] Through the above steps, since in the storage device, the disk array is managed by the firs...
Embodiment 3
[0121] Figure 8 It is a detailed structural diagram of a storage device containing a dual-controller disk array according to an embodiment of the present invention. Figure 9 is a detailed structural diagram of a storage device containing a single-controller disk array according to an embodiment of the present invention. like Figure 8 as shown in Figure 8 As shown, the dual-control management method inside the storage device is as follows:
[0122] The general controller M (corresponding to the third controller in the aforementioned embodiments) manages resources such as chassis fans, temperature sensors, and power supplies in a unified manner (the managed resources correspond to the chassis resource modules in the aforementioned embodiments). It does not rely on the A controller (corresponding to the first controller in the previous embodiment) or the B controller (corresponding to the second controller in the previous embodiment), independently to control the chassis f...
