Embodiment 1

[0026] see figure 1 , is a schematic structural diagram of a storage device provided in Embodiment 1 of the present invention. The storage device includes: a storage controller 110 , a switch module 120 and a storage module 130 .

[0027] The storage controller 110 is used to be connected to the processor unit, and is also used to be connected to the uplink PCIe interface of the switch module 120 through a high-speed peripheral component interconnect (PCIe) interface; the switch module 120 includes several downlink PCIe interfaces for to be connected to at least one storage module 130 .

[0028] Compared with the manner in which the storage device is directly connected to the PCIe interface of the processor unit, due to the limitation of the number of PCIe interfaces, the number of storage devices connected to the processor unit is limited and cannot be expanded. Exemplarily, assuming that the number of PCIe interfaces is one, the processor unit can only access one storage d...

Embodiment 2

[0046] see Figure 4 , is a schematic structural diagram of a system for accessing a storage device provided by Embodiment 2 of the present invention. The system includes: a processor unit 410 and a storage device 420 provided by any embodiment of the present invention, and the processor unit 410 is connected to a storage controller in the storage device 420 .

[0047] For the structure of the storage device 420 and the connection relationship and functions of each component, reference may be made to the above-mentioned embodiments, which will not be repeated in this embodiment.

[0048] The system for accessing a storage device provided by the embodiment of the present invention has the beneficial effects corresponding to the storage device provided by the above embodiment, and details are not repeated here.

[0049] In the above solution, the storage controller may be deployed on the side of the device to which the processor unit 410 belongs.

[0050] The advantage of this...

Abstract

Embodiments of the invention provide storage equipment and a system for accessing the storage equipment. The storage equipment comprises a storage controller, a switching module and at least one storage module, wherein the storage controller is connected with a processor unit and connected with an upstream PCIe interface of the switching module through a PCIe interface; and the switching module comprises a plurality of downstream PCIe interfaces and is connected with the at least one storage module. Through adding the switching module, the quantity of the storage modules which can be accessed by the processor unit is extended; through distributing at least one storage module around the switching module, the integration levels of the switching module and the supported storage modules are improved; and by adoption of an independent hot plug manner, the maintainability is improved and the quantity of the storage modules can be flexible adjusted.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of storage, and in particular, to a storage device and a system for accessing the storage device. Background technique [0002] In current network application scenarios, high-speed peripheral component interconnect express (PCIe) is a high-speed serial computer expansion bus standard proposed by Intel in 2001. PCIe belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices allocate exclusive channel bandwidth and do not share bus bandwidth. It mainly supports functions such as active power management, error reporting, and end-to-end reliable transmission. [0003] The Non-Volatile Memory Express (NVMe) standard is a storage controller interface standard developed for enterprises and general client systems that use PCIe solid-state storage devices. The memory under the NVMe architecture can improve performance and can Reduced latency ...
