TECHNICAL FIELD

The present disclosure relates to network technologies, and in particular, to a network storage device.

BACKGROUND

A network storage device is an application system that stores data of a user on the Internet. Whenever and wherever possible, the user can upload a file to the network storage device, can download a file from the network storage device, can manage a file stored in the network storage device, or can share a file stored in the network storage device with another person.

Currently, most network storage devices are implemented using a network hard disk that has a network function. The network storage device is based on a hard disk that supports the serial attached SCSI (SAS) (where SCSI referred to small computer system interface)/a serial at attachment (SATA) hard disk, a converting circuit is added to an exterior of the hard disk, and a network interface is provided using the converting circuit.FIG. 1is a schematic structural diagram of an existing network storage device, andFIG. 2is a cross-sectional view of a storage shelf inFIG. 1in an A-A direction. As shown inFIG. 1, a cabinet14includes a network switch11and multiple storage shelves12, the storage shelves12are connected to the network switch11using a cable13to implement a function of storing data of a device and a user, and the multiple storage shelves12are installed inside the cabinet14in stack mode. As shown inFIG. 2, a switch board21, a heat dissipation unit22, and a hard disk area23are integrated in each storage shelf12, and multiple hard disk units24can be disposed in the hard disk area23, to form a storage array.

However, as network users gradually increase, a requirement for a network storage capacity is increasingly high. When a solution in the prior art is used for expansion, storage shelves need to be expanded one by one, storage density is limited, and expansion flexibility is not high.

DESCRIPTION OF EMBODIMENTS

FIG. 3is a schematic structural diagram of a network storage device according to Embodiment 1 of the present disclosure. As shown inFIG. 3, the network storage device includes a cabinet31, a network switch32, and a hard disk area34. The network switch32and the hard disk area34are installed inside the cabinet31, the hard disk area34includes at least one hard disk35, each hard disk35is fastened to the cabinet31using a mounting bracket, each hard disk35in the hard disk area34and the network switch32have a same type of interface, and the hard disk35and the network switch32are connected using a cable or a PCB. Each hard disk35in the hard disk area34and the network switch32have a same type of interface means that each hard disk35and the network switch32have a same-protocol-based interface. The network switch32and the hard disk area34may be arranged in another form, which is not limited herein.

According to the network storage device in this embodiment, a network switch and a hard disk area are integrated in a cabinet, multiple hard disks may be disposed in the hard disk area, a quantity of hard disks in the hard disk area may be flexibly set according to a requirement, and all devices are densely disposed, thereby greatly alleviating a problem that storage density is limited. Each hard disk is fastened to the cabinet using a mounting bracket such that when a requirement for a storage capacity of the network storage device increases, expansion may be performed by increasing a quantity of mounting brackets that fasten hard disks, and expansion flexibility is high.

Preferably, based on Embodiment 1 described above, the network storage device further includes a heat dissipation apparatus33, and the heat dissipation apparatus33is disposed inside the cabinet. The network switch32expands connection of a network, and provides more connection ports for a subnet. The heat dissipation apparatus33may be a fan, and provides a heat dissipation function for each hard disk35to prevent a function of the hard disk35from being affected because of the overheated hard disk. The hard disk35in the hard disk area34is an Internet Protocol (IP) hard disk, which provides an interface such that communication with an upper-layer network can be performed directly using the IP. However, for a conventional hard disk that supports an SAS/SATA interface, a switch board needs to be added to implement communication between the hard disk and an external network. Because the switch board is added, a quantity of link accesses increases, power consumption increases, reliability becomes low, and costs are high. Each hard disk35in the hard disk area34and the network switch32may be further connected using a cable or a PCB.
