Network attached storage system and method for starting same

Abstract

The invention provides a network attached storage (NAS) system, which comprises a first non-volatile memory, a volatile memory and a second non-volatile memory; the second non-volatile memory comprises a second operating system providing the network attached storage extending function; and the first non-volatile memory comprises a bootstrap program, a first operating system used for providing the network attached storage basic function, and a starting sequence management module used for controlling the starting sequence of the NAS system according to the software and hardware information of the system, and loading the bootstrap program, the first operating system or the second operating system to the volatile memory for running. The invention also provides a method for starting the NAS system. NAS software systems with different functions are stored to different storage media, so the same set of Mini-OS and different versions of Full-OS are adopted to meet the requirements of different users, and simultaneously the factory cost of the NAS system is reduced.

Description

technical field [0001] The invention relates to a network attached storage system and its starting method. Background technique [0002] Network Attached Storage (NAS) is a technology that integrates distributed and independent data into a large, centrally managed data center for easy access to different hosts and application servers. Literally speaking, it is a device that is connected to the network and has the function of data storage, so it is also called "network storage". In the field of network storage, based on the pressure of cost reduction, reducing the expensive Flash Memory capacity and shipping without hard disk (Zero-disk) are adopted by more and more manufacturers. Therefore, traditional NAS solutions generally have the following two types: [0003] 1. Adopt PC architecture hardware platform such as X86. The Flash Memory of this NAS system is generally small, and only small programs such as bootloader can be placed on the Flash Memory, while the OS program c...

Problems solved by technology

[0005] In Solution 1, when shipping without a hard disk or the user replaces the system hard disk or formats the hard disk, or the OS program on the hard disk crashes, because the NAS system generally does not have interfaces such as display screen, mouse, keyboard, CD-ROM, and floppy drive, the OS program will run on the NAS. Inconvenient installation on the system hard drive

In the second solution, when considering the high cost of Flash Memory, manufacturers will try their best to cut down the software system in order to reduce the capacity of Flash Memory, so that the software functions of such NAS products are generally not powerful enough
