At present, we know that NAS network storage server, mainly composed of storage devices and embedded software. The storage device is the medium of data storage, so the NAS system is the operation management system running on the storage device.
The software system of NAS equipment must have several functions: software management coordination, network function, data reading and device driver.
1、Support for a core operating system.
2、A device driver module for a corresponding device (such as a network device, a storage device).
3、Support for some basic network protocols (more network and storage capabilities to be considered as network storage servers).
4、Some file sharing protocols for network data access to private network storage servers.
5、Network storage server provides some network applications (such as remote network management, optical disk automatic mirror and network burning, etc.).
6、I / O optimization module (mainly for read and write performance optimization).
