Using NAS network storage server

Use Yun Qi box as a network file storage server.

NAS is a storage device connected to a network switch through an RJ45 network interface. It is mainly used to share storage space among multiple computer hosts in the LAN environment and provide file sharing services for computers in the LAN, so it is also called a file server.

NAS storage devices include at least two basic components: hardware and an operating system optimized for file sharing applications. Hardware includes CPU, memory, motherboard and multiple hard disks with RAID function. The CPU and memory of small NAS are generally embedded in the motherboard, and the number of hard disks is generally 2-5, which supports RAID redundancy. The software is generally optimized and customized by the open source operating system (FreeBSD, Linux) for file sharing applications, and FreeNAS is a very popular file sharing FreeBSD operating system. It is also cut from windows XP, and Microsoft also has a dedicated NAS operating system WSS.
