Let's take NAS storage as an example. All storage can actually be regarded as a simplified server, or called a "slimming server".
Its core also includes motherboard, CPU, memory and hard disk controller, RIAD controller and so on. However, there are generally no external devices such as keyboards and monitors, and they are directly connected to network switches through network cables. Users' computers can log in to NAS directly, manage NAS, and access data using a browser without loading any drivers. Therefore, the installation, expansion and maintenance of NAS are very convenient, and ordinary users can complete it without professionals. Using the system administrator, users can set up encrypted storage space in the NAS vendor, and users can regard NAS as another local hard disk. Most NAS (not all) use embedded operating system. Embedded operating system is embedded in write-proof flash memory, which is not afraid of virus attacks.
So s2200t can be used as a hard disk, but if it is only used to store data, it is somewhat overqualified.
In addition, the difference between server and storage is not as big as expected, and their relationship is more similar to the difference between personal property and personal deposit: personal property should include personal deposit, and personal deposit can reflect personal property to some extent.
