Storage server can be seen as a more powerful, larger PC, hardware is mainly composed of CPU, motherboard, memory, hard disk and so on. The NAS network memory is a special data storage server equipment, it must have the characteristics of strong processing ability, high stability, reliability, security, expansibility and so on, and it is different from ordinary PC.
Especially in the construction of hardware structure network, storage module two aspects, mainly have the following characteristics:
1.The data storage module mainly provides support for IDE / EIDEN SCSI, bus technology, industrial standard EIDE controller, array controller, so that the system can connect any kind of equipment, such as optical disc tower, disk array and so on.
2、In fact, the network control module realizes the function of network adapter, which is used for data frame generation, identification and transmission, data compilation, address decoding, data transmission error detection and hardware fault detection, etc. It ultimately provides a common network port and a high-speed fiber channel connection port, providing 100MB: or higher rates, so that the system can be easily connected to Ethernet or hooked up to the high-speed fiber channel connected to the SAN. The CACHE / Rom / RAM module provides the system with a cache / RAM space. The system core operating system and related system software can be solidified on ROM or FLASH/FLASH, and the program in ROM/FLASH can be booted directly when the system starts.
