Abstract
The invention discloses an IP (Internet Protocol) SAN (Storage Area Network) storage device and a storage method thereof, and belong to the field of SAN storage. The invention aims to solve the technical problem how to replace a high-cost optical fiber, reduce cost and meanwhile, achieve an SAN. The invention adopts the technical scheme that (1) the IP SAN storage device comprises a hardware platform and a software management system, the hardware platform comprises a circuit board, a power supply management unit, a signal management unit, a storage control unit and an external interface unit are arranged on the circuit board, and the software management system comprises a bottom driving module and a top management module; and (2) the storage method of the IP SAN storage device comprises: 1, carrying out CPLD (Complex Programmable Logic Device) time sequence control by a power-on time sequence module of the bottom driving module so as to achieve clock control, CPU (Central Processing Unit) power-on, Flash chip selection and software resetting; 2, reading bootloader by a bootloader module, and simultaneously, reading CPU hardware configuration, clock configuration and memory configuration.
Description
technical field [0001] The invention relates to the field of SAN storage, in particular to an IPSAN storage device and a storage method thereof. Background technique [0002] The birth of SAN (full name StorageAreaNetwork, storage area network) makes storage space more fully utilized and makes installation and management more effective. SAN is a technology that integrates storage devices, connection devices and interfaces in a high-speed network. SAN itself is a storage network that undertakes the task of data storage. The SAN network is isolated from the LAN service network, and the storage data flow will not occupy the service network bandwidth. In a SAN network, all data transmission is carried out in a high-speed, high-bandwidth network. SAN storage implements block-level storage access directly to physical hardware, which improves storage performance and upgrade capabilities. The early SAN used Fiber Channel (FC, FiberChannel) technology, so the previous SAN mostly re...
