A Networked Storage Systems Based On The PowerPC

With the rapid development of computer technology and network technology, Disks and other storage devices has been difficult mainly on large amounts of data storage and data security requestf. Based on the current pace of development of hard drive technology, is difficult to significantly improve the performance of the disk in the short term, especially in the storage capacity and data security is difficult to have a big breakthrough Widely used network storage technology in data storage, data security and other aspects can be very good to make up for the shortcomings of traditional disk storage technology.The design is based on stability and reliability under harsh environmental systems running applications, power consumption requirements, the development of a network storage system consists of an embedded PowerPC microprocessor and embedded Linux operating system P2020composition. First, this paper describes the current development of network storage systems and mainstream embedded microprocessors, raised the overall design and planning of the network storage system. Then, this paper introduces a hardware platform based on Freescale PowerPC P2020design of network storage systems, including the minimum system, PCI Express to SATA interface module, PCI Express interface card board module FPGA and CPLD control lights and B code time, etc. module. Subsequently, the paper describes the design of embedded Linux operating system-based network storage system software design, including software implementation and management of RAID arrays, NAS and IP-SAN support mixed and WebUI user system management interface of three parts. Finally, this paper describes in detail the performance of the test system, including bandwidth and IOPS under a variety of applications.
