随着存储技术的迅速发展，存储业务需求的不断增长，独立的磁盘冗余阵列可利用多个磁盘并行存取提高存储系统的性能。磁盘阵列技术采用硬件和软件两种方式实现，软件RAID（Redundant Array of Independent Disks）主要利用操作系统提供的软件实现磁盘冗余阵列功能，对系统资源利用率高，节省成本。硬件RAID将大部分RAID功能集成到一块硬件控制器中，系统资源占用率低，可移植性好。 分析了软件RAID的性能瓶颈，使用硬件直接完成部分计算提高软件RAID性能。针对RAID5采用FPGA（Field Programmable Gate Array）技术实现RAID控制器硬件设计，完成磁盘阵列启动、数据缓存（Cache）以及数据XOR校验等功能。基于硬件RAID的理论，提出一种基于Virtex-4的硬件RAID控制器的系统设计方案：独立微处理器和较大容量的内存；实现RAID级别迁移，在线容量扩展，在线数据热备份等高效、用户可定制的高级RAID功能；利用Virtex-4内置硬PowerPC完成RAID服务器部分配置和管理工作，运行Linux操作系统、RAID管理软件等。控制器既可以作为RAID控制卡在服务器上使用，也可作为一个独立的系统，成为磁盘阵列的调试平台。 随着集成电路的发展，芯片的体积越来越小，电路的布局布线密度越来越大，信号的工作频率也越来越高，高速电路的传输线效应和信号完整性问题越来越明显。RAID控制器属于高速电路的范畴，在印刷电路板（Printed Circuit Block, PCB）实现时分别从叠层设计、布局、电源完整性、阻抗匹配和串扰等方面考虑了信号完整性问题，并基于IBIS（I/O BUFFER Information Specification）模型进行了信号完整性分析及仿真。

A frequent requirement in systems involves drivinganalog signals into non-linear or reactive loads. Cables,transformers, actuators, motors and sample-hold circuitsare examples where the ability to drive diffi cult loads isrequired. Although several power BUFFER amplifi ers areavailable, none have been optimized for driving diffi cultloads.

The CAT25128 is a 128−Kb Serial CMOS EEPROM device internally organized as 16Kx8 bits. This features a 64−byte page write BUFFER and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25128 device. The device featuressoftware and hardware write protection, including partial as well as full array protection.

The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are orientedin the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic inputand output BUFFER separated by TI’s silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to4000 V. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, andprevent noise currents on a data bus or other circuits from entering the local ground and interfering with ordamaging sensitive circuitry.
