摘要
RAID (廉价磁盘冗余阵列 )技术是提高存储子系统性能和可靠性的一种有效手段。RAID可以由软件或硬件实现 ,硬件RAID又可以分为主机内部硬件RAID和主机外部硬件RAID。硬件RAID不依赖操作系统 ,具有比软件RAID更高的运行效率和容错能力。主机内部硬件RAID又比主机外部硬件RAID具有更高的运行效率和管理能力。主机内部硬件RAID广泛应用于高端网络服务器中。以MylexDAC960PCIRAID适配器 (主机内部硬件RAID控制器 )为例 ,对主机内部硬件RAID的基本概念、安装和配置、以及故障后的重建进行介绍。
RAID (Inexpensive Disk Redundancy Array) technology is an effective means to enhance performance and reliability of storage subsystem. RAID can be implemented with software or hardware, and hardware RAID can also be divided into host-based RAID and SCSI-SCSI RAID. Hardware RAID is not dependent upon operating system, having higher operating efficiency and fault-tolerant capability than software RAID. Host-based RAID has higher operation efficiency and better management capability than SCSI-to-SCSI RAID . Host-based RAID is widely applied to high-end network server. This paper uses Mylex DAC 960 PCI RAID adapter (controller of host-based RAID) as an example to introduce the basic concept of host-based RAID and its installation and configuration as well as its rebuilding after failure.
