Network-Attached Secure Disks (NASD)

Date: April 20, 1995

Abstract: The network-attached, autonomous disk drive revolutionizes disk drive and file system technologies. It removes the server workstation bottleneck from networked file systems, embeds the file system into the disk drive and promotes the disk to a first class network device. By integrating security into the drive, network-attached disk drives provide file system integrity that is not dependant on the trustworthiness of the client. Minimizing the latency between disk drive and network is achieved by utilizing a low-power, low-cost, high-bandwidth embedded architecture specifically designed for data movement. Direct attachment to a network means that the disk drive can serve as a fundamental building block for highly-reliable, highly-available and fault-tolerant file systems providing low-cost, high-performance storage to meet the rapidly increasing needs of digital data storage applications.
