Objectives. Describe the physical structure of secondary and tertiary storage devices and the resulting effects on the uses of the devices. Explain the performance characteristics of mass-storage devices. Discuss operating-system services provided for mass storage, including RAID and HSM. Operating System Concepts Essentials – 8th.
A network-attached storage (NAS) device is a special-purpose storage system that is accessed remotely over a network. Implemented via remote procedure calls (RPCs) between host and storage over typically TCP or UDP on IP network, such as NFS for UNIX systems and CIFS for Window machines.
Mass-storage structure: Overview of Mass-storage structure, Disk structure, Disk attachment, Disk scheduling, Swap-space management, RAID structure, Stab e-storage implementation.

Disk Speed. To read from disk, we must specify: cylinder #, surface #, sector #, transfer size, memory address. Disk speed has two parts: Transfer rate: the rate at which data flow between the drive and the computer. Positioning time: Seek time: the time to move the disk arm to the desired cylinder. Rotational latency: the time for the desired ...
