single.dvi 44 Flash-based SSDs After decades of hard-disk drive dominance, a new form of persistent storage device has recently gained significance in the world. Generi- cally referred to as solid-state storage, such devices have no mechani- cal or moving parts like hard drives; rather, they are simply built out of transistors, much like memory and

single.dvi 29 Lock-based Concurrent Data Structures Before moving beyond locks, we’ll first describe how to use locks in some common data structures. Adding locks to a data structure to make it us- able by threads makes the structure thread safe. Of course, exactly how such locks are added determines both the correctness and performance of

single.dvi 45 Data Integrity and Protection Beyond the basic advances found in the file systems we have studied thus far, a number of features are worth studying. In this chapter, we focus on reliability once again (having previously studied storage system reliabil- ity in the RAID chapter). Specifically, how should a file system or storage

single.dvi 41 Locality and The Fast File System When the UNIX operating system was first introduced, the UNIX wizard himself Ken Thompson wrote the first file system. Let’s call that the “old UNIX file system”, and it was really simple. Basically, its data structures looked like this on the disk: S Inodes Data The super

single.dvi 40 File System Implementation In this chapter, we introduce a simple file system implementation, known as vsfs (the Very Simple File System). This file system is a simplified version of a typical UNIX file system and thus serves to introduce some of the basic on-disk structures, access methods, and various policies that you will

single.dvi 42 Crash Consistency: FSCK and Journaling As we’ve seen thus far, the file system manages a set of data structures to implement the expected abstractions: files, directories, and all of the other metadata needed to support the basic abstraction that we expect from a file system. Unlike most data structures (for example, those found

single.dvi 55 Access Control Chapter by Peter Reiher (UCLA) 55.1 Introduction So we know what our security goals are, we have at least a general sense of the security policies we’d like to enforce, and we have some ev- idence about who is requesting various system services that might (or might not) violate our policies.
