In the early 90’s, a group at Berkeley led by Professor John Ouster-

file system known as the log-structured file system [RO91]. Their motivation to do so was based on the following observations: • Memory sizes were growing: As memory got bigger, more data could be cached in memory. As more data is cached, disk traffic would increasingly consist of writes, as reads

This paper presents a new technique for disk storage management called a log-structured file system. A logstructured file system writes all modifications to disk sequentially in a log-like structure, thereby speeding up both file writing and crash recovery. The log is the only structure on disk

This paper presents the design and implementation of a transaction manager embedded in a log-structured file system [11]. Measurements show that transaction support on a log-structured file system offers a 10 % performance improvement over transaction support on a conventional, read-optimized file

Research results [ROSE91] demonstrate that a log-structured file system (LFS) offers the potential for dramatically improved write performance, faster recovery time, and faster file creation and deletion than traditional UNIX file systems. This paper presents a redesign and implementation

A log structured file system (LFS) obtains its performance by refraining from seeking for blocks on the disk. Instead, new data is written into new blocks which is placed at the end of the log. This incurs a security issue by leaving data on disk that was supposed to be overwritten. To us

DEC’s business and technology objectives require a strong research program. The Systems Research Center (SRC) and three other research laboratories are committed to filling that need. SRC began recruiting its first research scientists in l984—their charter, to advance the state of knowledge in all

Research results show that while Log-Structured File Systems (LFS) offer the potential for dramatically improved file system performance, the cleaner can seriously degrade performance, by as much as 40 % in transaction processing workloads [9]. Our goal is to examine trace data from live file
