is a chapter in the OSTEP book by Remzi and Andrea Arpaci-Dusseau that describes the Network File System (NFS) protocol developed by Sun in 1986. More specifically, it describes the NFSv2 protocol. …


” by Hitz, et al., was published in the USENIX Winter Technical Conference in 1994. The paper described the Write Anywhere File Layout (WAFL) file system used by NetApp. NetApp is one of the largest storage providers today and its storage appliances and…


’ by Patterson, Gibson, and Katz was published in SIGMOD 1988. The paper was the result of David Patterson asking Garth Gibson to learn about high performance storage systems and teach the UC Berkeley architects. The paper coined the term RAID and…


’ by Ganger and Patt was published in the first Symposium on Operating Systems Design and Implementation (OSDI) in 1994. The paper proposed one of the many solutions to the problem of crash-consistency of file system metadata. We will begin this summary by describing the…


’ by Rosenblum and Ousterhout was published in ACM Transaction on Computer Systems in 1992. The paper introduced the log-based storage which doubles down on the concept of leveraging faster sequential accesses on disks. Even though the log structured file system (LFS)…


This seemingly low-level detail is used for real impact in systems. For example, Netflix takes into account this discrepancy in the access throughput across inner and outer tracks in their content distribution appliances.

’ by McKusick et al. was published in the journal Transaction on Computer Systems in 1984. It’s take-away message of designing file systems to be aware of the underlying storage medium (HDDs in the case of the fast file system) laid the foundations for file…


’ by Agrawal, et al. was published in USENIX ATC 2008. This was right around the time when solid state disks (SSDs) were starting to become popular as a viable alternative to hard disk drives (HDDs). …


by Ruemmler and Wilkes published in IEEE Computer 1994 describes the components and workings of hard disk drives (HDDs) with the aim of improving disk simulations. Over the years, the workings of HDDs have stayed qualitatively similar even in the face of orders of…
