When you say "log-structured file system," most storage developers will immediately think of Ousterhout and Rosenblum's classic paper, The Design and Implementation of a Log-structured File System - and the nearly two decades of subsequent work attempting to solve the nasty segment cleaner problem (see below) that came with it.

Relational databases define a strict structure and provide a rigid way to maintain data for a software application. Apache's open source CouchDB offers a new method of storing data, in what is referred to as a schema-free document-oriented database model.

Big Table is an ongoing research project to create a structured database that will operate in a distributed environment. It is a distributed storage system for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers.

Data storage has become the weak link in enterprise applications, and without a concerted effort on the part of storage vendors, the technology is in danger of becoming irrelevant

It was with delight that I read these words on Thursday: "The proposed IndexedDB standard, which provides a local database store for Web applications, will be supported by Firefox 4."

Linux is the Swiss Army knife of file systems, and it also offers a wide variety of storage technologies for both desktops and servers. Beyond the file system, Linux incorporates world-class NAS and SAN technologies, data protection, storage management, support for clouds, and solid-state storage. Learn more about the Linux storage ecosystem and why it's number one in server market share.

This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 12.10 as well) will be able to access the storage as if it was a local filesystem.

This tutorial shows how to set up a high-availability storage with two storage servers (CentOS 6.3) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (CentOS 6.3 as well) will be able to access the storage as if it was a local filesystem.

This tutorial shows how to set up a high-availability storage with two storage servers (CentOS 5.4) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (CentOS 5.4 as well) will be able to access the storage as if it was a local filesystem.
