Striping Across Four Storage Nodes With GlusterFS On Debian Lenny

Post date: July 12, 2009, 10:07 Category: Installing Views: 3650 Comments
Tutorial quote: This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Debian Lenny) with GlusterFS. The client system (Debian Lenny as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 servers with SATA-II RAID and Infiniband HBA.

Tutorial quote: It is so convenient to take pictures on digital cameras that (it has been argued) we are all becoming better photographers: we take more pictures and therefore are able to choose only the best for printing and sharing. It is easy to experiment, see the results quickly, and share them with friends. The Internet makes sharing photographs very simple and a lot of fun.
