Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

Tags: storage, ubuntu •
Comments: 0 Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04 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 Ubuntu 12.04) with GlusterFS. The client system (Ubuntu 12.04 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.
