Abstract
In computer systems today, speed and responsiveness is often determined by network and storage subsystem per-formance. Faster, more scalable networking interfaces like Fibre Channel and Gigabit Ethernet provide the scaf-folding from which higher performance implementations may be constructed, but new thinking is required about how machines interact with network-enabled storage de-vices. We have developed a Linux file system called GFS (the Global File System) that allows multiple Linux machines to access and share disk and tape devices on a Fibre Chan-nel or SCSI storage network. We plan to extend GFS by transporting packetized SCSI commands over IP so that any GFS-enabled Linux machine can access shared net-work devices. GFS will perform well as a local file sys-tem, as a traditional network file system running over IP, and as a high-performance cluster file system running over storage networks like Fibre Channel. GFS device shar-ing provides a key cluster-enabling technology for Linux, helping to bring the availability, scalability, and load bal-ancing benefits of clustering to Linux. Our goal is to develop a scalable, (in number of clients and devices, capacity, connectivity, and band-width) server-less file system that integrates IP-based net-work attached storage (NAS) and Fibre-Channel-based storage area networks (SAN). We call this new architec-ture Storage Area InterNetworking (SAINT). It exploits the speed and device scalability of SAN clusters, and pro-vides the client scalability and network interoperability of NAS appliances. Our Linux port shows that the GFS architecture is portable across different platforms, and we are currently working on a port to NetBSD. The GFS code is open source (GPL) software freely available on the Internet at
