FPO is suitable for workloads with high data locality such as shared nothing database clusters such as SAP HANA and DB2 DPF, and can be used as a HDFS-compatible filesystem. This allows it to use locally attached disks on a cluster of network connected servers rather than requiring dedicated servers with shared disks (e.g. This was officially released with GPFS 3.5 in December 2012, and is now known as FPO In 2010, IBM previewed a version of GPFS that included a capability known as GPFS-SNC, where SNC stands for Shared Nothing Cluster. Since inception, it has been successfully deployed for many commercial applications including digital media, grid analytics, and scalable file services. Today it is used by many of the top 500 supercomputers listed on the Top 500 Supercomputing List. GPFS has been available on IBM's AIX since 1998, on Linux since 2001, and on Windows Server since 2008. The main difference between the older and newer filesystems was that GPFS replaced the specialized interface offered by Vesta/PIOFS with the standard Unix API: all the features to support high performance parallel I/O were hidden from users and implemented under the hood. Vesta was commercialized as the PIOFS filesystem around 1994, and was succeeded by GPFS around 1998. The disjoint sequences are arranged to correspond to individual processes of a parallel application, allowing for improved scalability. The partitioning is such that it abstracts away the number and type of I/O nodes hosting the filesystem, and it allows a variety of logically partitioned views of files, regardless of the physical distribution of data within the I/O nodes. With partitioning, a file is not a sequence of bytes, but rather multiple disjoint sequences that may be accessed in parallel. Vesta introduced the concept of file partitioning to accommodate the needs of parallel applications that run on high-performance multicomputers with parallel I/O subsystems. Īnother ancestor is IBM's Vesta filesystem, developed as a research project at IBM's Thomas J. This design turned out to be well suited to scientific computing. Tiger Shark was initially designed to support high throughput multimedia applications. GPFS began as the Tiger Shark file system, a research project at IBM's Almaden Research Center as early as 1993. In addition to providing filesystem storage capabilities, it provides tools for management and administration of the GPFS cluster and allows for shared access to file systems from remote clusters. It can be used with AIX clusters, Linux clusters, on Microsoft Windows Server, or a heterogeneous cluster of AIX, Linux and Windows nodes running on x86, Power or IBM Z processor architectures. Like typical cluster filesystems, GPFS provides concurrent high-speed file access to applications executing on multiple nodes of clusters. The storage filesystem called Alpine has 250 PB of storage using Spectrum Scale on IBM ESS storage hardware, capable of approximately 2.5TB/s of sequential I/O and 2.2TB/s of random I/O. Summit is a 200 Petaflops system composed of more than 9,000 POWER9 processors and 27,000 NVIDIA Volta GPUs. įor example, it is the filesystem of the Summit Īt Oak Ridge National Laboratory which was the #1 fastest supercomputer in the world in the November 2019 TOP500 list of supercomputers. It is used by many of the world's largest commercial companies, as well as some of the supercomputers on the Top 500 List. It can be deployed in shared-disk or shared-nothing distributed parallel modes, or a combination of these. GPFS ( General Parallel File System, brand name IBM Spectrum Scale) is high-performance clustered file system software developed by IBM. High-performance clustered file system GPFS Developer(s)
