Abstract
New IBM Spectrum Scale for Linux on z Systems is an extremely powerful file system that is based on the IBM General Parallel File System (GPFS™) technology, which is a proven, scalable, high-performance data and file management solution, and it is also enabled for technical computing, Big Data & Analytics, and Cloud.
IBM Spectrum Scale for Linux on z Systems is being used extensively across multiple industries worldwide to provide simplified data management and integrated information lifecycle tools capable of managing petabytes of data and billions of files, in order to arrest the growing cost of managing ever growing amounts of data. This IBM Redbooks® Solution Guide describes the benefits of IBM Spectrum Scale for Linux on z Systems.

IBM Spectrum Scale for Linux on IBM® z Systems® is an extremely powerful file system. It is based on the IBM General Parallel File System (GPFS™) technology, which is a proven, scalable, high-performance data and file management solution, and also enabled for technical computing, Big Data & Analytics, and Cloud. IBM Spectrum Scale is being used extensively across multiple industries worldwide. This IBM Redbooks® Solution Guide describes the benefits of IBM Spectrum Scale.
Did you know?
IBM Spectrum Scale for Linux on z Systems supports extended count key data (IBM ECKD™) direct access storage device (DASD) disks and Fibre Channel Protocol (FCP) attached Small Computer System Interface (SCSI) disks.
IBM Spectrum Scale for Linux on z Systems nodes can communicate with each other through HiperSockets devices within one z Systems server, which provides high-speed IP network communication. Therefore, it can have better file system performance, especially in Network Shared Node (NSD) mode. The HiperSockets devices in two z Systems servers can be connected through a HiperSockets Bridge.
Each clustered file system has metadata. Some clustered file systems require a centralized metadata server, which can become a performance bottleneck for metadata-intensive operations and can represent a single point of failure. IBM Spectrum Scale solves this problem by managing metadata at the node that is using the file or, in the case of concurrent access to the file, at a dynamically selected node that is using the file.
Business value
Today’s data growth is challenging traditional storage and data management solutions. Limited data access, good performance, and reliability are required for IT environments. Also, application performance is affected by data access bottlenecks that delay schedules and waste expensive resources. Workloads are scaled up to large numbers of application nodes and disks, and because not all components are working correctly at all times, IT environments are required to handle component failures and continue the operation.
IBM Spectrum Scale for Linux on z Systems will enable enterprise clients to use a highly available clustered file system with Linux in a logical partition (LPAR) or as a Linux guest on IBM z/VM®.
IBM and independent software vendor (ISV) solutions will provide higher value for Linux on z Systems clients by exploiting IBM Spectrum Scale functionality:
