IBM Spectrum Scale V5.0

Software-defined storage improves I/O performance.

IBM Spectrum Scale V5.0 delivers software-defined storage designed to make data storage management simple, efficient, and intelligent at any scale

IBM Spectrum Scale V5.0 is designed to provide performance for an easy, flexible, and data-efficient software-defined storage solution.

As data volumes grow and applications become more capable, more companies need the fast, highly available, and highly scalable data access of Spectrum Scale to drive their business.

Spectrum Scale V5.0 spans the enterprise storage portfolio, including flash, disk, tape, local, and cloud storage.

It delivers enhancements in performance and administrative simplicity with capabilities that are designed to take advantage of the performance of the new generation of storage hardware. For selective workloads running on an NSD server, the number of operations per second is improved approximately three to five times. This version also helps to reduce latency by adopting a protocol that supports sending of messages directly to server memory, eliminating the need for back-and-forth communication previously required to access data.

The settings for several critical system parameters are now automated, delivering optimal tuning for various kinds of workloads. This will provide easier setup and improved performance with less manual configuration. Manual override of the automated settings is readily available for users who prefer to select their own settings.

To better reflect modern storage and workloads and further optimize performance for both large and small block sizes, the new default block size is 4MB, replacing the previous 256KB default. To better support smaller file sizes, sub-block size is variable, depending on the chosen block size. In most laboratory test cases, this configuration showed improved performance simultaneously for both small and large block size workloads compared to the previous version.

Spectrum Scale is designed to provide anytime, anywhere access to data, enabling files and objects to be managed together by means of standardized interfaces such as Posix, OpenStack Swift, NFS, SMB/CIFS, and extended S3 API interfaces, delivering a true data without borders capability for customer environments.

Evolving alongside big data analytics, Spectrum Scale V5.0 supports data sharing for both Hadoop and non-Hadoop applications. It enables users to avoid data replication and movement, helping to improve time to insight, reduce costs, simplify workflows, and add enterprise features to business-critical data repositories. Big data analytics on Spectrum Scale can help reduce costs and increase security with data tiering, encryption, and support across multiple geographies.

Challenge
Today’s data growth is challenging traditional storage and data management solutions. Sources such as new applications and the IoT are generating massive amounts of unstructured data such as video, audio, and text files, and data must be managed across standard and new cloud platforms. Being able to balance traditional workloads with new workloads and data types puts pressure on IT and storage administrators to deliver application performance and reduce data access bottlenecks that delay schedules and waste expensive resources.

Despite the growth in data, storage budgets remain relatively flat as CIOs seek to increase utilization of current storage and decrease the total lifetime cost of data under their management.

Solution
Spectrum Scale can help remove data-related bottlenecks by enabling parallel access to data to eliminate filer choke points or hot spots. It helps simplify data management by providing a single view across an enterprise storage portfolio to scale out simply and quickly. It unifies data silos, including those across multiple geographies.

It is used for diverse workloads across every industry to deliver performance, reliability, and availability of data.
