IBM Storage Scale Software – Product Review

Storage Scale software is offered by IBM to meet large-scale file storage requirements. Storage Scale uses GPFS installed on servers with either captive storage or attached to all flash external or disk-based storage systems. Storage Scale software may be used with other available storage systems and servers. The clustered distributed file system GPFS allows multiple nodes in a configuration. A global namespace for access to large numbers of files is a key feature. Standard hardware and software are integrated to provide the systems and advanced features.

The IBM Storage Scale is also offered as Storage Scale System (formerly ESS) which integrates standard hardware and software elements to provide file storage over standard protocols. The standard hardware includes IBM Power server systems with internal or external disks systems. The software elements include the General Parallel File System and Storage Protect (Tivoli Storage Manager). IBM Storage Scale System has been certified as a storage target for HortonWorks Data Platform.

The Storage Scale Erasure Code Edition adds IBM Storage Scale RAID software in order to provide Reed-Solomon de-clustered Erasure Coding that protects against drive and node failures, similar to the functionality seen in Storage Scale System. There are multiple editions of the Storage Scale software which are detailed in the Evaluator Group Product Analysis document.

Object access is supported with the incorporation of Swift open source software installed on GPFS nodes. Objects are stored as files within GPFS. The extended S3 API for Swift is added to support applications written for S3 and AWS.
