Scale Out Network Attached Storage

IBM Scale Out Network Attached Storage (SONAS)

The IBM® SONAS is an enterprise class network-attached storage system designed to offer scale-out performance, capacity and a very high utilisation rate. It is designed as a single global repository to manage multiple petabytes(PB) of storage and up to a billion files under a single file system securely and efficiently. It provides policy-driven file lifecycle management driven by a robust policy engine and automated storage tiering (disk and tape) for operational efficiency, ease of management and cost savings.


15 PBs


Up to one billion files in a single global file system and up to 256 global file systems; simplified management of PB of storage; linear scaling of performance; robust, automated tiered storage and lifecycle management; backend tape support for long-term cost savings; robust asynchronous replication for business continuity and disaster recovery(DR); leverage as a SONAS gateway for IBM Storwize V7000, IBM System Storage DCS3700 and IBM XIV Storage System


Seamlessly integrates with IBM SmartCloud Storage Access for self-service capacity provisioning; includes ability to report usage and access patterns for chargeback; enable global clouds with IBM Active Cloud Engine
