    FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 1. Overview of Non-Stop Storage Solution Redundancy has long been adopted for servers, with this also providing redundancy for any internal hard disks in the server. While configurations such as the shared disks in cluster systems or server virtualization have involved servers using external disk storage, redundancy for the storage systems themselves has relied on the server software and its use has remained limited.

    FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 2.1.3. Overview of Business Server Operation This section describes how the business servers work with non-stop storage. The storage system (ETERNUS DX200 S4) is clustered at the storage system layer. If a failure occurs on the Primary storage, the storage connected to the servers is switched over automatically by making the Secondary storage active.
