A non-stop operation is possible during problems and disasters with a cluster configuration created by combining FUJITSU Storage ETERNUS SF products with the FUJITSU Storage ETERNUS AF series or ETERNUS DX S4/S3 series. This document provides an overview of the non-stop storage solution and describes its configuration.
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 SF Software for Non-Stop Storage Operation The FUJITSU Storage ETERNUS SF storage software is used by this solution to provide non-stop operation and to handle the operation and management life cycle. With an extensive product range that extends from resource management of storage systems to the provision of additional functions such as replication, it flexibly supports administration of the storage environment and system-wide optimization.

- Storage cost reduction by using compression and high-speed queries ETERNUS SF MA uses Fujitsu's highly efficient data compression for long-term storage of performance and event information. Performance analyses covering long periods of time can be performed quickly using in-memory processing.
FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 2. System Configuration Non-stop storage systems use the transparent failover feature of Storage Cluster. The system is configured with two ETERNUS AF/DX storage systems, the business servers, the Fibre Channel switches, and the management servers running ETERNUS SF products.
FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 2.1. Example of a Non-Stop Storage Configuration 2.1.1. Overview of System Configuration The system uses VMware vSphere 6 for virtualization. Storage Cluster is used to provide duplicate storage systems and vSphere HA is used to provide duplicate ESXi servers for the business servers.
FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 2.1.2. Software Block Diagram This section describes the software used to provide non-stop storage. Business servers VMware vSphere 6.0 is set up on ESXi servers and used for the hypervisor layer.

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.

FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 2.1.4. Overview of Monitoring Server Operation ESF Server is used to manage the storage system (ETERNUS DX200 S4). It handles all aspects of storage operation, including configuration changes, AST settings, and Auto QoS policy settings.
FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series Example of a Non-Stop Storage Configuration (with Redundant Management Servers) 2.2. System Configuration Overview 2.2.1. This configuration is intended to improve the availability of the management servers in a non-stop storage system.
FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 2.3. Hardware Layout Protection against power supply problems or other disasters at the installation site requires that hardware units be physically installed in different sites. Accordingly, install duplicate hardware units in different buildings, on different floors, or in different racks.

FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series System availability can be further improved by providing redundancy for the management servers and by installing them in different sites. The following figure shows a layout in which WSFC is used for management server clustering.
FUJITSU Storage ETERNUS AF series and ETERNUS DX S4/S3 series 2.4. Workflow for System Configuration This section describes the sequence of steps for setting up the example non-stop storage system configurations. When the management servers are configured as VMs on vSphere, the steps to be performed are as shown below (from "Advance preparation"...
