Metro sync disaster recovery (DR) provides two-way synchronous data replication between IBM Spectrum FusionTM HCI clusters installed at two sites. In the event of a site disaster, applications can be failed over to the second site. The replication between the sites is synchronous, hence, the Metro sync DR solution is only available for metropolitan distance data centers with 40 millisecond latency or less. The procedures described in this paper for IBM Spectrum Fusion HCI 2.4 Metro sync DR are the same for IBM Storage Fusion HCI 2.5.2 Metro-DR. This IBM Redpaper publication will help you install and configure the new Metro sync DR function). The use case will show the end to end process with the failover and failback of the WordPress application. IBM Spectrum Fusion HCI and IBM Spectrum Fusion have become IBM Storage Fusion HCI System and IBM Storage Fusion. This edition uses the IBM Spectrum® brand names and will be updated with the next edition.

This IBM® Redbooks® publication offers a short overview of IBM's integrated environment for container workloads, IBM Storage Fusion. The product comes in two variants, IBM Storage Fusion HCI System including all required hardware, and IBM Storage Fusion SDS (software-only) for deployment in public or private Clouds. This paper has been updated with the 2.5.1 release only for IBM Storage Fusion and the 2.5.2 release of IBM Storage Fusion HCI System.

This IBM Redbooks publication is a companion to IBM System Storage Business Continuity: Part 1 Planning Guide, SG24-6547 . We assume that the reader of this book has understood the concepts of Business Continuity planning described in that book. In this book we explore IBM System Storage solutions for Business Continuity, within the three segments of Continuous Availability, Rapid Recovery, and Backup and Restore. We position these solutions within the Business Continuity tiers. We describe, in general, the solutions available in each segment, then present some more detail on many of the products. In each case, the reader is pointed to sources of more information.
