This IBM® Redpaper publication helps you design and implement a 4-site replication solution for IBM DS8000® environments. IBM Copy Services Manager is used to orchestrate the data replication and failover and failback mechanisms between the different sites. The IBM DS8000 Copy Services functions are the foundation of this 4-site replication solution. The four sites consist of two pairs of sites. Within each pair, the two sites are at metro distance, while the pairs connect at long distance over asynchronous links. The solution is based on a Multi-Target PPRC topology that consists of a Metro Mirror replication to the secondary site in the local region and a Global Mirror replication to the third site in the remote region. The fourth site is set up as a cascaded Global Copy, which is an asynchronous copy.

This IBM® Redpaper™ publication reviews the architecture and operations of the IBM DS8000® Global Mirror function. The document looks at different aspects of the solution in terms of performance, infrastructure requirements, data integrity, business continuity, and impact on production. Hints and tips are provided on how to best configure the overall Global Mirror environment, in terms of connectivity, storage configuration, and specific parameters tuning. The guidelines that are provided are in general related to performance, which ultimately ensures a better recovery point objective (RPO). Therefore, we encourage you to follow those guidelines.

This IBM® Redbooks® publication describes data migrations between IBM DS8000® storage systems, where in most cases one or more older DS8000 models are being replaced by the newer DS8870 model. Most of the migration methods are based on the DS8000 Copy Services. The book includes considerations for solutions such as IBM Tivoli® Productivity Center for Replication and the IBM Geographically Dispersed Parallel Sysplex™ (GDPS®) used in IBM z/OS® environments. Both offerings are primarily designed to enable a disaster recovery using DS8000 Copy Services. In most data migration cases, Tivoli Productivity Center for Replication or GDPS will not directly provide functions for the data migration itself. However, this book explains how to bring the new migrated environment back into the control of GDPS or Tivoli Productivity Center for Replication. In addition to the Copy Services based migrations, the book also covers host-based mirroring techniques, using IBM Transparent Data Migration Facility (TDMF®) for z/OS and the z/OS Dataset Mobility Facility (zDMF).

In today’s highly competitive and real-time environment, the ability to manage all IT operations on a continuous basis makes the creation of copies and backups of data a core requirement for any IT deployment. Furthermore, it is necessary to provide proactive efficient disaster recovery strategies that can ensure continuous data availability for business operations. The Copy Services functions available with the IBM® System Storage® DS8000® are part of these strategies. This IBM Redbooks® publication helps you plan, install, configure, and manage the Copy Services functions of the DS8000 when they are used in Open System and IBM i environments. This book provides the details necessary to implement and control each of the Copy Services functions. Numerous examples illustrate how to use the various interfaces with each of the Copy Services. This book also covers the 3-site Metro/Global Mirror with Incremental Resync feature and introduces the IBM Tivoli® Storage Productivity Center for Replication solution. This book should be read with The IBM System Storage DS8000 Series: Architecture and Implementation, SG24-8886. There is also a companion book, IBM System Storage DS8000 Copy Services for IBM System z®, SG24-6787, which supports the configuration of the Copy Services functions in IBM z/OS® environments.

Data migration has become a mandatory and regular activity for most data centers. Companies need to migrate data not only when technology needs to be replaced, but also for consolidation, load balancing, and disaster recovery. This IBM Redbooks® publication addresses the aspects of data migration efforts while focusing on the IBM System Storage® as the target system. Data migration is a critical and complex operation, and this book provides the phases and steps to ensure a smooth migration. Topics range from planning and preparation to execution and validation. The book also reviews products and describes available IBM data migration services offerings. It explains, from a generic standpoint, the appliance-based, storage-based, and host-based techniques that can be used to accomplish the migration. Each method is explained including the use of the various products and techniques with different migration scenarios and various operating system platforms. This document targets storage administrators, storage network administrators, system designers, architects, and IT professionals who design, administer or plan data migrations in large data Centers. The aim is to ensure that you are aware of the current thinking, methods, tools, and products that IBM can make available to you. These items are provided to ensure a data migration process that is as efficient and problem-free as possible. The material presented in this book was developed with versions of the referenced products as of June 2011.

This IBM Redbooks publication helps you install, tailor, and configure Copy Services in open systems environments on the IBM System Storage DS6000 storage server series. It should be read in conjunction with the IBM System Storage DS6000 Series: Architecture and Implementation, SG24-6781. This book gives you the details necessary to configure each of the Copy Services functions in an open systems environment. There is a companion book that supports the configuration of the Copy Services functions in a z/OS environment, IBM System Storage DS6000 Series: Copy Services with System z servers, SG24-6782. This book helps you design and create the storage map and install Copy Services in an open systems environment. This book helps you design and create a new Copy Services installation or to migrate from an existing installation, as well as addresses design functions and changes in terminology from other IBM Copy Services products. We include hints and tips to maximize the effective installation. It also includes a section on System i and an overview of the TotalStorage Productivity Center for Replication.
