Best Practices For Ds8000 And Z Os Hyperswap With Copy Services Manager

Many IBM® z/OS® customers require their applications to be available 24x7. Whether the business requirements are high availability (HA), disaster recovery (DR), or business continuity, IBM HyperSwap® technology can provide an adequate solution. HyperSwap is the industry standard and is provided as several different implementation options to meet the various business needs of the IBM System z® and z/OS customer base. IBM Copy Services Manager (CSM) enables you to manage z/OS HyperSwap and helps you manage planned and unplanned actions in an z/OS environment from an open systems environment. This IBM Redbooks® publication provides best practices for the planning, implementing, integrating, and managing z/OS HyperSwap with CSM.

This IBM® Redbooks® publication provides an overview of IBM Copy Services Manager (CSM) for IBM Z and open systems, and documents a set of scenarios for using IBM Copy Services manager to automate and manage replication tasks based on IBM Storage. This book reviews and explains the usage of copy services functions and describes how these functions are implemented in IBM Copy Services Manager. IBM Copy Services Manager key concepts, architecture, session types and usage, and new functionality as of IBM Copy Services Manager version 6.1 are also described.

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® Redbooks® publication helps you plan, install, configure, and manage Copy Services on the IBM DS8000® operating in an IBM Z® or Open Systems environment. This book helps you design and implement a new Copy Services installation or migrate from an existing installation. It includes hints and tips to maximize the effectiveness of your installation, and information about tools and products to automate Copy Services functions. It is intended for anyone who needs a detailed and practical understanding of the DS8000 Copy Services. This edition is an update for the DS8900 Release 9.1. Note that the Safeguarded Copy feature is covered in IBM DS8000 Safeguarded Copy, REDP-5506.

This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM Storage DS8900F family. The book provides reference information to assist readers who need to plan for, install, and configure the DS8900F systems. This edition applies to DS8900F systems with IBM Storage DS8000® Licensed Machine Code (LMC) 7.9.30 (bundle version 89.30.xx.x), referred to as Release 9.3. The DS8900F systems are all-flash exclusively, and they are offered as three classes: DS8980F: Analytic Class: The DS8980F Analytic Class offers best performance for organizations that want to expand their workload possibilities to artificial intelligence (AI), Business Intelligence (BI), and machine learning (ML). IBM DS8950F: Agility Class: The Agility Class consolidates all your mission-critical workloads for IBM Z®, IBM LinuxONE, IBM Power, and distributed environments under a single all-flash storage solution. IBM DS8910F: Flexibility Class: The Flexibility Class reduces complexity while addressing various workloads at the lowest DS8900F family entry cost. The DS8900F architecture relies on powerful IBM POWER9TM processor-based servers that manage the cache to streamline disk input/output (I/O), which maximizes performance and throughput. These capabilities are further enhanced by High-Performance Flash Enclosures (HPFE) Gen2. Like its predecessors, the DS8900F supports advanced disaster recovery (DR) solutions, business continuity solutions, and thin provisioning.

IBM® z/OS® Global Mirror (zGM), also known as Extended Remote Copy (XRC), is a combined hardware and software solution that offers the highest levels of continuous data availability in a disaster recovery (DR) and workload movement environment. Available for the IBM DS8000® Storage System, zGM provides an asynchronous remote copy solution. This IBM RedpaperTM publication takes you through best practices for planning, tuning, operating, and monitoring a zGM installation. This publication is intended for clients and storage administrators who need to understand and maintain a zGM environment.

This IBM® RedpaperTM 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.
