This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM System Storage® DS8870 storage system. The book provides reference information to assist readers who need to plan for, install, and configure the DS8870. The IBM System Storage DS8870 is the most advanced model in the IBM DS8000® series and is equipped with IBM POWER7® based controllers. Various configuration options are available that scale from dual 2-core systems up to dual 16-core systems with up to 1 TB of cache. The DS8870 also features enhanced 8 Gbps device adapters and host adapters. Connectivity options, with up to 128 Fibre Channel/IBM FICON® ports for host connections, make the DS8870 suitable for multiple server environments in open systems and The DS8870 supports advanced disaster recovery solutions, business continuity solutions, and thin provisioning. All disk drives in the DS8870 storage system have the Full Disk Encryption (FDE) feature. The DS8870 also can be integrated in a Lightweight Directory Access Protocol (LDAP) infrastructure. The DS8870 is equipped with high-density storage enclosures and can be equipped with solid-state drives (SSDs). The DS8870 can automatically optimize the use of each storage tier, particularly SSDs through the IBM Easy Tier® feature, which is available at no extra charge. With Licensed Machine Code 7.7.10.xx.xx, Easy Tier offers new features, still at no charge.

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.
