Updated for R8.51 This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM DS8880 family. The book provides reference information to assist readers who need to plan for, install, and configure the DS8880 systems. The IBM DS8000® family is a high-performance, high-capacity, highly secure, and resilient series of disk storage systems. The DS8880 family is the latest and most advanced of the DS8000 offerings to date. The high availability, multiplatform support, including IBM Z, and simplified management tools help provide a cost-effective path to an on-demand and cloud-based infrastructures. The IBM DS8880 family now offers business-critical, all-flash, and hybrid data systems that span a wide range of price points: DS8882F: Rack Mounted storage system DS8884: Business Class DS8886: Enterprise Class DS8888: Analytics Class The DS8884 and DS8886 are available as either hybrid models, or can be configured as all-flash. Each model represents the most recent in this series of high-performance, high-capacity, flexible, and resilient storage systems. These systems are intended to address the needs of the most demanding clients. Two powerful IBM POWER8® processor-based servers manage the cache to streamline disk I/O, maximizing performance and throughput. These capabilities are further enhanced with the availability of the second generation of high-performance flash enclosures (HPFEs Gen-2) and newer flash drives. Like its predecessors, the DS8880 supports advanced disaster recovery (DR) solutions, business continuity solutions, and thin provisioning. All disk drives in the DS8880 storage system include the Full Disk Encryption (FDE) feature. The DS8880 can automatically optimize the use of each storage tier, particularly flash drives, by using the IBM Easy Tier® feature. Release 8.5 introduces the Safeguarded Copy feature. The DS8882F Rack Mounted is decribed in a separate publication, Introducing the IBM DS8882F Rack Mounted Storage System, REDP-5505.

This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM System Storage® DS8700 storage subsystem. This book has reference information that will help you plan for, install, and configure the DS8700 and also discusses the architecture and components. The DS8700 is the most advanced model in the IBM System Storage DS8000® series. It includes IBM POWER6®-based controllers, with a dual 2-way or dual 4-way processor complex implementation. Its extended connectivity, with up to 128 Fibre Channel/FICON® ports for host connections, make it suitable for multiple server environments in both open systems and IBM System z® environments. If desired, the DS8700 can be integrated in an LDAP infrastructure. The DS8700 supports thin provisioning. Depending on your specific needs, the DS8700 storage subsystem can be equipped with SATA drives, FC drives, and Solid® State Drives (SSDs). The DS8700 can now automatically optimize the use of SSD drives through its no charge Easy Tier feature. The DS8700 also supports Full Disk Encryption (FDE) feature. Its switched Fibre Channel architecture, dual processor complex implementation, high availability design, and the advanced Point-in-Time Copy and Remote Mirror and Copy functions that incorporates make the DS8700 storage subsystem suitable for mission-critical business functions.

The IBM® System Storage® DS8000® offers a policy-based resource management capability. This capability, named resource groups or Copy Services scope management, is the topic of this paper. With Copy Services scope management, Copy Service relationships can be limited to the domain of a set of user-specified resources. Additionally, user IDs can be configured to only allow them to issue Copy Services requests against a specific domain. This capability facilitates multi-tenancy by preventing any host or user from initiating a Copy Services operation that would cross a specific tenant's domain boundaries. In addition to the multi-tenant capability, Copy Services domains can also provide general-purpose partitioning to isolate heterogeneous environments from each other. The Copy Services scope management capability is available for any host type on any volume type. This IBM RedpaperTM publication is intended for anyone interested in Copy Services scope management. The paper starts with a general overview of the Copy Services scope management capability, its intended usage, and explanations of the underlying concept of resource groups. Subsequent chapters provide implementation details for both open systems and System z® perspectives and include usage illustrations with the DS8000 command-line interface (DSCLI).

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® RedpaperTM publication describes the concepts and functions of IBM System Storage® Easy Tier®, and explains its practical use with the IBM DS8000® series and License Machine Code 7.9.0.xxx (also known as R9.0).. Easy Tier is designed to automate data placement throughout the storage system disks pool. It enables the system to (automatically and without disruption to applications) relocate data (at the extent level) across up to three drive tiers. The process is fully automated. Easy Tier also automatically rebalances extents among ranks within the same tier, removing workload skew between ranks, even within homogeneous and single-tier extent pools. Easy Tier supports a Manual Mode that enables you to relocate full volumes. Manual Mode also enables you to merge extent pools and offers a rank depopulation function. Easy Tier fully supports thin-provisioned Extent Space Efficient fixed block (FB) and count key data (CKD) volumes in Manual Mode and Automatic Mode. Easy Tier also supports extent pools with small extents (16 MiB extents for FB pools and 21 cylinders extents for CKD pools). Easy Tier also supports high-performance and high-capacity flash drives in the High-performance flash enclosure, and it enables additional user controls at the pool and volume levels. This paper is aimed at those professionals who want to understand the Easy Tier concept and its underlying design. It also provides guidance and practical illustrations for users who want to use the Easy Tier Manual Mode capabilities. Easy Tier includes additional capabilities to further enhance your storage performance automatically: Easy Tier Application, and Easy Tier Heat Map Transfer.

With the availability of the IBM® Storage Driver for OpenStack, the IBM DS8000® can offer a range of capabilities that enable more effective storage automation deployments to private or public clouds. Enabling OpenStack with DS8000 allows storage to be made available whenever it is needed without the traditional associated cost of highly skilled administrators and infrastructure. This IBM RedpaperTM publication explains how to integrate the DS8000 in an OpenStack environment, first from the DS8000 Storage Administrator perspective and then from a cloud administrator standpoint. This paper also contains practical examples and illustrations of DS8000 functions that can be used with OpenStack, as it applies for DS8880 Release 8.3 and the OpenStack Pike release.
