IBM DS8870 Architecture and Implementation (Release 7.5)

By: Bertrand Dufrasne,Werner Bauer,Artur Borowicz,Adrian Orben,Robert Tondini,Bob Xiao,IBM Redbooks

This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM DS8870. The WhitepaperRedpaperbook provides reference information to assist readers who need to plan for, install, and configure the DS8870. The IBM DS8870 is the most advanced model in the IBM DS8000® series and is equipped with IBM POWER7+TM 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 features an integrated High-Performance Flash Enclosure (HPFE) with flash cards that can deliver up to 250,000 IOPS and up to 3.4 GBps bandwidth. A High-Performance All-Flash configuration is also available. The DS8870 now features 16 Gbps 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 IBM zTM Systems environments. DS8870 Release 7.5 brings new and enhanced IBM z SystemsTM synergy features. These features are covered in detail in IBM DS8870 and IBM z Systems Synergy, REDP-5186. 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 can automatically optimize the use of each storage tier, particularly flash drives and flash cards, through the IBM Easy Tier® feature, which is available at no extra charge. This edition applies the IBM DS8870 Release 7.5.

IBM DS8870 Easy Tier Heat Map Transfer

By: Bert Dufrasne,Artur Borowicz,IBM Redbooks

This IBM® RedpaperTM publication describes the concepts, functions, and practical usage of IBM Easy Tier® Heat Map Transfer (HMT). IBM System Storage® DS8000® Easy Tier is designed to automate data placement throughout the storage system disks pool. Easy Tier generates a heat map. It is a workload activity metric for each extent in a logical volume. With Easy Tier HMT, it is possible to transfer the heat map from a mirrored primary site and reapply it periodically at secondary and tertiary sites by using the Easy Tier Heat Map Transfer Utility (HMTU). This capability helps maintain storage performance after a failover to a remote site. With DS8870 Release 7.5, the heat map transfer supports Metro Global Mirror (MGM) replication topology in addition to Metro Mirror/Global Copy/Global Mirror (MM/GC/GM) functions. This paper is for those professionals who want to understand the Easy Tier HMT concept and its underlying design. It also provides guidance and practical illustrations about the operation of the HMTU. For more information about the general concept of Easy Tier, see IBM DS8000 Easy Tier, REDP-4667. For more information about Easy Tier Server and Easy Tier Application, see the following publications: IBM System Storage DS8000 Easy Tier Server, REDP-5013 DS8870 Easy Tier Application, REDP-5014
