Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 SysplexTM (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).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2021-03-08 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IBM® DS8000® series includes the option to replace the locally based user ID and password authentication with a centralized directory-based approach. This IBM Redpaper publication helps DS8000 storage administrators understand the concepts and benefits of a centralized directory. It provides the information that is required for implementing a DS8000 authentication mechanism that is based on the Lightweight Directory Access Protocol (LDAP). Starting with DS8000 Release 9.1 code, a simpler, native LDAP authentication method is supported along with the former implementation that relies on IBM Copy Services Manager (CSM) acting as a proxy between the DS8000 and external LDAP servers. Note that examples and operations shown in this Redpaper refer to the DS8000 R9.1 SP1, code release bundle 89.11.33.0.
