Intelligent resource director

Intelligent Resource Director (IRD), a feature of the IBM eServer zSeries™ processors and the z/OS™ operating system, manages multiple heterogeneous workloads with various business priorities toward achieving their goals. It establishes a more synergistic relationship with the Workload Manager (WLM) component of z/OS and the zSeries hardware, and augments the adjustments that WLM makes to local sysplex members by managing the set of logical partitions on a particular central processing complex (CPC) that are part of the same sysplex, known as a logically partitioned (LPAR) cluster. This paper describes the three primary areas that IRD manages: LPAR CPU management, channel subsystem priority queueing (CSSPQ), and dynamic channel path management (DCM).

IBM totalstorage productivity center for replication for z/OS

Designing and implementing a business resilience (or disaster recovery) plan is a complex procedure for customers, and the impact of implementing an incorrect or incomplete plan can be significant. For some customers, being able to recover their data center functionality in a short period of time may be of the utmost importance; for others, recovering in a short period of time may be worthless if the data with which their database is restored is hours or days old. Also of importance is the impact to business-critical applications when copies of data are being made. This paper presents the IBM TotalStorage™ Productivity Center for Replication (TPC-R), a tool designed to help customers implement cost-effective data replication solutions for continuous availability and disaster recovery. We give an overview of TPC-R, describe recent enhancements to TPC-R that are available on all supported platforms (as well as those that are unique to the z/OS™ platform) and discuss the ways in which customers can exploit TPC-R to implement business resilience solutions, with a focus on the various trade-offs customers must consider when choosing between different storage replication technologies.
