Parallel Sysplex Cluster Technology

IBM Systems Director Active Energy Manager

IBM Systems Director Active Energy Manager(AEM) is a building block which enables customers to manage actual power consumption and resulting thermal loads IBM serv- ers place in the data center. The z10 EC provides support for IBM Systems Director Active Energy Manager (AEM) for Linux on System z for a single view of actual energy usage across multiple heterogeneous IBM platforms within the infrastructure. AEM for Linux on System z will allow tracking of trends for both the z10 EC as well as multiple server platforms. With this trend analysis, a data center administrator will have the data to help properly estimate power inputs and more accurately plan data center con- solidation or modifi cation projects.

On System z10, the HMC will now provide support for the Active Energy Manager (AEM) which will display power consumption/air input temperature as well as exhaust temperature. AEM will also provide some limited status confi guration information which might assist in explaining changes to the power consumption. AEM is exclusive to System z10.

IBM System z servers stand alone against competition and have stood the test of time with our business resiliency solutions. Our coupling solutions with Parallel Sysplex technology allow for greater scalability and availability.

Parallel Sysplex clustering is designed to bring the power of parallel processing to business-critical System z10, System z9, z990 or z890 applications. A Parallel Sysplex cluster consists of up to 32 z/OS images coupled to one or more Coupling Facilities (CFs or ICFs) using high-speed specialized links for communication. The Coupling Facili- ties, at the heart of the Parallel Sysplex cluster, enable high speed, read/ write data sharing and resource sharing among all the z/OS images in a cluster. All images are also connected to a Sysplex Timer® or by implementing the Server Time Protocol (STP), so that all events can be prop- erly sequenced in time.

Parallel Sysplex Resource Sharing enables multiple system resources to be managed as a single logical resource shared among all of the images. Some examples of resource sharing include JES2 Checkpoint, GRS “star,” and Enhanced Catalog Sharing; all of which provide sim- plifi ed systems management, increased performance and/ or scalability.

Although there is signifi cant value in a single footprint and multi-footprint environment with resource sharing, those customers looking for high availability must move on to

a database data sharing confi guration. With the Paral- lel Sysplex environment, combined with the Workload Manager and CICS TS, DB2 or IMS, incoming work can
