  3. 3. Managing and understanding mainframe A Holistic View of storage performance is critical. Yet many Disk subsystem Activity RMF MAGIC organizations have discovered that their RMF Magic processes RMF data originating existing performance management tools from one or more z/OS servers to extract are no match against an increasingly and consolidate configuration and I/O complex storage environment. As a result, load data by physical disk subsystem. they cannot generate the types of metrics Organizations receive a disk-centric view of needed to assess, let alone manage, disk subsystem I/O load and performance, mainframe storage performance. regardless of the number of servers or Parallel Sysplexes to which they are RMF Magic is a software tool that provides attached. As a result, they gain detailed visibility into storage, replication, and insight into subsystem performance and FICON performance. It processes Common areas that require more focus. Message Format (CMF) or Resource Measurement Facility (RMF) data to Simplified Use on z/OS or PCs generate the metrics organizations need To provide greater flexibility, RMF Magic can to understand and optimize workload run as a batch job on z/OS or on a Windows performance, even inside disk subsystems. PC. In addition, organizations can use RMF Magic also provides deep insight into RMF Magic to run interactive data analysis System z storage performance. on their PCs. Using dashboard graphs, Because it requires no programming, RMF they can easily see the difference between Magic enables organizations to focus on recurring I/O load peaks and performance analysis rather than coding. In addition, anomalies—without having to write technical it creates new information from existing database queries. data and generates graphical views of performance data. Organizations can use RMF Magic to: • Run disk subsystem health checks for early warnings about I/O performance degradation, streamlining diagnosis and root-cause analysis • Analyze performance from data set to disk subsystem over a period of time in order to optimize workload distribution across resources • Determine whether tuning I/O load distribution will yield additional capacity • Evaluate FICON health
  4. 4. Understanding disk subsystem performance Major Vendor support becomes more complex every year Disk Magic supports disk subsystems DIsK MAGIC as organizations must consider how from all major storage vendors, whether technologies such as high-capacity disks, those subsystems are attached to open high-capacity logical volumes, RAID systems servers, System z, System i, or schemes, Fibre Channels, synchronous and a combination thereof. It also supports asynchronous copy services solutions, and Transaction Processing Facility (TPF). cache size options will affect service levels for their various workloads. Automated Input of I/O Workload Data Disk Magic features automated procedures Disk Magic is a powerful, versatile disk to enter I/O workload data, using reports subsystem performance analysis and created by standard products such as iostat planning tool that can help IT organizations for UNIX and Linux, Perfmon for Windows, understand how performance for specific and Performance Tools for System i. (For workloads will change under various growth System z, IntelliMagic’s RMF Magic can and/or hardware configuration scenarios. create automated input files based on RMF It displays current and expected response or CMF data.) times, component utilization levels, and throughput limits for I/O loads and server Easy Access to Data configurations. As a result, organizations Disk Magic runs on a Windows PC, and no can use Disk Magic to confidently select the connection to the actual disk subsystem most cost-effective configuration options. is needed. Organizations can view results With Disk Magic, organizations can: via the graphical user interface and in text reports or charts. • Predict how moving workloads to different tiers of storage will affect response times Accurate scenario Modeling and I/O loads Disk Magic can create a mathematical • Run disk subsystem health checks to representation of the current storage understand and track utilization levels environment. Using this as a baseline, organizations can easily model the effects • Assess the result of consolidating of changes, including increased I/O load, multiple disk subsystems replacement of ESCON with FICON, the • Predict the performance benefit gained movement of workloads to another disk from adding cache, channels, or new subsystem technology, and the performance technologies of RAID 10 versus RAID 5. • Assess whether energy-efficient, high-capacity drives will support required Storage Virtualization Planning service levels Organizations can use Disk Magic to plan and monitor IBM SAN Volume Controller • Monitor and model z/OS storage configurations, including back-end disk performance to identify poorly subsystems. By using Disk Magic’s standard performing volumes I/O load profiles or entering current workload measurements, they can predict what will happen if a SAN Volume Controller is added to the configuration.
  5. 5. Tape remains an important medium for Efficient SMF Data Consolidation storing large amounts of information. from All LPARs BATCH MAGIC Recent innovations in virtualization have Batch Magic provides a consolidated view made tape storage easier and more on all tape-related activity, regardless of economical to use, enabling IT organizations the number of LPARs or Parallel Sysplexes to maintain a secondary copy on a remote to which the tape libraries are attached. site without having to transport tapes. As a It analyzes the tape workload at both the result, organizations must ensure that tape application level and the hardware level. hardware investments are well planned and intelligently mapped. Simplified Use on Both z/OS and Windows Platforms A powerful application designed for z/OS Organizations can run Batch Magic as a tape and batch window tuning and capacity batch job on z/OS or interactively on a planning, Batch Magic can help organizations Windows PC. In addition, organizations can optimize the use of tape libraries, monitor view the output as printed reports, or use the load on virtual tape systems, and better the Batch Magic Windows application for understand tape workloads. interactive reporting and graphing on the PC. Batch Magic efficiently consolidates information about tape usage across Flexible Workload Definitions Logical Partitions (LPARs), even from several Organizations can create their own workload Parallel Sysplexes, providing a comprehensive grouping criteria for Batch Magic to report overview of all tape activity. It can analyze on. They can see the scratch and specific weeks of System Management Facility (SMF) mount counts and rates, the read and write records to show tape workload behavior and megabytes, volume statistics, and many patterns over time. other metrics for each workload. Sample workload grouping definitions distinguish Organizations can use Batch Magic to: the major tape applications based on data set names, providing useful reports. • Report on overall tape workload performance Intuitive Graph and Table • Tune the tape and batch window by Reporting Options optimizing application scheduling Batch Magic reports are in a tabular format • Easily monitor tape usage over time and on the mainframe, and are created directly in analyze tape performance trends Excel by the Windows version of Batch Magic.
