Product Overview

Direction for z/OS employs a Windows-based architecture centered around a GUI, a modeling engine, and a proprietary data repository. The GUI serves as the primary interface for user interaction, enabling configuration of the DASD environment, initiation of simulations, and visualization of results. The modeling engine utilizes mathematical models and simulation techniques to predict performance metrics based on the defined configuration and workload parameters.

The data repository stores configuration data, simulation results, and other relevant information. Key architectural components: * **GUI:** The graphical user interface provides a user-friendly environment for interacting with the tool. * **Modeling Engine:** The core component responsible for simulating DASD performance based on defined parameters.

* **Data Repository:** A proprietary storage mechanism for configuration data and simulation results. Communication between components occurs through internal processes. Direction for z/OS requires network connectivity for accessing data sources and for licensing purposes.

While competing products may offer alternative architectures or integration capabilities, Direction for z/OS provides a comprehensive and self-contained solution for DASD performance modeling.

Frequently Asked Questions

What is Direction for z/OS and what does it do?

Direction for z/OS is a Windows-based tool used for DASD performance modeling. It helps predict the impact of DASD configuration changes or upgrades on system performance.

How does Direction for z/OS predict performance?

Direction for z/OS analyzes I/O patterns, device utilization, and workload characteristics to simulate performance under different DASD configurations. It uses mathematical models and simulation techniques to predict response times, throughput, and other key performance indicators.

What types of DASD configurations can be modeled?

Direction for z/OS can be used to model various DASD configurations, including different storage device types (e.g., SSD, HDD), RAID levels, and caching strategies. It allows users to evaluate the performance impact of these changes before implementing them in a production environment.

How is the DASD environment defined in Direction for z/OS?

Direction for z/OS uses configuration files to define the DASD environment, including device characteristics, connectivity, and workload parameters. These files are typically created or modified using the GUI.
