TAILIEUCHUNG - An ITIL-Based Approach to Building Effective Storage Capacity Management in Support of ILM

Understanding the current state of your storage infrastructure—what capacity you have, where it is located, who is using it, who is paying for it, how efficiently it is being used, and how well it is meeting SLAs—is fundamental to intelligently planning, provisioning, and managing storage. Buying and deploying storage as it is often done on a per-project basis— based on loose estimates of immediate and future required capacity, application requirements, and response times—typically results in over-purchasing of hardware and poor allocation of resources. These are costlymistakes, with less than desired operational efficiencies, including the risk of outages when storage is simply unavailable | Written and Provided by Global Knowledge EMC2 where information lives Expert Reference Series ofWhite Papers An ITIL-Based Approach to Building Effective Storage Capacity Management in Support of ILM 1-800-COURSES Introduction .2 The Solution An ITIL-based Storage Model Considerations . . 3 Implementing Capacity Management Getting Started . . 3 Assessment and Rebalancing your asset Implementing an improved asset portfolio .5 Monitoring your storage environment .6 Summary and Next About the Introduction Understanding the current state of your storage infrastructure what capacity you have where it is located who is using it who is paying for it how efficiently it is being used and how well it is meeting SLAs is fundamental to intelligently planning provisioning and managing storage. Buying and deploying storage as it is often done on a per-project basis based on loose estimates of immediate and future required capacity application requirements and response times typically results in over-purchasing of hardware and poor allocation of resources. These are costly mistakes with less than desired operational efficiencies including the riskof outages when storage is simply unavailable. However most organizations do not have the tools and processes in place to effectively gather and track the information necessary to make an informed decision about storage provisioning. Traditional manual methods are highly resource- and labor-intensive extremely inefficient and costly and deliver only a subset of information. As a result decisions to purchase or configure more storage are most often based on perceived instead of real needs and expectations and estimated instead of actual consumption and performance. The Solution An ITIL-based Approach Capacity management is a sub-process within the Information Technology Infrastructure Library ITIL framework that allows companies to quickly easily efficiently and .
