The introduction of SATA-based arrays may actually have been a catalyst rather than an enabler for multi-tier storage, heightening user awareness of the many online data storage options for their applications, each with its own availability and performance characteristics and associated cost.

  Learn how multiple tiers of storage hardware simply add to the number of options available to users, how any type of software-based virtual volume can be created from any type of storage device or LUN presented by disk arrays - and get tiered storage best practices recommendations for use and detailed technical guidelines.

  Read this Yellow Book to learn how dynamic storage tiering can help your organization with:

• File relocation
• Efficient backup for inactive files
• Storage reclamation
• Managing storage for databases
• Exploiting MAID-based storage
