  2. Storage Growth & Management • Disk storage system TB shipments are increasing almost 80% per year. • Storage managers must improve efficiency more than 60% per year.

  3. Skills shortage is increasing • Unfilled IT positions are growing more than 5% per year. • More than 1.8 million IT positions will be unfilled in 2003. • The networked world makes job-switching easier. • Storage management positions taking more than 4 months to fill. • DBA positions taking 12 months to fill.

  4. Storage Related Business Issues: Storage Management - the REAL cost of Storage … the cost of managing data per megabyte can range from five to ten times the cost of the physical storage medium. John Webster - Illuminata Inc. Storage Analyst and IT adviser For every dollar that a company spends on storage, it can expect to spend ten times that sum in management costs. “The Holy Grail of Data Storage Management” by Jon Toigo Prentice Hall, 2000 As storage hardware becomes an increasingly smaller portion of the total cost of storage infrastructure ownership, the value for suppliers and the largest expense for the customer moves from hardware to the management of storage. Storage Infusion by Fred Moore President Horison Information Strategies

  9. How can I at least minimize my “Planned” downtime? Storage Related Business Issues:The Cost of Downtime • The Effects of: • Adding new Storage • Upgrading Existing Storage • Servicing • Replacing • New Technology • Change is a constant in the Open Systems World

  11. Storage Area Network The SAN Today Managing Data Growth • Addressed via Storage Pooling • Requires Less Storage Assets • Provides Greater Utilization • Consolidation of Spares

  12. Storage Administration and Management Storage Area Network The SAN TodayCost of Storage Management (People & Administration) • Today’s SAN solutions Partially address this issue • Storage is centralized • People Resources are Centralized • Homogeneous Solutions - One Vendors Storage, Server, or Software • What happened to OPEN SANs?

  15. Storage Management Goal: Server-independent management, administration and access to a heterogeneous, shared storage environment: • Enable expansive sharing of storage devices • Enable logical consolidation of storage management actions • Free application servers from storage management overhead • Accommodate growth and technology changes • Reduce costs of managing and administering complex storage environments
