Storage Management Via Virtualization RB Hooks, III Storage Strategist Storage Technology Corporation
Storage Growth & Management • Disk storage system TB shipments are increasing almost 80% per year. • Storage managers must improve efficiency more than 60% per year.
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.
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

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
