  2. 2. A Blueprint for Lowering Capital and Operational Costs for Storage Infrastructure Unprecedented data growth, new application demands, regulatory requirements for data archival and greater business continuity needs are straining IT budgets and exposing inefficiencies in conventional storage architectures. One of the most pressing issues facing organizations today is the need to reduce storage costs. Simultaneously, single vendor management tools and isolated pools of storage fragment the infrastructure, making it difficult to share resources, improve operational efficiency and migrate online data. By implementing a virtualized tiered storage architecture, an IT organization can dramatically improve storage capacities and lower capital and operational expenses. Virtualized tiered storage better aligns data on storage systems by allowing you to efficiently match storage attributes with the service level needs of individual business applications. legislation, are setting mandatory guidelines The Cost and Complexity for data protection and data retention, with of Storage financial and legal penalties for noncompli- Storage environments large and small face ance. Like business resilience measures, increasingly sophisticated demands from ensuring your organization is in compliance business applications and requests to with government regulations implies maintain data online for longer periods of time. increased capacity and complexity in the As a result, total capacity being managed by storage environment. Meeting the need for IT storage administrators has exploded and enhanced data protection, greater regulatory the complexity of the storage infrastructure compliance and escalating demand for has grown enormously. These factors are application storage capacity inevitably drives raising the total cost of the storage ownership up the cost of storage. and significantly affecting the IT budget.

Eliminating barriers to sharing, storage recovery and improving capacity utilization rates can deliver sustainable long term savings by allowing future purchase of storage assets to be deferred. Software Costs With heterogeneous configurations the norm in enterprise data centers, managing storage requires the use of many software tools from different vendors. These tools frequently do not communicate well with each other, complicating the process of provisioning, optimizing, moving and protecting data and increasing training costs. labor Costs Labor expenses represent as much as 40 percent of the total cost of storage ownership. The best meaningful way to NAS = network attached storage lower storage labor costs is to reduce the CAS = content addressable storage VTL = virtual tape library operational management complexity of the storage environment.
