Consolidating storage using a SAN or other technique can save an enterprise considerable amounts of money, and improve performance as well. Generally speaking, you can perform consolidation in one of three ways: move applications from multiple independent servers to a server cluster or to a single storage server; attach heterogenous servers to a storage device or using a SAN; and consolidate data on a common file system.
In a white paper on storage consolidation, Sun Microsystems Inc. offers a checklist to help determine if consolidation might benefit your business.
Among the questions you need to answer are:
- Is your storage growth difficult to predict and/or manage?
- Does your data need to be updated more often that it is currently?
- Are IT dependencies not fully understood, leading to incorrect management disciplines being applied?
- Is your business experiencing problems handling incoming Web traffic efficiently?
- Is your business experiencing problems scaling quickly and non-disruptively to meet growing demands?
- Are planned or unplanned service or maintenance outages disrupting production?
The complete list is available in the Sun white paper titled "Storage Consolidation: How to Reduce IT Costs and Complexity" on the Sun Web site at
