11、inition and Critical FunctionsThere are over 20 vendors that are shipping products in the storage resource management market.HurwitzGroup defines the SRM market as:Storage resource management:Software that manages storage resources from a capacity,utilization,policy,and event management perspective.

12、This includes bill-back,monitoring,reporting,and analytic capabilities thatallow drill down for performance and availability.For the analysis,Hurwitz Group has defined the 10 critical functional areas for a complete storage resourcemanagement solution.There is no single vendor that has all of the of

13、ferings today.However,future productroadmaps and integration paths for most vendors will increasingly offer the 10 functional areas through a singleinterface.These 10 areas are:1.Asset management.The ability to manage,track,and maintain storage hardware information.2.Charge back.Enables customer bil
