Value
The Storage Service Catalogue Model:• Provides a central source of information• Ensures an accurate, consistent picture of all
storage services, their details and status• Contains user-facing view of storage services in
use, how they are intended to be used, business processes they enable and quality of service to be expected.
• Maps the reference architecture to the services it enables

Challenges and Pitfalls
• Maintaining accurate Storage Service Catalogue Model as part of a Service Portfolio
• Culture of the organization needs to accept that the Catalogue and Portfolio are essential sources of information that everyone within the organization needs to use and help maintain
• Is not a CMDB, but can be complementary• Get your metrics right• Have a reference architecture
