storage architecture vision

yesterday I presented my storage architecture vision
for the bank. It was well perceived, and here's the recipe to write such a document:
- start by finding the right documents, and who wrote them (owners). Initial document inputs are the global strategy of the company, IT principles, and all the architecture documents you would find
- Write a first part, relating to how these inputs apply to storage
- List all the storage building blocks and develop how you would use them
- Define a set of rules for these building blocks
- Define the services you provide to your "customers" (in this case, customers=internal groups)
- draw a nice big diagram
- Present everything in front of the stakeholders

et voilà
