what is the expected growth in UK storage area networking?

You might have to paste this entire URL together. It's an abstract of
a report you can buy for US$495 by the Aberdeen Group (with whom I
have no connection) entitled:

Worldwide Storage Management Spending
Forecast and Analysis 2001-2005 

http://researchcentre.zdnet.co.uk/data/detail?id=1016471620_973&type=RES&x=1506122404

In the abstract (that's free) they do point out that the "storage
management market will grow at a compound annual growth rate (CAGR) of
27.7% to nearly $21 billion by 2005."
