Hi Glenn,

CMS are re-evaluating their computing model, both Dave Newbold and neil 
geddes are involved in the process but the spreadsheet for resource 
modelling is still at an early stage and so these numbers are a little 
more finger in the air than I would like but are the best that I can do 
at the moment. The only obvious thing is that we are short of disk and 
another ~250TB would be sufficient to enable to have both the RECO and 
AOD for the first year on disk, which would be of great benefit for UK 
physicists (and those Physics groups they support). Also we are 
effectively loosing 200TB because of the import and export buffers. This 
means that I will be asking for more disk than is available which is 
something that we will need to discuss and come to some arrangement on 
in the meeting (or before hand). The Tier 2 numbers are what I actually 
expect to be on the ground anyway earmarked for CMS.

So T2 first (as they are easier)

	July 	Aug	September
CPU 	1000	1100	1100
Disk 	248	268	268

T1 (harder)

	July	Aug	September	
CPU	850	1250	1250
Disk	850	1100	1100
Tape	700	800	900

The increases in CPU and Tape are very much finger in the air, however 
the UK does appear to have capacity to cover these but not the disk 
(which is the one part that isn't).

I also wouldn't expect these numbers to change too much in Q4 (infact 
they are really the numbers that I would hope for in Q4 but have put a 
ramp up into to cover anything like CSA08 - phase 2) but haven't put 
these numbers in because I will have updated numbers from the revision 
of the computing model and so will be able to make a more informed bid 
in a quarters time.

All the best,
david
