Subject: results from our meeting
Number of backend switches assumed to be 4. 
Each backend switch has about 50 ports and costs about  $50,000 

Each switch has another 18 smaller switches attached to it each switch will cost about 
$2000 giving a total of $36000 

The number of PCs attached to each of the 4 switches is in total 
414 dual processor units cost per unit is $3000 making a total of  $1,242,000 

Total cost for each of the 4 subsystems based around the 4 switches = $1,330, 000 

Total cost of 4 switches and associated PCs = $5.3M 

Observations... 

Networking has small effect on total cost. Could be changed to all GE? Can change from 4 to 8 central switches or more without impact. 

Go through some scenarios for partitioning and also control of remote farms. 

Explore concept of standard farm rack for level 2 and Event farms
