slighty OT: new hardware for a mapserver application

[Dylan Beaudette]

Thanks for the tips Ed,

There should be about 100Gb of imagery in geotiff format, 5 to 10 Gb of vector 
data stored in shapefiles, and about another 5 to 10 Gb of tabular data 
stored in MySQL.

I am not expecting a huge number of hits per day, but right now it is hard to 
say... perhaps 10 to 100 requests per day?

We are considering a dual processor xeon system with SCSI disks, as this 
closely resembles our test machine.

Thanks again, 

Dylan
