[TriLUG] 536 GB of allocated virtual memory

[Jason Tower]

we have a client who insists that their T-1 connection delivers 1.5 Gb/s and 
not 1.5 Mb/s.  they'd probably like to purchase one of these servers so they 
can utilize all of their bandwidth, can you send me the exact model number? 
  thanks,

jason
