Hi Nicolas.

Here's what we are currently using:

Service: RRD MA
PC type: HP Proliant DL360 G3
Processor: 1x XEON, 3200 MHz, 8KB L1 Cache, 512KB L2 Cache, 1024KB L3 Cache
Memory: 2x 1024 MB 266 MHz DIMM
Number of Interfaces exported: 330
Appreciation: depends on how heavily used; we had some performance issues 
with all the CNM accesses. The system could hardly be used for anything else 
anymore. Seems better now, maybe the DFN folks have optimized their CNM 
access.
OS: Linux 2.6.17-web100 (Debian)

Chris
