Hi,
I'm currently in the process of selecting hardware for a FreeBSD
system having the main task of collecting network statistics via MRTG
or RRDtool. In addition the machine in question should be used to
collect netflow statistics plus providing a web-interface for
displaying them.
To give you an impression about the workload to be expected: Currently
the system is a dual Xeon machine with 3GHz-CPUs reaching work loads
(top) of 7 to 9. Disk-IO btw is not the problem.
For the new system I thought about a 4-CPU machine, 4GB RAM - with
either 32- or 64-bit architecture.
AMD has the market cornered on 4-way and up boxes. Have you thought
about a 2-way box with dual core CPUs?
Here are my questions:
o) Should I stick with a 32-bit architecture (i386) or go for any of
the 64-architectures?
Do you need more then 4GB of RAM, if so then your only option is 64-bit.
o) Is FreeBSD 6.1 considered equally stable under the i386
architecture as under any of the 64bit architectures?
Sure, and you can still run i386 FreeBSD on a 64-bit chip.
o) Are SMP-systems with 4 CPUs supported in i386?
Yes.
o) Are SMP-systems with 4 CPU supported in any of the 64-bit
architectures?
Yes.
o) Anything else to consider in this context?
Code compiling is very fast on AMDs chip thanks to HyperTransport and
the on-die memory controller, if your task can take advantage of this
AMD is your best bet.
