perfSONAR User Q&A and Other Discussion

[Chris Dagdigian <>]

In a high performance computing context the current Intel haswell stuff 
is driving 40Gbps interfaces so servers that can handle 10Gbps should 
not be particularly hard to find.

For commercal/biotech clients I've recently helped purchase HP branded 
server hardware for both perfSONAR use as well as to drive our data 
transfer nodes running Globus Connect server. If you want to drop me a 
line off-list I can share general info about the hardware we used on 
that project.

Note that we did not get guarantees from the vendor though. We have been 
able to drive both the perfSONAR and the data xfer nodes close to what 
we'd expect to be their real world limits before heroic host and network 
tuning is done. Our environment has firewalls and amazon direct connect 
in the mix so there are a lot of moving parts that affect real world 
throughput.

Happy to share info off list.  I also think that the perfsonar/ESNET/I2 
people are somewhat constrained in being able to mention brands and 
vendors -- they can't really be seen to be picking favorites etc.

Regards,
Chris
