Re: [Ntop-misc] Mac Pro and n2disk

Hi
 
Thanks Luca for your answer, I think I'll go on the direction of a rack mounted server.
So if I want to create a wire-rate recording server with n2disk for 2X10 Gbps, do you think one raid controller would be enough, or should I use 2 seperate controllers?
Is there a risk of an I/O bottleneck?
 
Regards,
Tory

Hi Tory
N2disk works on OSX but for 10g you need to use Linux. We know people who have tried thunderbolt and the outcome is that the performance is suboptimal (I have seen a report during the sharkfest conference) so I think OSX is not yet a viable alternative to Linux both in performance and price

Hi guys,
 
I'm trying to assemble a multi-gigabit packet capture machine that is both portable and able to capture traffic of up to 2X10 Gbps.
The requirement of portability (small and light) is essential and so the natural choice is the mac pro with it's high performance and small size, using a PCIe cage with thunderbolt and intel's 10 Gbps NIC.
Also - wanting to be able to capture highspeed capture I'm aiming at using pf_ring, dna and n2disk. To do that I'll need to run ubuntu/centos natively on the Mac pro.
 
Does anyone have any experience with that kind of setup or with running pf_ring on an apple machine?
To the ntop team- do you have experience with using pf_ring, dna on a NIC through a thunderbolt interface? and- has pf_ring been tested on apple devices?
Is that theortically possible?
 
Thanks in advance,
Tory
