I wasn't able to find this information in the handbook or on the freebsd.org website, so would appreciate any answers or pointers to documents I missed. The Project: I need to develop a high speed network sniffer in order to debug an application running on Windows NT. The sniffer needs to capture traffic at 200-300Mbps (25MBps-38MBps) and write packets (or at least headers) to disk, limited only by the amount of disk. Our NT application runs on a dual PIII 600, using sysKonnect or Alteon Gigabit Ethernet cards and writes upwards of 200Mbps to disk using software RAID 0; I assume I would need a similar configuration for the FreeBSD box. My questions include: - what is the maximum filesize (we would exceed 2GB in less than 2 minutes)? - what is the state of SMP support (the SMP project page is out of date)? - are there any vinum limitations that would prevent me from capturing ~100GB worth of traffic? - any other limits? Any information or comments on the viability of the project would be very helpful.
