[SDBUG] OpenBSD on Dell issues ?

[Michael J McCafferty]

All,
	I am am on the verge of pulling the trigger on a hardware buy for some
new firewalls to run OpenBSD 4.1, PF, CARP, pfsync. As we have discussed
at the SDBUG meetings in the past, I have issues with interrupts on the
CPU when the packets per second get high.
	I am replacing the current hardware within 2 weeks. The current system
was installed when it was expected to handle 10 to 20 Mbps peak and
about 2 to 5Mbps average. I now need a setup that can handle 20 to
50Mbps average now, with peaks to 200Mbps and future growth to several
hundred Mbps peak at which time I assume that unless there is some major
advance in servers/PCs/x86_64 architecture, I will have to go to ASIC
based devices (ie: Netscreens, etc) and not be able to use my beloved
PF. But I digress... what I really need to know is:

	Is anyone currently running OpenBSD on Dell 1950s with the SAS 5/i
SATA/SAS controller ? Any problems ? The Dell dude I spoke to said there
may be issues with FreeBSD and the disk controller.. but that he only
heard that some place and has no details on that. Or shall I use the
PERC 5/i controller instead ?
	Is anyone using Intel PCIe Gig NICs ? I have been using the dual-port
Intel GigE NICs for PCI/PCI-X, but not PCIe. Any known issues ?
	The system comes with Dual Embedded Broadcom NetXtreme II 5708 Gigabit
interfaces. Will these be usable under OpenBSD 4.1 ? 

	A beer for useful input ! Say, isn't there a meeting tonight ?

Thank you !
Mike
