hello there
we are planning a medium lan party with about 200 - 300 clients.
it's a
normal gamer lan party but there will be a lot of traffic.
we will habe about 6 subnets (like 10.5.0.0/24, 10.6.0.0/24, and so
on)
that we have to route under each other. if we get a good sponsor we
may
habe some layer 3 cisco swiches that can do wirespeed routing.
but i dont think so... i may have to get some 3 GHz Intel P4 Boxes
(About 1 GB Memory) and do the VLAN Routing on these openbsd boxes.
will i get about 1GBit/s throughput with such a box?
is it better to use a gigabit ethernet card for each subnet or
should i
get the vlans on one intel card?
is it better to route all vlans on one box or should i split up the
routing on about 3 boxes?
I just deployed a similar setup using a pair of OpenBSD/CARP servers
on inexpensive servers and a cluster of Cisco 2950s. Each server is
an Iron Systems A320R with a 2.0 GHz Celeron, 256MB memory, 64bit/
66MHz PCI-X slot, dual onboard Intel 1000BaseT, and onboard CF-to-IDE
adapter in place of the original SATA drive. A 64bit SysKonnect
1000BaseT in the PCI slot and handles pfsync traffic.
The internal em interfaces are trunked on Cisco 1000BaseT GBICs.
Each router handles 10 internal VLANs on carp interfaces. My iperf
tests maxed out at ~500Mbps; a faster processor and more bus would
likely yield much higher throughput. Still not bad for around $700
per server.
