Hi.
I am currently running a pair of lvs directors in LVS-NAT mode, handling
about 10MBit loads. the real servers are NT boxes, that run the dinamic part
of my site (asp). the rest of the site (static content) is being served by 2
tux/apache servers, protected by heartbeat. the combined incoming traffic to
these servers is about 10MBit, but the outgoing is approaching 100MBit, so i
am about to add another tux/apache server to share the load, and here i will
have to drop the heartbeat and setup LVS-DR to these 3 servers.
in the lvs howto there is an assumption that a linux box on 100MBit network
is actually a 8000 pps box - it says this was done in the times of 2.2
kernels. is this assumption still valid ? summed up, my site currently
approaching 14000 pps all together in peaks - routing all this traffic
through a single director in this case could be problematic . the director
is 2 cpu 1GHZ IBM x330 . is anybody running such setup ? any suggestions ?
i currently have 100MBit switched network on cisco 2900 which is connected
to the main switch of the provider with several 100mbit ports configured as
a port-group (etherchannel), so the outbound bandwidth capacity should be
sufficient for the perpose . it's the pps that troubles me after reading the
howto. i would really like to stay with 100Mbit nerwork, since none of the
servers (nor the switch) have Gig interfaces.
At the time i have tested this director to do lvs-nat to all the servers,
back then the overall traffic of the site was about 30MBit. Of course, i
will run my own tests, and post them to the list, but if someone has already
done these, it would really help.
