Hi!
Is anyone running active-active(-active...) LVS setups? Is
it saru or something else?
saru was a proof of principle piece of code by Horms a few
years ago. It was done for one kernel and has not been
maintained through the subsequent kernels.
It's seems it should be possible to do it without saru by
having multipath route-capable router upstream dividing
the traffic between all the directors. If you can manage
the routes with OSPF, it should be possible to have
active-active directors using more common protocols and
software with the added benefit of each director only
receiving the packets it ends up handling.
Any thoughts, comments, experiences with anything like this?
few of us have access to routers to try such experiments. So
it's possible this would work, but few people would be able
to implement it.
I've been to talks where people manually redirected traffic
from busy servers to less busy servers on the other side of
the continent in this way, as load changed during the day,
so presumably some people are doing this all the time
already.
How would you tell the routers to divide the traffic?
