I'm not sure, since I'm not sure about the precise meaning of a grid, it seems to be a term used for a lot of different things. However I am running a 70 node webfarm and a 50+ node database farm behind a couple of LVS based load-balancers with keepalived as management/monitor/checking software. I will say very nice things about it, most importantly it has proven to be a very flexible load-balancer setup which configured correctly is able to sustain a massive amount of load. The load-balancers are running on commodity dell hardware. Right now it's load-balancing our >18M pageviews/day website without a hitch. WRT databases, we load-balance a number of mysql-replication setups through it and that is working very good for us. However that is also caused by the fact that connection initiation for mysql is extremely fast and low on resources. Oracle is far slower and resource-hungry wrt to setting up a connection. If you have any questions I'll be happy to answer. Ramon -- gentoo-cluster@gentoo.org mailing list
