The main goals are redundancy and increased load capacity. RFC 2391 "Load Sharing using IP Network Address Translation (LSNAT)" has a good description of the idea. I've got about 150G of information (and growing rapidly) to publish that will live on a raid-5, which we are planning to share to the cluster over NFS on a 100base lan. ------ 100baseT/NFS | raid |--------------------------- ------ | | | | | | -- -- -- |w1| |w2| |w3| -- -- -- | | | | | | ------------------------------- | | -------- | load.b | -------- | | Inet We would initially be using it for balancing http sessions among web servers, but may want to use it for other protocols as well. I thought I read about fbsd being able to do this through natd, but when I looked at the man page for it, I didn't see anything like that. I read about Engelschall's mod_rproxy, but was hoping to find something that operated at the session level, so it wouldn't be protocol specific. Any insights/links/suggestions would be greatly appreciated! Thanks!
