Depends on what sort of machine you use for your front end, and what the software is. Are these servers for IMAP/POP or are these postfix/exim etc? > I think I would need the necessary Infiniband cards in each server > along with an Infiniband switch.

Simplest architecture is a small IB switch, IB HCA's in each node, an IB stack (OFED) in each node, a subnet manager (OpenSM) daemon, IB cables, and then Gluster built against your stack. Make sure your time daemon is up, running, and correct between the nodes. Give serious consideration to really fast disk in each node (fast IOP, so SSD, in RAID10). Once you have that, you are ready to build your volumes (probably replicated distributed, so 4 way at least). Do beware that there are some gotchas in configurating MTA/MUA software for Gluster. Its doable, but such software often abhors shared storage of any sort. You need to make sure that you turn down some of the caching. > > Thanks in advance. > > Bryan McGuire Senior Network Engineer NewNet 66 > > 918.231.8063 bmcguire at newnet66.org Regards, Joe -- Joseph Landman, Ph.D Founder and CEO Scalable Informatics, Inc. email: landman at scalableinformatics.com web : http://scalableinformatics.com http://scalableinformatics.com/sicluster phone: +1 734 786 8423 x121 fax : +1 866 888 3112 cell : +1 734 612 4615
