Using tmpfs is pretty much your only option.

Is that possible? This is definitely possible, though I don't think it's necessary. I have machines handling 1500 reporting nodes without problems, writing the rrds to a tmpfs. The downside of setting up ganglia with head nodes is that you have to set up some way to make the rrds available to a central web server. Several ways to do that too, but they introduce their own headaches. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
