The default configuration for using Linux Director would be no load balancing at all and one machine on standby with Heartbeat. We could do the same with the squids, but it makes more sense to use both machine's ram.
I'm not sure I'm following you here. If we have 2 Linux Directors, one on standby, but they aren't doing load balancing, then what are they for? I thought the director would be in charge of (iptables style) load balancing the squids?
for cpu, but for future memory expansion. I think Raid isn't necessary for the squid if the logging is done to a separate disk.
*nod* But RAID could be used in mirroring mode to increase reliability, presumably...
I'm listening to your thought that maybe going with a 64 bit CPU might make more sense just from the point of view of more RAM potential in the future. It's just very hard today to predict whether that's the right path to take or not.
One can only assume that RAM will be a lot cheaper in the future, and it sure would be nice to spend $1600 per machine to upgrade to 16Gb. :-)
