With 64Bit it should many ram avaible. Greeting In theory, max RAM would be 18446744073709551616 bits (2^64) I know it is possible to configure a system with 64 cores (4 x 16-core cpus). However, I haven't seen definitive tests on scaling that far. Last I saw, somewhere in the 6 to 8 core range, you really hit the point of diminishing returns. If you are doing lots of jails, I would suggest splitting up 'sets' of jails and limiting them to run on a group of specific cores. In the above configuration, you could have 8 groups of 8 cpu-cores, each handling a specific set of jails.

Putting your faith in one big server can be a problem if the box fails, especially hardware failure. Keeping a spare server in a rack that can be switched in to service quickly can save you if one dies. Time (waiting for parts), most failures are hardware if your running FreeBSD. Even most Linux boxes. There are 2 approaches, and applying both together is what I favor. Scale up (vertical) is a horsepower per box kind of thing. Scale out (horizontal) adds more of the same kind of box(es) in parallel. The resulting redundancy will keep you up and online. Sizing matters somewhat. Having excess horsepower that sits unused is extra money spent on one box that could have been applied to scale out redundancy. If you can size one machine to match your current and projected workload, then if there are two, or more, of these and one fails the remaining can shoulder the load while you get the broken one back up. Where the balance point is struck will depend on workload. Let's say (hypothetical) one box as a web/database server can handle 1,000 connections/users per second within desired latency and response time. If a spike in demand suddenly comes that box will slow to a crawl (or even fall over) as it tries to keep up, as it is lacking the extra horsepower overhead that would otherwise be sitting idle if it did. Scaling out (horizontally) by adding more boxes will distribute this spike across multiple machines and remain within the desired processing response/latency time so together they can handle 2,000 when the need is present. Need another 1,000? Add another box, and so on. So the trick is to understand your workload. Don't go overboard on just one huge high-power machine which sits mostly idle and takes you offline if it fails. Spend the money on more moderately sized boxen. Me, I like to have at least 3 of everything (if I can) such that they are sized so that 2 of them together can easily handle the desired load. The third one is for redundancy and the 'what-if' spike in demand. Another advantage here is you can take one offline for updates, then put it back online and test it out for problems. If there is no problem then you can take one of the other two down and update it. This way you can do updates without your service being offline. But the trick is still to understand your specific workload first, then spread the money around accordingly. -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Re: Max top end computer for Freebsd to run on
You mean like a high end rack mount server that's FreeBSD's primary use? One catch about ram, the faster ram comes in smaller sticks. I have four 8Gb sticks for 32Gb, but it's not the fastest ram. The fastest ram tends to be 2Gb sticks. At the moment, FreeBSD's set to a max of 64 cores on amd64, that's threads for Intel, but it can be changed if you actually need it. Newegg has a quad socket xeon 4U system that has a total of 40 cores/80 threads, and comes with 128GB of ram. It will set you back over $30k. You'll need to make a compromise about memory and cpu. A lot of games aren't overly multithreaded because most people aren't even quad core yet. The fastest per core processors aren't the fastest overall. Look at cpubenchmark.net's top speed page and compare it to the single threaded page. Which do you think will do a game better and which will do 100 jails better?
