How many servers is your big board on?

My two largest forums are on 2 servers each. What is your set up like and with how many servers?

Normal activity is now about 650 members/non-members online during peak hours, still no major issues.

I did get our server configured with 3.25G of memory, which has helped. Well, that and George (aka "eva2000") having helped configure my.cnf to keep it running efficiently. I have four tables as InnoDB, which really cleared up the table locking problems we've had. We're running a Celeron 2.8GHz right now, which isn't ideal, but it IS working well for us, and within our budget (fueled 100% by donations).

wow , mind sharing some of the my.cnf file? ive been getting deadlocks every few days it seems and i usually only have 50-60 members online at once. and the forum is the only major site on the server with heavy database usage.

either way, im running a P4 2.8 ghz w/ HT, 1024mb ram, 120 sata single drive and it runs smoothly, just get that deadlock once in a while for some reason.

Web
Dual Xeon 2.4 GhZ
4 GB RAM
2x 80 GB 7.2K IDE HD Non-Raid

DB
Dual Xeon 2.8Ghz
4 GB RAM
4x 36 GB SCSI HD RAID 10

Table Locks are fun
Except that it seems to work fine, though I am a bit concerned about CPU load on the webserver which seems to be too high - 400+ Plugins might be too much.
When this starts to cause problems i might have to go back hacking the files.

Is there a performance gain on multiple servers vs. a large multi-processor box? For example are you really better off with two dual proc boxes vs. a quad proc box? I am starting to see quad boxes going for around 450US a month. In a few more years we'll probably have quad proc dual core boxes for under 400US a month so wouldn't that be more than enough for a huge board?

68 votes with 50% of them being only 1 server. Very interesting.

Everyone's concept of the "big board" is different.

I personally think the one server one of my boards is on isn't sufficient... Its getting rather sluggish

curious to which 4 tables you have as InnoDB....

Those that have multiple web servers, how are you spreading the load ? - simple round robin dns or some other method ?

We use a Cisco CSS to spread the load across our web servers. Initially we used round robin DNS but if we need to drop a single/group of sites from certain web servers we had to manually edit the zone files. We normally serve all of our sites from the full number of web servers except when we have a denial of service attack. We try to make the attack not affect other sites while we work on mitigating it.
