Network Setup

I'm looking to redo my hosting system and looking at the possiblity of splitting up services among two servers.

If it was plausible i would have a server for each service, but for now I think i'm limited to two machines.

I'm looking for some input on how i should split the services.
Apache(web), Bind(dns), wuftpd?(ftp), ??(email, pop3/smtp/imap)

There might be some other things, me sleepy at the moment *yawn*

Currently they all share the same box, win32, most likely will have linux running on both boxes.

Well... I would have 2 machines, both running the same thing - if one goes down there is one to take its place, where as if apache is one one, and bind on the other... if bind goes you site is down, if apache goes your site is gone....

think about what you want, do you have a high bind server load? apache need more room?

If i was to run them both as the same thing, some sorta load-balancing or mirror would it be easy? Not sure if you know much about linux, I dont, i figure it would be easier to mirror one machine to another with linux, but how continuously or when something changes i guess would be the question. I figure some kind of a cronjob but thats only at certain times, rsync maybe. I dont know these are just some of the things i've heard or read in my limited linux experience.

Downages should be much of a problem.. I've had the current Win2k box running for 160+ days, system, router, modem all on APC battery backups. http://uptime.netcraft.com/up/graph/?host=gto.dynu.com

They don't need to be mirrors. Simply put - if one goes down for an upgrade, then the other is still standing.

And if you have an uptime of 160 days on a Win2k box you are doing something very wrong. The last few patches require you to reboot to install them (Unless you didnt?) and uptime isnt something to brag about, noone cares if you box has been up 6 months, its the % they care about.

But having a machine standing while one is upgraded wouldnt do much is the sites are on the machine being upgraded, but if they were on both then when request to one fail the other could pick them up.

What ur saying runs me into the problem u mentioned where the one machine is running but something isnt working because the other is broke, either bind or apache.

I did everything short of a complete cycling of the power, no problems.

I guess you could say for the pass six months i've had 100% uptime

Maybe you can clarify what you mean.
Thanks

Well... only you know what you want, do you want something that can handle a lot of traffic? or something that will have 100% uptime?
