Website/Database/Exchange Server Hardware Setup Question

[TH3ROOKIE]

Hi all,

I plan on changing the setup of our website. Currently, I have 1 server that handles IIS, 1 server that handles MySQL and 1 server on standby with both ISS and MySQL configured in case server A or/and B goes down. I also have a small NAS to handle backups. I'm planning to add an Exchange server to that and wanted at the same time changing the way the website is handled by those two machines.

My first idea was to have a cluster of 4 server with 3 virtual servers (1- IIS and DNS, 2- MySQL, 3- Exchange)

or

Individual servers with load balancing on the 4th.

Our budget is tight and right now, I'm not experienced with HA setups.

I'm looking for suggestions.

Thanks

ISS?? You mean IIS? You clearly state website, so you mean IIS?? I don't know of any httpd that is called ISS?

Running 1 physical box with 3 vms on it and then using the host as a backup -- ie the 4th would not be a HA setup at all.

is this what you mean when you say a 4 cluster?

What physical hardware are you working with?

Hi,

Yes, my mistake. I edited my post. It's IIS 7.5. Right now, I have 2 Dell 2850 with one 1950. Considering on switching to 4 Dell 2950 with 2 Xeon 5320 QC 8GB Ram to run either a HA cluster or LB cluster. Not sure which one is best for a website and MySQL database for perf and availability.

Thanks.
