Scaling up the ASP.NET session state server

Question

Scenario:

The website is hosted on three servers using IIS on each.

All three servers are clustered using the network load balancing software that comes with Windows Server 2003.

All three sites are configured to store the session state on a separate server that has been designated as a "state server".

I have been asked to scale up the "state server". Is there a way that I can have more than one state server and synchronize state between them, so if one of the state servers goes down the others will be able to serve the state information?

Answer 1

We use Scale Out State Server for this where I work, and it does the job wonderfully and is dead simple to set up. I understand Microsoft is also working on a similar product called Velocity, but I don't have any experience with it.

The only downside to SOSS is that you've got to pay for it - but I've had nothing but great experiences interacting with their sales and support team. If you end up licensing, do me a favor and let them know that Daniel from Gratis sent you ;)
