IIS Failover

I have two identical servers configured.
I have one Web Site published to one of the servers.
I have been reading up on Clustering technology and had to stop due to a
hardware requirement of "External disk storage unit connected to all
computers".

What I want to accomplish is sounds simple to me.
How do I replicate one web site to the other server in real-time?
And...How can I accomplish failover?(Even if it's manual)

I have separated these two servers from our AD and kept them on a workgroup
and separate network.
They are behind a firewall.
I have been reading about MS Virtual Server R2 (Which I own) but don't think
this is the way to go either.

Can someone pleeeeease point me in the right direction as I have spent a
looooong time on this scenario already. Any/all assistance is much
appreciated. Thank you.

Sincerely,

JoeF

Hi Joe,

Well normally in a scenario where you want to have some sort of fault
tolerance for web servers you would implement NLB.
However this would only work in a scenario where you would have stateless
web servers.

You could also look into clustering since 2 virtual machines using a scsi
controller on bus 6 would support this.
regards,

Niels

Thank you for taking the time to answer my questions. I have two more.

I uderstand stateless protocols, but what would make the web server NOT have
stateless packets? I would like to implement NLB...is there a step-by-step
guide?

I'm sorry, but what do you mean by using a scsi controller on bus 6 mean?
Would I be using Virtual Server AND MS Clustering to accomplish this? What is
configured first?

Thanks again!

Hey Joe,

Well it is not so much the protocols being stateless but the user's session
with the web server.
Why would you want the data between the two web servers copied all the time?
The web servers should be quite static when it comes to data, changes
ideally would be made to a back-end system.
If the web servers hold static content than NLB is a fine solution. A link
on how to set up NLB :

http://www.awprofessional.com/articles/article.asp?p=102021&seqNum=2&rl=1

Virtual Server supports MS clustering.
A prerequisite is that you set up your VM's to use SCSI hard disks on SCSI
host bus 6.
Default SCSI disk will be attached to a SCSI controller on bus 7. So if you
opt for MS clustering first build your VM's and then set up clustering.

I would recommend NLB though, since we are talking about web servers.
Regards,

Niels

I've set up a similar solution a couple of weeks ago, but this has nothing
to do with Virtual Server.
I enabled NLB (Network Load Balancing) to get a simple
load-balancing/failover solution (This works automatically)
I used this in combination with the File Replication feature in DFS
(Distributed File System)
There are a lot of websites with information on how to do this:
