Re: Request for information

Hi Roger,

Working with a partner is the best solution. but the basics are here.

Remember What is the Load on the applications, Developers are always saying it runs on my laptop so no issues here, until it is production.

The IIS section I would do this in a web farm there are good papers on this. But do this in a team with your web site developers not all sites are best designed for NLB.
Two servers with 2 nic's ( LAN /NLB ) for the IIS , with a DFS for the site so you need only to update the website in one location.
Two node Cluster for your mail and SQL. IF this is supported with mailenable.
I think ISCSI is the most flexible solution, make a storage lan, public and private lan all in different IP subnets !! use separate storage switches and lan switches.

But check the sizing what is the primary load on this site the CPU/ Memory is not the main issue here. The under dog is DISK IOPS !!
you can have a 64 core CPU 256 Gb memory but if you have a disk IO from 5000 and you have only a disk set from 10 disk the performance is really bad but with 5000/130=40 disks it rocks.
So It is not only the hardware and software a cluster design / infrastructure design is more the a pile of boxes but use x64 where you can !

In case from the Email product --- not Exchange ;-(

On the mailenable site are nice items about clustering.

I have been asked to provide to my manager a document outlining what is required to create failover clusters for our application servers using Windows 2008.

In particular:

A web-server running multiple sites under IIS using dotnet (32 bit currently)
A mail server
An SQL server

The purpose would be to provide fail-over redundancy to our systems so that if the server in question failed, it's partner would take over. In our wish list, this would all happen automatically and applications would just work. Of course web DNS is done by IP, so whether that is actually possible or not I do not know...

Can you point me to documents that outline the basics of the type of hardware needed.

For example, I know that under win 2008 we require identical servers using hardware components that are Certified for Windows server 2008. I know that we need some type of SAN device. Beyond that I don't know how it all goes together.

For example, since we are looking at 3 clusters of 2 nodes each, can they share a SAN device between the 3 clusters (if it meets certain criteria... and what would that be?) Is there a performance hit if the SAN uses Gigabit Eth. or ISCSI (never used ISCSI not familiar with it).

I am not even sure what questions to ask at this point... so if there are documents that explain this... enought that I can outline what type of hardware (not brands but capabilities) I'd appreciate it.
