Windows SBS 2011


My client, which has about 15 minutes is running SBS 2011 on a Fujitsu TX100 - 32Gb RAM

We have recently upgraded the RAM from 16 to 32Gb and noticed exchange is using 20Gb of this. The exchange database is running at 59Gb.

Is this something I should be worried about?

I have also noticed a couple of IIS services running high also, is this right? (I know exchange integrates with IIS)

exchange is very resource hungry and it will keep on using loads.

Hi Ryan,

Exchange will use as much memory as you will give it. It reserves an amount of memory, whether using it or not to optimise performance.

There are some articles explaining how to reduce this if it is causing contention:

Excellent, thanks for this, I have set this to 8Gb for now - 262144

Do I need to set the CacheMinSize also do you think?

thanks again
Guy LidbetterCommented:
Yes, Definitely set the minimum.

@Kash - Always moving on to better places ;-p

What are the IIS services running high? w3wp.exe? They are worker processes in IIS on an exchange sbs box unless the w3wp.exe process is killing the machines performance visibly you can leave these.

On production big site web servers however this would be a different matter.

So youve capped exchange to 8GB?

Also word of advice, ive worked for some pretty terrible companies who had pretty terrible sales guys buying servers like this. Without being too harsh these servers are not fit for use imo. The raid card and everything else is very very sub standard, your customer is essentially using a desktop pc.
I would actually recommend a HP Elite Desktop with Raid config added to run SBS rather than this machine.

For the sake of the business regardless of the margin someone is trying to inflict on a customer selling these things, this should never be done actually, very poor hardware dished out here.

To be fair the server was installed when they had 4 users. they have grown fast over the fast year so a new server will be on the way, but thanks for your comment!

Dont take it personally, just my 2 cents and i know a lot about small to mid MS companies.

If they have 2 users, there in the cloud or on a proper server, that is just my way of thinking.

any issues with this let me know.
