Server Requirements Question

  Asked By: Ralph    Date: Nov 03    Category: MOSS    Views: 3387

I am working on ordering several servers for our MOSS 2007 deployment. I
have been doing some research and it is recommended that the front end
web servers have a minimum of 4 GB (8 GB is optimized). I am trying to
convenience the powers that be to get 8GB servers instead of 4 GB. Can
anyone help me with my argument?

Since the majority of the processing is done on the SQL servers will it
matter if I get the 4 GB server instead of the 8 GB server. Any advice
would be greatly appreciated.

My general advice is always to scale out before scaling up and an extra
server for additional processing and availability is always a good
choice .... just not as cheap as adding more memory to the other

However, another thing that I've found useful is not to add the memory
at the start if you are uncertain but to advise that the additional
memory may be required once the project goes live - i.e. they should
reserve some money for this but you are not seen as a profligate
spender. That way, if the memory is not needed you are seen as cautious
and if it is needed you are seen as protecting the companies money but
with a handle on whats required.

What would (do) you recommend for a base installation for MOSS, when it's
replacing an SPS2003 medium server  farm? (! WFE, 1 Index/Job, 1 SQL box).
My experience in testing so far has been more RAM is better as this version
seems to be very RAM intensive. Another consideration is the perception to
the business if it becomes apparent that the current configuration is
lacking - slow response and processing times ....

Well, if you have an existing farm in place then we'd go through the
logs etc and baseline that farm to see how its performing and then make
recommendations from there.

MOSS is a web based applications and, generally, is sized from the front
end on the number of requests per second made to the front end servers  -
the more often it is being "hit" and the more complicated the pages etc
then the more requests per second and the more processing power and
memory you need.

General advice is split sql off first, then add a second web front end,
then split off the index

This gets you to your traditional medium size farm where you are at
right now. From there it really is a matter of how your are using MOSS -
multiple SSPs with lots of indexing, add another index server, lots of
searching, split off the query, lots of forms, add dedicated forms

As you can see, from the above its very difficult to give advice other
than to look at how your present farm is put together, if the
performance is acceptable, whether you are going to stay with the
present structure and services or change and where you believe bottle
necks are occurring.

My comments about scaling out rather than up is generally around 32 bit
its true but if you are going 64 bit then you can take advantage of
having more memory on the front end if that suits your environment as 64
bit brings significant gains in performance if you add more memory.

The more memory the better. However going above 4gb make only sense if you use
Windows Server 2003 64bits edition.

You will have to be careful because if your requirements  call for indexing PDF,
you will still need to keep a 32 bits indexer in your farm as Adobe is yet to
release a 64bit Ifilter.

Just so everyone knows, I think FoxIt have a 64 bit pdf ifilter
available for download
Not tried it myself but their other pdf stuff is fantastic
You can see the page yourself at
and download the software from

I'll give the FoxIt ifilter a try as well.

Now there's a bit of serendipity for you
HP have just released their SharePoint sizing tool

Answer #8    Answered By: Bobbie Rodgers     Answered On: Nov 03

I agree that you should scale out, and then up. Except, if you have an
Internet-facing implementation then you must buy an External connector
license for every server  in the farm. Now, this license isn't cheap and
could be a reason for scaling up.

I've checked and the tool is still for 2003.

There is a nice pdf sizing guude for 2007 tho which I guess is the new bit
