High usage on non paged memory pool / clustered system

Hello,

==>Exchange does not support the PAE. You would remove it:

Use of the /3GB switch in Exchange Server 2003 on a Windows Server
2003-based system
http://support.microsoft.com/kb/823440/en-us

Because Exchange Server uses the /3GB switch as it scales up, the Exchange
Server computer cannot efficiently use more than 4 GB of RAM. Exchange
Server does not support instancing, Physical Address Extension (PAE), or
Address Windowing Extensions (AWE).


==>The Same for your Filer:
http://support.microsoft.com/kb/317249/en-us
Heavily stressed file servers should not use /3gb switch. The /PAE switch
alone will not cause any issue.

However, I found in one MS article, that this was true (remove /PAE)
in the past, now it is recommended (or supported), running Exchange
2003 on PAE kernel. For the file server, I think it is right to
remove /3GB, altough I still don't know whether I can have different
boot.ini configuration for the cluster nodes (one running exchange - /
3GB, one running file server services - without /3GB). What about
that?

My second question was, how can I determine, which process is using so
much of Non Paged Memory Pool, I can see only MmCm tag is using 50 MB
of it, but I don't know exactly the preocess name calling this
mechanism of allocation contigouous block of NPP memory.

Maybe I can try to set /USERVA switch to some other value to get some
MB of NPP?

For exchange, as stated in the KB:
Exchange Server does not support instancing, Physical Address Extension
(PAE), or
Address Windowing Extensions (AWE).
=>remove the /PAE on exchange

PAE is useful if you have more than 4G and application that can use it (like
SQL).
You would remove PAE on both node, it's useless for you.

You can have many entries in the boot.ini, choose your default. You will be
able to change manually at each boot.

Start by removing the /PAE on exchange and /3G /PAE on the filer.
This would correct your issue at the root.
ProcessExplorer would be helpful:

However, I found in one MS article, that this was true (remove /PAE)
in the past, now it is recommended (or supported), running Exchange
2003 on PAE kernel. For the file server, I think it is right to
remove /3GB, altough I still don't know whether I can have different
boot.ini configuration for the cluster nodes (one running exchange - /
3GB, one running file server services - without /3GB). What about
that?

My second question was, how can I determine, which process is using so
much of Non Paged Memory Pool, I can see only MmCm tag is using 50 MB
of it, but I don't know exactly the preocess name calling this
mechanism of allocation contigouous block of NPP memory.

Maybe I can try to set /USERVA switch to some other value to get some
MB of NPP?

Okay, If I understood good, you are recommending to use different
boot.ini configuration for each cluster node (exchange, file server),
aren't you?

I am slightly confused of the /PAE, especially from this:

http://technet.microsoft.com/en-us/l...ABootiniSwitch

----
Until recently, it was a best practice to disable PAEs with the /NOPAE
switch on Exchange servers where the /3GB switch was set. This
recommendation existed because Exchange Server 2003 or Exchange 2000
Server had not been tested with the PAE kernel, nor was the PAE kernel
necessary on an Exchange server. New hardware and software
capabilities now require the PAE kernel to be loaded. For example,
servers with Lindenhurst or Twincastle chipsets require the PAE kernel
to be loaded, otherwise not all installed memory will be recognized.
In another example, Windows Server 2003 SP1 supports hardware-enforced
DEP. This functionality cannot be enabled if the PAE kernel is not
loaded.

As a result of testing by the Exchange Server product team, it is now
a best practice to allow the PAE kernel to load on an Exchange server.
Therefore, the /NOPAE switch is no longer necessary unless you are
troubleshooting a specific issue where the PAE kernel is suspected as
a contributory factor. On some servers running Windows Server 2003
SP1, the /NOPAE switch may be ineffective because hardware-enforced
DEP, which is enabled with the /NoExecute switch, will override this
instruction to disable PAE. If required, the /Execute switch can be
used to disable the PAE kernel.

My opinion is that you do not have more than 4G, so your systems don't need
the PAE.
As mentionned in your link, some server with hot-memory need the PAE.
Do you have hot-memory feature?

I would just remove the /PAE to let windows load it if needed.
The most urgent things is to remove the /3G on your filer.

I think not, or, at least I don't need that feature. I will remove
the /PAE and try to remove /3GB from file server.

If it will not help, I will try to play with /USERVA setting, maybe I
will try the 2900 value.
