We have a two node failover cluster configuration:

IBM X-series 365

RAM:4GB

2X2.7GB Xeon

System running on RAID 1 IBM 6M Controller

Storage groups are stored on SAN:

SG1 167 GB

SG3 67GB

SG4 208GB

SG2 305GB

with 3800 user mailboxes.

We recently got an average memory usage of 87% 3500MB out of 4096MB.

We have the folowing settings in the boot.ini /3GB /USERVA 3030 /PAE.

We see an average memory usage of RAM for the folowing processes:

store.exe --- 1300MB

mad.exe --- 400MB

smex_master.exe --- 300MB

services.exe --- 260 MB

inetinfo.exe --- 130 MB etc.

In total atm32 tool from Tmurgent Tech. displays an average of 3500 MB usage

from RAM.

We use TDP for Exchange for backing up the storage groups.

How can we calculate whether our system resources are enough to handle the

load

for the 3800 user mailboxes?Is there any way to detect that there is any

critical resource low on our system?What should we check in order to decide

that our processing power is enough to handle these storage groups?

There's no way to calculate. But you could use the Microsoft Exchange 2007

Load Generator (LoadGen) to run a sample user load, and Microsoft Exchange

2007 Jetstress to validate the storage subsystem.
