The documentation for JetStress states that Exchange 2007 requires 1GB of RAM for JetStress 256MB / storage group. It seems no matter how much memory I put in this system, JetStress will only allow me to use 11 storage groups. I am using Windows Server 2003 Enterprise x86. JetStress 32-bit 08.02.0060.000. The 4 required files from Exchange 2007 32-bit.

Hi, I have no enough memory to test your situation. Nevertheless, I have a consideration: As your operation system is 32bits, the JetStress will not look for memory over the 4GB boundary. According to the JetStress document: Number of storage group is limited by the physical memory on the computer. Consider installing additional RAM to support more storage groups (256 MB/storage group) Thus, only 11 ((4096-1024)/256) storage groups are available. Mike

I realized yesterday, that was the case. I deployed a virtual machine from the wrong template. I used standard instead of enterprise. Thanks!
