HP CIFS Server 3.0f Administrator's Guide verison A.02.03

Memory Requirements
Each smbd process will need approximate 2 MB of memory on 11i v1 and 4 MB on 11i v2. For 2048
clients, therefore, the system should have at least 4 GB of physical memory on 11i v1 and 8 GB on 11i v2.
This is over and above the requirements of other applications that will be running concurrent with HP CIFS.
