In case you haven’t done so already and are experiencing performance related issues with a Dell PowerEdge M620 blade server, you may want to BIOS System Profile Settings.
You can access the console of the M620 blade server via the Chassis Management Controller. In the left hand side menu, under Chassis Overview section, Server Overview, click on the blade server you want to access. Then select the Launch Remote Console button.
Restart the server. During the boot up press the F2 key for System Setup.
Select the System BIOS menu option.
Next, select System Profile Settings.
The default setting for System Profile in System Profile Settings is Performance Per Watt (DAPC). We’ll change this to Performance.
Note that CPU Power Management has been changed to Maximum Performance, and C1E and C States have been disabled. These cause the CPU to be throttled. When the CPU is idle it can be instructed to conserve energy by entering a low powered state. Several different “states” exist. For example C1E state (for Intel’s CPUs) called “Enhanced Halt”, is software controlled and essentially reduces CPU voltage and stops CPU main internal clocks. All these various states are referred to as C States.
Click on the Back button, then hit Finish, and when prompted to Save Changes select Yes.
Reboot the server.
