Lenovo HX3510-G Installation And Service Manual page 61

Lenovo recommends the following BIOS optimization settings to be used with the Lenovo Converged
HX Series appliances.
• Direct cache access (DCA)
You should enable DCA mode for the processors to allow the network adapters to place data directly into
the CPU cache which reduces cache misses and can improve performance.
Use the OneCLI system tool, or other means, to enable the DCA processor option:
onecli config set Processors.DCA Enable
• Operating mode
You should change the operating mode from the default mode to "Custom Mode". This permits other
settings to be changed such as the power performance bias.
Use the OneCLI system tool, or other means, to set the operating mode:
onecli config set OperatingModes.ChooseOperatingMode "Custom Mode"
• Power performance bias
This option allows the OS (hypervisor) to control the node power. Many customers prefer this setting
as it saves on OPEX.
Use the OneCLI system tool, or other means, to set the power performance bias to "OS Controlled":
onecli config set Power.PowerPerformanceBias "OS Controlled"
Step 9. Modify boot options.
Use the OneCLI system tool, or other means, to configure the boot order as follows:
1. CD/DVD Rom
2. Hard Disk 0
3. PXE Network
onecli config set BootOrder.BootOrder="Legacy Only=CD/DVD Rom=Hard Disk 0=PXE Network"
Step 10. Restart the server.
