Easy ways to boost the performance of HP Proliant servers, that you might not know
These days a lot of attention is paid to the ecology and green technologies, including manufacturers of servers. Hewlett Packard is not the exception. There are number of parameters in the settings of server's BIOS, which affect the power consumption of hardware. And, naturally, these parameters also affect performance. You may not know this, but these are installed by default settings, significantly reduce the speed of the memory and CPU.
I will show you where these parameters are located. Setting the highest values for these settings helped us to significantly increase the speed of VmWare ESXi hosts and to achieve a shorter response for SAP systems. These recommendations are taken from SAP notes.
HP Power Profile - Maximum Performance. Apparently, this is the most important parameter that affects the performance.
HP Power Regulator - HP Static High Performance Mode.
Intel QPI Link Power Management - Disabled.
Minimum Processor Idle Power Core State - No C-states.
Minimum Processor Idle Power Package State - No Package State.
Intel(R) Turbo Boost Technology - Optimized for Performance.
