HP BL465c Configuring the HP ProLiant Server BIOS fo Low Latency OS Kernel Env - Page 10

Additional low latency recommendations HP servers are configured by default to provide the best balance between performance and power consumption. These settings may not provide the lowest latency. Additional settings that assist in obtaining optimal low-latency performance are accessible through RBSU. Consider the following options as part of any deployment in low latency OS kernel environments: • Set the HP ProLiant Power Regulator Mode to Static High Mode. • Disable Processor C-State Support. Options depend on HP ProLiant server model and generation. C- State Support options include the following: o C1E Support o AMD C1 Halt Support o Any other C-State modes, such as C3 or C6, that are enabled by the BIOS • On HP ProLiant G6 servers utilizing Intel® Xeon™ processors, disable QPI Power Management. Starting with HP ProLiant G6 servers that utilize Intel™ Xeon® processors, setting the HP Power Profile Option in RBSU to Maximum Performance Mode sets these recommended additional low latency options for minimum BIOS latency.
