The Basic Input and Output System (BIOS) is a non-volatile firmware stored in the system ROM of a server. It is used to perform hardware initialization during server booting and provide runtime services for the operating systems. As shown in 图1-1, the BIOS interacts between the server hardware and the operating system (OS).

4 Workload profiles (for the R6900 G5 only)

4.1 Introduction

A workload profile is a set of configuration options to deploy BIOS settings for server applications. The BIOS provides several profiles to match the selected workload. You can find the Workload Profile Configuration item from the Advanced > Miscellaneous Configuration screen.

These profiles include:

· General Power Efficient Compute

This profile applies the most common performance settings that benefit most application workloads while also enabling power management settings. In this profile, the CPU core can enter power efficient state, the processor chip can stay in sleep mode, and virtualization is usually disabled.

· General Peak Frequency Compute

This profile is a set of performance-first options. In this profile, power efficient options are disabled to keep all CPU cores staying in C0/C1 state, and virtualization is disabled as well.

· Advanced Reliability Mode

This profile is intended to improve maintainability. With performance policies, the latency for waking up CPU can be reduced, and the response time for system errors can be shortened. As a best practice, use x4 memory chips and enable ADDDC Sparing. If you use x8 memory chips, ADDDC is not supported.

· General Throughput Compute

This profile is intended to be used for workloads where the total maximum sustained workload throughput is needed. Increased throughput can occur when the processor is able to perform sustained work across all available cores during maximum utilization. When SNC is enabled, the average latency to LLC is reduced. Best throughput is achieved when the workload is also nonuniformed memory access (NUMA) aware and optimized.

· High Performance Compute

This profile is intended for clustered environments where each node performs at maximum utilization for extended periods of time to solve large-scale workloads. When virtualization environment is not used, virtualization IO support will be disabled to ensure high performance. Power management is disabled in favor of sustained available bandwidth and processor compute capacity.

· Virtualization-Power Efficient

This profile is intended to be used for virtualization environments. The profile ensures that all available virtualization options are enabled and allows the processor chips to go into sleep state. It is a set of virtualization profile in favor of power efficiency.

· Virtualization–Performance

This profile is intended to be used for virtualization environments to achieve maximum performance. The profile ensures that all available virtualization options are enabled. Power management settings are disabled in favor of delivering maximum performance, and virtual nodes runs at maximum utilization.

· Graphic Processing

This profile is intended for workloads that are run on servers installed with GPUs. GPUs typically depend on maximum bandwidth between I/O and memory. Power management features that have impact on the links between I/O and memory are disabled. Peer to Peer traffic is also critical and therefore virtualization is also disabled.

· Low Latency

This profile is intended to be used in an environment that desires the least amount of computational latency. Maximum speed and throughput are often sacrificed to lower overall computational latency. Power management and other management features that might introduce computational latency are also disabled.

· Transactional Application Processing

This profile is intended to be used for business processing environments, such as online transaction processing (OLTP) applications that require a database back-end. It balances the requirement of managing both peak frequency and throughput.

· Custom

This profile uses the default BIOS settings. You can modify the settings as needed. For information about the default settings, see "BIOS menus."

4.2 Workload profile dependencies matrixes

表4-1 through 表4-2 show the workload profile dependencies matrixes, in which an "X" means that the option setting has no requirement for the profile and can be modified.

Not all the options listed are shown on the BIOS. However, the options of profiles default to the values shown here.
