Applicable Systems All PowerEdge systems running on Intel processors.
--ProcHwPrefetcher/--hwprefetcher
Valid Arguments
• On systems prior to 12G
: enable, disable
• On 12G and later systems
: Enabled, Disabled
Description
Enables or disables the hardware prefetcher. Processor preempts
what data might be needed next, when set to enable. When some
data is found, it loads several steps in advance.
Processor does not preempt, when set to disable.
This option can be replicated.
Example:
A:>syscfg --hwprefetcher=enable
hwprefetcher=enable
Applicable Systems All PowerEdge systems.
--ProcVirtualization/--virtualization
Valid Arguments
• On systems prior to 12G
: enable, disable
• On 12G and later systems
: Enabled, Disabled
Description
Enables or disables virtualization in the CPU. When set to enable, it
enables the additional hardware capabilities provided by Virtualization
Technology in applicable CPUs.
When set to disable, it disables the additional hardware capabilities
provided by Virtualization Technology.
This option can be replicated.
Example:
A:>syscfg --virtualization=enable
virtualization=enable
Applicable Systems All PowerEdge systems
--QpiBandwidthPriority/--qpibandwidthpriority
Valid Arguments
• On systems prior to 12G
: compute, io
• On 12G and later systems
: InputOutput, Compute
Description
Sets the bandwidth priority to compute or io. Set to compute for
computation-intensive applications. Set to io for I/O intensive
applications. This option can be replicated.
