Abstract: Various systems and methods are presented herein regarding controlling operation of central processing units (CPUs) to reduce power consumption at a data center(s). A first subset of CPUs located on a computer system can be operationally adjusted while a second subset of CPUs can be designated as having to be available at all times with a default operating condition (e.g., to run background operations). As operational demand placed on the computer system reduces, operation of the first subset of CPUs can be throttled back (e.g., clock speed reduced) while the second subset of CPUs remain at the default operating condition. As operational demand subsequently increases respective CPUs in the first subset of CPUs can have their operating condition (e.g., clock speed) increased. By adjusting the operating condition of one or more CPUs, power consumption at the data center can be reduced during periods of low operational demand.

Abstract: A technique involves performing, in a data storage system, a full-boot procedure which includes a set of critical boot activities and a set of avoidable boot activities. The technique further involves providing, in response to completion of the full-boot procedure, a fastboot notification indicating to the data storage system that a fastboot procedure is to be performed in response to a warm boot event. The technique further involves placing, after providing the fastboot notification, the data storage system into a normal operating mode in which the data storage system performs data storage operations in response to data storage requests from a set of external host computers. Such operation enables the data storage system to subsequently perform a fastboot procedure that avoids the set of avoidable boot activities in response to the next warm boot event.
