Abstract
A control processor manages the power budget in a drive enclosure and is within the drive enclosure which monitors in real time a redundantly configured power supply unit, drives, interposers, and temperature sensors, and determines the power settings for each drive to avoid overload and overheating in the system. The control processor dynamically adjusts the mode of operation as needed during operation through the SAS interposer. A localized monitoring and control mechanism eliminates the need for extraneous coordination of information across various entities that access the storage. Data tunneling takes place directly between the compute nodes and target drives through the SAS expander and interposer, and does not need buffering the pending IO requests in the DRAM.
