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.

Data storage system and method for monitoring and controlling the power budget in a drive enclosure housing data storage devices

A system for data migration between high performance computing architectures and data storage disks includes an intermediate data migration handling system which has an intermediate data storage module coupled to the computer architecture to store data received, and a data controller module which includes data management software supporting the data transfer activity between the intermediate data storage module and the disk drives in an orderly manner independent of the random I/O activity of the computer architecture. RAID calculations are performed on the data prior to storage in the intermediate storage module, as well as when reading data from it for assuring data integrity, and carrying out reconstruction of corrupted data. The data transfer to the disk drives is actuated in sequence determined by the data management software based on minimization of seeking time, tier usage, predetermined time since the previous I/O cycle, or fullness of the intermediate data storage module. The storage controller deactivates the disk drives which are not needed for the data transfer.

RAID calculations are performed on the data prior to storage in the intermediate storage module, as well as when read therefrom for assuring data integrity, and reconstruction of corrupted data. The data transfer to the disk drives is actuated in a sequence determined by the data management software based on predetermined criteria. The RAID capability is complimented with a real time adaptive RAID stripe size selection depending on the overall capacity of 'healthy' components capable of supporting data striping both for RAID 5 and RAID 6 configurations.
