This document discloses high performance data storage solutions. In an aspect, some solutions can be employed in a cloud-computing environment that provides shared storage for a plurality of customers. In other aspects, the solutions provided by some embodiments can provide multiple tiers of storage, each having a different performance level. This feature can provide a customer with the ability (e.g., through a web portal) to design its own custom storage solution that blends multiple tiers of storage at different capacity and performance levels to attain an optimal level of capacity, performance, and cost. Some disclosed solutions provide a novel arrangement of different types of storage devices that are provisioned through a common API, which can access each storage device's native management interface, as well as the host computer for which the storage will be provisioned, to allocate multiple tiers of storage to the host computer in an automated manner.

Methods and apparatuses to manage working states of a data processing system. At least one embodiment of the present invention includes a data processing system with one or more sensors (e.g., physical sensors such as tachometer and thermistors, and logical sensors such as CPU load) for fine grain control of one or more components (e.g., processor, fan, hard drive, optical drive) of the system for working conditions that balance various goals (e.g., user preferences, performance, power consumption, thermal constraints, acoustic noise). In one example, the clock frequency and core voltage for a processor are actively managed to balance performance and power consumption (heat generation) without a significant latency. In one example, the speed of a cooling fan is actively managed to balance cooling effort and noise (and/or power consumption).

A method, an apparatus, and a computer program product for wireless communication are provided in which downlink transmission modes in a wireless network are semi-statically configured for a mobile terminal in multiple-input multiple-output (MIMO) operation. The apparatus provides multiple precoding matrix indicators (PMIs) for a plurality of ranks. The provision of multiple PMIs by the apparatus enables balanced performance among different ranks and avoids less than optimal performance observed when the apparatus provides only a single rank and PMI that are generally not optimal for all transmissions. Feedback configuration information received by an apparatus defines a plurality of channel state information feedback instances conditioned on an admissible rank value. Rank indicators (RIs) and PMIs corresponding to the feedback instances are determined and feedback is provided for the channel state information feedback instances.

The invention discloses an erasing method of a memory block, which comprises the steps as follows: tendency between recovery efficiency and wear leveling is dynamically regulated according to degree of wear uniformity of a memory block containing invalid data to acquire a cleanness index value of the memory block, and then the memory block to be erased is determined according to the cleanness index value for data erasing. The invention further discloses an erasing device of the memory block, which comprises a dynamic regulation module, a cleanness index module and an erasing module. By providing a new calculation method of the cleanness index, the invention introduces a new parameter, which causes the wear leveling among blocks to be still effectively calculated when erasing times of the block approximates the erasing limit. Meanwhile, a dynamic regulation method is provided to dynamically regulate the tendency between the recovery efficiency and the wear leveling according to the degree of wear uniformity, thus ensuring that the garbage collection of a flash memory has more balanced performance and adaptive ability.
