Abstract: Described is a storage system and method for managing and optimizing power consumption in a storage system. Logical devices are mapped to physical disk drives. A plurality of power profiles is defined. Each power profile is associated with a mode of operation for a physical disk drive. One of the power profiles is assigned to each logical device. One of the physical disk drives is identified for which every logical device mapped to that physical disk drive has been assigned the same power profile. The identified physical disk drive is operated in the mode of operation associated with said same power profile. The mapping of the logical devices to the physical disk drives may be changed in order to group logical devices assigned the same power profile onto the same physical disk drive.

Abstract: Described is a storage system and method for reducing power consumption in a storage system by shortening seek distances associated with input/output (I/O) requests to a physical disk drive. A sweep direction is set. An offset of a new I/O request is evaluated to determine whether to send the new I/O request to the physical disk drive. The new I/O request is sent to the physical disk drive if the offset is consistent with the sweep direction. Otherwise, sending the new I/O request to the disk drive is deferred until the sweep direction is set to a reverse direction.

Abstract: Described is a process and device for accessing data stored in multiple logical volumes. The data are replicated on first and second storage elements, such as the redundant hard disk drives of a disk mirror. The multiple logical volumes are divisible into a first logical volume and a second logical volume. All read requests targeting the first logical volume are directed to one of the first and second storage elements. Read requests targeting the second logical volume are asymmetrically interleaved between the first and second storage elements. An asymmetric interleave ratio is determined and implemented that substantially balances the read requests to the multiple logical volumes between the first and second storage elements.

Abstract: Described are techniques and criteria used in connection with cache management. The cache may be organized as a plurality of memory banks in which each memory bank includes a plurality of slots. Each memory bank has an associate control slot that includes groups of extents of tags. Each cache slot has a corresponding tag that includes a bit value indicating the availability of the associated cache slot, and a time stamp indicating the last time the data in the slot was used. The cache may be shared by multiple processors. Exclusive access of the cache slots is implemented using an atomic compare and swap instruction. The time stamp of slots in the cache may be adjusted to indicate ages of slots affecting the amount of time a particular portion of data remains in the cache.
