Abstract: A method for determining power consumption in a data storage system is provided. The method comprises determining data access patterns for at least a first storage device in a storage system based on operations performed by the first storage device; and calculating power consumption for the storage system by interpolating costs associated with the operations performed by the first storage device, wherein the cost associated with each operation is determined based on: (1) various levels of activities for the first storage device and a mix of workload characteristics, and (2) predetermined power consumption measurements obtained from one or more benchmarks for same operations performed by a second storage device in a test environment.

Abstract: A method to store point-in-time data, comprising establishing a block size, providing source data storage comprising (S) blocks, and target data storage comprising (T) blocks. The method configures (B) source storage segments and (B) target storage segments, and receives updated point-in-time data for original point-in-time data written to an (i)th source storage segment. The method then determines if a (j)th target storage segment comprises available storage capacity to store the original point-in-time data. If a (j)th target storage segment comprises available storage capacity to store the original point-in-time data, the method writes the original point-in-time data to that (j)th target storage segment.

Abstract: A method, apparatus, and computer program product for thin-provisioning of storage in a storage system by an adviser is provided. A workload profile of the storage is created from performance data. The workload profile includes a measurement of changed data per a predetermined time and resource utilization data over a period of time. A capacity estimate is derived from the measurement of changed data per a predetermined time. A placement estimate is derived from the resource utilization data obtained over a period of time. A target capacity is recommended to a user based on the capacity estimate. A placement location is recommended to a user based on the placement estimate. A predicted resource utilization is provided to the user based on the capacity estimate or the placement estimate.

Abstract: An apparatus, system and method to optimize load distribution across logical and physical resources in a storage system. An apparatus in accordance with the invention may include an availability module and an allocation module. The availability module may dynamically assign values to resources in a hierarchical tree structure. Each value may correspond to an availability parameter such as allocated volumes, current resource utilization, and historic resource utilization. The allocation module may serially process the values and allocate a load to a least busy resource in the hierarchical tree structure based on the assigned values.

Abstract: A mechanism for selectively disabling and enabling read caching based on past performance of the cache and current read/write requests. The system improves overall performance by using an autonomic algorithm to disable read caching for regions of backend disk storage (i.e., the backstore) that have had historically low cache hit ratios. The result is that more cache becomes available for workloads with larger hit ratios, and less time and machine cycles are spent searching the cache for data that is unlikely to be there.

Abstract: Provided are techniques for transmitting blocks of data. It is determined whether any high priority out of sync (HPOOS) indicator is set to indicate that a number of modified segments associated with a block of data are less than or equal to a modified segments threshold. In response to determining that at least one high priority out of sync indicator is set, one or more sub-blocks of data in the modified segments associated with the block of data and with one set high priority out of sync indicator are transferred.

Abstract: A method and system for determining and compensating for phase and time errors in an optical receiver. The method and system includes use of a measurement and reference signal; deriving phase and time errors; and providing compensation values to the optical receiver. The operating frequency and/or other operating parameters associated with phase and time errors are determined and recorded to allow for proper compensation to the optical receiver.

Abstract: A satellite crash sensor for use in a noisy area such as a crush zone has a crash dependent clock that uses an accumulated velocity signal derived from the acceleration signal, rather than the acceleration signal itself, to determine initiation and counting of the clock count. Successive velocity values are accumulated in an accumulated velocity value that is limited between zero and a maximum limit value. The clock count is incremented away from an initial zero value when the accumulated velocity value is greater than zero and back toward the zero value when the accumulated velocity value is equal to zero. The clock count is used as a measure of time from initiation of a possible crash event in the generation of a restraint deploy indicating signal in the satellite crash sensor.

Abstract: A vehicle satellite crash sensor includes a microcomputer with a stored datum indicating intended use in a frontal application such as the front crush space or a side application such as a vehicle side door. The microcomputer also stores a program that processes a sensed acceleration signal, derives an oscillation value and derives an occupant restraint deployment signal at least in response to the oscillation value. The program includes stored code for two alternative oscillation derivation algorithms: one of which is used in frontal applications and derives an integral of the absolute value of the sensed acceleration signal; the other of which is used in side applications and derives an integral of the sensed acceleration. The stored datum determines which of the stored oscillation algorithms is used.

Abstract: A satellite crash sensor for a motor vehicle occupant restraint system that provides multi-stage deploy signaling in a manner that detects a second stage deploy crash event having an initial velocity rise followed by a loss of velocity that delays the continuation of the velocity rise. The sensor derives a velocity value from an accelerometer signal. The initiation of a possible crash event is detected and a clock count indicating a time progression into the event is initiated. A constant second stage threshold value and data defining a first stage threshold varying as function of the clock count are stored. Only for a time indicated by a first predetermined value of the clock count, a second stage datum is stored if the velocity exceeds the second stage threshold value.

Abstract: A method and apparatus for end jointing timber members such as floor or ceiling joists by means of spiked timber connector plates, using apparatus incorporating equipment to position and hold the timber and automatically feed connector plates from cassettes or magazines holding a supply of connector plates onto magnetized pressing platens which then rotate to position the connector plates to span the joint to be made before passing the spikes into the relevant timber members.
