Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 9/46
G06F 3/06
G06F 13/00

US Classification:

718104, 711 4, 711111

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.

International Classification:

G02F001/13

US Classification:

349/201000

Abstract:

A method for producing a diffraction grating is provided. First, a mixture including nematic liquid crystal, dopant, and polymerizable precursor is introduced between two electrically conductive substrates having alignment layers for inducing orientation of the liquid crystal director. A potential difference is applied across the liquid crystal to cause a spontaneous self-assembly of the liquid crystal into an array of convective rolls. Thereafter, the roll structure is stabilized by the creation of a polymeric network through polymerization and/or cross-linking of the polymerizable precursor. The convective roll structure serves as a template for the formation of the polymeric network.

International Classification:

G06F 12/08

US Classification:

711136, 711E12022

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.

International Classification:

G06F 11/34
G06F 7/24

Abstract:

A computer-implemented method according to one embodiment includes identifying aggregated customer performance data for a system resource, creating a first system map for the system resource, utilizing the aggregated customer performance data, comparing the first system map to a second system map created for the system resource utilizing calibration data, and adjusting the second system map, based on the comparing.
