Filed:

Feb 10, 2003

Appl. No.:

10/361387

Inventors:

David P. Goodman - Loveland CO, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15/173

US Classification:

709224, 709201, 709220, 709223, 711114

Abstract:

Method and apparatus for limiting access to control units channel-connected to host computers through a FICON switch. The control unit port of the FICON switch receives a requests from an attached host to provide configuration information regarding the switch ports. The control unit port deliberately misrepresents the port configuration of the switch by reporting that ports outside the zone of the requesting host are not installed, even though these ports may in fact be installed for use by other hosts that belong to other zones.

International Classification:

G06F 17/30

US Classification:

707646, 707649, 707E17005, 707E1701

Abstract:

Embodiments of the present invention provide an approach for protecting and restoring data within a networked (e.g. cloud) storage computing environment through asynchronous replication and remote backup of data and its associated metadata. Under embodiments of the present invention, data backup and recovery functionality provides data backups by detecting incremental updates to the data and its associated metadata at specific points in time determined by policies. The policies are configurable based on user requirements. Multiple copies of the data backups can be made and stored in separate compressed files at backup/disaster recovery locations. The backups of data and its associated metadata, which includes file system configuration information can be used to restore the state of a computer file system to that of a given point-in-time. Accordingly, a data protection approach is disclosed for protecting data at both the file system level and application level.

International Classification:

H04L 29/08

US Classification:

709226

Abstract:

Embodiments of the present invention provide an approach for intelligent storage planning and planning within a clustered computing environment (e.g., a cloud computing environment). Specifically, embodiments of the present invention will first determine/identify a set of storage area network volume controllers (SVCs) that is accessible from a host that has submitted a request for access to storage. Thereafter, a set of managed disk (mdisk) groups (i.e., corresponding to the set of SVCs) that are candidates for satisfying the request will be determined. This set of mdisk groups will then be filtered based on available space therein, a set of user/requester preferences, and optionally, a set of performance characteristics. Then, a particular mdisk group will be selected from the set of mdisk groups based on the filtering.

International Classification:

C07D 311/80
B01D 9/00

Abstract:

A Reflux Rinsing method for purifying crystals using solvent vapor through dynamic equilibrium recrystallization. Feed material having tetrahydrocannabinol (THC) is inserted into a reaction vessel having walls, and upper portion, and a lower portion with a bottom surface. The feed material is exposed to a hydrocarbon liquid in the reaction vessel in a quantity sufficient to keep liquid present in equilibrium with gas in the reaction vessel through the recrystallization process, forming a raw extract having THC. The walls and bottom surface of the reaction vessel are coated with raw extract. The reaction vessel is heated and then the heating is discontinued. Vapor/thin-film DER is promoted in the reaction vessel for a predetermined length of time with no solvent reflux, resulting in formation of purified crystals of THC acid under pressure. The hydrocarbon solvent is reclaimed from the reaction vessel, leaving the purified crystals and impurities. When the reaction vessel is opened, the purified crystals and impurities are removed.

International Classification:

H04L 12/801

US Classification:

709224

Abstract:

Embodiments of the present invention provide approaches (e.g., online methods) to analyze end-to-end performance issues in a multi-tier enterprise storage system (ESS), such as a storage cloud, where data may be distributed across multiple storage components. Specifically, performance and configuration data from different storage components (e.g., nodes) is collected and analyzed to identify nodes that are becoming (or may become) performance bottlenecks. In a typical embodiment, a set of components distributed among a set of tiers of an ESS is identified. For each component, a total capacity and a current load are determined. Based on these values, a utilization of each component is determined. Comparison of the utilization with a predetermined threshold and/or analysis of historical data allows one or more components causing a bottleneck to be identified.

International Classification:

G06F 3/06

US Classification:

711114

Abstract:

The present invention provides an approach for automatic storage planning and provisioning within a clustered computing environment (e.g., a cloud computing environment). The present invention will receive planning input for a set of storage area network volume controllers (SVCs), the planning input indicating a potential load on the SVCs and its associated components. Configuration data for a set of storage components (i.e., the set of SVCs, a set of managed disk (Mdisk) groups associated with the set of SVCs, and a set of backend storage systems) will also be collected. Based on this configuration data, the set of storage components will be filtered to identify candidate storage components capable of addressing the potential load. Then, performance data for the candidate storage components will be analyzed to identify an SVC and an Mdisk group to address the potential load.
