Appl. No.:

09/372297

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1200

US Classification:

711 4, 714 6

Abstract:

A system for ensuring high reliability in a block service disk array system while promoting high performance by logically writing all changes to strides on the array while physically writing ahead to a log only a subset of the changes. Specifically, for changes of only a strip or so, the changes are written to a log, along with a commit record, and then written to disk, later deleting the changes from the log. In contrast, for relatively larger changes, i. e. , for an entire (or nearly entire) stride, the old stride is not overwritten by the new, but rather is written to a new location on the disk, with the new and old locations and a commit record (but not the new stride itself) being logged and with the entries for the locations in the stride mapping table swapped with each other. In an alternate embodiment, blocks can be written to temporary locations in a RAID-1 area and lazily moved to home locations in a RAID-5 area of an array of disks.

International Classification:

G06F 1300

US Classification:

710304, 710302, 361193, 310325

Abstract:

A hot pluggable system includes an interlock between a component fail detect module and a component lock mechanism, such that the component is locked in place when it operates properly and is automatically released to permit a person to remove the component from the system when the component fails. In this way, the risk of human errors in removing the wrong component is reduced.

International Classification:

H04K 100

US Classification:

713183, 713185, 713168, 713171, 713182, 380259, 380280, 380277, 380278, 380 30, 380284, 707 9, 707201, 707203

Abstract:

A multi-stage login procedure and system involves a first stage in which a login ID and a public key (encrypted) is transmitted from a client computer to a server computer and a key-exchange key (encrypted) is provided from the server computer to the client computer. In a second stage, a first split symmetric key and a server authentication string is generated and encrypted by the client computer and then transmitted to the server computer. In addition, the server computer generates a second split symmetric key and combines the same with the first split symmetric key to obtain a complete symmetric key for encrypting further communications from the server to the client computer. The server also generates a client authentication string, encrypts the same and transmits the encrypted string, the server authentication string (encrypted and incremented) and the second split symmetric key (encrypted) to the client computer. In a third stage, the client computer uses the server authentication string to authenticate the server. In addition, the client computer combines the second split symmetric key with the first split symmetric key to obtain the complete symmetric key for encrypting further communications from the client computer to the server computer.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 9/00

US Classification:

713175, 713157

Abstract:

A system for authentication to support secure data transfer includes a protocol wherein a certificate payload, an ID payload, and a signature payload all respectively contain at least two certificates, IDs, and signatures, concatenated together. The certificates are generated by different certificate authorities (CA) that have no trust relationship with each other. One certificate can be granted to a person and another to a particular host computer intended to be used by the person, so that for secure data transfer to take place, both a certified user and a certified host computer must be involved.

Inventors:

Stephen Paul Morgan - San Jose CA, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 13/12
G06F 13/38

US Classification:

710 62, 710 74

Abstract:

A system and method for using a conventional, unmodified operating system that routinely issues disk I/O requests in a diskless network computer. An adapter receives the disk I/O requests and translates them to network I/O requests, transparently to the CPU. The requests are satisfied using the network. In this way, the operating system need not be modified to issue network calls instead of disk requests.

US Classification:

707755

Abstract:

Methods, program products, and systems implementing dynamic parsing rules are disclosed. Log data from a variety of log producers can be parsed using parsing rules to generate information about an information system. The parsing rules can include system parsing rules and custom parsing rules. A state machine can be used to detect conflicts between various parsing rules. A central server can distribute the system parsing rules and custom parsing rules to one or more remote servers for distributed processing. In a hierarchical parsing system, a first tier parser can be used to identify types of sources generating the log data. Log data from each type of log source can be sent to a second tier parser that corresponds to the type of log source.

International Classification:

G06F015/173

US Classification:

709/226000

Abstract:

A method and system for managing workloads in an autonomic computer system based on feedback and feed-forward performance information. The method establishes a performance objective for the system, determines a measure of instantaneous demand in the system, continuously tracks the objective with respect to the measure, forecast a future demand based on an autoregressive time series of the system, and adjusts the control parameters of the system to meet the objective. The performance objective is associated with a confidence level and typically includes a desired system response time. The tracking step includes obtaining performance data on the system and storing the performance data in a persistent data store. The demand forecasting uses a Spectral Forecasting procedure to forecast a future workload from a present workload.

International Classification:

G06F 17/30

US Classification:

707200000

Abstract:

A mechanism is provided that aggregates data in a way that permits data to be deleted efficiently, while minimizing the overhead necessary to support bulk deletion of data. A request is received for automatic deletion of segments in a container and a waterline is determined for the container. A determination is made if at least one segment in the container falls below the waterline. Finally, in response to one segment falling below the waterline, the segment from the container is deleted. Each object has an associated creation time, initial retention value, and retention decay curve (also known as a retention curve). At any point, based on these values and the current time, the object's current retention value may be computed. The container system continually maintains a time-varying waterline: at any point, objects with a retention value below the waterline may be deleted.
