Appl. No.:

13/325332

Inventors:

KEVIN J. CAWLFIELD - AUSTIN TX, US
CHANG W. CHEN - AUSTIN TX, US
MITCHELL P. HARDING - AUSTIN TX, US

Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION - ARMONK NY

International Classification:

G06F 9/455

US Classification:

718 1

Abstract:

A hypervisor negotiates to reserve at least one available local resource in a host system that meets a performance parameter for at least one resource specified in a reservation request by a particular logical partition from among one or more logical partitions of virtualized pools of resources managed by the hypervisor in the host system, wherein the at least one performance parameter is specified by a particular application initiating the reservation request. The hypervisor, responsive to determining that the at least one available resource is not available in the host system, negotiates for offers to migrate the particular logical partition to at least one other host system comprising at least one available remote resource that meets the performance parameter, wherein the at least one other host system is managed by at least one other hypervisor that manages one or more other logical partitions of virtualized pools of resources.

International Classification:

G06F 9/455

US Classification:

718 1

Abstract:

Responsive to a hypervisor determining that insufficient local resources are available for reservation to meet a performance parameter for at least one resource specified in a reservation request for a particular logical partition managed by the hypervisor in a host system, the hypervisor identifies another logical partition managed by the hypervisor in the host system that is assigned at the least one resource meeting the performance parameter specified in the reservation request. The hypervisor estimates a first cost of migrating the particular logical partition and a second cost of migrating the another logical partition to at least one other host system communicatively connected in a peer-to-peer network based on at least one previously recorded cost stored by the host system of migrating a previous logical partition to the at least one other host system.

International Classification:

H04L 9/32

US Classification:

726027000

Abstract:

A method, apparatus, and computer program product are disclosed for controlling copying and playback of digital data. Digital data is selected that is to be stored using a portable digital storage medium. Data that is stored using the medium is capable of being accessed only when the medium is inserted into a drive that can be accessed by a data processing system. During manufacturing of the medium: a unique identifier is stored within the medium where the unique identifier identifies only that one particular medium, a copy of the unique identifier is also stored in a tag that is affixed to a surface of the medium, a public key/private key pair is selected for encrypting and decrypting data where data that has been encrypted using the private key of the pair is capable of being decrypted using only the public key of the pair, the public key of the pair is stored within the tag, the digital data is encrypted using the private key of the pair, and the encrypted data is stored using the medium.
