Patent number: 9195489Abstract: The invention relates to a mechanism for image deployment in a cloud environment comprising at least two hosts coupled to at least one disk, and at least one virtual machine created in at least one host of the at least two hosts by deploying an additional image to the at least one disk. The method is characterized in that the at least one host for deploying an additional image is selected according to a deployment factor representing a communality relationship between one or more existing base images in the cloud environment and the additional image.Type: GrantFiled: June 13, 2014Date of Patent: November 24, 2015Assignee: International Business Machines CorporationInventors: Dirk Bolte, Herwig Elfering, Thomas Pohl, Martin Troester

Publication number: 20150268973Abstract: Embodiments relate to controlling configuration of a computer system comprising one or more exchangeable components. The exchangeable components comprising identification means to store an identifier. A pair of a private key and a public key are generated for each accepted manufacturer of the exchangeable components and a pair of a private key and a public key for the computer system; assigning an identifier for each exchangeable component available for attachment to the system; receiving configuration data comprising a list of encrypted identity records comprising identifiers of the components together with signatures over the data generated with the private key of the respective component manufacturer for each component expected to be attached to the system; and receiving a configuration record. The configuration data of the expected components from the received configuration record is compared with the configuration data of the components attached to the system.Type: ApplicationFiled: June 4, 2015Publication date: September 24, 2015Applicant: International Business Machines CorporationInventors: Andreas Bieswanger, Dirk Bolte, Carl Mayer, Thomas Pohl, Martin Troester

Patent number: 9081788Abstract: A caching mechanism is provided in a computer server system including at least one host coupled to at least one disk, one or more virtual machines, one or more images of the one or more virtual machines created in a file system of the disk, and a virtual machine manager for assigning hardware resources of the computer server system to the one or more virtual machines. The mechanism provides a masking cache layer between the one or more virtual machines and the virtual machine manager, the masking cache layer including at least one separate entry for every cacheable data block of the file system to be referenced, collects profiling information related to one or more of the cacheable data blocks (58) and stores the profiling information in the masking cache layer and configures the masking cache layer according to the profiling information, or provides a configuration for the masking cache layer.Type: GrantFiled: February 13, 2013Date of Patent: July 14, 2015Assignee: International Business Machines CorporationInventors: Dirk Bolte, Herwig Elfering, Thomas Pohl, Martin Troester

Publication number: 20150088838Abstract: A method of securely deleting data from a data storage device is described. The method includes the steps of receiving a secure delete command to securely delete a file. A data block of the file to securely delete is identified. A pointer to the data block is stored in a deletion buffer. It is then determined whether the secure delete command has a highest priority over other data storage device commands. In response to the secure delete command having the highest priority, the secure delete command to the data block is performed.Type: ApplicationFiled: September 25, 2013Publication date: March 26, 2015Applicant: International Business Machines CorporationInventors: Jakob C. Lang, Angel Nunez Mencias, Thomas Pohl, Martin Troester

Publication number: 20140137113Abstract: Data that includes information about an application is retrieved from a data feed. It is determined that the data from the data feed indicates that the application has been updated. In response to a determination that the data from the data feed indicates that the application has been updated, data descriptive of the application is extracted from the data from the data feed. One or more instructions for installing the application are determined based, at least in part, on the data descriptive of the application. In response to determination of the one or more instructions for installing the application, a first virtual machine skeleton that includes the one or more instructions for installing the application is generated.Type: ApplicationFiled: November 12, 2013Publication date: May 15, 2014Applicant: International Business Machines CorporationInventors: Dirk Bolte, Daniel Ketcham, Thomas Pohl, Martin Strobel, Martin Troester
