Publication number: 20150052250Abstract: Disclosed is a novel system and method for managing requests for an additional virtual machine. The method begins with operating at least one virtual machine accessing at least one computer resource associated with at least one physical machine within a computing cluster. One or more non-deterministic virtual machine requests for the computer resource are received. An over-utilization of the computer resource as a probability distribution function is modeled. In one example, the probability distribution function is a Beta distribution function to represent a one of a plurality of probability distribution functions. Next, an additional virtual machine on the physical machine associated with the computer resource is added in response to a probability of a utilization of the computer resource being greater than a probalistic bound on the over-utilization of the computer resource. Otherwise, the additional virtual machine is not added.Type: ApplicationFiled: August 14, 2013Publication date: February 19, 2015Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yurdaer N.

Patent number: 8560779Abstract: A method and structure for processing an application program on a computer. In a memory of the computer executing the application, an in-memory cache structure is provided for normally temporarily storing data produced in the processing. An in-memory storage outside the in-memory cache structure is provided in the memory, for by-passing the in-memory cache structure for temporarily storing data under a predetermined condition. A sensor detects an amount of usage of the in-memory cache structure used to store data during the processing. When it is detected that the amount of usage exceeds the predetermined threshold, the processing is controlled so that the data produced in the processing is stored in the in-memory storage rather than in the in-memory cache structure.Type: GrantFiled: May 20, 2011Date of Patent: October 15, 2013Assignee: International Business Machines CorporationInventors: Claris Castillo, Michael J.

Patent number: 8140812Abstract: Techniques for placement of a virtual machine in a computing system. A first request is sent from a pool management subsystem to a placement subsystem. The first request includes specification of available storage capacities of storage systems in a computer network. The placement subsystem automatically determines a target storage system based, at least in part, on the available storage capacities. An identification of the target storage system is received at the pool management subsystem. At least one disk image of the virtual machine is written to the target storage system. Then, a second request is sent to the placement subsystem. The placement subsystem automatically determines a target computer. The latter determination is based, at least in part, on connectivity between the target computer and the target storage system. The virtual machine is installed at the target computer. The techniques facilitate live migration of virtual machines placed thereby.Type: GrantFiled: July 1, 2009Date of Patent: March 20, 2012Assignee: International Business Machines CorporationInventors: Diana J.
