20140279320 | ALLOCATING AND PRICING VIRTUAL RESOURCES - A method and apparatus for allocating and pricing virtual resources is provided. According to one aspect, pricing information is obtained for a plurality of virtual resources offered by a plurality of providers. A set of selected virtual resources is determined for a first customer. An expected quantity is determined for at least one virtual resource for the first customer. A fixed charge is determined based on the pricing information, the set of selected virtual resources and at least one expected quantity. At least one unit rate is determined for at least one virtual resource based on the pricing information. The first customer is provided access to the set of selected virtual resources during a billing period, wherein the fixed charge is billed for the billing period. An overflow charge, if any, is determined the at least one unit rate and an actual usage during the billing period. | 09-18-2014 |
20140281308 | STORAGE UNIT SELECTION FOR VIRTUALIZED STORAGE UNITS - Performance information for storage units located at a virtual data center is determined by executing storage administrator logic whose execution is controlled by a management entity different than the virtual data center provider. Performance expectations are automatically determined based on the determined performance information. In response to determining that a particular storage unit is incompatible with performance expectations applicable to the particular storage unit, embodiments cause a reduction in utilization of the particular storage unit. Based on determined performance information, another embodiment determines that a performance pattern indicating a physical co-location of a first storage unit and a second storage unit has occurred. In response to determining that the performance pattern indicating a physical co-location of a first storage unit and a second storage unit has occurred, the embodiment disables use of a selected storage unit of the first storage unit or the second storage unit for at least a particular purpose. | 09-18-2014 |
20140282521 | EXPANSION OF SERVICES FOR A VIRTUAL DATA CENTER GUEST - One or more services for enhancing guest utilization of a virtual machine and other VDC resources may be provided at the intermediary manager. In an embodiment, the intermediary manager intercepts a hypercall from a guest operating system that is separate from the intermediary manager. The intermediary manager determines that a particular intermediary service is associated with the hypercall and causes execution of service instructions associated with the particular intermediary service. The intermediary manager and guest operating systems may operate within a virtual machine hosted by a host machine and managed by a hypervisor. Embodiments may be useful in any of a virtualized enterprise computer system; a virtual machine infrastructure in a private data center; computing, storage or networking resources in a private cloud; computing, storage or networking resources of cloud service provider; and a hybrid cloud computing environment. | 09-18-2014 |
20140282824 | AUTOMATIC TUNING OF VIRTUAL DATA CENTER RESOURCE UTILIZATION POLICIES - A computer-implemented process receives a request to utilize one or more virtual data center (VDC) resources at a virtual data center and determines a particular service level applicable to request. Based on the particular service level and mapping information that indicates associations between VDC resource utilization policies and service levels, the process determines a particular VDC resource utilization policy corresponding to the request and causes completion of the request according to the particular VDC resource utilization policy. Another process determines that a resource utilization performance is incompatible with a requested service level and selects a new resource utilization based in part on the resource utilization performance information and mapping information. The process causes data distributed according to a prior resource utilization policy to be distributed according to the new resource utilization policy in one or more resources at a virtual data center. | 09-18-2014 |

20100125598 | ARCHITECTURE FOR SUPPORTING SPARSE VOLUMES - An architecture, including a file-level protocol, for supporting sparse volumes on a storage system is provided. The file-level protocol provides coherency checking for use in retrieving data stored on a backing store remote from a storage system. | 05-20-2010 |
20100325377 | SYSTEM AND METHOD FOR RESTORING DATA ON DEMAND FOR INSTANT VOLUME RESTORATION - A technique is disclosed for restoring data of sparse volumes, where one or more block pointers within the file system structure are marked as ABSENT, and fetching the appropriate data from an alternate location on demand. Client data access requests to the local storage system initiate a restoration of the data from a backing store as required. A demand generator can also be used to restore the data as a background process by walking through the sparse volume and restoring the data of absent blocks. A pump module is also disclosed to regulate the access of the demand generator. Once all the data has been restored, the volume contains all data locally, and is no longer a sparse volume. | 12-23-2010 |
20130304844 | SYSTEM AND METHOD FOR CACHING NETWORK FILE SYSTEMS - A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that “virtualizes” a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server. | 11-14-2013 |
