Methods and systems for establishing a cloud bridge between two virtual storage resources and for transmitting data from one first virtual storage resource to the other virtual storage resource. The system can include a first virtual storage resource or cloud, and a storage delivery management service that executes on a computer and within the first virtual storage resource. The storage delivery management service can receive user credentials of a user that identify a storage adapter. Upon receiving the user credentials, the storage delivery management service can invoke the storage adapter which executes an interface that identifies a second virtual storage resource and includes an interface translation file. The storage delivery management service accesses the second virtual storage resource and establishes a cloud bridge with the second virtual storage resource using information obtained from the second virtual storage resource and information translated by the storage adapter using the interface translation file.

A system for automated management of virtual resources in a cloud computing environment includes a host computing device communication component and a storage system communication component. The storage system communication component is executed by a storage delivery management service, communicates with a storage system adapter in a storage area network to identify a storage system in a storage area network, and directs the automated provisioning of a virtual storage resource on the identified storage system, the storage system providing resources for provisioning the virtual drive. The host computing device communication component receives a request for access by a host computing device to the virtual storage resource, and responds, to the host computing device, with an identification of a network port of the identified storage system and an identification of the provisioned virtual storage resource.

To detect a computer virus in a host file (100), an emulating module (414) emulates the host file (100) in a virtual machine (422) having a virtual memory (426). While emulating the host file (100), the system (400) tracks the host file's access of the virtual memory (426). Responsive to an access in a non-normal address range of the virtual memory (426) by the host file (100), a flag recording module (522) sets a flag. A virus reporting module (526) declares a potential virus based on whether the flag is set.

A system has a virtual overlay infrastructure mapped onto physical resources for processing, storage and network communications, the virtual infrastructure having virtual entities for processing, storage and network communications. Virtual infrastructures of different users share physical resources but are isolated and have their own management entities. An interface between infrastructures allows controlled relaxation of the isolation, using a gateway between virtual nets, or shared virtual storage devices. This can allow businesses to share data or applications, while maintaining control of security.

Methods and apparatus for implementing storage virtualization on a network device of a storage area network are disclosed. A frame or packet is received at a port of the network device. It is then determined that the frame or packet pertains to access of a virtual storage location of a virtual storage unit representing one or more physical storage locations on one or more physical storage units of the storage area network. A virtual-physical mapping between the one or more physical storage locations and the virtual storage location is then obtained. A new or modified frame or packet is then sent to an initiator or a target specified by the virtual-physical mapping.

A solid-state disk (SSD) has a smart storage switch with a smart storage transaction manager that re-orders host commands for accessing downstream single-chip flash-memory devices. Each single-chip flash-memory device has a lower-level controller that converts logical block addresses (LBA) to physical block addresses (PBA) that access flash memory blocks in the single-chip flash-memory device. Wear-leveling and bad block remapping are preformed by each single-chip flash-memory device, and at a higher level by a virtual storage processor in the smart storage switch. Virtual storage bridges between the smart storage transaction manager and the single-chip flash-memory devices bridge LBA transactions over LBA buses to the single-chip flash-memory devices. Data striping and interleaving among multiple channels of the single-chip flash-memory device is controlled at a high level by the smart storage transaction manager, while further interleaving and remapping may be performed within each single-chip flash-memory device.

Methods, apparatus and computer programs have been provided for mitigating a problem of non-optimal recovery from storage device failures. A method involves determining a required write performance for rebuilding data of a failed device, based at least partly on the potential read performance of storage devices in a data rebuild; and allocating a virtual storage area within available storage, which allocation of virtual storage is based at least partly on the required write performance. Data is rebuilt by writing to the allocated virtual storage area, and data recovery is completed by migrating this rebuilt data to at least one data storage device such as a spare physical storage device within the array.

In one embodiment, a system is disclosed for collaborating information over a network. The system may include a storage device and one or more processors. The processor(s) may maintain documents in the storage device and publish content links to the documents in a workspace rendered by a collaboration platform. The processor(s) may provide content to the collaboration platform in response to a content link selection by a reviewer and receive the reviewer's changes, with the collaboration platform temporarily storing the document in a virtual memory for rendering to the reviewer and deleting it after the communication session ends. The processor(s) may synchronize the changes bi-directionally from the workspace with the original document through a collaboration document, such that the original document remains unaltered, and by re-publishing an updated content link to the workspace.

A virtual memory system implementing the invention provides concurrent access to translations for virtual addresses from multiple address spaces. One embodiment of the invention is implemented in a virtual computer system, in which a virtual machine monitor supports a virtual machine. In this embodiment, the invention provides concurrent access to translations for virtual addresses from the respective address spaces of both the virtual machine monitor and the virtual machine. Multiple page tables contain the translations for the multiple address spaces. Information about an operating state of the computer system, as well as an address space identifier, are used to determine whether, and under what circumstances, an attempted memory access is permissible. If the attempted memory access is permissible, the address space identifier is also used to determine which of the multiple page tables contains the translation for the attempted memory access.

A storage object such as a virtual disk drive or a raw logical volume is contained in a UNIX compatible file so that the file containing the storage object can be exported using the NFS or CIFS protocol and shared among UNIX and MS Windows clients or servers. The storage object can be replicated and backed up using conventional file replication and backup facilities without disruption of client access to the storage object. For client access to data of the storage object, a software driver accesses the file containing the storage object. For example, a software driver called a virtual SCSI termination is used to access a file containing a virtual SCSI disk drive. Standard storage services use the iSCSI protocol to access the virtual SCSI termination. An IP replication or snapshot copy facility may access the file containing the virtual SCSI disk drive using a higher-level protocol.

A multi-user file storage service and system enable each user of a pre-subscribed user group to operate an arbitrary client node at an arbitrary geographic location, to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node in communication with the remote file server node via the wide area network. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Illustratively, the integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Thus, all native operating system application programming interfaces operate as if all multi-user applications accessing the files function as if the remote server and client nodes were on the same local area network. Illustratively, an interface is provided for adapting file access one of the client nodes. The interface designates at the client node each accessible file of the group as stored on a virtual storage device. The interface enables access to the designated files in a fashion which is indistinguishable, by users of, and applications executing at, the client node, with access to one or more files stored on a physical storage device that is locally present at the client node. Illustratively, an encrypted key is transferred from the remote file server node to one of the client nodes via a secure channel. The key is encrypted using an encryption function not known locally at the remote file server node. The transferred key is decrypted at the client node. The key is used at the client node to decrypt information of the files downloaded from the remote file server node or to encrypt information of the files prior to uploading for storage at the remote file server node. Access control to a particular one of the files of the group can be delegated to an access control node.

A virtual-machine-based system provides a mechanism for a virtual machine monitor (VMM) to process a hypercall received from an application running in the virtual machine (VM). A hypercall interface causes the virtual memory pages, needed by the VMM to process the hypercall, to be available to the VMM. In one embodiment, when virtual memory pages needed by the VMM to process the hypercall are not available to the VMM, the application is caused to access the needed pages, in response to which the required virtual memory becomes available to the VMM.

A system for write forwarding in a storage environment employing distributed virtualization includes a first and a second storage server providing access to a first and a second physical storage device, respectively, a virtual device server and a virtual device client. The virtual device server may be configured to aggregate storage in the first and second physical storage device into a virtual storage device and make the virtual storage device accessible to the virtual device client for I / O operations. An update requested by the virtual device client may require a first physical write operation at the first physical storage device and a second physical write operation at the second physical device. The virtual device client may be configured to send an update request to the first storage server, rather than to both the first and the second storage servers. The first storage server may respond to the update request by starting the first physical write operation, and forwarding a request for the second physical write operation to the second storage server.

Systems, methods, and computer program products are provided for instant recovery of a virtual machine (VM) from a compressed image level backup without fully extracting the image level backup file's contents to production storage. The method receives restore parameters and initializes a virtual storage. The method attaches the virtual storage to a hypervisor configured to launch a recovered VM. The method stores virtual disk data changes inflicted by a running operating system (OS), applications, and users in a changes storage. The method provides the ability to migrate the actual VM disk state (taking into account changed disk data blocks accumulated in changes storage) so as to prevent data loss resulting from the VM running during the recovery and accessing virtual storage, to production storage without downtime. In embodiments, the method displays receives restore parameters in an interactive interface and delivers the recovery results via an automated message, such as an email message.

A virtual file system and method. The system architecture enables a plurality of underlying file systems running on various file servers to be “virtualized” into one or more “virtual volumes” that appear as a local file system to clients that access the virtual volumes. The system also enables the storage spaces of the underlying file systems to be aggregated into a single virtual storage space, which can be dynamically scaled by adding or removing file servers without taking any of the file systems offline and in a manner transparent to the clients. This functionality is enabled through a software “virtualization” filter on the client that intercepts file system requests and a virtual file system driver on each file server. The system also provides for load balancing file accesses by distributing files across the various file servers in the system, through migration of data files between servers.

At least one of the virtual storage units comprises a cache unit. A cache command module exchanges cache management information for the at least one cache unit with one or more cache clients over the cache interface. A cache management module manages the at least one cache unit based on the cache management information exchanged with the one or more cache clients.

In one embodiment, a backup application transmits a remote request to a virtual machine that includes an application to be backed up. The request solicits metadata from the application that describes a structure of the data stored by the application on the virtual storage devices of the virtual machine. Using the metadata, the backup application may identify objects within the virtual machine (e.g. individual files, individual messages, database records or tables, etc.). Accordingly, a granular restore of data to the virtual machine may be possible without installing backup software within the virtual machine.
