One embodiment of the present invention provides a system that facilitates end-to-end virtualization. During operation, a network interface residing on an end host sets up a tunnel. The network interface then encapsulates a packet destined to a virtual machine based on a tunneling protocol. By establishing a tunnel that allows a source host to address a remote virtual machine, embodiments of the present invention facilitate end-to-end virtualization.

Various embodiments virtualize data across heterogeneous formats. In one embodiment, a plurality of heterogeneous data sources is received as input. A local schema graph including a set of attribute nodes and a set of type nodes is generated for each of the plurality of heterogeneous data sources. A global schema graph is generated based on each local schema graph that has been generated. The global schema graph comprises each of the local schema graphs and at least one edge between at least one of two or more attributes nodes and two or more type nodes from different local schema graphs. The edge indicates a relationship between the data sources represented by the different local schema graphs comprising the two or more attributes nodes based on a computed similarity between at least one value associated with each of the two or more attributes nodes.

A system including a storage processing device with an input/output module. The input/output module has port processors to receive and transmit network traffic. The input/output module also has a switch connecting the port processors. Each port processor categorizes the network traffic as fast path network traffic or control path network traffic. The switch routes fast path network traffic from an ingress port processor to a specified egress port processor. The storage processing device also includes a control module to process the control path network traffic received from the ingress port processor. The control module routes processed control path network traffic to the switch for routing to a defined egress port processor. The control module is connected to the input/output module. The input/output module and the control module are configured to interactively support data virtualization, data migration, data journaling, and snapshotting. The distributed control and fast path processors achieve scaling of storage network software. The storage processors provide line-speed processing of storage data using a rich set of storage-optimized hardware acceleration engines. The multi-protocol switching fabric provides a low-latency, protocol-neutral interconnect that integrally links all components with any-to-any non-blocking throughput.

An apparatus and process for relabelling and redirecting at least some of the read transaction data frames and the write transaction write data and transfer ready frames in a network so as to bypass a storage manager and pass directly between the client and a storage device via a switch. This eliminates the storage manager as a bottleneck. Some embodiments redirect every read and write transaction, and others redirect only large transactions, or only ones not stored in cache or when latency gets too high. Redirection is accomplished by transmission from the storage manager to a switch redirection commands that contain old and new address data. When a frame to be redirected comes in, its address is compared to the old address data. If there is a match, the new address data is substituted and the frame is passed to a conventional routing process to be routed so as to bypass the storage manager.

The present invention is generally directed to a system and method for virtualizing storage in a networked system. In accordance with one aspect of the invention, in a system having an initiator and at least one storage device, an inventive method determines, based upon a SCSI command received by a manager from the initiator, which of the data storage devices are implicated by the SCSI command. The method then forms an iSCSI command that is sent from the manager to each of the implicated storage devices, and receives at the manager an iSCSI response from each of implicated storage devices, after each of the storage devices has completed its implicated data transactions with the initiator. Finally, the method forms a SCSI response that is sent by the manager to the initiator. A corresponding system is also provided.

A method and entities for virtualizing resources by receiving a first virtualization request from a first entity at a virtualization broker in a network of connected entities, wherein the first virtualization request comprises context information associated with the first entity, transmitting a request from the virtualization broker to a virtualization manager for a virtualization server identifier, and receiving a virtualization server identifier from the virtualization manager. A second virtualization request may be transmitted to a virtualization server associated with the virtualization server identifier, and a first response may be received from the virtualization server comprising an indication that a resource has been virtualized. A second response comprising the indication from the virtualization broker may be transmitted to the first entity. The method is applied in the context of the Internet of Things (IoT).

A system includes one or more storage devices and virtualization software configured to aggregate storage in the one or more storage devices into a virtual storage device accessible to a storage consumer. The virtualization software may include a group validation layer comprising a device-independent interface configured to validate a proposed group configuration operation on the one or more storage devices. The device-independent interface may be used to verify that the proposed configuration operation would, if completed, result in a configuration capable of supporting a desired virtualization functionality. The device-independent interface may allow an application to manage the one or more devices as a unit known as a virtual device group.

A computing device hosts a virtual machine executing a guest that issues guest hardware requests by way of any of a plurality of paths. Such paths include a path to non-existent virtual hardware, where an emulator intercepts and processes such guest hardware request with a corresponding actual hardware command; a path to an instantiated operating system, where the instantiated operating system processes each such guest hardware request with a corresponding actual hardware request; and a path to device hardware, where the device hardware directly processes each such guest hardware request.

According to embodiments of the present invention a computer system that is capable of sharing physical devices among several virtual machines (VM) includes hardware assisted logic to allow requests from guest operating systems (guest OS) to circumvent a virtual machine monitor ((VMM) and be processed by the hardware assisted logic.

A variety of indices are used to allow direct access of a physical partition upon identification of a virtual disk address.

A system creates a storage area network (SAN) centric storage virtualization layer in front of storage devices. The system allows data mobility and migration without disruption to the one or more host servers attached to the SAN. Specifically, the host servers are not disrupted when switching I/Os between physical and virtual storage, for example, by taking advantage of WWPN spoofing and Fibre Channel VSAN technology. The use of VSANs effectively allow multiple virtual directors and/or switches to be created within a physical director and/or switches, each with their own separate name server, thereby providing complete isolation from one another. The host-storage pathing information is unchanged as the original physical storage port's WWPNs are spoofed by the virtual storage port. The result is two identical WWPNs within the SAN which is normally disallowed; however, by separating the physical port WWPN into one VSAN and the virtual port WWPN into another, the restriction may be circumvented.

In addition, the present invention provides an additional aspect of ensuring that file names of multi-protocol files are compatible across every protocol.

The illustrative embodiment of the present invention provides a method of inserting a software created virtual interface between the user of a host electronic device and a network storage medium. Data read and write requests are written to the virtual interface. The virtual interface is located on the host electronic device and allocates data to available storage mediums. Recovery and reconfiguration operations on the storage mediums holding stored data are hidden from the user by the virtual interface and may be performed contemporaneously with the user accessing the stored data.

The invention provides a device virtualization system and method based on Linux containers. Virtual device clients and a virtual device server are loaded between Android system HALs and a device subsystem; device operation requests are sent to the virtual device server through the virtual device clients; and then the virtual device server finishes function call in a manufacturer dynamic library, thus realizing agency for the device operations, or constructs device operation results, thus realizing reuse of the device subsystem. According to the device virtualization system and method provided by the invention, through loading the virtual device clients and the virtual device server in multiple Android systems and container management service in a Linux kernel, the agency for the device operations and the reuse of the device subsystem are finished, thus realizing virtualization of the device; a new method different from a traditional device virtualization method is provided; and the reuse of special devices (especially devices without open source code) such as Radios is realized in the multi-Android platform based on a Linux container technique.

The present is a system and method for preserving user account security privileges during a migration or re-direction of data from one network attached storage (“NAS”) system to another. Certain NAS systems authenticate user accounts using Kerberos Delegation Technology. In addition, some NAS systems feature the ability to constrain delegation to certain services. While effective in limiting access and promoting network security, this constrained delegation restricts the ability of a storage virtualization system to migrate or re-direct data to other NAS systems, especially if the other NAS system resides or is identified by a different domain name. The present invention is a system and method for storing user account credentials that work with the former NAS system, and providing a way to translate these credentials to a new NAS system with a new domain, permitting seamless data migration and re-direction across domains.

Applications running in an API-proxy-based emulator are prevented from infecting a PC's hard disk when executing file I/O commands. Such commands are redirected to an I/O redirection engine instead of going directly to the PC's normal operating system where it can potentially harm files in on the hard disk. The redirection engine executes the file I/O command using a private storage area in the hard disk that is not accessible by the PC's normal operating system. If a file that is the subject of a file I/O command from an emulated application is not in the private storage area, a copy is made from the original that is presumed to exist in the public storage area. This copy is then acted on by the command and is stored in the private storage area, which can be described as a controlled, quarantined storage space on the hard disk. In this manner the PC's (or any computing device's) hard disk is defended from potential malware that may originate from applications running in emulated environments.
