126 results about "System virtualization" patented technology

Operating system virtualization (OS virtualization) is a server virtualization technology that involves tailoring a standard operating system so that it can run different applications handled by multiple users on a single computer at a time. The operating systems do not interfere with each other even though they are on the same computer.

Network consolidation for virtualized servers

Techniques are disclosed for virtualized server kernel and virtual networks consolidation. The network consolidation allows a data center to migrate from an infrastructure that uses multiple dedicated gigabit Ethernet Network Adapters to manage system virtualization and migration to an infrastructure using consolidated, redundant, 10 gigabit Ethernet adapters. Different priority classes may be defined for different classes of network traffic such as hypervisor management traffic, inter-host virtual machine migration traffic, virtual machine production traffic, virtualized switching control plane traffic, etc. Further, an enhanced transmission standard may be used to specify a minimum bandwidth guarantee for certain traffic classes. Thus, the hypervisor management and inter-host virtual machine migration traffic may be transmitted, even the presence of congestion.

Data backup system and method for virtual infrastructure

Systems for backing up the data of an IT system by utilizing server or storage virtualization technology to create and move logical IT infrastructures dynamically. A virtualized IT system provides a server resource pool and a storage resource pool composed from multiple physical devices either within a datacenter or a globally located plurality of datacenters. The virtual server and the storage volume provisioned from those pools will be paired to form the virtual infrastructure. In other words, the virtual infrastructure becomes a logical IT environment build with the required computing and storage resources needed in order to execute specific applications. The virtual infrastructure can also be migrated within / among datacenter sites.

Non-disruptive data mobility using virtual storage area networks with split-path virtualization

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.

Method for intensively storing and backing up data based on operating system virtualization theory

The invention relates to a method for intensively storing and backing up data based on an operating system virtualization theory in the technical field of computer application. The method is characterized by comprising the following steps of: constructing one to a plurality of virtual isolation environments on a host operating system of a physical host machine, wherein each virtual isolation environment has a use mode which is totally the same as the use mode of the host operating system; and completely isolating data produced in the virtual isolation environment from data produced by the host operating system, and storing the data to different physical storage positions respectively. By storing an application program relative to a working service of a user into the virtual isolation environment and running the application program, and redirecting the physical storage position to a storage server in a network through a common internet file system (CIFS) or internet small computer system interface (iSCSI) protocol, a manager only needs to back up the data on the storage server at a time when the data of all client hosts are needed to be backed up, so the working efficiency is improved greatly; meanwhile, only the data relative to the working service is backed up, so the backup storage space is saved and useless data restoration is avoided.

A method of implementing virtualization involves an improved approach to virtual memory management. An operating system includes a kernel, a resource control framework, a virtual memory subsystem, and a virtualization subsystem. The virtualization subsystem is capable of creating separate environments that logically isolate applications from each other. The virtual memory subsystem utilizes swap space to manage a backing store for anonymous memory. The separate environments share physical resources including swap space. When a separate environment is configured, properties are defined. Configuring a separate environment may include specifying a swap cap that specifies a maximum amount of swap space usable by the separate environment. The resource control framework includes a swap cap resource control. The swap cap resource control is enforced by the kernel such that during operation of the separate environment, the kernel enforces the swap cap specified when the separate environment was configured.

Method and system for virtualizing metadata between disparate systems

A non-programmatic method for virtualizing the metadata of external systems at a front-end system is disclosed. The front-end system is provided with programmatic hooks that enable the external capture of its search for metadata and its commands to retrieve properties comprising selected metadata. When an end user of the front-end system requests to retrieve properties comprising selected metadata, typically through the use of a client device, an integrating system captures the search for metadata and provides a list of metadata both native to the front-end system and virtualized from disparate external systems.The end user selects metadata in order to retrieve properties comprising the metadata. The integrating system captures the front-end system's command to retrieve the metadata. The integrating system converts the metadata request from the format of the front-end system to the format of the external system whose metadata was selected. The external system returns the properties comprising the requested metadata. The integrating system receives the resultant properties comprising the metadata, converts it to the format of the front-end system, and passes the resultant converted properties comprising the metadata to the front-end system for presentation to the end user.
