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.

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.

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.

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.
