  • Resource virtualization switch
    Patent number: 8291148
    Abstract: Methods and apparatus are provided for virtualizing resources including peripheral components and peripheral interfaces. Peripheral component such as hardware accelerators and peripheral interfaces such as port adapters are offloaded from individual servers onto a resource virtualization switch. Multiple servers are connected to the resource virtualization switch over an I/O bus fabric such as PCI Express or PCI-AS. The resource virtualization switch allows efficient access, sharing, management, and allocation of resources.
    Type: Grant
    Filed: April 12, 2012
    Date of Patent: October 16, 2012
    Assignee: Xsigo Systems, Inc.
    Inventors: Shreyas Shah, Subramaniam Vinod, Ramalingam K. Anand, Ashok Krishnamurthi

  • Virtualized shared security engine and creation of a protected zone
    Patent number: 7634650
    Abstract: Methods and apparatus are provided for creating a secure zone having multiple servers connected to a resource virtualization switch through I/O bus interfaces, such as PCI Express or PCI-AS. Servers connected to the resource virtualization switch using I/O bus interfaces share access to one or more virtualized cryptographic accelerators associated with the resource virtualization switch. Applications on a server or system images running on hypervisor inside server can use cryptographic accelerators associated with the resource virtualization switch as though the resources were included in the server itself. Connections between multiple servers and the resource virtualization switch are secure non-broadcast connections. Data provided to a resource virtualization switch can be cryptographically processed using one or more shared and virtualized cryptographic accelerators.
