  • Patent number: 9652182
    Abstract: Disclosed are a system, a method and/or an apparatus of a shareable virtual non-volatile storage device for a server. In one embodiment, the system includes a server, a storage array, a management processor, and a switching fabric. The storage array includes a storage device coupled with a controller associated with a shared driver to receive a data request from the server at a remote location from the storage array through the switch fabric via a communication link to direct the data request to the storage device coupled with it and transmit data to the server through the switch fabric. A virtual storage device is generated in the server to enable the server to share the shared driver in the storage array with other servers through the switch fabric between the server and the storage array. The server distributes the data across the storage devices through the shared driver.

  • Publication number: 20170093998
    Abstract: In one embodiment, a method includes receiving a registration request from an application running on a client system. The registration request includes a messaging token associated with a message-distribution server. In response to the received registration request, the messaging token is registered to a user profile on a social-networking system. A push notification is generated for display at the client system. The push notification and the messaging token are sent to the message-distribution server, where the messaging token identifies the client system to the message-distribution server for delivery of the push notification.
