  • Patent number: 10050901
    Abstract: There is disclosed herein, by way of example, an enterprise server computing platform configured to provide stateless computing, wherein each node has no set configuration, including for example, MAC addresses, UUIDs, firmware, and BIOS by way of non-limiting example. Certain devices or peripherals may be considered “out-of-band,” meaning that they are discoverable and configurable in standby power by a baseboard management controller (BMC) without need for an OS. Certain other peripherals are considered “in-band,” meaning that they may need an OS for discovery and configuration. According to one or more example embodiments of this Specification, a system and method are disclosed for automatically discovering and configuring out-of-band devices on a server. Out-of-band devices may then be disabled, and the server is booted with minimal resources and a bootstrap OS to discover and configure in-band devices.

  • Patent number: 9712455
    Abstract: Presented herein are techniques for resolving VxAN (VSANs and VLANs) networking connectivity, prior to server or domain migration. When UCS domains receive a workload or service profile from a UCS Central Controller, required VLANs/VSANs are checked for deployment for that UCS domain in Fabric Interconnects, and once VLANs/VSANs are successfully confirmed, the workload is deployed into one of the compute servers in that domain.

  • Patent number: 9647933
    Abstract: A method includes assigning a port identifier to a first port on a node and communicating data on a first path between the first port and a logical unit on an active/passive storage array. The port identifier is registered in a persistent reservation scheme for the logical unit. The method also includes detecting a failure of the first path, de-assigning the port identifier from the first port, assigning the port identifier to a second port on the first node, and resuming communications between the node and the logical unit. One implementation of a system includes a first port configured to communicate with a storage device, a second port configured to communicate with the storage device, and an identifier management block. The identifier management block executes a failover with N_Port ID Virtualization commands that transfer a world wide port name from the first port to the second port.

  • Patent number: 9461887
    Abstract: Techniques are provided herein for optimizing boot order for devices in a data center environment. These techniques may be embodied as a method, apparatus and instructions in a computer-readable storage media to perform the method. A computing apparatus having connectivity to a network receives instructions from a management device in the network. The instructions comprise attributes that are associated with boot devices hosted by the computing apparatus. The attributes are analyzed to determine a priority order for the boot devices. One or more boot devices hosted by the computing apparatus is removed from an initialization process when the one or more boot devices do not match the attributes in the instructions. The remaining boot devices, other than the one or more boot device removed from the initialization process, are initialized in accordance with the priority order.

  • Patent number: 8762342
    Abstract: A method for inserting a validated time-image on a primary CDP subsystem in a continuous data protection and replication (CDP/R) subsystem. In one embodiment, the method includes processing data of RI1 at a secondary system in accordance with a recovery process, wherein RI1 is a first image of a replication of a data object. First data is generated in response to processing the data of RI1 in accordance with the recovery process, wherein the first data relates to processing the data of RI1 in accordance with the recovery process. Once the first data is generated, a copy of the first data is transmitted to a primary system that stores the data object.

  • Publication number: 20140101424
    Abstract: Cooperative boot techniques enable sharing of information in an enterprise computing system so as to optimize performance of the system. For example, in an enterprise computing system comprising a management server, one or more server computers, and a storage subsystem, the management server monitors the one or more server computers for a notification that a server computer has started boot operations. The management server determines that a first server computer has started boot operation, and notifies the storage subsystem that a boot-data request is forthcoming from the first server computer. The storage subsystem is notified that the first server computer has started boot operations before the first server computer has completed boot operations so that that the storage subsystem can prepare data likely to be requested in the boot-data request.

  • Patent number: 8694538
    Abstract: A method and apparatus for logging write requests to a storage volume in a network data switch is described. In one example, a switch component in a switch receives a write request from a host server. The write request is associated with a destination in the storage volume. A logging element is identified that is associated with the destination of the write request. The logging element may be a switch component in the switch (e.g., a virtualization card), or may be dedicated logging circuitry in the switch. The identified logging element then logs a write intent for the destination in a log.

  • Patent number: 8401997
    Abstract: Applications executing on various nodes in a distributed storage environment may write data to primary storage and may also replicate the data to secondary storage via a replication target. An interval coordinator may coordinate the periodic saving of checkpoints or snapshots of the replicated data. The interval coordinator may determine the length of consistency intervals between the saving of each of the checkpoints. Writes to the replication target from each of the nodes may be associated with the current consistency interval and, in some embodiments, with a unique per-node sequence number. When transitioning between consistency intervals, each node may be configured to temporarily suspend completion of the writes and to send the replication target a consistency interval marker indicating that the node has completed all writes for the current consistency interval.
