摘要： A computer-implemented method, according to one embodiment, includes: splitting received information between two controllers of a system in a normal operating mode, the received information including data and metadata; storing the metadata in resilient storage in response to a first of the controllers entering a failed state; updating the first controller with information received while the first controller was in the failed state, the first controller being updated in response to the first controller being repaired; and returning the system to the normal operating mode in response to the first controller being updated. Storing the metadata in resilient storage includes: saving snapshots of the metadata in the resilient storage, and saving changes to the metadata which occur between the snapshots. The changes to the metadata are saved in a log structured array. Moreover, the two controllers store the received information in a specified system memory location.

摘要： A processor initiates an execution of a network driver in a first node comprising a master node of a plurality of nodes in a switchless network. The network driver configures the plurality of nodes and service level in the switchless network by transmitting management datagrams from the master node, wherein the management datagrams include an attribute that allows the management datagrams to be propagated among the plurality of nodes of the switchless network without being terminated at host channel adapters of the plurality of nodes.

摘要： A method, computer program product and computer system achieves full-mesh connectivity between any two domains in a multi-domain computing environment such as an Infiniband or Converged Ethernet environment. A connection between two domains is established using a single connection management identifier, and private payloads in connection management datagrams, to drive full-duplex connectivity over a pair of half-duplex connections. The half-duplex connections are established using one connection request, and one connection ID object. A connection management object interfaces between the two connected domains. The connection management object handles communications across the half-duplex connections while the connected applications operate as if they are communicating over a full-duplex connection.

摘要： Methods, computing systems and computer program products implement embodiments of the present invention that include initializing, by a hypervisor executing on a processor, first and second virtual machines. A first software application configured to provide a service is executed on the first virtual machine, and a logical data connection is established between the first and the second virtual machines. Examples of the logical connection include physical and virtual serial connections, and physical and virtual data networking connections. A second software application configured to enable remote monitoring of the first software application via the logical data connection is executed on the second virtual machine. In some embodiments, the second software application can remotely monitor the first software application via an interface such as a command line interface, a graphical user interface and an application programming interface.

摘要： Various embodiments for data management in a storage grid, by a processor device, are provided. In one embodiment, a method comprises directing data Input/Output (I/O) operations from a host to an owning node according to a Logical Block Address (LBA) without a static assignment of ownership, notwithstanding any relationship between the host and the storage grid.

摘要： ID management for a network attached storage system using layered ID mapping virtualization. When a connection request is received at a NAS server, it is determined whether the request is for a new user, and if so, user IDs are created for the new user. External user ID and filesystem user ID are mapped to the internal user ID, and user ID is verified at the NAS server kernel on subsequent logins with an external database. The user IDs are remapped for the changed user account, and updated mappings are transmitted from the NAS server to one or more NAS server kernel repositories.

摘要： A controller-implemented method, according to one embodiment, includes: receiving, by a first controller, data. Metadata associated with the data is stored, by the first controller, in a specified system memory location. Second metadata received from a second controller is also stored, by the first controller, in the specified system memory location, thereby creating combined metadata. In response to the second controller entering a failed state: snapshots of the combined metadata are stored, by the first controller, to resilient storage at a predefined interval. Moreover, additional data continues to be received by the first controller. Metadata associated with the additional data is stored, by the first controller, in the specified system memory location, while changes to the metadata which occur between the snapshots of the combined metadata are also stored by the first controller. According to some approaches, the changes to the metadata are stored in a log structured array.

摘要： Methods, computing systems and computer program products implement embodiments of the present invention that include detecting, on a communications network in a computing facility including a first computer coupled to a second computer via the communications network, an input/output (I/O) request conveyed from the first computer to the second computer. Subsequent to detecting the I/O request, data traffic resulting from the second computer processing the I/O request is identified on the communications network, and network statistics are collected based on the I/O request and the data traffic. Upon detecting a performance degradation of the computing facility, the performance degradation greater than a predetermined amount, heuristics can be applied to the collected network statistics, to identify a cause of the performance degradation and to identify a remedy to the detected performance degradation. In some embodiments, the identified cause and the identified remedy can be presented to a user on a display.

摘要： A connection management message that uses a proxy attribute is received, wherein the connection management message includes information on a first proxy queue pair and a second proxy queue pair, wherein the first proxy queue pair provides communication between a proxy node and an initiator node in a switchless network, and wherein the second proxy queue pair provides communication between the proxy node and a target node in the switchless network. The connection management message that uses the proxy attribute, channels datagrams received from the initiator node to the target node in the switchless network.
