A method, system, and computer usable program product for remote device location identification are provided in the illustrative embodiments. A command to identify a remote device is received, at the remote device in a data processing environment. The command is included in a predetermined communication directed to the remote device. A determination is made whether the command is supported at the remote device. The remote device is identified by transmitting an identification of a location associated with the remote device.

According to one aspect of the present disclosure, a method and technique for dynamic reconfiguration of network devices for outage prediction is disclosed. The method includes: aggregating a plurality of network devices to form an input/output (I/O) link bundle; identifying a quality of service level of data throughput needed by at least one workload utilizing the I/O link bundle; monitoring a parameter of each of the network devices of the I/O link bundle; determining whether the monitored parameter indicates a predicted data throughout quality of service level decrease by a network device being utilized by the workload below the quality of service level for the workload; and responsive to determining that the monitored parameter indicates a predicted quality of service level decrease by the respective network device, dynamically reconfiguring the link bundle to maintain the quality of service level for the workload utilizing the I/O link bundle.

A technique for managing pinned memory in a data processing system includes determining whether a first loadable module is completely utilizing pinned memory assigned to the first loadable module. In response to determining the first loadable module is not completely utilizing the pinned memory assigned to the first loadable module, the pinned memory that is not being utilized by the first loadable module is converted to kernel lock memory. In response to a second loadable module requesting pinned memory and non-kernel lock memory not being available to meet the request, one or more pages of the kernel lock memory are assigned to the second loadable module. In response to the second loadable module requesting the pinned memory and the non-kernel lock memory being available to meet the request, one or more pages of the non-kernel lock memory are assigned to the second loadable module.

A network device can implement configurable socket aggregation to enable segmentation offload in the network device. In one embodiment, it is determined, at the network device, to create a network socket for an application of the network device to initiate a network connection for the application. Socket aggregation parameters are determined for the network socket associated with the application. The network socket is defined based, at least in part, on the socket aggregation parameters. A plurality of packets received from the application associated with the network socket are aggregated. It is determined, based on said aggregating the plurality of packets, whether at least one aggregation limit associated with the socket aggregation parameters is reached. An aggregate packet is provided to a network adapter of the network device to perform segmentation offload in response to said determining that at least one aggregation limit associated with the socket aggregation parameters is reached.
