Abstract: A port processor to receive a read command in a target port. In response, use the target to process a data transfer that includes use of memory for the read transfer allocated by a storage array controller prior to receipt of the read command by the target port or while processing the data transfer and selectively mark such memory as repurposable. The port processor to receive a write command in the target port. In response to receipt of the write command, use the target to process a data transfer for the initiator associated with the write operation, wherein the process includes use of memory that the storage array controller pre-allocated or allocated based on receipt of the read command by the target port for the transfer to the storage array controller and marked as repurposable.

Abstract: A technique includes receiving a command in a target port, where the command is provided by an initiator and is associated with a write operation. The technique includes, in response to the command, using the target to process a data transfer for the initiator associated with the write operation. The processing includes, based on a characteristic of the command, selectively using memory for the transfer pre-allocated by a storage array controller prior to receipt of the command by the target port or requesting an allocation of memory for the transfer from the storage array controller.

Abstract: Techniques for saving session information when transitioning a port to a low power state are provided. An indication of an intent to transition a port to a low power state is provided. Session information related to the port is saved. The port is transitioned to the low power state.

Abstract: Techniques for loading device drivers are provided. A configuration space may contain a device identifier. The configuration space may be modified by replacing the device identifier with a pseudo device identifier. In one aspect the pseudo device identifier may be passed to a virtual machine. In another aspect, the pseudo device identifier may be used to load a driver.

Abstract: Controlling power consumption of aggregated I/O ports. At least some of the illustrative embodiments are methods that include: aggregating a plurality of input/output (I/O) ports; and controlling power consumption in the computer system. Controlling the power consumption includes: sending a command from a power policy management program to an aggregation software executing in the computer system, the aggregation software implements the aggregating; and changing a power consumption mode of at least one of the I/O ports responsive to the command.

Abstract: When a data packet is received in one protocol layer, packet processing information is generated for the data packet and a descriptor for the packet processing information is generated. The packet processing information, the descriptor and the data packet are associated with each other and conveyed to a second protocol layer.
