摘要： A command is received, at a network storage driver, from an operating system storage stack, wherein the command is for communication with a target storage device over a connection across a network. The command is selectively executed, a plurality of times over the connection, for communicating with the target storage device, in response to a determination that the command failed to successfully communicate with the target storage device within a threshold period of time.

摘要： Provided are techniques for static load balancing. For each data path in a network adapter team, a load balancing value is computed. A maximum value of the computed load balancing values is determined. A data path with the maximum value is selected for use in routing data. Also provided are techniques for dynamic load balancing in which, when a load balancing share of a data path is less than an actual load balancing share, the load balancing share of the data path is adjusted. Furthermore, provided are techniques for failover processing in which a command is routed through a second network adapter in response to determining that the command may not be routed through a first network adaptor.

摘要： Provided are techniques for static load balancing. For each data path in a network adapter team, a load balancing value is computed. A maximum value of the computed load balancing values is determined. A data path with the maximum value is selected for use in routing data. Also provided are techniques for dynamic load balancing. An actual load balancing share is computed for each data path in a network adapter team. For each data path, it is determined whether a load balancing share for the data path is less than the actual load balancing share for the data path and when the load balancing share is less than the actual load balancing share, the load balancing share of the data path is adjusted. Furthermore, provided are techniques for failover processing. It is determined whether a command may be routed through a first network adapter. The command is routed through the first network adapter in response to determining that the command may be routed through the first network adapter. The command is routed through a second network adapter in response to determining that the command may not be routed through the first network adapter.

摘要： A network storage driver requests a connection from an offload application, wherein the offload application interfaces with a first network stack implemented in an operating system and a second network stack implemented in a hardware device. The connection is received from the offload application, wherein the received connection is an offloaded connection and is reserved for the network storage driver. Data is communicated over the offloaded connection through the hardware device.

摘要： An SAS RAID adapter comprises an input-output processor (IOP) and at least two SAS input-output controllers (IOCs). Wherein SAS links coupled to each of the IOCs form “virtual ports” in order to increase performance and maintain availability. The virtual ports across the at least two IOCs have wide port SAS link capability so as to provide performance enhancements similar to a standard SAS wide port. Even if a single IOC failure occurs, downshifting to N/2 links is provided with degraded aggregated bandwidth (data throughput) instead of a failover and/or system shutdown.
