    • Provided are a method, system, and program for managing transmit throughput for a network controller. In one embodiment, transmit requests from an application may be posted by the device driver to the network controller of the network adapter in a pipeline of transmit requests without waiting for an acknowledgment of the transfer of the accompanying transmit data to the network controller. In another aspect, a device driver monitors the available buffer space of a network controller buffer to ensure that the network controller has sufficient available buffer space before posting the next transmit request to the network controller. In accordance with yet another aspect, the device driver can copy transmit data from an application buffer to a driver buffer if the size of the transmit data of a particular transmit request is below a programmable threshold. If so, the device driver can notify the application to permit the application buffer to be released.
    • 提供了一种用于管理网络控制器的发送吞吐量的方法,系统和程序。 在一个实施例中,来自应用的发送请求可以由设备驱动程序以发送请求的流水线发布到网络适配器的网络控制器,而不必等待对所述网络控制器的所附送的传输数据的传送的确认。 在另一方面,设备驱动程序监视网络控制器缓冲器的可用缓冲区空间,以确保网络控制器在向网络控制器发布下一个发送请求之前具有足够的可用缓冲区空间。 根据另一方面,如果特定发送请求的发送数据的大小低于可编程阈值,则设备驱动程序可以将发送数据从应用缓冲器复制到驱动器缓冲器。 如果是这样,设备驱动程序可以通知应用程序以允许释放应用程序缓冲区。

    • Techniques are described that can be used to support integrity validation of protocol data units. An iSCSI compatible logic may establish a memory region to store a header portion of the protocol data unit. In some implementations, the iSCSI compatible logic may read the header and determine a size of a second memory region to store a payload portion of the protocol data unit. In some implementations, the iSCSI compatible logic may set the second memory region as a maximum possible size of the payload portion. TCP compatible logic may include the capability to validate an integrity of the header or data portions of the protocol data unit. TCP compatible logic may request data mover logic to determine an integrity validation value for a header and/or data portion of the protocol data unit in the process of copying the protocol data unit to among the memory region or the second memory region. TCP compatible logic may compare the determined integrity validation value with an integrity validation value included with the protocol data unit.
    • 描述了可用于支持协议数据单元的完整性验证的技术。 iSCSI兼容逻辑可以建立存储区域以存储协议数据单元的报头部分。 在一些实现中,iSCSI兼容逻辑可以读取头部并且确定第二存储器区域的大小以存储协议数据单元的有效载荷部分。 在一些实现中,iSCSI兼容逻辑可以将第二存储器区域设置为有效载荷部分的最大可能大小。 TCP兼容逻辑可以包括验证协议数据单元的报头或数据部分的完整性的能力。 TCP兼容逻辑可以在将协议数据单元复制到存储器区域或第二存储器区域的过程中请求数据移动器逻辑来确定协议数据单元的报头和/或数据部分的完整性验证值。 TCP兼容逻辑可以将确定的完整性验证值与协议数据单元所包含的完整性验证值进行比较。
