Techniques for Moving Data between a Network Input/Output Device and a Storage Device

机译:在网络输入/输出设备和存储设备之间移动数据的技术

摘要

Examples are disclosed for moving data between a network input/output (I/O) device and a storage subsystem and/or storage device. In some examples, a network I/O device coupled to a host device may receive a data frame including a request to access a storage subsystem or storage device. The storage subsystem and/or storage device may be located with the network I/O device or separately coupled to the host device through a storage controller. One or more buffers maintained in a cache for processor circuitry may be used to exchange control information or stage data associated with the data frame to avoid or eliminate use of system memory to move data to or from the storage subsystem and/or storage device. Other examples are described and claimed.
