TECHNOLOGIES FOR A SERVICE QUALITY-CONSCIOUS END-TO-END I / O PLANNING

摘要

End-to-end quality of service technologies for I / O operations include a computing device in an I / O path. The computing device receives an I / O request packet from another computing device in the I / O path. The I / O request packet contains one or more QoS deadline metadata. The QoS deadline metadata provides latency information related to a current workload related to a specified QoS. The data processing device evaluates the QoS deadline metadata and assigns a priority to the I / O request package depending on the evaluated metadata.
