Techniques associated with server transaction latency information

摘要

Examples are disclosed for determining or using server transaction latency information. In some examples, a network input/output device coupled to a server may be capable of time stamping information related to ingress request and egress response packets for a transaction. For these examples, elements of the server may be capable of determining transaction latency values based on the time stamped information. The determined transaction latency values may be used to monitor or manage operating characteristics of the server to include an amount of power provided to the server or an ability of the server to support one or more virtual servers. Other examples are described and claimed.

主权项

1. An apparatus comprising:
circuitry for a network input/output device; a time stamp module executed by the circuitry to place separate time stamps on ingress request packets destined for a server coupled to the network input/output device and place separate time stamps on egress response packets sourced from the server; a capture module executed by the circuitry to capture portions of separate ingress request packets and portions of separate egress response packets, the captured portions to identify the separately time stamped ingress request packets and the separately time stamped egress response packets; and a forward module executed by the circuitry to forward the captured portions with respective time stamps to circuitry maintained at the server using a transport protocol in compliance with a specification to include Management Component Transport Protocol (MCTP) Host Interface Specification, the circuitry maintained at the server included in a chipset; the chipset a processor for the server, the processor to execute an operating system and a network input/output device driver implemented as part of the operating system, the forward module to forward the captured portion to the circuitry maintained at the server.
