QoS at thepacket level is realized by using the CS_CTL field, which is specified in theFC-FS-2 specification. QoS allows one to prioritize frames between a hostand target, depending on the value of the CS_CTL field in the FC Frameheader. Extending QoS from the fabric to the host Enables QLogic Fibre Channel users to rapidly scale server virtualizationwithout compromising service-level agreements Benefits for both physical and virtual server deployments Supported configuration: QLogic 2700 Series Adapters CS_CTL-based QoS is end-to-end (requires target to supportCS_CTL)NOTEFor information about end-to-end CS_CTL QoS, see “ConfiguringEnd-to-End CS_CTL QoS” on page 84.
