Configuring CS_CTL QoS
This section provides the following information on class-specific control (CS_CTL)
quality of service (QoS):
 CS_CTL QoS Features
 Enabling CS_CTL QoS Mode for the Initiator and Target Ports
 Verifying and Confirming CS_CTL Mode Setup for Each Port
 Creating a Virtual Port from the Adapter’s Port in QConvergeConsole GUI
 Setting the QoS Priority Level for a Virtual Port in QConvergeConsole GUI
CS_CTL QoS Features
The following highlights some of the features of the CS_CTL QoS:
 Traffic priority classification for QLogic Gen6 Fibre Channel SAN. QoS at the
packet level is realized by using the CS_CTL field, which is specified in the
FC-FS-2 specification. QoS allows one to prioritize frames between a host
and target, depending on the value of the CS_CTL field in the FC Frame
header.
 Extending QoS from the fabric to the host
 Enables QLogic Fibre Channel users to rapidly scale server virtualization
without 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 support
CS_CTL)
NOTE
For information about end-to-end CS_CTL QoS, see “Configuring
End-to-End CS_CTL QoS” on page 84 .
