7.3.54 GARP VLAN Registration Protocol

All OSA-Express5S and OSA-Express4S features support VLAN prioritization, a component
of the IEEE 802.1 standard. GARP VLAN Registration Protocol (GVRP) support allows an
OSA-Express port to register or unregister its VLAN IDs with a GVRP-capable switch and
dynamically update its table as the VLANs change. This process simplifies the network
administration and management of VLANs because manually entering VLAN IDs at the
switch is no longer necessary.
The minimum support requirements are listed in Table 7-46.

7.3.55 Inbound workload queuing for OSA-Express5S and OSA-Express4S

OSA-Express3 introduced inbound workload queuing (IWQ), which creates multiple input
queues and allows OSA to differentiate workloads "off the wire." It then assigns work to a
specific input queue (per device) to z/OS. The support is also available with OSA-Express5S
and OSA-Express4S. CHPID types OSD and OSX are supported.
Each input queue is a unique type of workload, and has unique service and processing
requirements. The IWQ function allows z/OS to preassign the appropriate processing
resources for each input queue. This approach allows multiple concurrent z/OS processing
threads to process each unique input queue (workload), avoiding traditional resource
contention. In a heavily mixed workload environment, this "off the wire" network traffic
separation is provided by OSA-Express5S and OSA-Express4S. IWQ reduces the
conventional z/OS processing that is required to identify and separate unique workloads. This
advantage results in improved overall system performance and scalability.
