Table 3-5 shows the maximum number of SMB Direct active (client mode) connections
that can be initiated on Windows Server 2012 and Windows Server 2012 R2 using the
OCe14000-series adapters.
The Maximum Queue Pair counts on a 1-port, 2-port, and 4 port OCe14000-series
adapter are as follows:
Figure 3-16 Resource Counts on a 1-Port 10Gb or 40Gb OCe14000-Series Adapter
Figure 3-17 Resource Counts on a 2-Port 10Gb OCe14000-Series Adapter
Figure 3-18 Resource Counts on a 4-Port 10Gb OCe14000-Series Adapter
SMB Direct does not take these adapter-reported limits into consideration when
creating SMB Direct connections because the driver may still get a request to create
more QPs or memory regions than are supported.
Note: OCe14000-series adapters will fail to create a memory region or QP if it exceeds
the limits of what is supported. The per-port maximum active connections and
the maximum passive connections cannot exceed the MaxQueuePairCount. See
Table 3-5, SMB Direct Active Connections (Client Mode) Per Port for
OCe14000-Series Adapters, on page 640 for more information.
