The two 40 Gb quad (4-channel) small form-factor pluggable (QSFP+) transceiver ports are used for
connectivity with other servers or switches in the network. Each QSFP+ port provides Ethernet
connectivity with a nominal data rate of 40 gigabits per second (Gbps).
The adapter does not include transceivers. Use copper cables with QSFP+ 40G BASE-SR transceivers for
short distances. See "Cables" on page 37 for more information about the cables.
For details about slot priorities and placement rules, see PCIe adapter placement rules and slot
priorities(http://www.ibm.com/support/knowledgecenter/POWER8/p8eab/
p8eab_mtm_pciplacement.htm) and select the system you are working on.
The adapter provides the following features:
v Data center bridging support (IEEE standard version CEE)
v T11.3 FC-BB-5 FCoE
v TCP/IP stateless offload in hardware
v Traffic steering across multiple cores
v Hardware-based Single root I/O virtualization (SR-IOV) capable
v Intelligent interrupt coalescence
v Advanced Quality of Service (QoS)
v RoHS-R6 compliant
v RDMA over Ethernet using uDAPL
The adapter provides Ethernet NIC support with the following features:
v 64-bit kernel environments
v multi-processor safe
v AIX Common Data Link Interface (CDLI) compliant
v Concurrent operation of NIC and RoCE device drivers while sharing the same physical port
v Standard frames (1518 bytes + 4 bytes for VLAN tag)
v Jumbo frames (9018 bytes + 4 bytes for VLAN tag)
v IPV4 or IPV6 transmit/receive TCP checksum offload
v IPV4 transmit TCP segmentation offload (commonly known as large send)
v IPV4 receive TCP segmentation aggregation (commonly known as large receive)
v Enhanced Error Handling (EEH) from PCI bus errors
Figure 33 on page 37 shows the adapter.
