PCIe3 4-Port (10 Gb + 1 GbE) SR+RJ45 Adapter (FC EN0S; CCIN 2CC3)
Learn about the specifications and operating system requirements for the feature code (FC) EN0S adapter.
The PCIe3 4-Port (10 Gb + 1 GbE) SR+RJ45 Adapter is a PCI Express (PCIe) generation 3 (Gen3) x8, short
form-factor, low-profile capable, full-height adapter. The adapter provides two 10 Gb SR optical ports and
two 1 Gb RJ45 ports. This adapter provides a PCIe 3.0 host bus interface. The adapter supports the
Ethernet network interface controller (NIC) function. The adapter is a high-performance adapter that
consolidates traffic for networking. The link aggregation and failover features of the adapter make it
suitable for critical network applications that require redundancy and high availability.
The four-port adapter provides two 10 Gb small form-factor pluggable (SFP+) optical SR transceiver ports
and two 1 Gb RJ45 Ethernet ports. The two 10 Gb SR ports have little connector (LC) duplex-type
connectors. The optical transceiver uses shortwave laser optics and is attached with MMF-850nm fiber
cabling with LC connectors. See "Cables" on page 165 for more information about the optical cables. Each
10 Gb port provides Ethernet connectivity with a nominal data rate of 10 Gbps (gigabits per second).
Figure 74 on page 164 shows the FC EN0S adapter.
Each of the 1 Gb RJ45 port provides Ethernet connectivity at a data rate of 1 Gbps. Each of the 1 Gb ports
is connected with a 4-pair, CAT-5 unshielded twisted pair (UTP) cable or with a cable of higher
specification, and is supported for distances of up to 100 meters. In addition to 1 Gb (1000 Mb) networks,
100 Mb networks are also supported.
The adapter provides the following features:
v The adapter is a PCIe3 NIC network convergence adapter.
v The 10 Gb SR ports can function in the NIC mode.
v The adapter can be used as the host local area network (LAN) adapter.
v The adapter supports interrupt moderation to deliver increased performance while significantly
reducing processor utilization
v The adapter supports dual port operation in any PCIe3 slot
v The adapter supports auto-negotiation, full-duplex only.
v The adapter supports multiple media-access control (MAC) per interface.
v The adapter supports integrated media-access control (MAC) and physical layer (PHY).
v The adapter supports the following standards for the different ports and functions:
– IEEE 802.3ae in the 10 GbE ports
– 802.3ab in the 1 GbE ports
– Ether II and IEEE 802.3 for encapsulated frames
– 802.1p for setting up priority levels in tagged VLAN frames
– 802.1Q for VLAN tagging
– 802.3x for flow control
– 802.3ad for load-balancing and failover
– IEEE 802.3ad and 802.3 for link aggregation
v The adapter provides message signal interrupts (MSI), MSI-X, and support of legacy pin interrupts.
v The adapter supports jumbo frames up to 9.6 KB.
v The adapter supports gigabit EtherChannel (GEC) with the existing software.
v The adapter supports TCP checksum offload transmission control protocol (TCP), user datagram
protocol (UDP), TCP segmentation Offload (TSO) for IPv4 and IPv6.
v Supports TCP segmentation or large send offload
v Supports EEPROM-SPI and single EEPROM
