PCIe3 LP 2-Port 10 GbE NIC and RoCE SR Adapter (FC EC2M; CCIN 57BE)

Learn about the specifications and operating system requirements for the feature code (FC) EC2M adapter.

Overview

The FC EC2N and EC2M are the same adapter. FC EC2N is a full-height adapter and FC EC2M is a low-profile adapter. The names of these two adapters are:
  • FC EC2N: PCIe3 2-Port 10 GbE NIC and RoCE SR adapter
  • FC EC2M: PCIe3 LP 2-Port 10 GbE NIC and RoCE SR adapter

This PCIe Gen3 adapter provides two 10 Gb SR optical fiber ports. The adapter is a converged network adapter supporting both NIC and IBTA RoCE standard. RoCE is Remote Direct Memory Access (RDMA) over Converged Ethernet. Using RoCE, the adapter can support significantly greater bandwidth with low latency and minimize CPU overhead by more efficiently using memory access. This offloads the CPU from I/O networking tasks, improving performance and scalability.

The adapter has two preinstalled optical transceivers. Little connector (LC) type connectors connect the adapter to standard 10-Gb SR optical cabling and provide up to 300 m (984.25 ft) cable length. The two transceiver ports are used for connectivity with other servers or switches in the network. Each port provides Ethernet connectivity with a nominal data rate of 10 gigabits per second (Gbps). The link aggregation and failover features of the adapter are ideal for critical network applications that require redundancy and high availability. Figure 1 shows the FC EC2M adapter.

The adapter provides the following features:
  • The adapter is a PCIe3 NIC network convergence adapter.
  • The adapter supports RoCE and NIC functions but not concurrently on same adapter.
  • The adapter supports the following standards for the different ports and functions:
    • AIX NIM and Linux Network Install are supported
    • IBTA RoCE v2 support
    • 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
  • The adapter provides message signal interrupts (MSI), MSI-X, and support of legacy pin interrupts.
  • The adapter supports jumbo frames up to 9.6 KB.
  • The adapter supports gigabit EtherChannel (GEC) with the existing software.
  • The adapter supports TCP checksum offload transmission control protocol (TCP), user datagram protocol (UDP), TCP segmentation Offload (TSO) for IPv4 and IPv6.
  • Supports TCP segmentation or large send offload
  • Supports EEPROM-SPI and single EEPROM
  • Compliant with European Union Directive 2002/95/EC on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment
