IBM feature #EC38 is the PCIe3 2-port 10 GbE NIC & RoCE SFP+ Copper Adapter, CCIN 57BC, a full-height adapter for IBM Power Systems. Feature #EL3X, the PCIe3 LP 2-Port 10 GbE NIC and RoCE SFP+ Copper Adapter for Linux, is the low-profile form of the same CCIN 57BC card.
It is a PCIe generation 3, dual-port 10 Gigabit Ethernet adapter with a PCIe 3.0 host bus interface. Both 10 Gb ports are SFP+ ports for copper twinax cabling, and the cables carry the copper transceivers. The adapter is a converged network adapter supporting NIC and the IBTA RoCE standard (RDMA over Converged Ethernet), with NIC and RoCE not used concurrently on the same adapter. RoCE moves I/O networking tasks off the CPU. Active copper twinax cables up to 5 m are supported, such as #EN01, #EN02 and #EN03.
The adapter FRU number is 00RX859, with low-profile tailstock part number 00RX856. The bus is PCIe3 x8 at 3.3 V in a short form factor. Features include IBTA RoCE v2, AIX NIM and Linux Network Install, MSI and MSI-X interrupts, jumbo frames up to 9.6 KB, TCP checksum offload and TCP segmentation offload for IPv4 and IPv6, and IEEE 802.3ad link aggregation, load-balancing and failover.
Supported operating systems are AIX 6.1 with 6100-09 and Service Pack 5 and APAR IV68443 or later, AIX 7.1 with 7100-03 and Service Pack 5 and APAR IV68444, Red Hat Enterprise Linux 7.1 or later and 6.6 or later, SUSE Linux Enterprise Server 12 or later, Ubuntu 15.04 or later, and VIOS 2.2.3.51 or later with NIC capability only. IBM i 7.1 Technology Refresh 9 or later and 7.2 Technology Refresh 1 or later run only through VIOS with virtual Ethernet.
