Product Description
IBM EC3B PCIe3 2-Port 40GbE NIC RoCE QSFP+ Adapter
- 40GbE QSFP+
- 2-Ports
IBM EC3B PCIe Gen3 adapter provides two 40 Gb Ethernet QSFP+ ports. NIC and IBTA RoCE protocols are supported.
RoCE is Remote Direct Memory Access (RDMA) over Converged Ethernet. RoCE 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 #EC3A/EC3B adapter does not include transceivers. Shorter distance copper cables include transceivers on the end of the QSFP+ cable (see #EB2B (1m), #EB2H (3m), #ECBN (5m)). For longer distance use two optical SR transceiver (two #EB27). QSFP+ optical cables to be used with the #EB27 transceiver are #EB2J (10m) or #EB2K (30m). Do not mix copper and optical on the same adapter.
