PCIe4 2-port 100GbE RoCE with Crypto x16 adapter (FC EC78; CCIN 2CFA)
Learn about the specifications and operating system requirements for feature code (FC) EC78 adapters.
FC EC78 is a full-height adapter.
The PCIe4 2-port 100GbE RoCE with Crypto x16 adapter is a PCI Express (PCIe) generation 4 (Gen4) x16 adapter. The adapter provides two 100GbE En ConnectX-6 DX QSFP56 ports. The secure-key adapter provides both cryptographic coprocessor and cryptographic accelerator functions in a single PCIe card. This adapter is suited to applications that require high-speed, security-sensitive, RSA acceleration, cryptographic operations for data encryption and digital signing. Additionally, the adapter is useful in secure management, use of cryptographic keys, or custom cryptographic applications. It provides secure storage of cryptographic keys in a tamper-resistant hardware security module that is designed to meet FIPS 140-2 level 4 security requirements. The adapter runs in dedicated mode only.

For 100G, IBM® offers either Direct Attach Copper (DAC) cables up to 2 M or Active Optical Cables (AOC) up to 50 M. QSFP based transceivers are included on each end of these cables. For more information about adapter cabling, see the Cable and transceiver matrix.
IBM qualifies and supports QSFP optical transceiver (FC EB59) to install into the adapter. Customers can also use their own optical cabling and QSFP56 optical transceiver for the other end. This is a 100Gbase-SR4 based active optical transceiver capable up to 100 M through the OM4 cable or 70 M through OM3 cable. Either one or both of the adapter's two QSFP56 ports can be populated. When two ports are filled, both can have copper cables or optical cables. Additionally, one of the cables can be copper and the other can be optical.
