FAQs

Q: What are the key use cases for the ConnectX-6 Dx adapter?
A: The ConnectX-6 Dx is optimized for data center applications requiring high throughput and low latency, including virtualized environments with SR-IOV, software-defined networking with OVS offload, RDMA storage over RoCEv2, inline security processing with IPsec/TLS offload, and high-performance computing clusters. It accelerates both north-south and east-west data center traffic.

Q: Does this SKU support hardware cryptographic offload?
A: No, the 900-9X6AG-0056-ST1 is the non-crypto version with crypto disabled. While it supports secure boot, it does not include hardware acceleration for IPsec or TLS encryption/decryption. Organizations requiring inline crypto offload should select a crypto-enabled ConnectX-6 Dx SKU.

Q: What cables and transceivers are compatible with the QSFP56 ports?
A: The QSFP56 ports support a wide range of connectivity options including passive and active Direct Attach Copper cables, Active Optical Cables, and QSFP56 optical transceivers for SR/LR multimode and single-mode fiber links. The adapter also supports breakout configurations such as 1x100G to 4x25G or 2x50G depending on switch capabilities.

Q: Can this adapter be used in PCIe Gen 3.0 systems?
A: Yes, the ConnectX-6 Dx is backward compatible with PCIe Gen 3.0 systems. While a PCIe Gen 4.0 x16 slot provides up to 200Gb/s of bandwidth, the adapter will function in PCIe Gen 3.0 x16 slots with sufficient bandwidth to support dual 100Gb/s ports for most workloads. Power consumption is slightly lower at 18.7W typical in Gen 3.0 mode.

Q: What RDMA capabilities does this adapter provide?
A: The ConnectX-6 Dx supports RoCEv2 (RDMA over Converged Ethernet version 2) with hardware offload for RDMA operations, enabling ultra-low latency data transfers for storage, clustering, and HPC applications. It includes programmable congestion control, PFC (Priority Flow Control), ECN (Explicit Congestion Notification), and zero-touch RoCE features for simplified deployment.
