NVIDIA 900-9X662-0073-ST0 | ConnectX-6 Lx Dual-Port 25GbE Network Adapter, PCIe 4.0 x8

Q: What network speeds does this adapter support?
A: The ConnectX-6 Lx supports 1GbE, 10GbE, and 25GbE speeds on each SFP28 port. Speed negotiation is typically automatic based on the connected switch and transceiver, though manual configuration is available when needed.

Q: Is this adapter compatible with virtualized environments?
A: Yes, the adapter features full SR-IOV hardware virtualization support with VirtIO offload capabilities. The ASAP2 technology accelerates virtual switch (vSwitch) and virtual router (vRouter) performance, making it ideal for VMware, KVM, and containerized cloud deployments.

Q: What is the difference between this model and the crypto-enabled variant?
A: This SKU (900-9X662-0073-ST0) includes secure boot functionality but does not include hardware crypto acceleration for IPsec or TLS offloads. The crypto-enabled variant (SKU 900-9X662-0083-ST0) adds inline encryption/decryption capabilities for data-in-motion workloads.

Q: Does this adapter support RDMA functionality?
A: Yes, the ConnectX-6 Lx includes RoCEv2 (RDMA over Converged Ethernet) with Zero Touch RoCE capability, allowing RDMA payloads to run on existing networks without requiring PFC or ECN configuration, simplifying deployment for low-latency storage and HPC applications.

Q: What PCIe slot is required for installation?
A: The adapter requires a PCIe Gen 4.0 x8 or x16 slot and is backward compatible with PCIe Gen 3.0. It ships with a tall bracket and is designed for standard server chassis with half-height, half-length card support.
