What are the key connectivity specifications of the 900-9X6AG-0066-ST0?

Dual-port QSFP56 ports support 100/50/40GbE Ethernet with copper twinax or optical transceivers. PCIe 4.0 x16 (16 GT/s) provides 64GB/s bidirectional bandwidth, backward compatible with PCIe Gen3. Full-height bracket fits 1U/2U servers; dimensions 142x68.9mm enable dense deployments.

Does this adapter support hardware security features?

Yes, includes hardware crypto acceleration for IPsec, TLS offloads, and secure boot. Protects data-in-transit in sensitive environments like finance or government clouds. Reduces CPU overhead for encryption while maintaining wire-speed 100GbE performance across both ports.

What power consumption should I expect in deployment?

Typical 18.7W (PCIe Gen3)/19.52W (Gen4) with passive cables; max 25.28W/26.64W. Each QSFP56 port adds up to 5W. 3.3V AUX voltage, 100mA max current. Optimized for air-cooled servers with 550-700 LFM airflow.

Is it suitable for NVMe over Fabrics storage?

Yes, RDMA over Converged Ethernet (RoCEv2) enables NVMe-oF with sub-microsecond latencies. Supports large on-chip buffers, QoS, and multi-queue for disaggregated storage in Ceph or custom fabrics, scaling to thousands of NVMe drives.

What environmental tolerances does it have?

Operational: 0-55°C, 10-85% RH non-condensing, up to 3050m altitude. Storage: -40-70°C, -10-90% RH. Meets RoHS standards. Passive cooling requires 550 LFM (hot aisle); active cables need 700 LFM for sustained 100GbE.

What servers are compatible with this PCIe adapter?

PCIe 4.0 x16 slots in NVIDIA DGX, HPE ProLiant DL360/380, Dell PowerEdge R750, Supermicro SYS-740GP. Backward compatible with Gen3 x16. Full-height bracket; check chassis clearance for 142mm length.
