What are the key connectivity specs of the 900-9X624-0083-SB0?

Dual-port SFP28 at 25GbE speeds via OCP 3.0 form factor and PCIe 4.0 x16 host interface. Supports optical fiber transceivers for low-latency, high-throughput Ethernet with backward compatibility to PCIe 3.0.

Does this adapter support RDMA and storage acceleration?

Yes, features RoCEv2, NVMe-oF, and GPUDirect Storage offloads for ultra-low latency data transfer. Ideal for AI clusters and disaggregated storage, reducing CPU overhead while sustaining 50Gbps aggregate throughput.

What security features are included?

Integrated crypto engine for IPsec/TLS acceleration and secure boot to prevent firmware tampering. Ensures compliance in multi-tenant cloud environments with hardware-rooted trust.

Is it compatible with virtualization platforms?

Supports SR-IOV for up to 127 virtual functions, VXLAN/Geneve overlays, and overlay acceleration. Optimized for VMware, KVM, and Hyper-V with high VM density in data centers.

What form factor and installation options exist?

OCP 3.0-compliant card with thumbscrew pull-tab brackets for tool-less installation. Fits standard server OCP NIC slots, optimized for airflow in high-density racks.

How does PCIe 4.0 benefit performance?

Provides 64GT/s bandwidth per lane, enabling full wire-speed 25GbE on both ports without bottlenecks. Doubles PCIe 3.0 capacity for future-proofing high-bandwidth workloads.
