What PCIe interface does this NIC use and what bandwidth does it provide?

PCIe Gen 3.0 x8 with link rates of 2.5, 5.0, or 8.0GT/s and auto-negotiation to x16/x8/x4/x2/x1. This provides ample bandwidth for simultaneous full line-rate operation across both 25GbE ports without bottlenecking.

Which Ethernet standards and protocols are supported?

Complies with IEEE 802.3 standards for 100/50/40/25/10/1GbE including 802.3bj and 802.3bm. Supports transport protocols TCP/IP, UDP/IP, iSCSI for efficient offloaded networking in virtualized and storage environments.

What form factor and bracket type does it have?

Plug-in card with tall bracket measuring 2.71 x 5.6 inches (68.90mm x 142.24mm). Designed for standard PCIe slots in enterprise servers with bi-color LED per port for link status indication.

Is this NIC suitable for virtualization deployments?

Yes, virtualization-aware networking provides traffic isolation, prioritization, and seamless integration with hypervisors and containers, ensuring predictable performance for VMs sharing physical hosts in cloud-native setups.

What advanced features improve performance?

Direct memory access, intelligent buffering, flow control, and MSI/MSI-X interrupt mechanisms minimize CPU intervention while maintaining consistent throughput under variable traffic in multi-tenant data centers.
