Interoperability with other 10/25GbE switches and network adapters
Ensures smooth integration with existing infrastructure by supporting SFP+, SFP28, and QSFP28 switches and network adapters for seamless upgrades to 25GbE.
Load Balancing on Multiple CPUs
Enhances performance in multi-processor systems by efficiently distributing network loads across CPU cores using Microsoft RSS or Linux scalable I/O.
Protect, Detect, and Recover
Incorporates platform resiliency aligned with the NIST Cybersecurity Framework, offering firmware and settings verification, corruption detection, and automated recovery to the original state.
Support for Most Network Operating Systems
Enables broad compatibility with diverse application needs.
RoHS-Compliant
Adheres to the EU directive 2011/65/EU for reduced use of hazardous materials.
Time Sync (IEEE 1588, 802.1as)
Synchronizes internal clocks of Ethernet equipment to a network master clock, providing precise timing with latency compensation.

I/O Features for Multi-Core Processor Servers

Intel® Ethernet Flow Director (Intel® Ethernet FD)
Advanced traffic steering for reduced latency and increased transaction rates, ideal for cloud-based applications.
MSI-X Support
Minimizes interrupt overhead and distributes interrupt handling across multiple CPUs.
Multiple Queues (1,536 Tx/Rx per device)
Optimized packet handling with efficient prioritization, reducing buffer overflow risks.
Tx/Rx IP, SCTP, TCP, and UDP Checksum Offloading (IPv4/IPv6)
Lowers processor usage by offloading checksum and segmentation tasks.

Virtualization Features

Next-Generation VMDq
Supports up to 256 VMs, offloading MAC address and VLAN tag sorting from the hypervisor, improving throughput and CPU efficiency.
PCI-SIG SR-IOV Implementation
Provides near-native performance by assigning virtual ports directly to VMs, with up to 128 ports per device (64 per port for dual-port configurations).
Virtual Machine Load Balancing (VLMB)
Balances traffic across VMs, providing fault tolerance against failures in switches, ports, cables, or adapters.
Advanced Packet Filtering
- 1,536 exact-match packets (unicast/multicast).
- 512 hash entries for unicast and multicast.
- Supports promiscuous mode and optional invalid frame filtering.
VLAN Support
Handles up to 4,096 VLAN tags, enabling the creation of multiple VLAN segments.
VxLAN, NVGRE, GENEVE, VxLAN-GPE+NSH, MPLS
Ensures high application performance in virtualized network environments.
