Main Features
1.Intel VT-c Virtualization Technology: SR-IOV and VMDq, enables multiple virtual functions for virtual machines, drastically lowers CPU load in VMware, KVM virtual environments.
2.Full-featured Hardware Offloads: TCP/UDP/IP checksum offload, TSO, RSS, interrupt coalescing, QoS and built-in traffic management.
3.Converged Network & Storage Support: Optimized for iSCSI and NFS storage over Ethernet, unifies LAN and storage traffic on one adapter.
4.Flexible Port Partitioning: Supports breakout mode, each QSFP+ port can split into four independent 10G SFP+ channels.
5.Intel Data Direct I/O (DDIO): Directly delivers network packets to CPU cache, improves throughput and reduces memory access latency.
6.Wide OS Compatibility: Works with Windows Server, RHEL, SUSE Linux, VMware ESXi.
