Lantronix N-TGE-SFP-02 User Guide Feature Descriptions MR-IOV (Multi-Root IOV) allows I/O PCI Express to share resources among different VMs on different physical machines. MSI (Message Signaled Interrupts) can allocate 1, 2, 4, 8, 16 or 32 interrupts. MSI-X allows up to 2048 interrupts. RSS/TSS (total sum of squares ( TSS ) = explained sum of squares (ESS)+ residual sum of squares (RSS)). Linux: 64 RSS PF queues / 4 VF queues2; Windows: 32 RSS PF queues / 4 VF queues. SRIOV (single root input/output virtualization): In virtualization, the SR-IOV specification allows the isolation of PCI Express resources for manageability and performance reasons. A single physical PCI Express bus can be shared in a virtual environment using the SR-IOV specification. SR-IOV allows different virtual machines (VMs) in a virtual environment to share a single PCI Express hardware interface. Teaming options in Windows are available using the Intel PROSet Adapter Utility. Adapter teaming with Intel® Advanced Network Services (Intel® ANS) uses an intermediate driver to group multiple physical ports. You can use teaming to add fault tolerance, load balancing, and link aggregation features to a group of ports. Advanced Networking Services (ANS) team names are limited to 48 characters. Team names must be unique within the system. At Type, select the team type. Adapter Fault Tolerance (AFT) provides redundancy through automatic failovers from an active adapter to a standby adapter in the case of switch port, cable, or adapter failure. Adaptive Load Balancing (ALB) provides transmit traffic load balancing and fault tolerance in the event of switch port, cable, or adapter failure. IEEE 802.3ad Dynamic Link Aggregation is an IEEE standard for increasing throughput between switches or a server and switch. This is accomplished by dynamically bundling or channeling several ports together and showing them as a single link using Link Aggregation Control Protocol (LACP). This increases the total bandwidth for the link and provides fault-tolerance in the event of switch port, cable, or adapters failure. Switch Fault Tolerance (SFT) provides redundancy across switches. An adapter connected to one switch will automatically failover to a standby adapter connected to a different switch in the event of a switch, switch port, cable, or adapter failure. Static Link Aggregation (SLA) is a performance technology developed to increase throughput between switches or a server and switch. This is accomplished by bundling or channeling several ports together and showing them as a single link. This increases the total bandwidth for the link and provides fault- tolerance in the event of a switch port, cable, or adapter failure. Virtual Machine Load Balancing (VMLB) provides transmit and receive traffic load balancing across Virtual Machines bound to the team interface, as well as fault tolerance in the event of switch port, cable, or adapter failure. IEEE 802.1p QoS: You can adjust the allocation of the Transmit Buffers depending on the packet priority. Using the Advanced driver setting you can allow packet priority and VLAN, and also adjust the size of the Transmit buffer. Other detailed firmware tools can be used for adding priority to Ethernet packets. These tools are OS dependent. 33819 Rev. B https://www.lantronix.com/ 5
