This presentation will cover Neterion's X3100 series 10Gbps Ethernet Network adapters. In this session we will go over the architecture of the adapter, highlighting how the technology can alter the IT infrastructure so as to reduce overall physical footprint and enable more I/O services and flexibility. Implementation examples will include virtualized environments to illustrate performance potential.

Neterion's line of adapters are built for I/O virtualization from the ground up. It offers a multi-channel design built directly in the silicon that is absolutely unique in the industry. It features totally independent hardware-based transmit and receive paths that can be reset independently, support true Quality of Service (QoS), and provide complete resource isolation for all the virtualized instances. Finally, Neterion offers the first SR- and MR- IOV compliant controllers in the market, with the X3100.

Post-presentation follow-up from Glenn Hechler:

1. I misspoke on the dual-port adapter. There are only 17 functions, not 2x17. It can be configured active/passive for on-adapter failover that occcurs in <1ms. In active/active mode the L2 switch is typically turned off. Inbound can burst to 20Gb/s, 16Gb/s sustained. Outbound is limited to 10Gb/s. Multi-function options are different than the single-port. A special configuration of active/active with L2 turned on may be available.

2. I confused SFP/SFP+ with active/passive. It is SFP+ and supports both active and passive cabling. Active twinax cables can be 15m, passive is 7m using certified cables.

3. The adapters are PCIe 1.x, with a transfer rate of 2.5GT/s, throughput of 250MB/s.

4. Not on the slides: power consumption is 12W (typical).
