- Product Description - 

        XYT-40G-Ethernet Adapters with SFP+/SFP28/QSFP+ connectivity are the most flexible and scalable for demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 40 Gigabit connections. The adapters provide flexible and scalable I/O solutions to meet the diverse requirements of running mission-critical applications in virtualized and unified storage environments. With a reliable performance in a flexible LAN and SAN networks, the server adapters can meet the demand of next-generation data centers by providing unmatched features for both server and network virtualization.

 - Product Features - 

1.SUPPORT FOR FIBER CHANNAL OVER ETHERNET (FCoE)

FCoE encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 40GbE networks while preserving its native protocol.

2.SUPPORT FOR ISCSI

The adapters provide complete support for proven native OS and VMM iSCSI initiators as well as iSCSI boot. The Ethernet adapter truly delivering on the promise of unified networking. The adapters do it all: 40G LAN, FCoE, and iSCSI.

3.I/O FOR VIRTUALIZED

I/O bottlenecks are reduced through intelligent offloads such as Virtual Machine Device Queues (VMDq) and Flexible Port Partitioning, using SR-IOV for networking traffic per Virtual Machine (VM), enabling near-native performance and VM scalability.

4.VMDQ FOR EMULATED PATH

VMDq, enables a hypervisor to represent a single network port as multiple network ports that can be assigned to the individual VMs. Traffic handling is offloaded to the network controller, delivering the benefits of port partitioning with little to administrative overhead by the IT staff.

5.SR-IOV FOR DIRECT ASSIGNMENT

Adapter-based isolation and switching for various virtual station instances enable optimal CPU usage in virtualized environments. With Virtual Functions each VF can support a unique and separate data path for I/O related f unction within the PCI Express* hierarchy. Using SR-IOV with a networking device, allows to be partitioned into smaller slices that can be allocated to specific VMs or guests.

6.PCI-SIG IMPLEMENTATION

PCI-SIG provides an implementation of the PCI-SIG standard for I/O Virtualization. The physical configuration of each port is divided into multiple virtual ports. Each virtual port is assigned to an individual VM dir, integrated with Intel® VT for Directed I/O  (Intel®  VT-d)  to  provide  data  protection  between VMs by assigning separate physical addresses in the memory to each VM.
