The Allied Telesis' range of Fast Ethernet Media converters provides a complete series of conversion devices, allowing users to extend the size of UTP & multi-mode fiber networks with the use of single-mode fiber cabling. Supporting SC-connected single-mode fiber, these converters can be used to extend networks up to a distance of 2km. All these media converters feature an internal MDI/MDIX switch, allowing the converter to be connected to PC, hub or switch with a simple UTP cable. The media converters also allow the installer to test the integrity of fiber connection, by forcing the converters to communicate over the fiber cable. This Link Test feature allows installers to check for cable faults without the need for expensive fiber optic test equipment. ...

AT-2973SX PCIe x 4 (channels) dual port fiber Gigabit interface card optimized for virtualization Using multi-port cards in virtualized environments critical to the application in order to provide redundancy & data connectivity for the workloads in the virtual machines. Due to specific slot limitations & the need for redundancy/data connectivity, it is usually recommended virtualized servers use at least six Gigabit ports to satisfy the I/O demands. Virtual Machine Device Queues (VMware Direct Path) VMware Direct Path (SR-IOV) reduces I/O overhead on the hypervisor in a virtualized server by performing data sorting & uniting it in the network silicon (this feature requires an O/S that supports VMDq). This technology makes use of multiple queues in the network controller. As data packets enter the card, they are sorted, & packets traveling to the same destination/ virtual machine get grouped together in a single queue. The packets are sent to the hypervisor, which directs them to their respective virtual machines. Taking the strain of packet filtering & sorting from the hypervisor improves overall CPU usage & throughput. The AT-2973SX Gigabit interface card provides enhanced performance with the next generation (VMDq) technology, which

Includes:: features such as loop back (inter-VM communication), priority-weighted bandwidth management, & doubling the number of data queues per port from 4 to 8. It also supports multicast & broadcast data on a virtualized server.
