Exablaze Exalink 50
ULTRA LOW LATENCY 50 PORTS LAYER 1 SWITCH
The ExaLINK is an exciting new network device with numerous applications including datacenter infrastructure, financial trading, telecommunications and high performance computing. It allows for dynamic reconfiguration of network topology, data broadcast from one port to multiple ports, and mirroring of data for network monitoring, all while adding negligible latency to a network. An ExaLINK is much faster than a traditional Ethernet switch and far more flexible than a tree of optical splitters.
LATENCY AS LOW AS 2.4 NANOSECONDS
The administrator can configure links between any two ports of the ExaLINK, or between one input port and multiple output ports. Once a link is configured, data is forwarded through the device in as little as 2.4 nanoseconds and at most 4.6 nanoseconds.
The overhead is typically less than 5 nanoseconds even including optical transceivers. In comparison, it takes light approximately 5 nanoseconds to travel through 1m (3.3ft) of optical fiber. In other words, the ExaLINK adds negligible latency to a network.
ELECTRONIC PATCH PANEL
Used as a top-of-rack device, the ExaLINK can simplify the management of network connections within a rack, especially if servers are located in a remote location.
If network connections are passed through an ExaLINK, connectivity can be set up and reconfigured at will, without requiring physical visits to the datacenter or expensive calls to ‘remote hands’ staff. In the case of equipment or server failure, connections can be repatched appropriately. Inputs and outputs do not need to be the same media, so the ExaLINK can also perform a media conversion function.
REPLICATE AND DISTRIBUTE
Incoming data can be sent to more than one output port - in fact, it could be sent to all 49 other ports - so the ExaLINK is perfectly suited for low-latency data distribution from one source to multiple receivers.
This same functionality can also be used for mirroring data ports for network monitoring, timing measurement, or audit. Unlike optical splitters, the ExaLINK is dynamically configurable to allow servers to be connected and disconnected as required, and there are no concerns about optical signal loss.
The ExaLINK can be configured and monitored through a web browser, command line interface (CLI) or Simple Network Management Protocol (SNMP).
An intuitive web interface allows simple point-and-click management. Alternatively, a command line interface can be accessed through SSH, telnet or the front panel serial port. Detailed information about each port’s signal level and signal quality, including a graphical eye diagram, is available to aid in troubleshooting connections. SNMP support is also available for integration with remote management tools.
The ExaLINK comes standard with dual redundant power supplies and fans to minimize downtime.
It has been successfully deployed in mission-critical environments around the world, proving itself as a robust solution that gives systems administrators and network engineers flexibility and visibility into their networks while adding next to zero latency.
