PEX8516-BB25BIG Product Details

The ExpressLane PEX 8516 device offers PCI Express switching capability enabling users to add scalable high bandwidth, non-blocking interconnection to a wide variety ofapplications including servers, storage systems, communications platforms, blade servers, and embedded-control products. The PEX 8516 is well suited for fan-out, aggregation, peer-to-peer, and intelligent IO module applications.

The ExpressLane PEX 8516 offers highly configurable ports. There are a maximum of 4 ports that can be configured to any legal width from x1 to x8, in any combination to support your specific bandwidth needs. The ports can be symmetric (each port having the same lane width) or asvmmetric (ports having different lane widths). Any of the ports can be designated as the upstream port, which can be changed dynamically.
