The PEX 8680 employs an enhanced version of PLX’s field tested PEX 8648 PCIe switch architecture, which allows users to configure the device in
legacy single-host mode or multi-host mode with up to six host ports capable of 1+1 (one active & one backup) or N+1 (N active & one backup) host
failover. This powerful architectural enhancement enables users to build PCIe based systems to support high-availability, failover, redundant and
clustered systems.
