PCI-E NIC Cards provide redundant connectivity to ensure an uninterrupted network connection.
PCI-E NIC Cards are ideal for VM environments with multiple operating systems, requiring shared or dedicated NICs.
They are specially designed for desktop PC clients, servers, and workstations with few PCI Express slots available.

An easy way to quickly boot your PCIe-connected FPGA
If your FPGA design is connected as a PCIe device, chances are you need your design to respond within the PCIe specification’s 100msec boot-time requirement. Two new features of the Xilinx Vivado Design Suite starting with the 2013.2 release permit you to boot the PCIe portion of your FPGA in much less than 100msec. These new configuration options are called “Tandem PROM” and “Tandem PCIe.”
Both of these Tandem Configurations order the configuration bit stream contents of a Xilinx 7 series All Programmable FPGA device into a 2-stage bit stream so that the configuration frames required to set up the PCIe IP core are loaded first. The bit stream’s first stage configures the Xilinx PCIe IP as quickly as possible.
Once all of these frames are loaded, the PCIe port on the device becomes active and can support link training and other PCIe events. Immediately after (or later), the second configuration bit stream stage loads the remaining programming information for the rest of the All Programmable device. This second-stage bit stream can be supplied either by the local configuration boot PROM (Tandem PROM) or over the PCIe link (Tandem PCIe).
Using this technique, the PCIe link on the All Programmable device becomes operational well before the 100msec requirement.
