How to: Configure FastL4 ePVA settings for deployment through BIG-IP Next Central Manager


The embedded Packet Velocity Acceleration (ePVA) chip is a hardware acceleration Field Programmable Gate Array (FPGA) that delivers high-performance Layer 4 (L4) IPv4 throughput. The use of an FPGA allows the ePVA firmware to be updated, as required, for future upgrades and hotfixes.
