HTTPS Accelerator Card Support

For customers that have more than 20% - 25% of their total traffic as HTTPS, IWSVA has drivers that support HTTPS accelerator cards, which can be used for all of the high computational calculations needed for HTTPS and save the general purpose CPU cycles for other IWSVA functions, such as content inspection. The accelerator card is designed to offload the CPU intensive operations of SSL key pair negotiation, decryption of the HTTPS stream for content inspection, and re-encryption of the content for secure delivery to the client workstation.

IWSVA supports 2 types of Silicom cards:

Using the accelerator card allows systems to offload high-level SSL or IPsec protocol commands that reduce the host I/O traffic and system processor to increase the total system throughput. This also frees system processor resources for other functions, increasing overall system performance.
