Hi all,

A bit off topic, but has anyone had any experience with OpenVPN using
accelerator cards supported by OpenSSL?

We're looking at trying to raise the number of simultaneous tunnels that a
box can support
by using some of the various PCI cards available and supported by OpenSSL
vendor patched OpenSSL).  A lot of the cards available talk about
connections per second
for SSL applications but we want to increase the throughput of established

I have no idea if any of these would actually work, but it would be great if
it did :)

We'd like to use a 3DES+SHA1 for the tunnel cipher; AES cards seem too
expensive for
our needs.  Currently, we've been looking at the Cavium NITROX boards (which
Cavium's "modified OpenSSL") - it seems to have a high throughput for
3DES+SHA1, but
I have no idea if that's properly utilized with OpenSSL/OpenVPN.

If anyone has used any of these cards with OpenVPN, I'd love to hear about
experiences and/or recommendations.
