[Openvpn-users] Hardware acceleration

Hi all,

I'm trying to find a hardware acceleration solution for use with OpenVPN
(openvpn.sourceforge.net).
I am trying to increase the throughput of established SSL tunnels without
adding more boxes / procs / etc.
We're targeting RedHat Enterprise Linux 3.0, which currently uses OpenSSL
0.9.7a (openssl-0.9.7a-22.1.*.rpm).

It looks as though there are several cards supported by the -engine and
0.9.7 releases, as well as
several vendors that have "modified" OpenSSL sources... but finding the
right card (and published
specs) has been a little difficult.

My question is, basically, does anyone have any good knowledge about a
hardware accelerator card
(PCI or PCI-X preferably) that works with OpenSSL's SSL/TLS and EVP APIs?
The SSL/TLS will accelerate
the handshake / establishment phase of building an OpenVPN tunnel, but I
need the EVP interface
to accelerate throughput of the tunnel itself.  Any information would be
great, but numbers on
how much acceleration a particular card could do would be even greater :)

Thanks,
Brenton
