I think at this point, you are actually asking two or more different questions.  What is it that you are really looking for?  a) openvswitch switching?  b) open flow based switching?  c) hardware accelerated openvswitch?  d) openvswitch to handle open flow hardware acceleration? e) hardware accelerated open flow?

Someone mentioned the Zodiac.  I believe that is an OpenFlow-only switch — you don’t get to run openvswitch or linux on it.  You need to run a separate controller to control the Zodiac.

If you want to run OpenvSwitch on something, you can use almost anything.  I use devices from http://www.lannerinc.com (no personal affiliation) to install Linux and run OpenvSwitch.  Forwarding speeds are amazing, even if they are not hardware accelerated.

OpenvSwitch is a special animal:  it can be used to process-based switch packets between ports.  And it can be used as an software based OpenFlow switch.  it can run on anything you run linux and has multiple network ports.

You can take a look at the LEDE/openwrt projects — I think they use openvswitch in some form for some of their routing/switching/security elements.  That would get you a really inexpensive four port switch, running linux, and some version of openvswitch.  Again, it depends, for what combination of openvswitch/openflow/hardware acceleration are you looking?

If you can wait a bit more, the Mellanox guys are working through an interesting concept of hardware accelerating Openvswitch through the linux tc flower mechanism.  At that point, with mellanox hardware, you can then get Openvswitch/openflow/hardware acceleration, all under one roof.
