F5 went to Linux many years ago

Juniper is still FreeBSD. They win this one ;)

NetApp has a port to Linux, but is still shipping FreeBSD. 50/50.

Nokia/CheckPoint went to Linux (SecurePlatform)

Juniper Networks is actively hiring software engineers with FreeBSD experience:

And they're not the only ones...

This is the first I've heard of this. Source?

I too would be interested, I was at NetApp when they acquired Spinnaker which was using Linux and that product was ported over to FreeBSD. That said NetApp has been a huge supporter of getting solid NFS support in Linux both through the pNFS effort and the work that was done at Citi/UMich.

That post is 6 years old and ONTAP has been through at least 3 major releases since then.

Additionally, the post states that the purpose of ONTAP on Linux was to simulate ONTAP for testing & education purposes. In 2006 this was probably the easiest way, but those needs have been met for years by the VMware images NetApp provides.

So, this almost certainly does not exist anymore.

I heard during some NetApp training I took (not certain how authoritative my instructor was)that Data OnTap was a customized version of FreeBSD 4.x, which has long since been EOL. While I believe NetApp did contribute back some things to the FreeBSD tree way back in the day, I would guess they haven't in many, many years (but that's pure speculation on my part).

Quite the opposite, in fact. NetApp have contributed BHyVe (http://bhyve.org/ / http://wiki.freebsd.org/BHyVe), a full BSD-licensed Hypervisor, in the last year. They make regular contributions to several network card drivers and other low-level code. At least one or two FreeBSD committers are full-time members of NetApp staff.

That's good to hear. It cancels some of my ill-will toward the company due to the ZFS lawsuit.
