completely custom is a bit of a stretch. It was a very heavily modified FreeBSD. And with 8.x 7-mode, it was straight FreeBSD with "ONTAP" essentially loaded as a bunch of userland process'.
- ChuckMcM 10y agoActually no. Shared networking stack code, sure, influenced? possibly as most of the engineers were ex-Sun or ex-SGI, but that was about as far as it went. That changed when Spinnaker was acquired and NetApp ported their Linux stuff to FreeBSD. All Data ONTap code prior to 8 was pretty unique to the NetApp.
- tw04 10y agoThat's... not accurate. There's a reason every time FreeBSD made SMP improvements, ONTAP was quick to follow. Spinnaker != 7-mode, and cDOT took SpinNP and very little else from that codebase. I don't know what history of ONTAP you followed but it's not accurate. There's a reason NetApp has been one of the largest contributors to FreeBSD both in terms of code and monetary support since long before they acquired Spinnaker.
- ChuckMcM 10y agoWell my "history" was that I was the Technical Director and later Senior Technical Director in the ONTap OS group from 2001 to 2006, how about you?
