Bryan Cantrill of Joyent presents Manta, an internet-facing object store that lets you run compute directly on the data. The talk is peppered with ZFS history and Cantrill's trademark commentary on the industry.
HN recommends Cantrill talks generally for their mix of industry history, technical depth and entertaining delivery, and this one is a favorite for storage and data integrity threads.

If you have corruption in RAID 1 how do you know which copy is good? On a slight tangent ZFS will checksum data and store that checksum in the block pointer (i.e. not with the data itself) so it can tell which of the copies is correct. The same extends to RAID 5 and RAID 6, although with RAID 6 you can intelligently work out which block might be bad. However that is assuming the block devices are returning consistent data and you are the one talking to the block devices. If the disks were sat behind a hardware RAID controller and the controller was the one you'd be hard pressed to identify the source of the data corruption. The checksumming in ZFS comes to the rescue here again. I recommend checking out this video [1] from Bryan Cantrill. It's about Joyent's object store Manta but features a fair bit of ZFS history. Also it features the usual rant level that one can come to expect from a Bryan Cantrill talk which I quite enjoy. There are plenty of other videos available on ZFS. [1] this video
Bryan Cantrill says it best, I think[1]: "If you had to explain the Nazis to someone who had never heard of WWII but was an oracle customer, there's a very good chance you would actually explain the Nazis as an Oracle allegory." There are more choice quotes in someone else's HN comment about Bryan Cantrill on Oracle.[2] I highly recommend any talk you can find of Bryan Cantrill. A wonderful mix of industry history and great delivery. 1: this video 2: [LINK]
You might enjoy this talk by Bryan Cantrill, where he describes the Oracle acquisition of Sun: [LINK] > "what you think of Oracle is even truer than you think it is. There has been no entity in human history with less complexity or nuance to it than Oracle" > "this company is about one man and his alter ego and what he wants to inflict upon humanity" Edit: And how could I forget this: this video > "and then, the Nazis invaded" > "for a while I tried to not go to Nazi allegory when talking about Oracle but I actually think that it does a dis-service to not go to Nazi allegory because if I don't use Nazi allegory when referring to Oracle there's some critical understanding that I have left on the table"
If anyone's interested in a presentation introduction to Manta (presumably similar to the one you saw), you may want to check out my FutureStack presentation from last year.[1] And if you have 90 minutes to kill and are in the mood for the true origin story of Manta, see my video from NYC DevOps in January.[2] [1] [LINK] [2] this video
Bryan Cantrill expresses this[1] in a manner I certainly agree with. Software that is designed/ intended to be reliable should not go through large periods of instability only to be written off as "prepubescence". [1] this video
