NetApp Threatens Sellers of Appliances Running ZFS
eldavojohn writes "ZFS is licensed under the CDDL and is considered to be open source, but NetApp is sending threatening legal letters to startups who look to offer ZFS on NAS appliances. This assault on Coraid has a few people worried about the future of ZFS as NetApp rears its ugly head yet again. The CEO of Coraid replied to NetApp's demands, saying, 'We made the decision to suspend shipment after receiving a legal threat letter from NetApp Inc., suggesting that the open-source ZFS file system planned for inclusion with our EtherDrive Z-Series infringes NetApp patents.' Will NetApp effectively destroy any future ZFS might have enjoyed?"
We need a site to organise boycotts of companies that abuse the patent, trademark, or copyright system. Not everyone would need to sign on to all of them, but anyone should be able to post a call and explain their reasoning. If we got enough techies onto it who would use it at work, it could have some muscle.
For every problem, there is at least one solution that is simple, neat, and wrong.
So the story goes, this dates back to some interns who worked at NetApp and then went to Sun and perhaps influenced ZFS.
The technology in WAFL is that of a pointer-based filesystem - which itself is pretty ingenious and is only now being feature-emulated (ZFS, BRTFS, etc).
One can say what they want of Netapp's pricing, but the technology is extremely solid and simple to operate compared to managing Linux or Solaris boxes running a filesystem as a NAS; the snapshots are without I/O penalty and you can take a lot of them, the clustering is *FAR* simpler than anything happening on general-purpose OSes, the support for protocols is industry-leading (FCoE, NFSv4, SMB 2.0 - they have a codeshare w/ Microsoft and do not use a reverse-engineered Samba implementation or run any kind of Windows storage server like competitors do).
ZFS has a lot of promise, but does not have nearly the performance that WAFL does (considering RAID-DP versus ZFS RAID6) and has only some of the feature set of mirroring, snapshot vaulting, filesystem and file cloning, WORM-compliance, etc. Companies don't want to bet their business on a science project of roll-your-own NAS which doesn't have the feature set the Netapps do, and no serious competitor (eg a company with the ability to financially stand behind the product) in the enterprise space has anything like the feature set.
I work for a systems integrator and I've messed with hundreds of Netapps, Sun and Linux appliances, and competitors over the years. I use ZFS at home because I can't afford a Netapp (and wouldn't want to pay the electricity bill if I could!) but if I ran an IT department I'd put my data on a Netapp FAS over a ZFS appliance any day.
