Robin Harris over at the ZDnet.com Storage Bits blog analyses a new UW-M paper analyzing the fault tolerance claims of ZFS:
“File systems guard all the data in your computer, but most are based on 20-30 year old architectures that put your data at risk with every I/O. The open source ZFS from Sun Oracle claims high data integrity – and now that claim has been tested.
File systems guard all the data in your computer, but most are based on 20-30 year old architectures that put your data at risk with every I/O. The open source ZFS from Sun Oracle claims high data integrity – and now that claim has been tested.
I’m at the USENIX File and Storage Technology FAST conference in Silicon Valley. There is more leading edge storage thinking presented here than any other industry event.
Case in point: End-to-end Data Integrity for File Systems (PDF): A ZFS Case Study by Yupu Zhang, Abhishek Rajimwale, Andrea C. Arpaci-Dusseau and Remzi H. Arpaci-Dusseau of the Computer Sciences Department, University of Wisconsin-Madison. It offers the first rigorous test of ZFS data integrity.”
