Software developer startup Tens Complement has announced:

We’re not quite there yet but we have some exciting products in development. Our version of ZFS for Mac OS X, Z-410 Storage, began external beta testing last week. Expect more announcements soon.

Z-410 Storage will bring the world’s most advanced file system to the world’s most innovative operating system. ZFS and Mac OS X together, at last!

Our foundational release of ZFS for Mac OS X is targeted at early adopters and those who can’t wait to combine the world’s most innovative operating system with the world’s most advanced file system.

The initial beta evaluation program is in progress (thank you to those participating). We hope to have more details about a future beta program soon.

ZFS is a combined file system and logical volume manager designed by Sun Microsystem, featuring data integrity, support for high storage capacities, integration of filesystem and volume management, snapshots and copy-on-write clones, continuous integrity checking, automatic repair, RAID-Z and native NFSv4 ACLs.

Apple originally opened a ZFS project on their Mac OS Forge site in 2007, and it was anticipated that ZFS support would be added to OS X. But in October 2009, Apple announced it was shutting down its ZFS project with the terse statement: “The ZFS project has been discontinued. The mailing list and repository will also be removed shortly.” The reason is presumed to be inability to negotiate agreeable licensing terms with ZFS developer Sun Microsystems and/or ZFS tradmark holder Oracle.

Ten’s Complement LLC was founded by former Apple engineer Don Brady who, according to Wikipedia, was technical lead on the original HFS+ team and worked on Apple’s abandoned internal project to port ZFS. The company’s Z-410 Storage will be targeted at prosumers, and is anticioated to launch around the same time as Apple releases OS X v10.7 Lion.
