Perpendicular storage.... drool city!

A colleague recently pointed me to Hitachi Global Storage Technologies' lame-as flash animation (hey, we're all geeks, right?) entitled Get Perpendicular. It's all about how disk drive manufacturers can provide us with a phenomenal increase in data capacity by making the bits stand up rather than lie down. According to El Reg we should start to see perpendicular storage available in 2.5in form-factor drives by the end of this year. If you think about the claimed 40Gb per platter capacity then it's no great stretch to imagine having a 4Tb drive in your laptop. I thought I was doing well when I got my new laptop which came with a 60Gb 7200rpm disk. Now imagine a rack full of something similar to these or even these beasties and you start to see why we need something like ZFS to manage it all.
Comments:

Are there any journal publications or conference papers on ZFS that you know of? A prof at my University has a class in going right now where they talk about Advanced OS topics and they hit on various filesystems through the class. A new filesystem would most likely be very interesting topic for him to cover as he hits a wide variety of stuff ranging from papers on Googles Distributed Filesystem to the FFS for Unix( McKusick, Joy, Leffler, and Fabry 1984) to Log-Structured File System(Roseblum and Ousterhout 1991), etc...

If there is anything that you know of on it, I would love to pass it back to him for his class.

I did a quick search and found these hits:

First Workshop on Algorithms and Architectures for Self-Managing Systems (11 June 2003)

where there were two presentations from ZFS folks: Automatic Performance Tuning in ZFS and Existential QOS: ZFS' approach to quality of service

I think ZFS is a great idea and am sure it will be a great success... but when will it ship? I am thinking of the joke about Duke Nukem Forever sometimes when the topic of ZFS is brought up.
