Actually, they have brought it back, albeit with a different name:

There is also a Nagios plugin:

And of course, I was only joking. NetApp is not a panacea. There are other decent arrays too. I use virtual Oracle ZFS Appliance at home for testing snapshot features. Even running on top of a Linux box, the performance is OK and I have never had any problems with it. I chose it over NetApp simulator because NetApp simulator was limited to 99 GB at the time. Finally, as for the blktrace, I like this brief introduction:
