Drobo Pro, Mac OS X, and Firewire

Aargh.

I spent parts of several days diagnosing a problem connect a Mac XServe and a Drobo Pro. The Mac is running OS X Server, Snow Leopard, and the Drobo is up to date on firmware.

The problem is that there's an error with Fast Start firewire packets. The problem occurs when we're using FW 800, but not USB. I swapped cable, ports, etc; problem remained unsolved. I tried with a MacBook Pro (no error).

Now, after several days, Apple admits this is a known issue. It's happened with at least two different types of Mac hardware, and may be related to high amounts of RAM (we have 32GB in the XServe).

What's frustrating is that there is no public information about this. This is not an issue I could have known about, and Apple is not informing people inside enterprise tech support properly. This has also not been put in Apple's bugtracker (and AFAIK, Drobo doesn't have a public bugtracker).

Maybe, just maybe, someone will find this post and save some time. I can only hope.

Obviously, I will post more info if it becomes available. For now, as great as the Drobo is (and it was pretty much effortless to set up), it's not working with Firewire 800.
