Memoirs: SiCortex (background)

For a long time, especially before our daughter was born, my wife and I were fairly avid hikers. Sometimes we would hike by ourselves, sometimes with the Appalachian Mountain Club. As it turns out, one of our favorite AMC group leaders was an early employee at SiCortex. During my period of discontent at Revivio, we got to talking about . . .

Memoirs: Last Days at EMC, and Revivio

After MPFS shipped at EMC, I left the project and started working in more of a research role again. My main project was a hierarchically distributed block cache, which I called C3D for no reason I can remember. A surprising amount of detail, even down to packet formats and such translated into legalese, is in the main patent . . .

Memoirs: MPFS at EMC

The MPFS project at EMC wasn't quite the most "impactful" of my career (that was probably REACT/ATF) and it didn't quite gain me the most recognition/notoriety (that was probably Gluster) but it might have been second in both regards. It was also one of the most unpleasant projects of my career, mostly because it was so deeply infected with . . .

Memoirs: Conley and EMC

When I was becoming dissatisfied at Mango in 1998, my friend Mike - he of the Dead Kennedys t-shirt at Clam, who had introduced me to Mango and would later hire me at Revivio - introduced me to the founder of Conley. I never actually found out where the name "Conley" came from, but it was an interesting little company. At that time they were . . .

Memoirs: Mango

After Dolphin, my next gig was at Mangosoft. My wife still jokes that I moved up the evolutionary scale when I went from Clam to Dolphin, then back down when I went to Mango. It was the second most unfortunate name for a company that I worked for, and if you pronounce it as man-go-soft it's even worse.

Mango's thing was a distributed . . .

Memoirs: From Clam to Dolphin

Word must have gotten around about the "success" of the 7135/REACT project, because we started getting requests to do similar things for other storage vendors. The first of these was Clariion, before it got slurped up by EMC. They wanted essentially the same functionality for their disk arrays, under the name ATF (Automatic Transparent . . .

Memoirs: CLaM part 1

In 1992, I went to interview at a little company in the Lechmere section of Cambridge, with the rather unconventional name of CLaM Associates. The odd capitalization is because it stood for Comeau, Linscott, and Miller. Les Comeau was an IBM old-timer, having been the authors of VM/370. (Fun fact: shortly after I started working there, I . . .
