It=E2=80=99s good to see it used in at least a few places. It=E2=80=99s = too good a system to be the only one using it. But I will until = providence completely forces me to do otherwise, which I don=E2=80=99t = anticipate.=20 I=E2=80=99m really lucky to be able to use the system, especially in the = way it was envisioned in the 1980=E2=80=99s. My first knowledge of it = was when I asked Dennis Ritchie what was new. He said that Ken was = playing around with the concept of union directories. Later, during one = of my visits to the Labs, in 1988 I think, Dennis gave me a = demonstration of the system. One problem with most people who haven=E2=80=99t been as fortunate as I = have, is they really just need a single system, not a distributed = system. While Plan 9 makes a better single system for some things than = most OSes, it=E2=80=99s really not supposed to have local disks at all. = It really is designed to be a larger distributed timesharing system. At = Coraid, we had two setups, one in Athens and one in Redwood City, that = supported over 100 users in total. And without a single dedicated system = admin. It was a very part time job, mostly for Erik, but Ian Ennis did = some as well. It was very easy to manage because it was a single = machine. As far as I know, SouthSuite is now the only company both using it as a = development system or shipping software based on Plan 9. Does anyone = know of any others?=20 Different people choose tools for different reasons and to satisfy = different requirements the world places on them. I chose to work in = embedded appliances so I could pick the software I use. The PIX Firewall = was a bit too early for Plan 9=E2=80=94it was not yet released when I = wrote the PIX=E2=80=94but it was very much of the spirit, as was the = Cisco LocalDirector. Soon, we began using the 1995 Plan 9 release and I = have been using it almost exclusively ever since. I use it as the sole = development environment and as the base of the products we ship. In spite of our early success at Coraid with the SR, after the VC = investment the use of Plan 9 became controversial. It=E2=80=99s not what = others use, and in Sand Land (what else can one call Silicon Valley) = that makes people nervous. Over my objections, the company attempted to = move to Open Solaris. It=E2=80=99s a truism that a company that changes = operating system goes out of business, and Coraid, Inc. again proved = that to be true. The reason? A small company can=E2=80=99t afford the = retooling costs to switch to another operating system.=20 But things have turned out well anyway, at least for me and the = traditional Coraid users. Now I have everything from the trademark to = the source code and now offer the Coraid product as a software product = and can support existing Coraid users, both with software updates and = with help getting their hardware fixed or replaced. We are helping all = those folks who bought Coraid gear continue to get value of their = purchase. One fellow sent me a note showing that he=E2=80=99s been up = over 2,000 days without rebooting. There=E2=80=99s never a reason to = fork-lift an SR. I like to think we do a good job, but our performance, efficiency and = low cost is all made possible by the superior system that was developed = by the folks at the Labs from 1987 thru 2002.=20 Brantley=
