We are in the processes of planning for the installation of a large file server that will be be running AFS, and was wondering about using AFS on the Cray, SGI, Sun, VAX, IBM, Stardent, and other computers. Are there particular headaches that can be avoided by knowing of past mistakes? Is there public domain versions of the software available, or should we tell management to come up with the money to buy it. Are there third party vendors, and if so who are they? Any parting shots...er...comments? Thanks & B Cing U Buck P.S. Email responses will be collected, munged, and posted. -- Loren Buchanan (buck@caligula.nrl.navy.mil) | #include <standard.disclaimer> NRL Code 5842, 4555 Overlook Ave. | #include <computer.graphics> Washington, DC 20375 (202) 767-3884 | #include <electronic.music> Phone tag, America's fastest growing business sport.

If you're asking about PD versions of AFS, the answer is that you need to get your management to purchase the necessary software from Transarc (they're located in Pittsburgh).

Here is my response document in regards to my AFS questions from last week. With the exception of some minor editing to remove some noise here are the responses: From: zebr360@ut-emx.uucp (Jerry Heyman) In article <337@ra.nrl-cmf.UUCP> buck@caligula.nrl.navy.mil (Loren Buchanan) writes: >We are in the processes of planning for the installation of a large file >server that will be be running AFS, and was wondering about using AFS on >the Cray, SGI, Sun, VAX, IBM, Stardent, and other computers. > >Are there particular headaches that can be avoided by knowing of past mistakes?

The company that is selling AFS now is called Transarc. [Transarc was founded and is run by Al Spector -- the creator of AFS, Camalot, and many other goodies from CMU.] You can get phone, address, email from the whois server on nic.ddn.mil: my info from them is at work right now. I don't know if CMU is distributed sources to AFS anymore. There might be an exclusive agreement between them and Transarc. If you have the money (and it is a lot) I would pay money to Transarc for the support. There are some things that really need to be improved in AFS that Transarc is working on (like being able to restore a single file rather than a whole volume.) --mark Thanks for the information. Daniel S. Nydick of the Pittsburgh Supercomputing Center is working on AFS for Unicos Crays. I do not know if this port will be made available to others.
