Right now, I'm managing a "miniature cluster" consisting of three Dell R230 servers. It's strictly a testbed for future deployment on our "real" cluster. That's why I'm experimenting with stuff one shouldn't do on a live system, like deleting nodes...
The live cluster is still relatively small (16 nodes), and will be used for quite a few different applications by our chemists, physicists and engineers. _______________________________________________________________________ Kevin Keane | Systems Architect | University of San Diego ITS | kke...@sandiego.edu Maher Hall, 192 |5998 Alcalá Park | San Diego, CA 92110-2492 | 619.260.6859 *REMEMBER! **No one from IT at USD will ever ask to confirm or supply your password*.
