Hi Amancio Hasty; On 17-Sep-97 you wrote: > > Microsoft's strategy for server clusters: > > > http://www.microsoft.com/ntserver/info/reliabilityoverview.htm It looks like a very large undertaking on their part. I think I disagree with some of their concepts, but if your intent is to create similar service under FreeBSD, then this is about what we are building. If you want to make our work NT API compliant, forget it :-) Even if their API would have been excellent (which it is not), the restrictions, constrictions, and obstructions would be too much. A DLM is key to these technologies. The you need an RDBMS which understands the sharing concept. A raw/block device is to follow, then a file system. This is the order in which we are going, anyway. One thing i agree with is that clustering is less sexy but much more useful, on many small/medium/large systems than distributed. --- Sincerely Yours, (Sent on 16-Sep-97, 23:15:08 by XF-Mail) Simon Shapiro Atlas Telecom Senior Architect 14355 SW Allen Blvd., Suite 130 Beaverton OR 97005 Shimon@i-Connect.Net Voice: 503.643.5559, Emergency: 503.799.2313
