DownSouth - another tidbit on NTAP - a good friend of mine who was also a CPQ investor sold his CPQ holding in January of 1999 and put it into NTAP - he was confident enough that he sent me a note with the value of the holdings at that point, and a (for him) unusual "I'll be back in 2 years to remind you" comment. Needless to say, CPQ is at half of what it was then, and NTAP? Up a bit I would say, I think he has an 8-bagger. I don't yet know enough about SUNW's architecture to know what mechanism they use for snapshot capability. There are a couple of different approaches being used, with the highest performance (and most reliable) versions using journaling mechanisms taken from the database world. There are several advantages to a journal / checkpoint approach. The snapshot is the "real" data (i.e. the state of the underlying data) so there is less management when a large transfer (such as a backup) is the target of the snapshot. Reliable queues provide for transaction integrity and coherent views of the current state of the data. The differences in how people are doing that reflect tradeoffs in the time to recover current state in the event of a system failure versus performance degradation when there is no failure, and the flexibility of the allocation of resources when a snapshot is open.
