Hello Kevin, to avoid going into all details I am trying to find the critical one(s): I am a bit afraid you expect NFS- or SMBFS-like behaviour from Coda concerning latency.

The throughput on an open file is exactly that of the local filesystem - because the file *is* local, in the cache. But a close() after writing and open() before reading will be very time-consuming. I haven't tried Coda on 100Mbit network but I can't expect over 7Mbyte/sec anyway, so when you start a playback of a 2000M file from Coda, you will have to wait 5 minutes at least (the first time). Similarly with ending a recording. (btw if you have replicated servers, the close() time will grow proportionally to replication count - as multicasting is not used by current Coda) And of course you will have to have lots of cache space. Another note - I am unsure what do you mean with "backup", Coda might be right or wrong depending on your expectations. Replication is not really backup :) Otherwise at first glance your plans seem doable! (don't think anybody ever tried to share the client cache - and corresponding metadata - between two OSs) Regards, -- IvanReceived on 2002-10-15 14:25:57
