The idea of perhaps caching writes onto a RAID-0 system I meant caching onto an arbitrary volume, probably using a simple journalling "filesystem". Personally, a RAID 1 volume would be my choice, but the type of target volume would have no bearing on the implementation. RAID 1 writes are slower than RAM (duh!) but faster than RAID 5... and they don't have the reliability issues associated with writeback RAM cache (duh!). > and then transferring them is possible. But it sounds to that such a > system would be hard to setup. Such is what I thought... but I still had to ask. :-) Eddy --------------------------------------------------------------------------- Brotsman & Dreger, Inc.
