Greetings all, I just had a brainstorm... I was thinking about database servers with several spindles in a RAID 5 array. Write performance is inherently disappointing -- which may or may not be an issue. Would it be worth the trouble to design an "intermediate" cache, whereby data are quickly written to a spool disk, then to the final destination? Sort of like softwares that cache CDROMs on HDD... My gut feel is that this would be more trouble than it's worth, would not net any overall performance*reliability (expressed as a product) gain, and that one might actually realize a p*r decrease. Comments, flames, larts, and funny stares appreciated. Eddy --------------------------------------------------------------------------- Brotsman & Dreger, Inc.
