donburkard Posted July 10, 2008 Share Posted July 10, 2008 Maybe this is a dumb question but can someone explain the cache drive thing to me. What size should it be?, what is the purpose of it?, how does it work? etc, etc. ill take any info you can throw at me. Thanks Link to comment
Billped Posted July 10, 2008 Share Posted July 10, 2008 Size is up to you. It needn't be big but remember that the small drives tend to be old drives which, in turn, tend to be slow drives. Purpose is to have a drive that is not associated with parity thus it will not be slowed by parity calculations making it 2x-3x the speed of writing to parity protected drives. You can copy fast to the cache drive then the contents will be automatically copied to the parity protected drives late at night. Bill Link to comment
RobJ Posted July 10, 2008 Share Posted July 10, 2008 See the FAQ at http://lime-technology.com/wiki/index.php?title=FAQ#Cache_Drive for a bit more info, but Bill basically covered it. Link to comment
SSD Posted July 10, 2008 Share Posted July 10, 2008 What's the most data that you would typically copy to your array in a day? Add 50%. Your cache drive should be at least that big. 40g is likely plenty for many users. Mine is 250G just because I had a spare 250G drive. I never come close to filling it up. Link to comment
