  1. Have a happy new beer. ;D

  3. I'm building a new Linux home server and i'd like to add an L2ARC and a ZIL, once i paid off all the other components. (A Xeon E3-1240L v3 is rather expensive, but it should be worth it: 4c8t @2GHz in a 20W TDP envelope, sweet!)
  4.  
  5. Here are my questions:
  6. * What capacity should those caches have, >32GB?
  7. * Can i get away with both caches living on partitions of the same SSD? (I know, they would share the SSDs max IOps, but it's a home server at last, not a financial transactions processor.)
  8. * Can those caches be added later, even when there's already some data in the pool(s)?
  9. * To what object are those caches assigned? Is it one global L2ARC / ZIL for all the pools, or is it one cache per pool, or even dataset?
  10. * What about encryption? It would be rather stupid to LUKS-encrypt all the pools, but have their contents in plain text on the caching storage.
