   - If you follow the advice on ECC memory then the processor must support ECC memory (not all do). All Xeon CPUs do, as do many Pentiums, Celerons, and Core i3 CPUs. No Core i5 or Core i7 CPUs support ECC.   - If you follow the advice on ECC memory then the processor must support ECC memory (not all do).

   - Use enough HDDs in your system so you can employ some sort of redundancy within the zpool/s and the vdev/s. If you aim for a minimum of 4 this will allow RAIDZ2 (ooooh yummy).   - Use enough HDDs in your system so you can employ some sort of redundancy within the zpool/s and the vdev/s.
