L2ARC (Read Cache)

L2ARC, or level 2 Adaptive Read Cache, is the read cache for ZFS. In this dialog you can select the devices to be used for read caching.

ZIL, or ZFS Intent Log, is the write cache for ZFS. In this dialog you can select the devices to be used for write caching. You must select two devices that can be mirrored together for data integrity in the case that one of the drives fail.
