 The L2ARC has been moved to the JBOD, so that each OSS server's partner can also see the device.  The ZIL has been removed altogether, which leaves room for one additional HDD over the first-generation design; the extra HDD together with the larger per-disk HDD capacity makes each second-generation pool 66% larger than the previous generation. The L2ARC has been moved to the JBOD, so that each OSS server's partner can also see the device.  The ZIL has been removed altogether, which leaves room for one additional HDD over the first-generation design; the extra HDD together with the larger per-disk HDD capacity makes each second-generation pool 66% larger than the previous generation.
