I was wondering if there were work done in the area of zfs configuration running out of 100% SSD disks.
L2ARC and ZIL have been designed as a way to improve long seek times/latencies of rotational disks. now if we use only SSD (F5100 or F20) as back end drives for zfs, we should not need those additional log/cache mechanisms..or at least algorithms managing those caches might need improvement in the same way, I guess, when running an OS on a SSD boot disk, should we still need the same memory swapping mechanisms as we do today, considering that in that case, the swap device is (nearly) as fast as memory itself. To some extension, log journals found in DB would also not be relevant anymore? tia, selim
