ZFS ZIL + L2ARC SSD Setup
...enabled? - For the tank, on the 8port Areca, do I need a battery backup on that controller aswell or will the ZIL suffice to assure correct data? - Does it make sense to use HW RAID10 on the storage controller or would I get better performance out of JBOD + ZFS RAIDZ2? Best Regards, Felix Buenemann

l2arc current usage (population size)
Hello, How do you tell how much of your l2arc is populated? I''ve been looking for a while now, can''t seem to find it. Must be easy, as this blog entry shows it over time: http://blogs.sun.com/brendan/entry/l2arc_screenshots And follow up, can you tell how much of each data set is in the arc or l2arc? -- This message posted from opensolaris.org
