For de-duplication to perform well you need to be able to fit the de-dup table in memory. Is a good rule-of-thumb for needed RAM Size=(pool capacity/avg block size)*270 bytes? Or perhaps it's Size/expected_dedup_ratio?
And if you limit de-dup to certain datasets in the pool, how would this calculation change? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
