- Revisit of embedded ZFS (tiny ZFS was a discussion back in the Sun days)
I am afraid that by the time someone manages to develop a non-RAM-hungry version of ZFS, it would be irrelevant because the "small" devices in the field would have dozens of gigabytes ;) Now, we've had servers running quite well with early Solaris 10 releases that had 1-2Gb RAM, many boxes with 4Gb RAM are quite happy with that as well. This is roughly the memory resources of a smartphone today. The things which may "suck" are in the area of performance, and the memory footprint of ZFS caching (for it to be effective and responsive) vs. the storage size. The said servers had about 4*73Gb drives... boxes with 16Gb RAM and some 8Tb of storage might and did perform worse on a number of occasions and workloads - simply because many jobs needed the metadata to be cached, or went back to disk to refetch it again if it fell out of L2ARC. And I don't think this is fundamentally changeable, not very quickly at least. Maybe I am too pessimistic though :) //Jim ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
