Splitting an SSD between log and cache generally isn't a very performant option. Devices that make good cache devices may not be good logs. With SmartOS running KVM, there is a big gain from log devices, but not much from a cache. On this subject: What is the current thinking on the need to mirror slog and/or L2ARC devices? There never has been any need to mirror L2ARC device, you might get a small performance gain reading from a mirror. Now logs are recoverable, there is little benefit from mirroring log devices. Cheers, Ian.Logs are now recoverable? This is news to me! Is this only in Illumos ZFS, or is it available in OpenZFS on Linux as well?
Typo! s/recoverable/removable/ Cheers, Ian. ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
