Cache?

[gpn005]

Anyone know if caching is already or will be soon enabled like with TrueNAS? I understand the underlying OS supports, as I run TrueNAS already but hoping for that sweet cache goodness, both read and write (whatever fancy names they call them in TrueNAS.).

What you are referring to and calling "cache" are likely SLOG, L2ARC. The problem is, unless you are running 64+GB of ram, you will not see any appreciable performance gains from using those functionalities. You will be much better off investing in RAM on the server as TrueNAS ZFS uses RAM for caching anyway and is a much more effective solution. What you are seeking is more a function of Unraid and while you can set up SSD "caching" as a new dev in TrueNAS, you would have been better off investing in RAM than a cache SSD.

Appreciate the reply. I had some old 256GB SATA SSDs not in use so was just thinking of using those like I did with my other TrueNAS. Was just curious if the "cache-like"/write-log ZFS functions L2ARC and SLOG would be exposed in the HexOS UI. I understand it's supposed to be simplified so totally understand the decision not to this early if that is the case. I'm not a crazy big NAS user where any cache makes a huge difference, outside of maybe some repeated backups so it's more for nerdy fun than anything else. I've had to move around some RAM for an Xmas gift so won't be overdoing my RAM beyond 32GB which is already overkill for my purposes.

Cheers!
