Sorry for the maybe dumb question:
I've read everything I found, but i'm still unsure:
given a HP Gen8 with 4x4TB I have one slot left to eqip with an SSD for ZIL-cache (which I really want and need, sync NFS, ESX,... read http://www.freenas.org/blog/zfs-zil-and-slog-demystified/ and http://www.freenas.org/blog/a-compl...-design-part-iii-pools-performance-and-cache/ very carefully)
Is it possible and meaningful to put in - lets say a 500GB SSD and use 50GB for ZIL-cache and the remainder as a volume for storage ?
(storage would be blockchain-data, so if lost it just has to resync a few hours, no need to backup that or keep it on RAIDZx)
The problem with the blockchain-stuff is: it needs highest performance to be comfortable but the data is rather "recoverable waste"..
Thanks for any suggestions :)
