Not too much IOPS are expected, and some could be mitigated with L2ARC with only metadata cached, I suppose. Two usage schemes are file server for big files (mostly cold storage) and backup/surveillance server (constant stream writes, occasional random reads) Any hints? Thanks! -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
