I've just started testing a setup with an areca arc-1680 sas card and an external sas-cabinet. It currently has a zpool with ten 1 TB-drives in raidz2. It may grow to a two-digit TB system if the testing goes fine. It will nfs-share the partitions to my FreeBSD webservers. I'm using nfs v.3 and tcp with a read- and write-size at 32768. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare
