My current build is 6.0up80.8101.5626 64bit - for some reason it didn't go to the latest when I checked for updates but instead went to this version on both my sans. My raid card is an areca 1680 and is fully up to date. My network cards are Intel CX4 10gbe. I got my config back after restoring two configs.. The first config didn't show my replication disks and stuff so fail over wouldn't start properly but luckily I got it back with a earlier date config..
Also shouldn't my reads be close to full speed but writes should be half of what full speed is due to the replication?
