I'm not really looking to have parallel arrays - just one with a couple<br>
of little drives. And I don't need to share an entire working<br>
filesystem; just daemon config files.<br>
<br>
I don't want to use FC because I don't want to add another breakable<br>
piece (the switch).<br></blockquote><div><br>with only two heads you don't need a switch, just two cards in the drive case.<br><br>double ended SCSI is notoriously unstable....<br><br>DRBD for content and STONITH rig under heartbeat makes a good setup. No special hardware other than an extra nic and maybe serial port connection.<br>
