I'm excited by ZFS software raid, particularly with the dual parity facility.
Now, I use Solaris 8 during my day job (I'm a developer), and I have a TwinHead SParc5 clone in the cupboard, and I routinely install Linux (and sometimes *BSD), but I'm by no means a Solaris admin. So some questions: 1) Is Solaris getting better at handling controller and disk quirks so that SATA2 disks will generally write-through as they are told? 2) If I configure disks to write through, but normally have write-back in the OS disk cache, and I create a loopback device on a file, and I use the device in direct IO mode and force flushes to it, do those flushes write through to the platter? (Say I'm running Sybase in a Linux container and I'm very old-fashioned in the way that I install Sybase) I'm looking at a picture of a new AMD nForce motherboard, and it has 6-off 300meg SATA ports. And I'm thinking this looks like a fine home server platform, especially if the iSCSI target is easy to administer and reasonably performant on plain gig-e.
