I've looked a little but haven't found a solid answer, assuming there is one.
What's better, hardware mirroring or ZFS mirroring? Common practice for us was to use the raid controllers on the Sun x86 servers. Now we've been using ZFS mirroring since U6. Any performance difference? Any other... (3 Replies)

- ARC-1681 PCI-X 8 Port SAS RAID Controller
These controllers support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD using either SAS or SATA II drives.
arcmsr supports management and monitoring of the controller through the bioctl(8) and envstat(8) commands.
Please note, however, that to use some features that require special privileges, such as creating/removing hot-spares, pass-through disks or
RAID volumes will require to have the password disabled in the firmware; otherwise a Permission denied error will be reported by bioctl(8).
When a RAID 1 or 1+0 volume is created, either through the bioctl(8) command or controller's firmware, the volume won't be accessible until
the initialization is done. A way to get access to the sd(4) device that corresponds to that volume without rebooting, is to issue the fol-
lowing command (once the initialization is finished):
$ scsictl scsibus0 scan any any
The arcmsr driver will also report to the kernel log buffer any error that might appear when handling firmware commands, such as used by the
bioctl(8) command.
EVENTS
The arcmsr driver is able to send events to powerd(8) if a volume or any drive connected to the volume is not online. The state-changed
event will be sent to the /etc/powerd/scripts/sensor_drive script when such condition happens.
