Hello,
My main purpose of running freeNAS is to use iSCSI for a high availability cluster.
Which means reliability is the first priority (which is why the RAID 10 config)
I have a dedicated NAS box with 16GB RAM and quad core processor
1 x SSD (I have installed FreeNAS on this)
4 x 2TB SATA Hard disks with hardware raid (I have configured RAID 10 using the on-board RAID controller)
Now my question!
1) When I access Freenas using the GUI, I click on storage -> volumes -> view disks -> I see 4 disks!

I was under the impression that a hardware RAID would only show 1 Disk to the operating system. Am I correct?
Is there something wrong with the RAID controller?
2) Is it better to do Hardware raid or software raid?
I believe I could just disable the hardware raid and use the ZFS volume option and could achieve a RAID 10 equivalent solution? If yes how exactly would I do this? as the GUI only shows mirrored or striped option - I don't see a mirrored+ striped option in the ZFS volume manager.
3) Which is easier in terms of disaster recovery?
In case the hard disk fails, is the software RAID process to replace a failed hard disk easy?
Thanks,
