Spin up 3 ISCSI Targets. (Base # needed for Expandable Parity disk in Windows Storage Spaces)
(I use FreeBSD / ZFS / ZVOLS)
(Could be 3 targets on same node, but for true HA, I use 3 physical Nodes (In this example, one target per node))
(Engineer your HW and disk layout as needed to meet your performance / robustness requirements)
(HW redundant everything – Power, Nics, Switches, etc…)
(Engineer your networking correctly (MPIO vs LAGG/Teaming))
Add the 3 Targets to ONE node of your Failover Cluster Nodes
(Windows Hyper-V Server 2012 R2)(Need Active Directory/M$ DNS for Failover Cluster):
(I use old school Computer Manager from remote PC to mirror the OS Volume to two spindles on these heads (keep closing and opening))
(I tried with FreeBSD10/Samba 4 as DC/DNS – Didn’t work out of the box for me (might have been able to if I manually created all SVR records etc)…ANYWAYS)
(Modify/Repeat as needed for 3 targets):

Get into Failover Cluster Manager
Select your cluster -> Storage
Right click Pools -> Add Pool
Select your three ISCSI Target disks – Create pool
Create a Parity Disk (Expandable in future) on that pool.
Create a Volume on that disk
(IN FCM): go to your Cluster -> Storage -> Disks
Add it to Cluster Shared Volumes
Celebrate!
