How ScaleIO disitributes data between nodes?

Hi,

I have, for example, 5 ScaleIO nodes with 6 disks in every node. Each disk is configured as RAID0. All nodes are in one protection domain, all disks are in one storage pool.

How many disk can I lose in every node before my data is lost?

    ScaleIO protects data across nodes (distributed mirror) , so you can lose all disks on the same node without impact availability,but if you loose simultaneously 1 disk in one node and another disk on a different node, you may lose some data. Somewhat similar as a RAID 1 on a storage.

    So I must configure RAID1 on each node to aviod data loss?
