Nothing might be wrong with this example.
Basically, the collision is when ASM striping undoes hardware striping
to a certain extent.
It may happen if you are unlucky enough to have certain combination of:
- Number of disks in the striped set
- Number of LUNs from that pool
- Stripe sizes
- Extent locations

Hi Alex
When you say stripe collision do you mean hardware stripe larger than ASM or
the other way round?
For example HW RAID 0 stripe 64K and ASM 128K and 1MB, will that cause
collision?
Thanks
