Avoid 0_0 while mirroring

Can someone explain to me, why i have to avoid mirroring over DPE or DAE-OS enclosure 0_0 ?

Thanks a lot...

Because on a sudden power loss the disks in the DPE/DAE are kept up longer by the SPS to de-stage write cache to the vault

Disks 0_0 (DPE) have SPS protected, while 0_1, 0_2... (DAEs) haven't. The data would be inconsistent if there were a power outage.
