The questions arise:
- Does HCI architecture start protecting data as quickly as possible?
- How smart the architecture is to rebuild the lost data and how long it's going to take?
- If the rebuild takes longer, this time window is called risky period. Administrator must hope that there is no other failure occurs during this long rebuild window to ensure FTT and RF requirements.
- Vendors may offer another brute force method of increasing RF / FTT which increases the cost (in the absense of smart architecture).
