In distributed storage, the EC mechanism can provide better redundant protection for data. Which of the following descriptions of the EC mechanism are wrong? (Multiple choice)
The correct answer is C. When expanding capacity, if the current hard disk pool can support a larger EC redundancy ratio, D. Node-level security layout has the highest space utilization rate. The hard disk of the faulty node. See the full explanation below for the reasoning.
