A customer reports disk IOPS have been below the SLA for the IaaS. An administrator adds more capacity to the storage infrastructure behind the IaaS offering, but
notices the I/O performance does not improve immediately after adding storage capacity. Which of the following explains why this occurred?
A. New storage does not become available immediately after configuring
B. The customer may have done heavy performance testing to confirm the new infrastructure’s ability
C. The cloud monitoring system needs to recognize the new storage before the hosts can write to it
D. The data needs to redistribute among the new storage, causing more back-end I/O
