An EMC Avamar customer’s Gen-1 system with 4 TB of GSAN capacity has reached
read-only threshold. The customer indicates that the deduplicated backup data accounts for
approximately 3.5 TB. What is the most likely cause for the read-only threshold being
reached?

A.
Combination of system overhead, logs, and checkpoints account for the remaining
GSAN capacity

B.
RAIN overhead accounts for the remaining available GSAN capacity

C.
Checkpoints and logs account for the remaining GSAN capacity

D.
Deduplication rate is less than expected, accounting for the remaining GSAN
capacity
