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

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

C.
RAIN overhead accounts for the remaining available GSAN capacity

D.
Checkpoints and logs account for the remaining GSAN capacity
