Which two statements describe ONTAP NVRAM? (Choose two.)
ONTAP NVRAM stores uncommitted writes, ensuring data integrity against sudden power loss by maintaining a log of these writes until they are safely committed to disk. It is also battery backed, providing power to preserve the data in the event of a power failure.
When a Host or Client writes to a storage system, the system simultaneously writes to the Memory buffer (System RAM) and LOGs the write to battery-backed NVRAM When the NVRAM is half full (at 50%) and (or 10 secs has passed for a CP to occur) now it is time to commit the data that is in the memory buffer (System RAM) to the drive NVMRAM is only for logging uncommited writes. it never actually writes to disk to disk. Only the memory buffer (system RAM) is used as an cache. NVRAM is battery-backed for sure.
