Which statement describes the ring buffer and how is it used?
A.
The ring buffer is a PCIe card with non-volatile RAM. When data writes are in the ring
buffer, the write is immediately acknowledged. The Block Translation Layer then organizes
the data before it is written to the SSD
B.
Each SSD is divided into many ring buffers, which represent the locations where data is
stored on the SSD
C.
The ring buffer is a circular software storage construct that is used to simulate the
behavior of a track on a hard disk drive
D.
The ring buffer is where writes are queued before they are written lo disk. To protect
against data loss, each write to the ring buffer is captured in a log file located on a persistent
storage device
