Hybrid flash memory is a multi-plane system design. Which of the following statements is correct? (Multiple choice)

Question

Options

• AGE channels on the service plane for data transmission
• BWhen the GE switching channel fails, the PCIE switching channel can be used as a backup
• CEach plane is redundant to each other, and the control plane can be used for transmission when the
• DThe service plane connects the host IO channel, disk IO channel and GE switching channel

• A
  83% (24)
• B
  14% (4)
• C
  3% (1)

Explanation

In hybrid flash memory multi-plane architecture, the service plane is specifically designed to handle data transmission using GE (Gigabit Ethernet) switching channels (A), and it acts as the central hub connecting the host I/O channel, disk I/O channel, and GE switching channel together (D) - these two statements accurately describe the role and components of the service plane.

Why B is wrong: PCIe switching channels belong to a different plane (typically the control or management plane) and are not interchangeable with GE switching channels on the service plane. The two channel types are not designed as mutual backups.

Why C is wrong: The planes in this architecture are functionally separate, not redundant substitutes for each other. The control plane manages configuration and signaling - it cannot take over data transmission duties from the service plane.

Memory tip: Think of the Service plane as handling all Storage traffic - it Serves data between the host, disks, and the GE network switch. The control plane "controls" but never "carries" user data. Any answer suggesting planes swap roles or that PCIe backs up GE is crossing architectural boundaries that don't exist in this design.
