A Cloud Administrator observes high storage latency for several VMs running on an HPE ProLiant cluster configured with an all-flash vSAN. Using `esxtop` in the disk device view (press 'u'), the administrator reviews the metrics for a vSAN device.

Which statements accurately describe the performance issue based on this output? (Select all that apply.)
A. The network connection to the storage is saturated.
B. The ESXi host's guest VM (GAVG) is experiencing high latency.
C. The storage device itself is responding slowly.
D. The storage device queue (QAVG) is not a significant source of latency.
E. There is high latency within the ESXi kernel's storage stack.
