Which of the following are hot-pluggable devices in a storage array? (Select TWO)

An HBA (Host Bus Adapter) is generally a critical component that often requires a system shutdown to be installed or replaced, as it typically interfaces directly with the server's bus and operating system.

Power supplies in modern storage arrays are typically hot-pluggable, allowing for replacement or upgrade without interrupting the array's operation, ensuring continuous power delivery.

Disks (drives) are designed to be hot-pluggable in storage arrays, enabling replacement of failed drives or addition of new capacity while the array remains online and accessible.

A drive chassis is the main enclosure housing multiple drives and other components; replacing or adding a chassis typically involves significant system reconfiguration and usually requires a shutdown.

ISL (Inter-Switch Link) refers to the fiber optic cables connecting Fibre Channel switches, not a hot-pluggable device within a storage array itself.
