The system's disk bays are designed to permit disk drive removal and insertion while the system is powered on. Hot-plug technology significantly increases the system's serviceability and availability, by providing the ability to:
Add additional hardware dynamically to enable the system to handle an increasingly larger work load, perform load balancing, and improve performance of a running system.
Remove/replace faulty hardware with minimal system service disruption.
