Question
You want to monitor and manage storage system parameters such as temperature, voltage, current, and fan speeds over Ethernet.
In this scenario, which component is a system-independent resource in the storage system that helps you accomplish this task?
A. USB port
B. SP port
C. SFP+ port
D. serial port
Answer
B. SP port
Explanation
In NetApp storage systems, the SP or Service Processor port is a dedicated Ethernet port that functions as an independent component for monitoring and managing key system parameters over the network, without relying on the storage controllers or other components. The SP port connects to an internal Service Processor module.
The Service Processor continuously monitors hardware sensors for environmental and operational conditions like:
- Temperature
- Power supply voltage
- Current draw
- Cooling fan speeds
This monitoring happens independently of the storage OS and controllers. If any measured values exceed normal ranges, the SP can proactively alert administrators over the network connection through the SP port. Administrators can also connect to the SP port’s IP address to check system health, view logs, and perform some management functions separate from the primary storage interfaces.
So in summary, the SP port and Service Processor form an independent, always-on subsystem within NetApp appliances for monitoring critical environmental variables over Ethernet, making B the correct answer. The other ports mentioned are for data I/O or external connections, not for this specialized monitoring role.
