Which three factors should you consider before you install an E2860 in a data center? (Choose three.)
Current Draw: It is important to consider the electrical current draw of the E2860 to ensure that the data center power infrastructure can support it without overloading circuits.
Heat Dissipation: The heat generated by the E2860 needs to be accounted for in the data center's cooling design. Proper heat dissipation mechanisms must be in place to prevent overheating.
Ambient Temperatures: The operating environment's temperature should be within the specified range for the E2860 to function correctly and reliably. Ensuring that the ambient temperatures are controlled is crucial for optimal performance and longevity of the equipment.

You help a customer diagnose a performance issue on an E-Series storage system. You decide to measure the amount of data that is being handled over the span of an hour.
In this scenario, what are you measuring?
Definition of Throughput: Throughput refers to the amount of data transferred from or to the storage system over a specific period. It is measured in units such as MB/s or GB/s.
Relevance to Performance Diagnosis: When diagnosing performance issues on an E-Series storage system, measuring throughput over an hour helps determine the data handling capacity of the system. This metric can reveal whether the system is processing data efficiently or if there are bottlenecks.
Methodology: Tools within the SANtricity System Manager can be used to monitor and log throughput, providing insights into the performance characteristics and potential areas needing optimization.

A customer has launched a data analytics initiative and has been transferring old data into the new data lake. The customer has discovered some data read errors during the transfer process.
In this scenario, how should the customer have avoided these data integrity issues?
Data integrity issues can often be prevented by ensuring that mechanisms for data assurance and media scanning are activated.
Data Assurance (DA) is a feature that verifies the integrity of the data as it is read from or written to the storage system, detecting and correcting errors.
Media scan is a background process that checks the entire disk surface for errors and corrects any found before they cause data integrity issues.
Together, these features ensure ongoing data integrity by preemptively identifying and fixing potential issues.

What is represented by the Headroom graph on the SANtricity System Manager performance tab?
The Headroom graph in SANtricity System Manager shows the remaining performance capability of the physical objects (e.g., disks, SSDs) in the storage system.
This helps in understanding how much additional load the system can handle before reaching its performance limits.
