SG0-001 · Question #586
When gathering simple baseline statistics for a storage array, a storage administrator should gather which of the following? (Select TWO).
The correct answer is C. Reads/Writes performed D. Read/Write throughput. When establishing a baseline for a storage array, administrators should collect metrics that reflect typical I/O activity and data transfer rates.

Why each option
When establishing a baseline for a storage array, administrators should collect metrics that reflect typical I/O activity and data transfer rates.
Read/Write errors indicate problems or failures and are not typical baseline usage statistics, but rather critical exceptions to monitor.
The number of switches connected is a configuration detail, not a dynamic performance or usage statistic to include in a storage array baseline.
The number of Reads/Writes performed (often measured as IOPS - I/O operations per second) is a fundamental metric for understanding the workload and performance of a storage array, essential for a baseline.
Read/Write throughput (data transfer rate, e.g., MB/s or GB/s) is crucial for measuring the volume of data being processed by the storage array, providing key performance insights for a baseline.
Port loss of signal counts are indicators of connectivity issues or failures within the SAN fabric, not a normal performance or usage metric for a baseline.
