Diagnose and resolve latency, IOPS, or throughput bottlenecks in Pure/Dell arrays using Pure1, Dell CloudIQ, or array-native CLI tools (e.g., purearray, symcli).
Troubleshoot host connectivity issues (e.g., HBA failures, SAN fabric congestion, multipathing misconfigurations).
Analyze storage-related performance degradations in trading databases (e.g., Kafka, Oracle Exadata, MongoDB) and recommend fixes (e.g., volume QoS adjustments, tiering policies).
