Final answer:
Option B: High latency can signify an overworked storage array or host, as it means there is a delay in data packet delivery, which impacts overall system performance.
Step-by-step explanation:
The physical device command latency value that may indicate an overworked array or host is B) High latency. When a storage array or the host system is overworked, they may take longer to respond to commands, thus increasing the latency. Latency is the time taken for a data packet to travel from its source to its destination, which typically should be as low as possible for optimal system performance. High latencies can lead to slower application performance and a less responsive system overall. It's important to monitor latency to ensure that the storage infrastructure is capable of handling the required workload without any significant delays.
High latency may indicate an overworked array or an overworked host. Latency refers to the time it takes for a command to travel from the host to the storage array and receive a response. If the latency is high, it means that the command is taking a long time to execute, which could be due to an overload on either the array or the host.
For example, if the array is overworked and cannot keep up with the incoming commands, it will take longer to process each command, causing higher latency. Similarly, if the host is overburdened with multiple requests, it will take longer to send commands to the array and receive responses, resulting in higher latency.
Therefore, B) High latency is the value that may indicate an overworked array or an overworked host.
