Designing Cisco Data Center Infrastructure (DCID) — Question 138

An engineer is configuring a Cisco UCS Service Profile template for an environment that will host Windows servers. Some of the servers require access to a Fibre Channel storage network. The design requires the server HBA to send the maximum number of commands to a Fibre Channel disk using a single transmission. Which action must be taken to meet these requirements?

Answer options

• A. Set LUN Queue Depth to 240.
• B. Disable 10 Timeout Retry.
• C. Increase Max Data Field Size to 2096.
• D. Decrease Link Down Timeout to 20,000.

Correct answer: A

Explanation

Setting the LUN Queue Depth to 240 allows for a larger number of commands to be sent simultaneously, meeting the requirement for maximum transmission efficiency. The other options do not directly influence the number of commands that can be sent; disabling timeout settings or adjusting data field sizes does not optimize the queue depth for Fibre Channel communication.
