Compute Design

An engineer is configuring a Cisco UCS Service Profile template for an environment that will host Windows servers. Some 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 in a single transmission. Which action is required to meet these requirements?

  • 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.
Explanation

In Cisco UCS, LUN Queue Depth specifies the number of commands an HBA can send and receive in a single transmission for each LUN. Setting it to 240 meets the requirement to maximize the command count sent to the Fibre Channel disk per transmission.
