Designing Cisco Data Center Infrastructure (DCID) — Question 101
An engineer must design the compute portion of a data center environment. The environment includes:
• direct-attach Fibre Channel storage array with four 32 G Fibre Channel ports per controller
• Cisco UCS B-series servers equipped with Cisco UCS IOM 2408 Fabric Extenders
• Cisco 6454 Fabric Interconnects
The fabric interconnects connect to the LAN via 100G ports, the SAN via 32 G Fibre Channel ports, and the IOM 2408 via 10 G ports. Which storage connectivity strategy must the engineer choose?
Answer options
- A. UCS: Qty four 802.1q trunks from each IOM to each fabric interconnect Storage: Qty two Fibre Channel links from each SAN controller to each fabric interconnect
- B. UCS: four-port back-to-back PortChannel between IOM and fabric interconnect Storage: two-port SAN-PortChannel from each SAN controller to each fabric interconnect
- C. UCS: two-port PortChannel from each IOM to each fabric interconnect Storage: Qty four Fibre Channel links from each SAN controller to each fabric interconnect
- D. UCS: four-port PortChannel from each IOM to each fabric interconnect Storage: four-port SAN-PortChannel from each SAN controller to each fabric interconnect
Correct answer: C
Explanation
The correct answer is C, as it provides the required two-port PortChannel from each IOM to each fabric interconnect and four Fibre Channel links from each SAN controller to each fabric interconnect, aligning with the system's design specifications. Options A and B do not meet the connectivity requirements for the Fibre Channel links, while option D specifies a four-port PortChannel that does not match the two-port requirement for the IOM to fabric interconnect connection.
