Cisco Exam 300-610 Topic 5 Question 79 Discussion

Actual exam question for Cisco's 300-610 exam
Question #: 79
Topic #: 5
[All 300-610 Questions]

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 conned 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?

Show Suggested Answer Hide Answer
Suggested Answer: D

When restrictions on oversubscription ratios are disabled, the bandwidth allocation among the shared ports is proportionate to the configured speed. (If the configured speed is auto, then bandwidth is allocated assuming a speed of 4 Gbps.) For example, if you have three shared ports configured at 1, 2, and 4 Gbps, then the allocated bandwidth ratio is 1:2:4. In Cisco SAN-OS Release 3.0 and later (or when restrictions on oversubscription ratios are enabled), port bandwidths are allocated in equal proportions, regardless of port speed, so, the bandwidth allocation for the same three ports mentioned in the example would be 1:1:1.

I'm just hoping the exam doesn't ask me to calculate the total port count or something. That would be like asking a chef to solve differential equations.

I know right! Calculating port counts can be tricky, but with enough practice, you'll get the hang of it.

B) UCS: four-port Port Channel from each IOM to each fabric interconnect. Storage: four-port SAN-PortChannel from each SAN controller to each fabric interconnect.

Option D seems a bit odd with the 'back-to-back' PortChannel. I'm not sure I've seen that configuration before, but it could be an interesting way to approach the problem.

True, it's always important to understand the reasoning behind design choices in complex environments like data centers.

Maybe the engineer has a specific reason for choosing that setup, it would be interesting to know the rationale behind it.

I agree, the back-to-back PortChannel configuration is not very common in data center environments.

Option D does seem a bit unusual, but it could be a unique solution to consider.

I'm not sure, but option B also looks like a good choice with the four-poll Port Channel from each IOM to each fabric interconnect.

I agree with Lai. Option A seems like the most reliable choice for the storage connectivity strategy.

I think the engineer should choose option A because it provides redundancy and load balancing.

Haha, what is this, a Cisco networking exam? I bet the right answer is whatever maximizes the number of ports and PortChannels. More is always better, right?

Definitely, more ports and PortChannels usually mean better performance and redundancy.

I'm a little skeptical about the four-port SAN-PortChannel in Option B. Wouldn't that be overkill for a direct-attach Fibre Channel storage array?
