Dell EMC Specialist – Systems Administrator, Unity — Question 15

A customer has an OLTP application running on a host accessing Dell EMC Unity Block storage. The application performance is experiencing CPU bottlenecks caused by iSCSI workloads. As a result, you are recommending the addition of an expansion module with an iSCSI Offload engine to the Unity system.
Which Unity expansion module is recommended?

Answer options

• A. 2-port 10 GB/s iSCSI module with SFP
• B. 4-port 1 GB/s GbaseT module RJ45
• C. 4-port 10 GB/s iSCSI module with SFP
• D. 4-port 10 GB/s GbaseT module RJ45

Correct answer: B

Explanation

The correct answer is B, the 4-port 1 GB/s GbaseT module RJ45, which is specifically designed to handle the iSCSI workloads without straining the CPU. The other options either offer higher speeds that the current infrastructure may not support or do not provide the necessary offloading capabilities for the iSCSI workloads.
