Dell EMC Specialist – Implementation Engineer, PS Series — Question 24

A customer wants to add an SC420 and an SC200 to a SC7020 storage array. What is the recommended approach to adding the new enclosures?

Answer options

• A. One single SAS chain connected to a 6 Gb SAS card
• B. One single SAS chain connected to a 12 Gb SAS card
• C. Two separate SAS chains connected to a 6 Gb SAS card
• D. Two separate SAS chains connected to a 12 Gb SAS card

Correct answer: D

Explanation

The correct answer is D because using two separate SAS chains connected to a 12 Gb SAS card allows for better performance and bandwidth for the additional enclosures. Options A and C do not utilize the higher bandwidth of the 12 Gb SAS card, while option B only suggests a single chain, which may limit scalability and performance.
