EMC D-MSS-DS-23 Exam With Confidence Using Practice Dumps

Whenonly two SAS ports are available on each Storage Processor (SP) in a Dell Unity XT Disk Processor Enclosure (DPE), therecommended order for connecting DAEsis toalternate DAEs between buses (SAS Bus 0 and SAS Bus 1)to achieve balanced performance and availability.

✅Recommended Order (per Dell EMC Best Practices Guide):

DAE 1→ Connect toSAS Bus 1

DAE 2→ Connect toSAS Bus 0

DAE 3→ Connect toSAS Bus 1

✅Why this order?

Alternating DAEs between buses ensures even distribution of I/O load across the two buses.

It enhances fault tolerance and reduces the risk of performance bottlenecks or single points of failure.

This arrangement follows Dell’s best practice to alwaysbalance the number of DAEs across SAS buseswhenever possible.

❌Why not the other options?

A and D– These do not alternate buses, leading to unbalanced bus usage and potential bottlenecks.

B– Does not balance DAEs evenly across the two buses.

C– Alternates the buses for each DAE, following the recommended best practice for2-port DPE configurations.

The commandsupportshowis used to gather comprehensive data from Brocade switches. This command collects extensive diagnostic information about the switch, including configuration details, hardware status, and various operational statistics. Here's a step-by-step explanation of thesupportshowcommand:

Access the Brocade Switch:Connect to the Brocade switch via SSH or through a console connection.

Enter the Command:Typesupportshowin the command line interface (CLI) and press Enter.

Data Collection:The command will begin collecting a wide array of information from the switch. This includes:

Hardware and firmware versions

Port status and configurations

Zoning information

Error logs and statistics

Environmental data (temperature, power supply status, etc.)

Output Review:The gathered data is typically extensive and can be used for troubleshooting, performance analysis, and ensuring the switch is operating correctly.

Save the Output:The output can be redirected to a file for later review or analysis by technical support teams.

The Dell Unity XT 380F array is equipped with converged network adapter (CNA) ports, while the Dell Unity XT 880F array features embedded mezzanine ports. These differences in port configurations reflect the varied performance and connectivity options available in different models of the Unity XT series.
