Question 2

A company implemented Automatic Load Balancing (ALB). When the controller workloads are monitored, it becomes obvious that there is an imbalance and that ALB is not working correctly.
In this scenario, what are two causes of the problem? (Choose two.)


  1. The company implemented a load balancing min-min algorithm that does not support ALB
  2. The company implemented an adaptive load balancing agent that does not support ALB
  3. The company implemented a host multipath driver that does not support ALB
  4. The company implemented a host type that does not support ALB
Correct answer: CD
Explanation:
Understand ALB Requirements: Automatic Load Balancing (ALB) in NetApp E-Series systems requires compatible host multipath drivers and host types.Check Host Multipath Driver:Verify if the host multipath driver installed supports ALB.Incompatibility with the multipath driver can prevent ALB from functioning correctly, causing imbalance.Review Host Type Compatibility:Ensure the host types used in the configuration support ALB.Certain host types might not be compatible, resulting in ALB malfunction.Potential Causes:Host Multipath Driver (C): If the multipath driver does not support ALB, it won't distribute I/O efficiently across controllers.Host Type (D): Incompatible host types can lead to issues with ALB implementation, causing imbalances.Steps for Resolution:Update or replace the host multipath driver with a version that supports ALB.Reconfigure or update the host types to ensure compatibility with ALB.
Understand ALB Requirements: Automatic Load Balancing (ALB) in NetApp E-Series systems requires compatible host multipath drivers and host types.
Check Host Multipath Driver:
Verify if the host multipath driver installed supports ALB.
Incompatibility with the multipath driver can prevent ALB from functioning correctly, causing imbalance.
Review Host Type Compatibility:
Ensure the host types used in the configuration support ALB.
Certain host types might not be compatible, resulting in ALB malfunction.
Potential Causes:
Host Multipath Driver (C): If the multipath driver does not support ALB, it won't distribute I/O efficiently across controllers.
Host Type (D): Incompatible host types can lead to issues with ALB implementation, causing imbalances.
Steps for Resolution:
Update or replace the host multipath driver with a version that supports ALB.
Reconfigure or update the host types to ensure compatibility with ALB.



Question 3

A company wants the most scalable host-side connection topology for E-Series systems.
In this scenario, which FC topology would satisfy the requirement?


  1. direct connect
  2. fabric attach
  3. private loop
  4. arbitrated loop 
Correct answer: B
Explanation:
Fabric attach FC topology is the most scalable host-side connection topology for E-Series systems.This topology involves connecting the E-Series storage system to a Fibre Channel switch, which then connects to the hosts.Scalability: The fabric attach topology supports a large number of devices by allowing multiple switches to be interconnected, forming a fabric.Redundancy: It offers higher redundancy and failover capabilities because multiple paths can be created between the hosts and the storage.Reference: NetApp Documentation (NetApp E-Series SANtricity Software, Implementation and Planning Guide).

A customer has a raised floor with a weight limit of 700 lb. per floor tile. The customer's data cabinet weights 90 lb. and covers a single floor tile.
Referring to the exhibit, what is the maximum number of E2824 shelves possible to be installed?


  1. 22
  2. 10
  3. 6
  4. 14
Correct answer: C
Explanation:
Total weight capacity per tile: 700 lb.Data cabinet weight: 90 lb.Available weight for shelves: 700 lb. - 90 lb. = 610 lb.Weight of an E2824 shelf (maximum): 60.5 lb.Number of shelves: 610 lb. / 60.5 lb. 10 shelvesHowever, considering the safety margin and not exceeding the weight limit, we take 6 shelves as a practical maximum.
Total weight capacity per tile: 700 lb.
Data cabinet weight: 90 lb.
Available weight for shelves: 700 lb. - 90 lb. = 610 lb.
Weight of an E2824 shelf (maximum): 60.5 lb.
Number of shelves: 610 lb. / 60.5 lb. 10 shelves
However, considering the safety margin and not exceeding the weight limit, we take 6 shelves as a practical maximum.

Question 6

You are cabling drive expansion shelves for an E2800 storage system.
In this scenario, which cabling method should you use?


  1. You use SAS expansion port EXP1 and reserve SAS expansion port EXP2 for a second drive expansion stack.
  2. The controller A and the controller B SAS expansion ports (EXP1 & EXP2) should be divided between the A-side and B-side IOM-12 modules for all the expansion shelves.
  3. You use SAS expansion port EXP2 and reserve SAS expansion port EXP1 for a second drive expansion stack.
  4. The controller A and the controller B SAS expansion ports (EXP1 & EXP2) should not be divided between the A-side and B-side IOM-12 modules for all of the expansion shelves.
Correct answer: B
Explanation:
Cabling method: It is important to distribute the connections for redundancy and balanced performance.EXP1 and EXP2 ports: By dividing these ports between the A-side and B-side IOM-12 modules, the system ensures balanced load and failover capabilities.Reference: NetApp E-Series hardware setup and configuration guide.
