How should NAS RAID Groups be selected on the array for optimum AVM performance?
You are asked to design the backend layout for a large Unified Storage VNX. You find that the customer intends to use most of the disk space for block-level devices in the SAN.
How should NAS RAID Groups be selected on the array for optimum AVM performance?
Which statement offers the best storage pool guidance for file system creation with AVM?
You are planning a file-only implementation where the customer will be using AVM. You want to make the best use of storage pools to preserve the performance of VNX.
Which statement offers the best storage pool guidance for file system creation with AVM?
Which option will increase the customer’s overall bandwidth while maintaining EMC best practices for iSC
Your customer is using the front-end iSCSI ports on their VNX. They are experiencing long delays and reduced bandwidth as they add servers to their environment.
Which option will increase the customer’s overall bandwidth while maintaining EMC best practices for iSCSI?
What do you advise them?
A customer is concerned about UserMapper database and asks you what will happen to the VNX CIFS users if UserMapper is unavailable.
What do you advise them?
What EMC solution do you propose?
Your customer has recently purchased a VNX for File. Due to the budget limits, they were unable to purchase enough SAS drives to create all of their required file shares. They would like to use their NL-SAS drives but are concerned about lower performance.
What EMC solution do you propose?
What is the best recommendation when designing the CIFS storage pool?
Your customer is designing a CIFS application with very specific high CIFS I/O requirements.
What is the best recommendation when designing the CIFS storage pool?
What would you change in this design?
Refer to the exhibit.
While trying to maximize availability for CIFS clients, the customer has designed the following 10 Gb/s IP environment. What would you change in this design?
a. Ensure every connection has a failover to another switch.
b. Two Nexus switches are needed and the connection to the third switch removed.
c. Add three more connections to the VNX.
d. Change from LACP to EtherChannel for higher performance.
e. Upgrade to a VNX7500 to provide additional Data Movers.
Which statement best describes the choices available?
You get a call from the customer asking about Active Directory integration for user mapping. They have used EMC NAS products for over ten years and have extended the schema some years ago. Now they are trying to migrate to default Windows Services for UNIX (SFU, aka IDMU) for the UID/GID needs.
Which statement best describes the choices available?
In your scenario, which hot spare drive would the array first select to replace the failed drive?
After reviewing the design for their new VNX, your customer has requested further explanation of the hot spare algorithm used by the array. You propose the following scenario:
RAID group 200 consists of five 600 GB 10K SAS drives in a RAID 5 configuration. Within this RAID group there are three 25 GiB LUNs. One of the five drives has just failed.
In your scenario, which hot spare drive would the array first select to replace the failed drive?
What software option is required to support this implementation?
Your customer is designing a VNX file system using CIFS quotas with a supported third-party application.
