What RAID and drive configuration should be recommended?
A customer is creating a new configuration that has 100% sequential reads with very high
thread counts. The configuration will be for a test bed which will require no high availability or
fault tolerance on failures. What RAID and drive configuration should be recommended?
What is the difference in disk IOPS between RAID 1/0 and RAID 5 for this workload?
Click the calculator icon in the upper left-hand corner. An application generates 1000 IOPS
with a read/write ratio of 3:1. What is the difference in disk IOPS between RAID 1/0 and
RAID 5 for this workload?
Which naviseccli performance counter is used to view stripe boundary crossing statistics?
Which naviseccli performance counter is used to view stripe boundary crossing statistics?
what would be the outcome of adding these drives?
Refer to the Exhibit.
A VNX Administrator is monitoring the workload and is considering adding a few flash drives.
Based on the workload shown in the illustration, what would be the outcome of adding these
drives?
what does workload skew measure?
In reviewing a nar analysis, what does workload skew measure?
what could cause this utilization?
If the workload graph shows that most of the Storage Processor load is used to support a
small amount of data, what could cause this utilization?
Which utility would the customer use to provide performance reports on host block device activity?
Your customer is having performance problems on their Linux database servers that are
attached to a VNX. You have diagnosed the VNX and found no obvious issues. Which utility
would the customer use to provide performance reports on host block device activity?
Which “server_stats” statistic type would you use to get the desired information?
You are conducting an analysis of a Celerra system to migrate the data to a new VNX
Unified storage system. You want to collect statistical information about CIFS file system
activity. Which “server_stats” statistic type would you use to get the desired information?
Which correlated statistic can accomplish this job?
A customer has a mix of Windows and Linux clients accessing file systems on a VNX for File
system. The Storage Administrator wants to track and examine different types of correlated
file system read and write operations statistics for all clients.
Which correlated statistic can accomplish this job?
Which utility should you recommend?
A customer is implementing a VNX for File solution in a performance-oriented application
environment. There are Windows and Linux VM clients accessing the file systems. The
customer wants to track both file system and Data Mover utilization. The administrator
prefers GUI to CLI access. Which utility should you recommend?
