A customer creates a multi-tiered pool with the following configuration:
Five 200 GB FAST VP optimized Flash drives configured as 4+1 RAID 5
Five 600 GB 15 krpm SAS drives configured as 4+1 RAID 5
Twenty-four 2 TB NL-SAS drives configured as 6+2 RAID 6
The customer’s workload consists of 8 kB random I/Os with a R/W ratio of 2:1.
How many host IOPs can the pool support?

A customer has an application that uses a dataset of 15 TB. The skew for the application is
97%. The application requires storage capable of performing 10,000 IOPs. The application
R/W ratio is 3:1
The VNX system for the application has the following disk configuration:
Ten FAST Cache optimized 200 GB Flash drives
Ten FAST VP optimized 100 GB Flash drives
Twenty 600 GB 15 krpm SAS drives
Fifty 2 TB NL-SAS drives
The customer wants to implement the most efficient solution. How should the pool for the
application be configured?

A customer has an application that uses a dataset of 20 TB. The skew for the application is
97%. The application requires storage capable of performing 13,000 IOPs. The application
R/W ratio is 3:1

The VNX system for the application has the following disk configuration:
Ten FAST Cache optimized 200 GB Flash drives
Ten FAST VP optimized 100 GB Flash drives
Twenty 600 GB 15 krpm SAS drives
Fifty 2 TB NL-SAS drives
The customer wants to implement the most efficient solution. How should the pool for the
application be configured?

A Customer is considering purchasing a new VNX but can’t decide whether to go with
Classic RAID groups or pools. They would like to know the performance differences between
the two when creating Thick LUNS.
What would be the best response?

Which is an EMC Best Practice when configuring the High Bandwidth option for Pool LUNs?

A customer asks about the High Bandwidth option for a data warehousing application. The
customer would like to know the benefits of implementing this feature. How do you respond?

A customer recently added a large number of new users to their VNX for Block storage
system. They now notice that the system is slow. You have been asked to fix this problem.
Their configuration uses only Classic LUNs. They have some unused Flash drives. Analysis
shows that several LUNs have skew rates of 90% or higher. Which technology would you
implement to solve their performance problem?

A VNX customer is using storage pools and FAST Cache to support a mixed workload
environment. The mission-critical application is SAP with an underlying MS SQL database.
The SQL database has an IO profile that is well suited for FAST Cache. The customer would
like to increase the efficiency of FAST Cache while not degrading the performance in any
way. Cost is not a consideration. What action should the SE recommend to improve FAST
Cache efficiency?

Click the calculator icon in the upper left-hand corner. Your customer wants to use a
SnapView Snapshot of a Pool LUN as part of their backup strategy. You need to determine
whether or not the proposed RLP configuration will meet the performance requirement. The
source LUN performs 800 random 4 kB IOPS, with a 3:1 R/W ratio. At what rate is chunk
data written into the RLP when the session starts?

A Snapshot Source LUN performs 650 random 16 kB IOPs, with a 4:1 R/W ratio.
At what rate is chunk data written into the RLP when the session starts?
