Considering LUN compression in a VNX, how has initial compression performance changed
in VNX with MCx?

A customer designed an environment using VNX LUNs presented to individual hosts. They
configured a Pool to start using both Thick and Thin LUNs. One of the standalone servers is
an archive server running on Windows. They want to maximize capacity on the standalone
server since the data is no longer accessed. They have no more drives to increase LUN
capacity.
How can the customer increase available capacity to the archive server?

A customer is considering purchasing a new VNX with MCx. They have a performance
sensitive application and would like to use the Thin LUN to maximize pool capacity. What
would you recommend the customer consider before proceeding with this design?

A customer is considering purchasing a new VNX with MCx. Performance of the application
is the top priority. What would you recommend the customer consider before proceeding
with this design?

What is a restriction for the High Bandwidth option for classic LUNs?

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
Ten 600 GB 15 krpm SAS drives configured as 4+1 RAID 5
Sixteen 2 TB NL-SAS drives configured as 6+2 RAID 6
The customer’s workload consists of 4 kB random I/Os with a R/W ratio of 2:1.
How many host IOPs can the pool support?

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?
