what is the initial compression bandwidth?
In VNX with MCx, if the Block compression rate is set to high, what is the initial compression
bandwidth?
Which workload characteristic of the application would produce poor access times on a compressed LUN?
A customer created a Thin LUN, enabled compression on a Pool, and installed their email
application environment. The application is showing poor performance. Which workload
characteristic of the application would produce poor access times on a compressed LUN?
What happens to the LUN when it becomes compressed?
A customer needs to reclaim space and has decided to enable compression on a Thick LUN
in their environment.
What happens to the LUN when it becomes compressed?
what percent full will host I/O be terminated to the LUN?
During decompression with default settings, if the pool becomes too full, decompression will
be paused but host I/O can continue. At what percent full will host I/O be terminated to the
LUN?
how has initial compression performance changed in VNX with MCx?
Considering LUN compression in a VNX, how has initial compression performance changed
in VNX with MCx?
How can the customer increase available capacity to the archive server?
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?
What would you recommend the customer consider before proceeding with this design?
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?
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?
What is a restriction for the High Bandwidth option for classic LUNs?
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
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.
