What is a performance concern when the last VNXsnapshot for a Thick LUN is deleted?

Your customer is experiencing performance degradation when deleting VNX Snapshots.
What technique would you recommend to avoid the defragmentation process that is
occurring?

A customer has configured replication between Data Movers on two VNX arrays. In order to
provide maximum network performance for the replication process, the customer has
configured link aggregation on each Data Mover to provide two Gigabit Ethernet ports per
Data Mover to the replication process. While reviewing performance reports the customer
notices the replication network is using less than 30% of the available bandwidth. What
change will increase the efficiency of the replication network bandwidth?

What is the main reason MirrorView/S has a lower effect on CPU utilization compared to
MirrorView/A?

Click the calculator icon in the upper left-hand corner.

An application generates 800 random 16 kB IOPS with a R/W ratio of 3:1. An MV/A mirror is
started on the application LUN. The update cycle is configured to be 15 minutes, and
updates take 6 minutes to complete. Assume that the data rate is constant. What is the
minimum space that should be configured for the Reserved LUN Pool on the secondary
VNX?

An application generates 500 random 8 kB IOPS with a R/W ratio of 3:1. An asynchronous
mirror is started on the application LUN. The update cycle is configured to be 30 minutes,
and updates take 15 minutes to complete. Assume that the data rate is constant. What is the
minimum space that should be configured for the Reserved LUN Pool on the secondary
VNX?

When using VNX Replicator for File why is it important to configure the SavVol on different
drives from the PFS whenever possible?

You have to architect a block migration to a VNX for a customer. Which attribute of
incremental SAN Copy for this migration would allow you to migrate the LUNs with minimal
down time?

When designing a SAN Copy migration what is the limitation of a SAN Copy Pull migration?

A customer has implemented MirrorView/A.
What determines the upper limits for MV/A performance?
