A clone source LUN is 2 TB in size. It performs 450 random 16 kB IOPs with a 2:1 R/W ratio.
As part of ongoing testing, the clone is fractured for five minutes and then resynchronized.
The testing is performed every hour.
How much data (to the nearest GB) is read from the source LUN as part of the
resynchronization process?

A clone source LUN is 512 GB in size. It performs 1500 random 4 kB IOPs with a 3:1 R/W
ratio. As part of ongoing testing, the clone is fractured for 10 minutes and then
resynchronized. The testing is performed every hour. How much data (to the nearest GB) is
read from the source LUN as part of the resynchronization process?

What is the best practice for where SavVol should be located?

Where does SnapSure place the SavVOL, by default?

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?

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?
