What is the most likely cause?
Your customer has recently seen a significant increase in overall useable capacity of their CIFS file shares after enabling file-based deduplication. They have also noticed a significant decrease in the overall available storage on the VNX system.
What is the most likely cause?
What approach solves the requirement with least disk overhead?
A customer requests to have 90 SnapSure checkpoints for every file system. After an interview with the administrator, you learn that the company has to comply with an industry requirement of keeping data on disk for a quarter.
What approach solves the requirement with least disk overhead?
How many COFWs will be performed each time the clone is resynchronized?
Click on the calculator icon in the upper left-hand corner.
Customer requirements call for a SnapView snapshot to be made of a clone prior to resynchronization. The source LUN is 512 GiB, and performs 550 random reads/s and 10 random writes/s of 4 KiB. The clone will be fractured every 10 minutes, and resynchronized after the snapshot is started.

Which applications will cause performance issues?
A customer would like to implement SnapView but has expressed concern about performance.
Which applications will cause performance issues?
How can the backup activity impact the host performance on the source LUN?
A snapshot is being used to perform a backup of the LUN. How can the backup activity impact the host performance on the source LUN?
What is the expected initial bandwidth at which data chunks will be written into the Reserved LUN Pool?
Click on the calculator icon in the upper left-hand corner. A customer wants to add a SnapView snapshot to a 600 GiB LUN. Captured data show that the LUN has an access rate of 1000 IOPs with a read/write ratio of 4:1, and 8 KiB IOs. What is the expected initial bandwidth at which data chunks will be written into the Reserved LUN Pool?
What is the expected initial bandwidth at which data chunks will be written into the Reserved LUN Pool?
Click on the calculator icon in the upper left-hand corner. A customer wants to add a SnapView snapshot to a 500 GiB LUN. Captured data show that the LUN performs 500 4 KiB IOPs with a read/write ratio of 3:1. What is the expected initial bandwidth at which data chunks will be written into the Reserved LUN Pool?
Which response provides the best answer?
A customer has purchased a VNX array and is in the process of allocating RAID 5 (4+1) storage. They have asked you for best practices on number and placement of LUNs for the Reserved LUN pool.
Which response provides the best answer?
Which checkpoint interval in minutes should you recommend?
Click on the calculator icon in the upper left-hand corner. Your customer has the following requirements for their CIFS home directories:
– Checkpoint every 10 minutes
– Data retention 24-hours
– Self-service file-level recovery
