How can this be done?
Your customer wants to set up MirrorView/S between VNX arrays in their primary and secondary data centers. The two data centers are located 50 kilometers apart. Both VNX arrays are running Unisphere version 1.1.

What is the best practice for FAST Cache on MirrorView/A?
You are reviewing the array configuration of a VNX array that has MirrorView/A enabled. You notice that all the images related to MirrorView/A have FAST Cache disabled. What is the best practice for FAST Cache on MirrorView/A?
If the primary image workload consists of 4 KiB random IOs with a R/W ratio of 3:1, what is the maximum bandwi
Click on the calculator icon in the upper left-hand corner. Your customer wants to use a VNX system at an unmanned DR site. The system will be used exclusively as a secondary MirrorView/A system, and it is capable of performing 30,000 LUN IOPs in this role. The primary system is also a VNX.
If the primary image workload consists of 4 KiB random IOs with a R/W ratio of 3:1, what is the maximum bandwidth required for the link between the VNX systems?
How much data is moved across the link in the 30-minute period?
Your customer plans to use Incremental SAN Copy as part of a DR solution. The Source LUN is 512 GiB in size, and a clone of this LUN will be used as the ISC source LUN. The host accessing the LUN generates 500 4 KiB IOPS with a R/W ratio of 3:1. The clone is fractured every 30 minutes, and an ISC update is performed.
How much data is moved across the link in the 30-minute period?
How much data is moved across the link in the 20- minute period?
Your customer plans to use Incremental SAN Copy as part of a DR solution. The Source LUN is 256 GiB in size, and a clone of this LUN will be used as the ISC source LUN. The host accessing the LUN generates 500 4 KiB IOPS with a R/W ratio of 9:1. The clone is fractured every 20 minutes, and an ISC update is performed. How much data is moved across the link in the 20- minute period?
What is the best practice for FAST Cache for component LUNs of a metaLUN source?
You are reviewing the MirrorView/S configuration on a VNX array. The source LUN is a metaLUN. What is the best practice for FAST Cache for component LUNs of a metaLUN source?
How much data will be copied to the secondary as part of the resynchronization process?
A customer has a 512 GiB primary MirrorView/S image. The image workload is 1,000 IOPs of random 4 KiB IOs, with a R/W ratio of 3:1. The secondary image is fractured for 30 seconds as the result of a connectivity failure. How much data will be copied to the secondary as part of the resynchronization process?
How much data will be copied to the secondary as part of the resynchronization process?
A customer has a 256 GiB primary MirrorView/S image. The image workload is 1,000 IOPs of random 8 KiB I/Os, with a R/W ratio of 3:1. The secondary image is fractured for 20 seconds as the result of a connectivity failure. How much data will be copied to the secondary as part of the resynchronization process?
What IP address should they use to accomplish this?
You have been working with a customer on sizing and implementing a RecoverPoint/SE CDP solution into their environment. The customer calls you, wanting to know how they can log in to the RecoverPoint application.
What IP address should they use to accomplish this?
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.
