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?

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?

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?

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?

Click on the calculator icon in the upper left-hand corner. A customer has a 2 TiB LUN which will
be mirrored with MirrorView/S. Analyzer shows the current workload to be 500 8 KiB IOPs with a
R/W ratio of 3:1. The customer requires that the mirror should resynchronize within 2 hours if
fractured for 10 minutes or less. How much bandwidth is required to meet customer requirements?

Click on the calculator icon in the upper left-hand corner. A customer has a 1 TiB LUN which will
be mirrored with MirrorView/S. Analyzer shows the current workload to be 600 8 KiB IOPs with a
R/W ratio of 2:1. The customer requires that the mirror should resynchronize within 90 minutes if
fractured for 15 minutes or less. How much bandwidth is required to meet customer requirements?

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.
How can this be done?

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?

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?

If the total primary image workload consists of 1 KiB random I/Os with a R/W ratio of 3:1, what is
the maximum bandwidth required for the link between the VNX systems?
