Which replication solution supports the use of physical media to transport the initial copy?
You have been asked to design a replication solution for file data. The replication will be from a customer’s remote data center to their primary data center. The distance between the data centers is 1200 km. The initial synchronization is 125 Gb of data over a WAN (1.2 Mb/s) with a 33 ms delay.
Which replication solution supports the use of physical media to transport the initial copy?
How many locations or targets can Replicator support?
During a design session with the customer you discover a need to replicate the source VNX to many locations for Disaster Recovery requirements.
How many locations or targets can Replicator support?
What would you recommend to avoid interruption?
Your customer calls you about their new replication solution. CIFS access is being interrupted intermittently on the replication target.
What would you recommend to avoid interruption?
What is a recommended configuration to have CIFS replicated?
A new customer is looking at purchasing two new VNXs and wants to replicate the CIFS environment.
What is a recommended configuration to have CIFS replicated?
Under what conditions would you increase the TOS setting?
During data collection, the Time Out of Sync (TOS) setting is currently set at 10 minutes. You recommend a larger TOS setting based on the data that will be replicated.
Under what conditions would you increase the TOS setting?

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
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 60,000 LUN IOPs in this role. The primary system is also a VNX.
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?
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?
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?
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.
