During a design session with the customer, you determine that they require all tier one LUNs on the production VNX be replicated to a remote VNX. They also require the ability to be able to restore or mount the data at any given time during the day.

What replication technology would you recommend?

A customer wants to use RecoverPoint/SE CRR. They have just realized that they need to use RecoverPoint write splitters, but do not understand how they work.

What does the splitter do after it intercepts a write I/O meant for a RecoverPoint Protected LUN?

You are sizing a new RecoverPoint/SE CRR installation for a customer. You have gathered data from their environment and have decided that they will need 142 consistency groups.

How many RecoverPoint clusters at each site must you plan for?

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?

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?

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?

How is RPO calculated in MirrorView/A environments?

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?

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.
