Create a Consistency Group for the application: The first step is to create a Consistency Group (CG) in the RecoverPoint system for the mission-critical application. This CG will manage the replication and ensure consistency across the volumes.

Determine the number of replication sets: Each volume provisioned from the VNX for the application will be represented as a separate replication set within the CG. Since there are three volumes, there will be three replication sets.

Configure replication sets: Each replication set will include the production volume (source) and the replica volume (target). The replication sets will be managed under the same CG to maintain consistency across all the application data.

For more detailed information, you can refer to the Dell EMC RecoverPoint documentation, which provides guidelines on how to configure replication sets within a CG. It is also advisable to consult the RecoverPoint Deployment Manager for step-by-step instructions on setting up and managing CGs and replication sets1.

Deployment Manager Overview: The Deployment Manager is a tool used to install and configure RecoverPoint clusters. It guides users through various steps to ensure the proper setup and configuration of the system.

Prepare New Cluster for Connection: During this step, the Deployment Manager prepares the new cluster for connection to the existing infrastructure. This involves several sub-steps, including network configuration, validation of the environment, and ensuring that all necessary components are in place.

Adding Licenses: As part of the ''Prepare New Cluster for Connection'' step, new RecoverPoint licenses are added to the cluster. This is crucial because the licenses enable the functionality of the RecoverPoint system, allowing it to perform replication and recovery tasks.

Verification: After adding the licenses, the Deployment Manager verifies that the licenses are correctly applied and that the cluster is ready for the next steps in the deployment process.

For a two-node vRPA cluster, a minimum of 9 IP addresses is required. This includes IP addresses for management, replication, and other network communication needs necessary to maintain high availability and proper functioning of the vRPA cluster.

To calculate the minimum required size for the Journal volume, we can use the provided formula and input the given parameters:

Average Write Traffic: 5 Mb/s

Required Rollback Time: 24 hours (which is 24 * 60 * 60 = 86,400 seconds)

Default Parameters: Assuming the image access log percentage is 20% (which is a common default), and the reserved for marking is negligible.

Using the formula:

\text{Journal size} = 1.05 \times (\text{write traffic}) \times (\text{rollback time in seconds}) / (1 - \text{image access log percentage})Journalsize=1.05(writetraffic)(rollbacktimeinseconds)/(1imageaccesslogpercentage)

We plug in the values:

\text{Journal size} = 1.05 \times (5 \text{ Mb/s}) \times (86,400 \text{ seconds}) / (1 - 0.2)Journalsize=1.05(5Mb/s)(86,400seconds)/(10.2)

Converting Mb to GB (1 Mb = 1/8,000 GB):

\text{Journal size} = 1.05 \times (5/8,000 \text{ GB/s}) \times 86,400 / 0.8Journalsize=1.05(5/8,000GB/s)86,400/0.8

\text{Journal size} = 1.05 \times 0.000625 \text{ GB/s} \times 86,400 / 0.8Journalsize=1.050.000625GB/s86,400/0.8

\text{Journal size} = 1.05 \times 54 \text{ GB} / 0.8Journalsize=1.0554GB/0.8

\text{Journal size} = 70.875 \text{ GB}Journalsize=70.875GB

Since we need to round up to ensure we have enough space, the minimum required size for the Journal volume is approximately 72.4 GB.

This calculation ensures that the Journal volume is adequately sized to handle the write traffic and maintain the required rollback time, providing a buffer for the image access log1.

In order to perform dynamic resizing of a replication set, the requirement is:

B . Both production and the copies must be provisioned from an XtremIO array

Explanation: Dynamic resizing of a replication set requires both the production and replica copies to be provisioned from an XtremIO array. XtremIO's architecture supports this dynamic resizing capability, allowing administrators to adjust the size of the replication set without interrupting ongoing operations.
