The maximum number of concurrent initial syncs that can be performed in a Unity VSA setup with RecoverPoint is:

B . 16

Explanation: In a Unity VSA setup with RecoverPoint, the system supports a maximum of 16 concurrent initial synchronizations. This limit ensures optimal performance and resource management during the synchronization process.

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.

The factors to be considered when using Deployment Manager to connect a RecoverPoint cluster to an existing cluster are:

C . License Type and Connectivity Protocol

Explanation: When connecting a RecoverPoint cluster to an existing one, it is crucial to consider the license type to ensure compatibility and the connectivity protocol (such as FC or iSCSI) to ensure proper network setup and communication between the clusters.

Reference: Dell RecoverPoint for Virtual Machines 6.0.1 vSphere HTML5 Plugin Administrator's Guide, Chapter on Cluster Connectivity and Configuration.

Access the Cluster Management Interface: Use a web browser to navigate to the RecoverPoint Cluster Management IP address.

Navigate to the Load Statistics: Append /info/long_term_statistics to the Cluster Management IP in the browser's address bar.

View the Report: The RecoverPoint Cluster Load report can be viewed on this page, which provides long-term statistics including load information.

This method allows administrators to retrieve historical load data even if they did not capture the output at the time the capture load command was run1.

Repository Volume: This is a special volume used by RecoverPoint for storing metadata about the system's configuration and the data it protects. It is essential for the operation of RecoverPoint and must be present on any array that is part of a RecoverPoint/EX cluster1.

Journal Volume: The journal volume is used to store changes to protected data. It allows RecoverPoint to recover data to any point in time within the journal window. Like the repository volume, it is a required component of a RecoverPoint/EX cluster1.

When adding volumes from an unlicensed array to a RecoverPoint/EX cluster, both repository and journal volumes are supported and required for the cluster's operation. The administrator must ensure that these volumes are properly configured to meet the system's requirements1.
