EMC RecoverPoint protects storage array logical unit numbers (LUNs) and provides concurrent local and remote data replication. RecoverPoint also provides continuous data protection for operational and disaster recovery by enabling any point-in-time recovery (PITR) for diversified storage environments both within and across pods.
RecoverPoint secures data by providing synchronous and asynchronous replication across heterogeneous arrays for block-based storage protocols. Replication improves reliability, fault-tolerance, and accessibility to data. If data becomes compromised or lost, you can look at data back in time and recover it by extending the vCenter VMware Site Recovery Manager (SRM) functionality with PITR capabilities.
RecoverPoint provides the ability to do the following:
Enable continuous data protection for any PITR to optimize the recovery point objective (RPO) and recovery time objective (RTO).
Ensure recovery consistency for inter-dependent applications.
Provide synchronous or asynchronous replication policies.
Reduce WAN bandwidth consumption and utilize available bandwidth optimally.
In Cisco UCS Director, you can access the following EMC RecoverPoint reports for Vblock clusters:
Consistency groups that ensure that there is application-dependent write consistency of application data on VPLEX distributed virtual volumes within the VPLEX system in the event of a disaster.
Consistency group copies of the initial consistency groups.
Replication sets that consist of a production source volume and its local or local and remote replica volumes. One or more replication sets makes up a consistency group.
Note | For more details about scalability and configuration options, see the EMC RecoverPoint documentation. |
Cisco UCS Director tests the connection to the EMC RecoverPoint server. If that test is successful, it adds the RecoverPoint account and discovers all infrastructure elements in the storage system that are associated with that account. This discovery process and inventory collection cycle takes few minutes to complete.
The polling interval configured on the System Tasks tab on the window specifies the frequency of inventory collection. For more information about configuring the polling interval, see the Cisco UCS Director Network Devices Management Guide.
RecoverPoint Appliance (RPA) clusters are a group of two to eight physical (or virtual) RPAs at the same geographic location. These clusters work together to replicate and protect data.
You can assign a RecoverPoint cluster to a pod in Cisco UCS Director. This configuration is optional.

In EMC RecoverPoint, volumes are protected by consistency groups. A consistency group ensures that updates to production volumes are also written to copies in a consistent and correct write-order. This configuration ensures that the copy can always be used to continue working from, or to restore the production source. The volumes must be replicated together in one consistency group to guarantee that at any point in time, the saved data is in true form. If two data sets are dependent on each other (such as a database and a database log), they should be part of the same consistency group.
EMC RecoverPoint also supports simultaneous bidirectional replication. With this type of replication, the same RecoverPoint appliance (RPA) can serve as the source RPA for one consistency group and the target RPA for another consistency group.
For more detailed guidelines about RecoverPoint consistency groups, see the EMC RecoverPoint Administrator's Guide, which can be obtained from EMC.
This procedure provides an overview of how to set up replication with a RecoverPoint consistency group in Cisco UCS Director.
Step 1 | Create a consistency group with a production copy. |
Step 2 | Create a consistency group copy to act as the replica for the production copy. |
Step 3 | Create a replication set for each production volume that you want to replicate. |
Step 4 | Add one or more user volumes to the consistency group copy in a replication set.
The user volume is the primary volume in a replication set that contains the data you want to protect. See Adding a User Volume to a Consistency Group Copy. |
Step 5 | Add one or more journal volumes to the consistency group copy in a replication set
Journal volumes hold system information or point in time history and can be either a copy journal or a production journal. See Adding a Journal Volume to a Consistency Group Copy. |
Step 6 | Add a link to a consistency group copy.
This link is used to transfer data between the production copy and the replication copies. See Adding a Link Between Consistency Group Copies. |
Step 7 | Enable the consistency group. |
Step 8 | Enable the consistency group copy. |
Step 9 | Start the data transfer.
You must initiate the first data transfer. It does not start automatically. See Starting Data Transfer for a Consistency Group and Starting a Transfer for a Consistency Group Copy. |

You can collect the latest snapshot image for a consistency group.
A snapshot is a point in time marked by the system for recovery purposes. A snapshot includes only the data that has changed from the previous snapshot. Once the system distributes the snapshot to the remote storage system, the snapshot creates a new current image on the remote storage system. A snapshot is the difference between one consistent image of stored data and the next consistent image of stored data.

The consistency group copy in a replication set contains at least one user volume and one journal volume. These volumes hold the data for replication.
The user volume is the primary volume in a replication set. This volume contains the data you want to protect.
Each consistency group copy must include one or more journal volumes that are dedicated to holding system information or point in time history. The type of information contained in a journal volume depends upon the journal type.
You can add one of the following types of journals:
Copy journal—Copy journals are dedicated to holding point-in-time information for each image on the production storage. They also hold bookmarks for significant points in time. The copy journals hold all changes to data, so that the copy storage can be rolled back to a previous point in time (PIT).
Production journal—Production journals are dedicated to storing information about the replication process. This marking information makes synchronization between the production and copy volumes more efficient. A production journal does not contain snapshots. Since this volume is used for failover, we recommend that you configure journal protection policies for the production journal.
The user volume is the primary volume in a replication set. This volume contains the data you want to protect.

EMC RecoverPoint transfers data across a communication connection between the production copy and the replication copies in the replication set of a consistency group. When the link is open, data can be transferred between consistency group copies.
You can start the transfer of data from a production copy to all other replication copies in a consistency group within a RecoverPoint appliance (RPA) cluster.
When you configure the link for the data transfer, you choose the replication mode that you want to use for the transfer. This mode can be one of the following:
Asynchronous—Replication in asynchronous mode creates a data copy that is synchronized automatically at specified intervals. The Recoverry Point Objective (RPO) that you configure for the link determines the length of these intervals. The default RPO is 25 seconds. In this mode, the host application initiates the data transfer, but does not wait for an acknowledgment from the remote vRPA before it initiates the next write. This is the default replication mode.
Synchronous—Replication in synchronous mode creates a data copy that is always in sync with the production source. In this mode, the host application initiates the data transfer, then it waits for acknowledgment from the remote vRPA before starting the next transfer.

In RecoverPoint, group sets let you automatically bookmark a set of consistency groups at pre-defined intervals to manage consistency. The bookmark represents the same recovery point in each consistency group in the group set. It allows you to define consistent recovery points for consistency groups that are distributed across different RecoverPoint appliances. Group sets provide automatic management of consistent points in time across consistency groups that are dependent on each other, or that must work together.
For more detailed guidelines about group sets, see the EMC RecoverPoint Administrator's Guide, which can be obtained from EMC.
