Reserve volume – A snapshot reserve volume is automatically created when you create a snapshot. The reserve volume stores information about the data that has changed since the volume snapshot was created. When you delete a snapshot, the management software also deletes its associated reserve volume. You can create up to 256 volumes on each virtual disk.
Page 71 Volume capacity Identify the capacity of the volume in megabytes, gigabytes, or terabytes. The storage pool for this volume By default, the management software supplies a default storage pool.

4. In the Copy Priority field, select the copy priority you want. The higher the priority you select, the more resources will be allocated to the volume copy operation at the expense of the storage array’s performance. 5. Click OK. A confirmation message indicates that the change was successful.
Page 86: Configuring Volume Snapshots
Configuring Volume Snapshots This section describes configuring and managing volume snapshots. It contains the following subsections: “About Volume Snapshots” on page 70 “Planning Volume Snapshots” on page 72 “Calculating Reserve Volume Capacity” on page 73 “Managing Volume Snapshots” on page 76 About Volume Snapshots A snapshot is a copy of the data on a volume at the moment at which you create the snapshot.
Page 87 Note: A snapshot of data is not suitable for failure recovery. Continue to use offline backup methods to create full-volume backup copies. Snapshots on the array are copy-on-write or dependent copies. In this type of snapshot, write operations to the primary volume causes the management software to copy the snapshot metadata and copy-on-write data to the reserve volume.
Page 88: Planning Volume Snapshots
Planning Volume Snapshots Create a volume snapshot involves a number of tasks and decisions about a variety of factors. Therefore, before running the Create a Snapshot Volume wizard. The wizard, you should plan the following aspects of your snapshots: The name of the snapshot reserve volume When you create a snapshot, you must provide a unique name for the snapshot that enables you to easily identify the primary volume.
Page 89: Calculating Reserve Volume Capacity
The following options are available: Automatic – The management software automatically searches for and selects a virtual disk that matches the necessary criteria. If there are none, and enough space is available, it creates a new virtual disk. Create Volume on an Existing Virtual Disk – You manually select the virtual disks on which you want to create the volume from the list of all available virtual disks.
Page 90 The capacity needed for the snapshot reserve volume varies, depending on the frequency and size of I/O writes to the base volume and how long you need to keep the snapshot volume. In general, choose a large capacity for the reserve volume if you intend to keep the snapshot volume for a long period of time or if you anticipate heavy I/O activity, which will cause a large percentage of data blocks to change on the base volume during the life of the snapshot volume.
Page 91 set of 32 blocks, even if only one set of blocks has changed. Consider this when determining the percentage of the base volume's capacity that can be copied to the snapshot reserve volume. Use the following formula to calculate the amount of management overhead required to store snapshot data on the snapshot reserve volume.
Page 92: Managing Volume Snapshots
In the Create Snapshot Volume Wizard: Specify Reserve Capacity dialog box, use the percentage (%) of base volume to specify the estimated capacity of the snapshot reserve volume. When you create a snapshot, you will specify this snapshot reserve volume capacity as a percentage of the base volume.

It contains the following subtopics: “About the Replication Process”...
Page 100 The software replicates data from a primary volume to a secondary volume. The association between the primary and secondary volumes constitutes a replication set. After the volumes in a replication set have been initially synchronized, the software ensures that the primary and secondary volumes contain the same data on an ongoing basis.
Page 101: About Replication Sets
You can also restore data from a secondary volume to a primary volume by reversing the roles of the primary and secondary volumes. Role reversal is a failover technique in which a primary volume failure causes the secondary volume to assume the role of the primary volume.
Page 102 Array A Array B Replication Replication repository Physical connection repository volume volume Data Primary Secondary Volume Volume Relationship Between Arrays and Their Corresponding Replication Sets FIGURE 4-1 After you create a replication set, you can modify its properties (see “About Replication Set Properties”...
Page 103: About The Consistency Group
If the primary volume becomes unavailable, the secondary volume assumes the role of primary volume. This role reversal allows applications to continue their operations by using the newly designated primary volume. When the former primary volume is again available, you must synchronize it with the more recent data on the other volume to restore the functions of the replication set.
Page 104: About Replication Links
Consistency Group Guidelines (Continued) TABLE 4-3 Regarding Note Replication sets Replication sets in the consistency group must all use asynchronous replication mode. The consistency group supports up to 32 replication sets. A best practice is to plan the consistency group in advance and include the replication set in the consistency group at the same time that you create the replication set.
Page 105: About Primary And Secondary Role Reversal
Specify a secondary volume. When you create the replication set, the local volume assumes the primary role by default, and you are prompted to choose the secondary volume. Once the replication set is created, you can change the role of a volume on the Replication Set Details page as needed without suspending replication.
Page 106 Caution: If I/O operations to the primary and secondary volumes occur during a role reversal, data is lost when you initiate a synchronization operation. The current secondary volume is brought into synchronization with the current primary volume, and any writes that have been written to the secondary volume are lost. Secondary to Primary You usually promote a secondary volume to a primary volume in a replication set when a catastrophic failure has occurred on the array that contains the primary...
Page 107: About Replication Modes
About Replication Modes The replication mode is a user-selectable property that defines the communication mode for a replication set. The software supports two modes of data replication: Synchronous mode – In synchronous mode replication, a write operation to the primary volume is not confirmed as complete until the secondary volume has been updated.
Page 108: Reference: Synchronous Versus Asynchronous Replication Modes
Reference: Synchronous Versus Asynchronous Replication Modes When you choose a replication mode, consider the characteristics of each, as described in TABLE 4-4 Synchronous and Asynchronous Mode Comparison TABLE 4-4 Synchronous Replication Asynchronous Replication A write operation to the primary volume is not The write operation is considered complete as soon as considered complete until the user data is written to the user data is written to the primary volume.
Page 109: About Data Replication Operations
About Data Replication Operations You can choose one of the following data replication operations from the Replication Set Details page: Suspend – This operation temporarily stops replication of a replication set (or all of the replication sets in the consistency group with primary volumes on the primary array).
Page 110: General Planning Considerations
General Planning Considerations Replicating data and modifying replication properties may require a significant change to your system’s configuration. You must plan accordingly before you perform data replication operations. Consider the following: Business needs – When you decide to replicate your business data, consider the maximum delay: How long out of date can you allow the data on the secondary volume to become? This determines the replication mode and how often you should back up the data.
Page 111: Planning To Create Replication Sets
Planning to Create Replication Sets Before you can replicate data to a secondary volume, use the Create Replication Set wizard to create a replication set. Before you use the wizard, you must do the following: The storage domain definitions for the primary and secondary arrays are independent of each other.
