NOTE: Only templates configured with at least TPVV or CPVV type, size, and user CPG from Storage Systems associated with the selected ESX(i) host are displayed.

5.Select an appropriate template from the list based on the summary of details, then click Next.

You are then asked to provide the virtual volume parameters for the virtual volume being provisioned.

Figure 44 Virtual Volume Provisioning Parameters

6.Fill in the following parameters and click Next when done.

Number of virtual volumes: - Number of virtual volumes to create (1 – 99). The default is 1.

Virtual volume name prefix - Name for the virtual volume (1 – 31 characters for single volume creations or 1– 26 characters for multiple volume creations). If the number of virtual volumes to be created is set to 1, the specified name is sufficient for creating the virtual volume. When creating multiple virtual volumes, a decimal number is automatically appended to the name prefix for each virtual volume that is created up to the maximum limit (.0 - .9999).

NOTE: When choosing a name for creating virtual volumes, you must consider the following:

If the number of virtual volume count = 1, the virtual volume name is set to 31 and the Datastore name is set to 42.

If number of the virtual volume count > 1, the virtual volume name prefix is set to 26 and the Datastore name prefix is set to 31.

Size (512 MB – 16 TB) - Size for the virtual volume. For VMFS-3, the VV size range is 512 MB to 2 TB, For VMFS-5, the VV size range is from 512 MB to 16 TB.

When specifying the size for a virtual volume, 256 MB is reserved for each node. Depending on the cluster type, the minimum virtual volume size is calculated as 256 MB times the number of nodes.

In a two node system, 512 MB is reserved when a TPVV is created. If an 80% user limit is set for a 512 MB TPVV, only 410 MB of space can be allocated. However 512 MB is the least amount required so the creation of the virtual volume fails. In other words, If the allocation limit is set, the space after the % needs to be at least 512 MB in a 2 node cluster.

Recovery Manager Software for VMware vSphere specifications

HP Recovery Manager Software for VMware vSphere is a powerful tool designed to enhance the data recovery process for virtualized environments. It provides enterprises with a reliable solution to protect critical workloads and ensure business continuity, particularly in environments that leverage VMware's virtualization technology.

One of the main features of HP Recovery Manager is its seamless integration with VMware vSphere. The software utilizes VMware’s vSphere Storage APIs, enabling users to perform efficient backups and streamline disaster recovery processes. This integration allows for quiesced snapshots, which ensure data consistency during the backup process by momentarily pausing applications, thereby capturing a reliable state of the data.

Another significant characteristic of HP Recovery Manager is its ability to perform rapid, point-in-time recovery. This functionality is crucial for minimizing downtime after data loss incidents. Organizations can restore entire virtual machines, specific files, or applications quickly, allowing businesses to resume operations without lengthy interruptions.

Management is simplified through a user-friendly interface, which helps administrators monitor and manage backup tasks from a central dashboard. This centralized approach reduces the complexity often associated with managing multiple backup solutions in a virtual environment. Additionally, HP Recovery Manager supports automation features, where users can schedule regular backups, thus ensuring that the most current data is always protected without requiring constant manual intervention.

The software employs advanced technologies such as deduplication, which reduces the amount of storage space required for backups by eliminating duplicate data. This feature not only optimizes disk usage but also enhances overall backup performance by allowing faster backup times.

Furthermore, HP Recovery Manager provides robust reporting and analytics capabilities. Users can generate detailed reports on backup and recovery operations, allowing for better compliance and auditing. These insights aid in capacity planning and performance tuning, ensuring that the backup infrastructure remains efficient and effective.

In summary, HP Recovery Manager Software for VMware vSphere offers a comprehensive suite of features that provide a highly effective solution for data recovery in virtualized environments. Its integration with vSphere, rapid recovery capabilities, user-friendly management, storage optimization through deduplication, and robust reporting functionalities make it a valuable asset for organizations looking to protect their critical data and ensure business continuity.
