Support for multiple array pair configuration

HP 3PAR SRA supports multiple array pair configurations. Different remote copy groups from the array pairs can be part of a single recovery plan or separate recovery plan.

Support for virtual volume sets and host sets

HP 3PAR SRA supports vvset (virtual volume set) and host set features of HP 3PAR StoreServ Storage system.

The following are the HP 3PAR SRA pre-requisites for HP 3PAR host set and HP 3PAR virtual volume set features:

•For HP 3PAR OS versions 3.1.3 or later:

When an RC group is created, virtual volume set is automatically generated for the remote copy group virtual volumes in both primary and secondary HP 3PAR StoreServ Storage systems. To use the vv set feature for presenting LUNs to a host, then HP recommends that you use automatically created vv sets to present the virtual volumes to the host.

•For HP 3PAR OS version 3.1.2 MU3:

To use the vv set feature for presenting the primary LUNs to host, you must manually create the vv set and map the remote copy group virtual volumes to the created vv set in the primary HP 3PAR StoreServ Storage system. Similarly, HP recommends that you create the vv set manually in the secondary HP 3PAR StoreServ Storage system and map the RC group virtual volumes to the created vv set. In the event of failover, HP 3PAR SRA will use the manually created vv set to present LUNs to the host and HP 3PAR SRA does not create the vv set by itself.

All virtual volumes exposed via the same HP 3PAR virtual volume set and protected by SRM must belong to the same remote copy group.

If virtual volumes are from a virtual volume set with multiple VMs created, make sure to include all virtual volumes in a single remote copy group and in the same protection group. Otherwise, there is a potential of losing connectivity to the VMs if virtual volumes are included in more than one remote copy group and all remote copy groups are not included in the same protection group.

NOTE:

•If a remote copy group has virtual volumes that are not participating in datastore creation and if these virtual volumes are exposed to a different host, then there are chances of data corruption.

•You must make sure that all virtual volumes in remote copy group are participating in datastore. The virtual volumes in a remote copy group that are not participating in datastore creation must not be presented to a host.

•If the virtual volumes participating in an SRM configuration are exposed using a virtual volume set, any virtual volume member in this set, not used by SRM in the same protected group loses connectivity to the LUN after a failover.

•In the event of a failover, if the participating virtual volumes and hosts are part of vv set and host set respetively, then the LUNs are exposed using vv set and host set features.

•If the participating virtual volumes and host are not part of vv set and host set features, then the LUNs are exposed individually to the ESX(i) hosts.

System Replication Adapter Software QL227 for VMware specifications

HP System Replication Adapter Software QL227 for VMware is a sophisticated tool designed to enhance data protection and availability for virtualized environments. This software enables seamless replication of virtual machines (VMs) across different locations, ensuring business continuity even in the face of disasters or system failures.

One of the main features of QL227 is its ability to integrate tightly with VMware environments. It supports VMware vSphere, which is a leading virtualization platform, allowing users to leverage their existing infrastructure while benefiting from HP’s data replication technology. The adapter simplifies the process of setting up and managing replication tasks, which can be critical for organizations with stringent uptime requirements.

Another notable characteristic of the HP System Replication Adapter is its support for block-level replication. This technology ensures that only the changed data blocks are transferred to the secondary site, optimizing bandwidth usage and minimizing the impact on system performance. This feature is especially valuable for businesses that operate in environments with limited network capacity.

QL227 also includes advanced monitoring and reporting capabilities. Administrators can easily track the status of replication tasks, with real-time notifications and insights that help ensure data integrity and availability. Additionally, the software offers various recovery options, allowing users to initiate failover or failback processes with minimal disruption to operations.

The adapter’s compatibility with HP’s Enterprise Virtual Array (EVA) storage systems enhances its functionality even further, providing a robust infrastructure for managing replicated data. It is designed to work in conjunction with HP’s other data protection solutions, creating a comprehensive strategy for safeguarding critical business information.

Moreover, HP System Replication Adapter Software QL227 features automated policy management, which simplifies the administration of data replication tasks. This allows organizations to set predefined rules for how, when, and where data should be replicated, reducing the risk of human error and ensuring consistency across environments.

In conclusion, the HP System Replication Adapter Software QL227 for VMware is an essential solution for businesses looking to improve their data replication processes. Its integration with VMware, efficient block-level replication, advanced monitoring capabilities, and compatibility with HP storage systems make it a powerful tool for enhancing data protection and ensuring business continuity. With its innovative features and user-friendly interface, QL227 stands out as a vital component for any organization aiming to secure their virtualized infrastructure.
