Explanation: PowerProtect DD High Availability configurations are supported on the DD9900 model with a single set of shared storage, ensuring redundancy and failover capabilities, critical for enterprise-level data protection environments.
PowerProtect DD High Availability (HA) configuration provides a continuous availability solution, particularly suited for DD9900 systems. Here are the two key attributes of DD HA:
* Single Set of Shared Storage: In the HA configuration, both nodes in the active/standby configuration share the same set of storage. This shared storage ensures that if the active node fails, the standby node can take over without data loss, accessing the same storage seamlessly.
* Supported Only on DD9900 Systems: The HA feature is exclusive to high-end PowerProtect DD models, specifically the DD9900. This limitation is due to the hardware requirements needed to support the robust failover and data redundancy capabilities inherent in an HA setup.
