HP Metrocluster is a business continuity solution with automatic site failover for up to 16 HP Integrity or HP 9000 servers connected to array-based storage. It is built upon HP’s foundation clustering software, HP Serviceguard, providing the highest levels of availability and business continuity for enterprise data centers.
Metrocluster supports several array-based data replication offerings:
- HP Continuous Access XP (CA XP)
- HP Continuous Access EVA (CA EVA)
- EMC Symmetrix Remote Data Facility (EMC SRDF)
The functionality of each of these Metrocluster offerings is comparable with the exception of the specific disk array supported. For instance, HP Metrocluster with CA EVA only supports HP StorageWorks EVA disk arrays, using CA EVA for data replication.
Key Features
- Integrated with the array-based Continuous Access Enterprise Virtual Array (CA EVA), Continuous Access XP (CA XP), or EMC Symmetrix Remote Data Facility (EMC SRDF)
- Automatic and bi-directional failover of business-critical data and applications located up to 300 km apart – so both data centers can be active, protected, and capable of handling application failover for each other
- Access to on-demand capacity and the policy-based HP-UX Workload Manager
- Metrocluster Continuous Access XP can failover to Continentalclusters for the ultimate in data protection. This solution offers cascading failover from metrocluster to continentalclusters. The metroclusters failover within minutes and then can be cascaded to a continentalcluster failover as needed
Benefits
- Customers are able to meet stringent recovery point objectives (RPOs) and recovery time objectives (RTOs).
- Computing resources remain available.
- Application downtime is reduced through fast application failover time.
- Planned downtime is reduced through rolling upgrades.
- Critical data is protected through replication of dynamic data.
When Metrocluster is appropriate
- Array-based data replication is the preferred approach for storing and managing large volumes of data.
- Business requirements mandate 24x7 data availability and applications must be restored minutes after an outage.
- Industry and government regulations require a recovery site.
