HP offers a comprehensive portfolio of disaster-tolerant solutions (DTS) to protect your data in the event of disaster or system failure. All of the solutions build on HP’s foundation clustering software, HP Serviceguard, and run on HP Integrity and HP 9000 servers. The portfolio includes HP Extended Distance Cluster, HP Metrocluster, and HP Continentalclusters.
While these solutions may differ in their specific components, their objective is the same: to protect users from site-wide outages. To achieve this goal, all these solutions utilize multiple data centers and multiple copies of users’ data so that if one data center fails, a second data center is available to continue processing.
Key Features
- Extended Distance Cluster is a host-based data replication configuration that can span up to 100 km.
- Metrocluster offers real-time infrastructure with automatic failover and failback of mission-critical applications between data centers.
- Continentalclusters feature bi-directional, push-button failover, giving IT staff complete control over when to initiate failover.
- All solutions offer access to on-demand capacity and the policy-based HP-UX Workload Manager.
- The solutions support a wide range of data replication offerings.
Benefits
- Businesses are able to meet stringent recovery point objectives (RPOs) and recovery time objectives (RTOs).
- Computing resources remain available, even during critical conditions.
- Application downtime is reduced through fast application failover time, and planned downtime is reduced through rolling upgrades
- Critical data is protected, resources can be pooled, and the recovery process can be easily tested.
