Rocket iCluster high availability/disaster recovery (HA/DR) solutions ensure uninterrupted operation for your IBM i applications, providing continuous access by monitoring, identifying, and self-correcting replication problems. iCluster’s multiple-cluster administration console monitors events in real-time on the classic green screen and the modern web UI. Rocket iCluster reduces downtime related to unexpected IBM i system interruptions with real-time, fault-tolerant, object-level replication. In the event of an outage, you can bring a “warm” mirror of a clustered IBM i system into service within minutes. iCluster disaster recovery software ensures a high-availability environment by giving business applications concurrent access to both master and replicated data. This setup allows you to offload critical business tasks such as running reports and queries as well as ETL, EDI, and web tasks from your secondary system without affecting primary system performance.

HPE Serviceguard for Linux (SGLX) is a high‑availability (HA) and disaster‑recovery (DR) clustering solution designed to maximize uptime for critical Linux workloads, on‑premises, in virtualized environments, or across hybrid and public clouds. It continuously monitors applications, services, databases, servers, networks, storage, and processes; upon detecting faults, it performs fast, automated failover, often within four seconds, without compromising data integrity. SGLX supports both shared‑storage and shared‑nothing architectures (via its Flex Storage add‑on), enabling highly available SAP HANA, NFS, or other services even where SAN isn’t available. The HA‑only E5 edition delivers zero‑RPO application failover with robust monitoring and a workload‑centric GUI, while the HA + DR E7 edition adds multi‑target replication, automated and push‑button site recovery, DR rehearsal, and workload mobility across on‑premises and cloud.
