IT architects needing a solution to deliver high availability and disaster recovery for mission-critical applications
About SIOS DataKeeper
SIOS DataKeeper is a host‑based, block‑level replication solution that delivers real‑time, synchronous or asynchronous redundancy for Windows Server environments, integrating seamlessly with Windows Server Failover Clustering (WSFC). It enables "SANless" clusters—eliminating dependency on shared‑storage arrays—by replicating data across local, virtual, or cloud servers, including VMware, Hyper‑V, AWS, Azure, and Google Cloud Platform, while offering optimized performance without requiring hardware accelerators or compression devices. Once installed, it provides a new SIOS DataKeeper Volume resource in WSFC, supporting geographically dispersed clusters via cross‑subnet failover and configurable heartbeat parameters. Built-in WAN optimization and efficient compression maximize bandwidth use over local and wide‑area networks.

DxEnterprise
DxEnterprise Smart High Availability is an infrastructure-agnostic software solution that simplifies management and network security for mission-critical SQL Server workloads across modern hybrid and multi-cloud environments. It frees organizations from vendor lock-in and gives them the power to create SQL Server Availability Group clusters containing any mix of OSes, containers, virtual machines, bare-metal, and cloud servers. Organizations unlock:
- Granular database-level monitoring with intelligent automated failover
- Nearest-to-zero SQL Server downtime for Windows, Linux, and containers
- Easy stretch clusters across sites and clouds for robust disaster recovery
Built-in Zero Trust Network Access tunneling allows users to securely deploy HA clusters that span from anywhere, to anywhere, without VPNs or direct links.
DxEnterprise also comes standard with DxOperator by DH2i, Microsoft’s preferred Operator for Kubernetes (K8s) SQL Server deployments.

SIOS LifeKeeper
SIOS LifeKeeper for Windows is a comprehensive high-availability and disaster‑recovery solution that integrates failover clustering, continuous application monitoring, data replication, and flexible recovery policies to deliver 99.99 % uptime for Microsoft Windows Server environments—whether physical, virtual, cloud, hybrid‑cloud, or multicloud. Administrators can build SAN‑based or SANless clusters using a variety of storage types (direct‑attached SCSI, iSCSI, Fibre Channel, or local disk) and choose between local or remote standby servers that support both high availability and disaster recovery. LifeKeeper offers real‑time block‑level replication via bundled DataKeeper, with WAN‑optimized performance that includes nine levels of compression, bandwidth throttling, and integrated WAN acceleration, ensuring efficient replication across cloud regions or over WAN without hardware accelerators.

HPE Serviceguard
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.

OpenText Availability
OpenText Availability continuously replicates physical, virtual, and cloud systems at the byte level, capturing real-time changes with a Recovery Point Objective of seconds, and maintains duplicated Windows and Linux servers at secondary locations for near-zero downtime. In the event of an outage, it offers automated or on-demand failover with integrated heartbeat monitoring and DNS management, followed by seamless failback when systems are restored. Data is secured with AES 256-bit encryption in flight, while three tiers of compression and bandwidth-throttling options minimize network impact. An extensive API allows integration with other applications, and built-in alerting, reporting, and non-disruptive failover testing ensure administrators can monitor health, troubleshoot, and validate disaster-recovery plans without affecting production workloads. OpenText Availability supports any hypervisor, including VMware ESXi/vSphere and Microsoft Hyper-V, and any major cloud platform.
