SIOS LifeKeeper for Windows

The flexibility to build SAN and SANless clusters for Windows environments on physical servers, virtualized servers and in cloud.

LifeKeeper for Windows is a tightly integrated combination of high availability failover clustering, continuous application monitoring, data replication, and configurable recovery policies. You get 99.99% availability and disaster recovery for applications running on Microsoft Windows Server in physical, virtual, and cloud, hybrid cloud and multicloud environments.

Configuration Flexibility

SIOS provides the flexibility to build your choice of SAN and SANless clusters using a wide array of storage devices such as direct attached SCSI, iSCSI, and Fibre Channel and configurations. LifeKeeper delivers real-time, continuous replication, and fast, efficient disaster recovery across a WAN or cloud region  for complete protection for essential Windows applications. Standby servers can be either local or remote, supporting both high availability and disaster recovery configurations. Use SIOS Protection Suite on premises, in cloud, or multi-cloud.

Protecting Applications in the Cloud

LifeKeeper provide the protection you need to run essential applications in Amazon Web Services (AWS) EC2, Microsoft Azure, and Google Cloud Platform cloud without sacrificing performance, availability, or disaster recovery. It enables failover of application instances across both cloud availability zones and regions for protection from sitewide and regional disasters.

In-depth Monitoring for Complete Protection

Unlike other solutions that only monitor server operations, LifeKeeper monitors the health of the entire application environment including: network, storage, operating system, database, application software and server hardware.

Application-Specific Intelligence for Automated, Reliable Failover

LifeKeeper is bundled with SIOS application recovery kits (ARKs) for a host of essential applications, including SQL Server, Oracle Database, Postgres SQL, and SAP HANA. ARKs provide application-specific intelligence for simplifying setup, automating manual tasks and orchestrating failover in compliance with application best practices.

Minimizing Failovers with Intelligent Restart

LifeKeeper speeds recovery and reduces the need for failover by automatically attempting to restart a failed application on the primary server. It initiates failover to the standby server only when restart is unsuccessful.

SIOS SANless Clusters

Use LifeKeeper for Windows to create a SANless cluster using local attached storage on both the primary and standby servers. LifeKeeper is bundled with SIOS DataKeeper, which provides network efficient, host-based, block level replication. DataKeeper synchronizes local storage using real-time replication for failover and disaster protection without the cost and single point of failure risk of a SAN-based cluster. You may also create many real-time copies through one-to-many replication.

Use SIOS Protection Suite efficient data replication for fast, orderly data migration or relocation to new VM.

WAN Optimized for Performance

SIOS clusters use block replication and integrated WAN acceleration to achieve optimal throughput, regardless of the speed or latency of the WAN link, without the need for hardware-based WAN accelerators. Nine levels of compression and bandwidth throttling deliver the perfect balance of WAN efficiency, host workload and data throughput to meet your environment and data protection requirements.

The Target Snapshots feature ensures high performance is not impeded by reporting point-in-time access to run reports from a secondary node.  This feature offloads workloads that can decrease the performance of the primary node, and gives you faster queries, better resource utilization, and a more satisfying end-user experience.

Fast, Easy DR Testing and Zero Downtime Maintenance

The software allows administrators to easily perform switchover from primary to secondary node(s_ at the disaster recovery site for testing. This feature allows you to keep applications in service in the primary node while completing DR testing by simply unlocking the target data and bringing the application into service on the backup system. Confirm the recoverability of your apps and data and perform upgrades and maintenance with minimal impact to your production network.
