SIOS DataKeeper is a block-level replication solution tailored for host-based environments, providing real-time redundancy either synchronously or asynchronously for Windows Server setups, and it integrates effortlessly with Windows Server Failover Clustering (WSFC). This innovative solution facilitates the creation of "SANless" clusters, removing the need for shared-storage systems by enabling data replication across various local, virtual, or cloud servers such as VMware, Hyper-V, AWS, Azure, and Google Cloud Platform, all while ensuring optimized performance without the necessity for specialized hardware accelerators or compression tools. After installation, it introduces a new SIOS DataKeeper Volume resource within WSFC, allowing for the support of geographically distributed clusters through cross-subnet failover and customizable heartbeat settings. Additionally, it features built-in WAN optimization and effective compression to enhance bandwidth utilization over both local and wide-area networks, thereby improving overall network efficiency. This combination of features makes SIOS DataKeeper an excellent choice for organizations looking to enhance their data availability without the complexities of traditional storage solutions.

SIOS LifeKeeper for Windows is an all-encompassing solution designed for high availability and disaster recovery, seamlessly combining features like failover clustering, continuous monitoring of applications, data replication, and adaptable recovery policies to achieve an impressive 99.99% uptime for various Microsoft Windows Server environments, including physical, virtual, cloud, hybrid-cloud, and multicloud setups. System administrators have the flexibility to construct SAN-based or SANless clusters utilizing multiple storage options, such as direct-attached SCSI, iSCSI, Fibre Channel, or local disks, while also selecting between local or remote standby servers that cater to both high availability and disaster recovery requirements. With its real-time block-level replication capabilities provided through the integrated DataKeeper, LifeKeeper offers WAN-optimized performance, which features nine distinct levels of compression, bandwidth throttling, and built-in WAN acceleration, guaranteeing effective data replication across different cloud regions or over WAN networks without relying on additional hardware accelerators. This robust solution not only enhances operational resilience but also simplifies the management of complex IT infrastructures. Ultimately, SIOS LifeKeeper stands out as a vital tool for organizations aiming to maintain seamless service continuity and safeguard their valuable data assets.

Our Libelle BusinessShadow solution offers a robust approach to disaster recovery and high availability by enabling the mirroring of databases and application systems with a controlled time delay. This innovative solution safeguards your organization against not only hardware failures and application glitches but also elemental disasters, sabotage, and accidental data loss. Central to this system is our patented time funnel, which efficiently holds change logs prior to their transfer to the standby system. This design allows for a seamless and rapid transition to the standby setup during errors or maintenance tasks, ensuring minimal disruption. By leveraging the time funnel, you can swiftly revert to an error-free state without the cumbersome process of restoring from backups. Notably, your data remains consistently up to date, as it is temporarily preserved in the time funnel rather than relying on outdated backup copies. This solution not only enhances resilience but also streamlines operations, providing peace of mind in the face of potential disruptions.
