DRBD® (Distributed Replicated Block Device) is an open source, software-centric solution for block storage replication on Linux, engineered to provide high-performance and high-availability (HA) data services by synchronously or asynchronously mirroring local block devices between nodes in real-time. As a virtual block-device driver deeply integrated into the Linux kernel, DRBD guarantees optimal local read performance while facilitating efficient write-through replication to peer devices. The user-space tools, including drbdadm, drbdsetup, and drbdmeta, support declarative configuration, metadata management, and overall administration across different installations. Initially designed to support two-node HA clusters, DRBD 9.x has evolved to accommodate multi-node replication and seamlessly integrate into software-defined storage (SDS) systems like LINSTOR, which enhances its applicability in cloud-native frameworks. This evolution reflects the growing demand for robust data management solutions in increasingly complex environments.

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.

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.
