Description

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.

Description

Persistent Disk provides dependable and high-efficiency block storage tailored for virtual machine instances. For scenarios where bulk throughput takes precedence, HDD serves as a cost-effective storage solution. Conversely, SSD ensures consistently superior performance for both random-access tasks and bulk throughput demands. Each of these storage types can be expanded up to a capacity of 64 TB. Thanks to multi-reader mounting capabilities, numerous virtual machines can simultaneously access data from a single Persistent Disk without experiencing a drop in aggregate performance or incurring additional costs. You no longer need to fret about the potential downsizing of your block devices; Persistent Disk offers unparalleled flexibility by enabling you to adjust your storage size even while in operation across one or more virtual machines, all without any downtime. For enhanced convenience and adaptability, snapshots are automatically geo-replicated and readily available for restoration across all regions. Additionally, the process for creating snapshots of a block device can be completed in just minutes instead of lasting hours. To ensure data security, Persistent Disks are automatically encrypted, safeguarding your information both during transmission and while stored. With these features combined, Persistent Disk stands out as a robust solution for managing storage needs effectively.
