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
The Elastic Volume Service (EVS) offers robust and reliable block storage designed for cloud servers, including Elastic Cloud Servers (ECS) and Bare Metal Servers (BMS). With an impressive durability rate of 99.9999999% and minimal read/write latency of around 1 millisecond, EVS caters to a diverse array of mission-critical applications. Users can select from a variety of EVS disks, including options for high I/O, general-purpose SSD, or ultra-high I/O, ensuring that there is a suitable solution available at a competitive price point. Additionally, EVS allows for seamless expansion of storage capacity without causing any service interruptions, making it easy to adjust to changing storage needs. Should an EVS disk reach its limit, users can promptly increase their block storage, even while the disk is actively in use, enabling a smooth scaling process. Within a few simple clicks, the capacity of system disks can be expanded up to 1 TB, while data disks can be scaled to as much as 32 TB, ensuring ongoing support for your workloads. Furthermore, the data stored on EVS disks benefits from encryption through the industry-standard AES-256 algorithm, guaranteeing high levels of security for sensitive information. This comprehensive service provides both reliability and flexibility, making it an excellent choice for businesses aiming to optimize their cloud storage solutions.
