Concepts

Remote Block Storage is a high-performance, scalable, and resilient storage solution designed for modern enterprise environments. It provides virtual block devices that can be attached to multiple instances, enabling seamless data access with low latency and high availability.

With built-in redundancy and self-healing capabilities, Remote Block Storage ensures data integrity and fault tolerance, making it ideal for mission-critical workloads. Its dynamic scalability allows businesses to expand their storage infrastructure effortlessly while optimizing performance and cost efficiency.

Perfect for databases, virtual machines, and high-throughput applications, Remote Block Storage delivers enterprise-grade performance with the flexibility of cloud-native architecture.

The servers.com Remote Block Storage (RBS) is a scalable and multi-tenant solution running on Ceph and communicating with your hosts by the iSCSI protocol. This service is compatible with servers.com Dedicated Servers and Kubernetes nodes.

A volume is a block storage device at your disposal that you can mount to your hosts. Each volume consists of the following characteristics:

• Size = disk space at your disposal
• The maximum IOPS value (input/output operations per second) is the maximum number of read and write operations performed by the disk per second
• The maximum bandwidth is the total number of bytes that can be read from or written to the disk per second.

The service is flavor-based by uniting IOPS and bandwidth characteristics into types. Each volume is assigned with a private IP address. This address is called a Volume IP address.

For best performance, Remote Block Storage volumes should be used with 4KB block sizes, as the underlying storage is optimized for 4KB-aligned I/O operations.

Use case

Remote Block Storage can be integrated with your servers.com Kubernetes cluster covering needs in a persistent storage solution. Thus, you can keep unimportant information within a local storage on a Kubernetes node and let RBS to store your vital data.
