What is Volume Block Storage?

Create and attach additional volume block storage to your instances using the GB Cloud Block Storage Volume service. These storage volumes exist independently of instances, yet they can be readily moved from one to the next without having to reboot. The attached volumes appear as block devices that can be formatted and mounted in the same way as any other block device. Consider them a cloud-based external drive.

With 3x synchronous replication, Block Storage Volumes are highly reliable. They’re lightning-fast, thanks to excellent engineering, NVMe/HDD technology, and a lightning-speed network. They’re cheap — $0.10 per gigabyte each month with no usage fees. They’re cloud-based, which means they’re elastic, scalable, extensible, resizable, and so on. You can create volumes ranging in size from 10 GB until more than 10,000 GB. You can hot-plug them into and out of those that are already functioning. Oh, and you can also kick them out.

How does the Volume Block Storage works?

Block storage operates by dividing storage media into fixed-size blocks, each capable of storing a portion of data. The size of these blocks is predetermined by the management system. Typically, a single block cannot accommodate an entire piece of data, so files are fragmented into multiple blocks for storage. Each block receives a unique identifier, devoid of additional metadata such as data format, type, or ownership.

The allocation and distribution of blocks across the storage network are managed by the operating system, aiming to strike a balance between efficiency and functionality. When a file is requested, the management application utilizes addresses to locate the requisite blocks and then assembles them into the complete file for access.

By facilitating storage across various environments, block storage liberates data from the constraints of individual user environments. Consequently, data can be accessed through multiple pathways to optimize efficiency, boasting high input/output operations per second (IOPS). This approach yields superior efficiency compared to alternative cloud storage methods, rendering it well-suited for high-performance applications or those necessitating continuous read-write operations.
