Block storage provides additional storage space that can be used with a cloud server. Each block storage consists of an SSD that can be individually customized to the right size. Because block storage is handled in the same way as individual data carriers, it is suitable to use for saving files, databases or log files, etc.
Block storage is only accessible once it has been assigned to a cloud server. Block storage can only be assigned to a single cloud server. If more storage space is needed for your cloud server, you can adjust the size of your block storage at any time. Alternatively, you can create additional block storage and assign it to your cloud server.
Please note: Block storage must be set up separately for each data center. For example, if you have set up a cloud server in a data center in the USA, you can only assign block storage that is hosted in the same data center to this server.
When you create block storage and assign it to a cloud server, you have to adjust the configuration of the data storage medium in your server's operating system. You also have to adjust the data configuration if you change the size of the block storage at a later time. Depending on your operating system, it may be necessary to adjust the configuration after assigning the block storage to a different cloud server.
If you have combined the boot partition and block storage into one volume and you delete the block storage or assign it to a different server, inconsistencies in the file system can arise. Before deleting or assigning block storage, make sure that the data on it is not needed by an application and the block storage is not part of a volume.
