Block Storage is similar to a physical hard disk. It can be used to install an operating system or hold another filesystem for a Cloud Server.Writable Block Storage and CD-ROM resources can be freely attached to any Cloud Server within the same zone and under the same account. A maximum of 16 storage devices can be attached to a Cloud Server at the same time; however, the combined limit for network interfaces and storage devices is 24.Storage resource typesThere are four different storage resource types: normal, CD-ROM, template, and backup. The normal type represents writable Block Storage.
