[Reference] Disk type
Enumeration value description
| Enumeration value | Disk type | Optional range (system disk) | Optional range (data disk) | Data Ark support |
|---|---|---|---|---|
| LOCAL_NORMAL | Ordinary local disk | When creating/reinstalling: only supports the current image size When reconfiguring [1]: current image size -100G | 20G - 2000G, default 20G | Supported, system disk and data The disk must be turned on at the same time |
| LOCAL_SSD | SSD local disk | When creating/reinstalling: only the current image size is supported When reconfiguring [1]: Current image size - 100G | 20G - 1000G, default 20G | Not supported |
| CLOUD_NORMAL | Ordinary cloud disk | (not supported) | 20G - 8000G, default 20G | Only supports data disk |
| CLOUD_SSD | SSD cloud disk | 20-500G Support creation/reinstallation/modification [2] | 20G - 4000G, default 20G | Not supported |
| CLOUD_RSSD | RSSD cloud disk | 20-500G Support creation/reinstallation/modification [2] | 20G - 32000G, default 20G | Not supported |
| EXCLUSIVE_LOCAL_DISK | Exclusive local disk | 4096G / 3072G | Not supported | Not supported |
[1] The local disk does not support passing the system disk Size > image size when creating/reinstalling the host. But after the expansion is completed, there is no need to enter the system operation.
[2] Cloud disk supports passing system disk Size > image size when creating/reinstalling a host. After the expansion is completed, you need to enter the system to expand the file system. For the operation steps, please refer to [Document](https://docs.ucloud.cn/uhost/guide/disk#Cloud Disk).
