Disk CSI Plugin support Cloud disk provision and attachment. And Cloud disk is type of block storage, can only used as ReadWriteOnce mode. Only be attached to one node at the same time.
More detail information please refer to Cloud Disk.
NAS CSI Plugin can support NAS volume provision and mount. Alibaba Cloud Network Attached Storage (NAS) storage is type of network storage which compatible with multiple standard protocols, such as NFS and SMB, and can be mount by multi nodes at the same time.
More detail information please refer to NAS.
CPFS CSI Plugin can support CPFS volume provision and mount. Cloud Paralleled File System (CPFS) is a parallel file system, and can be mount by multi nodes at the same time.
More detail information pls refer to CPFS.
OSS CSI Plugin support OSS bucket mount, but does not support provision volume. OSS storage is type of object storage and can be mount by multi nodes at the same time.
More detail information pls refer to OSS.
LVM CSI Plugin support LVM volume provision and mount. LVM volume is a type of local storage and should not be used in high availability scenario.
