In hyperconvergence mode, ABS supports three storage protocol access methods (NFS, iSCSI, and vHost) tailored for different scenarios, following the principles of local-first access and automatic failover. When the ABS Chunk (Access) service on the physical node (i.e., local node) where the virtual machine resides is operating normally, the storage protocol defaults the destination to the local node. This allows data transmission between the client and ABS to be completed locally, avoiding the external network, which significantly improves performance.
If the ABS Chunk (Access) service on the local node encounters an issue, each storage protocol will automatically switch the data path to another operational storage node based on its failure detection and link adjustment mechanism, ensuring continuous and reliable data access. Once the local ABS Chunk service has returned to normal and has been running stably for some time, the system switches the data path back to the local node to continue providing optimal performance.
