Thin Image workflow

Hitachi Thin Image stores snapshots in a Virtual Storage Platform G200, G400, G600 (VSP G200, G400, G600) storage system. Creating an HTI pair changes the status to “PAIR” and stores snapshot data. You can use HTI to store a maximum of 1,024 snapshots of data.

Updating the P-VOL first copies the differential data as snapshot data in pool volumes (pool-VOL) then updates the data. Snapshot data is a copy of differential data in HTI P-VOLs. If your storage system experiences a data storage failure, you can restore the data using the snapshot data in the pool.

Splitting an HTI pair saves a snapshot and stops the copying of replaced data in the pool.
