In my opinion, the best features of Hitachi TrueCopy include its ability to act similarly to a snapshot from any disk, from any LUN, and for fast data copying from production to test. We use Hitachi TrueCopy and Thin Image. Hitachi TrueCopy allows us to transfer data from one storage to another, for example, when we buy new storage, we transfer data, LUNs, and disks from one storage to another, and we also use Hitachi TrueCopy to transfer data from one site to another site. We transfer data through iSCSI. The Hitachi TrueCopy ability to customize replication strategies is a very useful tool for replication.
