Why powerstore snapshots technology not employing the xtremIO tree based snapping instead of copy-on-write
XtremIO array has efficient tree based snapshot technology. The next mid range array powerstore is using traditional approach to take snapshots not the tree based approach. Kindly let us know the drawback of tree based snapshots and why it is not used in powerstore?

Different products in Dell's portfolio have different design goals and the architectural choices are made accordingly. One of the design goals with PowerStore’s architecture is being able to scale to large capacity points within a single appliance. We optimize performance and resource usage by doing a copy on first write for the metadata blocks (not data blocks) as part of the snapshot implementation.
