Question 5

A customer has invested much time using the Dell PS Series Host Integration Toolkit (HIT) to integrate SAN snapshot protection with Microsoft SQL Server native snapshot technology. The customer expresses concern about whether Dell EMC SC Series cross-platform replication supports that capability.
What should be your response?

Recreate integration on the SC Series array and use only SC-to-SC replication for those volumes.

Leverage the integration investment and use only PS-to-PS replication on those volumes.

Cross-platform replication works with SC Series HIT integrations.

Cross-platform replication works with PS Series HIT integrations.
