StorSimple's Cloud-integrated Storage (CiS) has been helping customers do this for over a year now and proven it's mettle working in the data centers of large
enterprises. CiS on-premises SAN storage exports iSCSI LUNs to servers and connects on the back, or device, side to enterprise cloud storage for storing
snapshot, backup, archive and unstructured, dormant data. CiS is a hybrid SAN array having flash SSDs and hard disk layers but it adds a third slower, higherlatency enterprise cloud storage storage layer. It’s 3-tier design is perfectly matched for managing the masses of unstructured data that IT workers wrestle with.
