SteelFusion Core –  A storage delivery controller in the datacenter that interfaces with a storage area network (SAN) to project centralized data out to branches. SteelFusion serves as the infrastructure for your branch, significantly lowering capital and operational costs, mitigating the risk of branch disasters, and improving IT’s responsiveness to the business.

A physical or virtual Core is deployed in the data center alongside SteelHeads and a storage array. The Core mounts logical unit numbers (LUNs) provisioned for the branch offices from a storage array and manages block transfers between these LUNs and Edges. At the data center, the Core integrates with existing storage systems and SteelHead implementations and connects dedicated LUNs with each Edge at the branch office.

SteelFusion Edge (includes xx60 model appliances)-  converged appliance that integrates server, storage, network, and virtualization to run local branch applications, eliminating the need for additional branch infrastructure.

A standalone or high-availability Edge is deployed in the branch and presents the LUNs mounted on the Core at the branch through iSCSI targets. The Edge can also host local LUNs without a Core connection.
