Unified Storage & Server Hyper-Converged Appliance

USS™ is the ideal hyperconverged  ” ALL IN ONE infrastructure solution”  to consolidate all of your server + Storage + Network  into one easy to manage appliance.

Use of embedded virtualized operating systems such ESXi or HyperV integrated with SAN Storage Controller allows for complete hardware utilization and  substantial  reduction  in Capex & Opex.

USS flexibility replaces the “fixed hardware model” of the past with on-demand resource allocation (such as CPU, memory, storage, etc.) based on your application needs.
