Multiple SC Series arrays may be deployed in federated configurations using the Live Migrate feature included with firmware version 7.1 and above (7.3 and above for SCv2000 Series.) Transparent, non-disruptive volume movement among arrays is enabled, allowing the combined capacity and cache of the entire federated cluster to be seamlessly utilized for maximum performance and scalability in expanding data centers. For example, a cluster of ten SC9000 arrays can provide a total of 10,240 drives (up to 60PB raw capacity) with over 5TB of system memory.
