SSD caching available as an option adds up to 12 TB of management-free high-performance data caching capability to the entire array. This system implements NAS based protocols over a large-scale global name space. Today the system can scale out using commodity components to 30 balanced nodes and up to Storwize systems are capable of external virtualization, ideally used for technology migration and investment protection for aging systems. Storwize advanced caching, free-of-charge Easy Tier automatic data placement and automatic hotspot elimination help infuse a second life to previous-generation storage systems. Modern virtualization functions like inline real-time compression for data on external systems can help delay capacity repurchase for several years.
