SmartPools enables automatic migration of data up and down the different tiers within an PowerScale cluster – all within a single volume. Different node-types can be used for each tier to provide multiple tiers based on performance/capacity requirements. Data migration policy is configured by each customer, allowing for maximum flexibility and customization. This makes it easy for an administrator to optimize the performance and cost profile for every file. A common application for SmartPools in EDA is to automate migration of project data to lower-cost storage (including archive) after a project has tape-out. Moving data back from lower-cost storage can also be automated. This would be useful should a project need restored due to unexpected chip revisions, or to develop a next-generation chip. Behavior is controlled by policy, can be based on last time accessed (for example), and is fully configurable by the administrator.
