PowerMaxOS supports adding Embedded NAS (eNAS) to existing arrays non-disruptively. The Dell upgrade planning process will determine if eNAS can simply be added to an existing configuration or if additional hardware will also be required to provide adequate capacity, cache, and processing power.
The PowerMaxOS Q3 2020 release introduces the ability for eNAS code to be upgraded independent of PowerMaxOS. eNAS-only upgrades are performed remotely by the RCM team.
