Both PowerMax 2500 and 8500 platforms are based on a modular design that makes it easier for field personnel to add or remove components as required, providing greater flexibility and scale.
As in previous generations, redundant components span the array to ensure that the system stays online 24x7x365. Field Replaceable Units (FRUs) ensure seamless hot swap-out capabilities in case of component failure.
Non-disruptive upgrades allow the system software (PowerMaxOS) to be upgraded online with no impact to operations.
Both systems are remotely monitored and ‘dial home’ using the Secure Connect Gateway to Dell Technologies where corrective action takes place depending on the event code.
