What is the HPE Smart Storage Battery?

The HPE Smart Storage Battery is a lithium-ion, low-halogen centralized backup source and is required to back up the write cache content onto flash memory on the HPE Smart Array Gen9 and newer storage controllers in case of an unplanned server power loss.

How many batteries does a HPE smart storage hybrid capacitor need?

Only one battery is required per server as it can support multiple devices. The HPE Smart Storage Hybrid Capacitor is a battery-free technology for power storage that provides data protection for cached data while eliminating costs and environmental impact of lithium-ion batteries.

What is HPE smart hybrid capacitor?

For those running HPE Gen10 servers, the HPE Smart Hybrid Capacitor is a centralized backup power source supporting multiple controllers where the NAND flash memory on HPE Smart Array Performance Class controllers and the HPE Smart Hybrid Capacitor work together to save cached data in the event of unplanned server power loss.

How many smart storage batteries can be used per system?

In most cases, only a single Smart Storage Battery or a single Smart Hybrid Capacitor can be used per system. Please check your server platform QuickSpecs for details. Notes: The HPE Smart Storage Hybrid Capacitor is only supported on Gen10 servers or later.

What is a smart storage battery?

The Smart Storage Battery provides a sufficient duration to transfer the cached data from DDR memory to flash memory, where the data remains indefinitely or until a controller retrieves the data. For more information, see the QuickSpecs document for the Smart Storage Battery.

Can a hybrid capacitor module be used with a smart storage battery?

Please note, although the hybrid capacitor module is mechanically compatible with the 96W Smart Storage Battery (P01366-B21 and P01367-B21), the module cannot be used in combination with the Smart Storage Battery. In most cases, only a single Smart Storage Battery or a single Smart Hybrid Capacitor can be used per system.
