NVSRAM is random access memory (RAM) that does not lose data stored in its memory when power to the storage system is disrupted. Unlike dynamic random access memory (DRAM), NVSRAM keeps its data without constantly refreshing. NVSRAM is preferred to DRAM because NVSRAM offers faster memory access times. NVSRAM also contains RAID controller module firmware that specifies default settings for the RAID controller module.
NVSRAM contains storage system parameters that determine how the storage system reports vendor and product ID information. NVSRAM also defines the behavior of the storage system. For example, NVSRAM provides the following features:
You can download NVSRAM with the Firmware Upgrade Utility or through the PowerVault Modular Disk Storage Manager.
