EMC Data Domain 2GB LP (Low Profile) PCI-e NVRAM Card, identified by part number X-NVRAM1GL1, is a crucial component designed for use with Data Domain storage systems, specifically the DD160 and DD620 models. This card serves as Non-Volatile Random Access Memory (NVRAM) storage, providing high-speed, battery-backed cache for the Data Domain system. The NVRAM card helps improve system performance and data integrity by temporarily caching data during write operations, ensuring that critical data is safely stored in case of unexpected power loss or system failure.
