The EMC MM5428CN1G is a 1GB Non-Volatile RAM (NVRAM) PCI Interface Card specifically designed to enhance the data integrity and performance of EMC DD660 and DD690 data domain deduplication storage systems. This card plays a vital role in the data protection strategy of these systems by ensuring that data is safely stored in the event of a sudden power loss or system failure. The card achieves this by storing in-progress data in its non-volatile memory, allowing for subsequent recovery and ensuring that no critical data is lost. The inclusion of the MM5428CN1G NVRAM card in EMC’s data domain systems considerably accelerates the deduplication process. This is because the card temporarily stores unique data segments before they are deduplicated, reducing the amount of time required for data to be processed and written to disk. The high-speed PCI interface ensures seamless integration with the DD660 and DD690 systems, offering a robust solution for businesses that require reliable, high-performance data protection capabilities. With its advanced technology, the EMC MM5428CN1G NVRAM card is indispensable for organizations aiming to achieve high levels of data integrity and availability in their storage infrastructures.
