MM-5435CN 16GB 64-bit/66MHz Battery Backed NVRAM PCI Memory Card

** Tier I/II OEM Product **
This is an OEM product not sold through distribution channels.


The MM-5435CN can be integrated into storage filers, servers and controllers that have an available PCI slot. Non-volatile memory is mapped to PCI memory space, which easily creates a separate and distinct memory partition for functions such as journaling and caching. The card has been specifically designed to provide dramatic improvements in applications that are I/O bound. In particular, applications that involve file journaling, sequential logging, or frequent disk I/O’s such as transaction processing, file serving, and data warehousing can benefit significantly by implementing solid state NVRAM on the PCI bus.

The MM-5435CN is a full length PCI card with a 64-bit/66MHz PCI interface and 2GB to 16GB of NVRAM. Redundant, rechargeable lithium ion batteries are on-board to provide data retention in the event of a power loss. Status LED lights are software programmable and battery status registers in the CSR can be enabled to monitor battery voltages. The battery circuitry and failover have been refined over twenty-five years of product development to ensure the utmost in data retention and availability.

Because the MM-5435CN resides on the PCI bus, I/O transfers to memory are only limited by bus speeds instead of a cable interlink which usually has significant latency. The card’s non-volatility features also enable data to be retrieved after a power failure or system reset. Because the card utilizes solid state memory, there is no head seek time as experienced with rotating storage media. This, combined with the card’s data retention capabilities, make the MM-5435CN the ideal solution for journaling and caching.
