Product Description
The EMC MM5425CN512M, identified by the model MM-5425/512, is a Battery Backed PCI Card with a capacity of 512MB. This type of card is typically used in conjunction with storage controllers, particularly those employing write-back caching strategies. Its primary function is to protect data residing in the controller's volatile cache memory in the event of a sudden power failure. When a power outage occurs, the battery backup unit integrated into or associated with this card provides sufficient power to flush the contents of the cache memory to non-volatile storage (e.g., a dedicated flash module on the card itself or directly to the drives). This ensures that any data that was written to the cache but not yet committed to the physical storage media is not lost, thereby maintaining data integrity and preventing corruption. This PCI card connects to the system's PCI bus, allowing it to communicate with the host system and the storage controller. The 512MB capacity indicates the size of the volatile cache it is designed to protect. Such components are critical in enterprise storage environments where data loss can have severe consequences.
