CacheVault™ Flash Module, CVFM03, and the CacheVault Power
Module, CVPM02. The CacheVault modules provide on-board memory and power backup to protect cache data.
Before you install your CacheVault modules, take a few minutes to read this quick installation guide. This guide
describes the CacheVault modules, and it documents how to attach the CVFM03 module to a RAID controller, and
then connect the CVFM03 module to the CVPM02 module. If you need more information about any topic covered in
this guide, refer to the related documents on your MegaRAID Universal Software Suite CD.
1 Product Overview
The MegaRAID SAS 9265CV-8i RAID controller supports the CVFM03 module, which provides on-board memory to
protect cache data. The CVFM03 module connects by cable to a remote CVPM02 module. The CVPM02 module is a
super-capacitor pack that provides power to offload cached data from the DRAM to the nonvolatile Flash memory on
the CVFM03 module if a power failure or outage occurs. The DRAM contents are then restored to the CVFM03 module
the next time the RAID controller is powered on. Cached data can then be written to the storage devices.
The MegaRAID SAS 9265CV-8i RAID controller is a SAS2208 RAID-on-Chip (ROC)-based, PCIe® 3.0 internal RAID Host
Bus Adapter (HBA) with internal HDD connectors and nonvolatile memory module with cache offload.
1.1 CacheVault Module Descriptions
The CVFM03 module is an on-board 1-GB DDR3 1333 MT/s CacheVault Flash Module, plus 2 GB of NAND flash memory
that can store the cache contents in case of power loss, capacitor charge maintenance, and capacitor health
monitoring functions. You can attach the CVFM03 module directly to the RAID controller and connect it by cable to a
remote CVPM02 module.
The CVPM02 module is a super-capacitor pack that provides the power to offload cached data from the DRAM to the
nonvolatile Flash memory on the CVFM03 module if a power failure or outage occurs. The CVPM02 module is installed
on a remote mount board by using the included CVPM02 clip.
For more information about the CacheVault Flash Memory Module and the CacheVault Power Module, refer to the
Cache Backup Products for MegaRAID SAS+SATA RAID Controllers User Guide on the MegaRAID Universal Software Suite
CD.
