MegaRAID SAS 9286CV-8eCC RAID Controller Quick Installation Guide
June 2012 MegaRAID SAS 9286CV-8eCC RAID Controller Quick Installation Guide
1.1 CacheVault Flash Module and CacheVault Power Module
The MegaRAID SAS RAID controller supports the CVFM03 CacheVault Flash Module, an on-board 1-GB nonvolatile
DDR3 1333-MT/s CacheVault Flash Module, which is a memory module that provides cache offload to protect cached
data in case of host power failure. The CVFM03 module is attached directly to the MegaRAID SAS 9286CV-8eCC RAID
controller and connects by cable to a remote CVPM02 CacheVault Power Module, which is a super-capacitor pack that
can be installed on a remote mount board (sold separately) using the included CVPM02 clip.
The CVPM02 module provides the power to off load 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 CVPM02 module is an intelligent backup power supply solution, which provides both capacitor charge
maintenance and capacitor health monitoring functions similar to those of an intelligent Battery Backup Unit (iBBU).
For more information about the CacheVault Flash Memory or 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.
1.2 MegaRAID CacheCade™ Pro 2.0 and MegaRAID Fast Path Ready
The CacheCade family of 6Gb/s MegaRAID controllers ship as standard with CacheCade Pro 2.0 and Fast Path software
enabled out of the box. These software offerings optimize application performance in direct-attached storage
environments configured with solid-state drives (SSDs). CacheCade Pro 2.0 read/write software is designed to
dramatically accelerate application I/O performance of hard disk drive (HDD)-based arrays by intelligently caching
frequently accessed, or hot spot, data to SSDs. Using SSDs as a dedicated pool of high-performance cache memory in
front of HDDs can cost-effectively improve both read and write performance, reduce I/O latencies, accelerate
application response time and lower RAID access and rebuild times. MegaRAID Fast Path software is a high-
performance I/O accelerator, designed to dramatically boost transactional application throughput of SSD arrays
connected to the MegaRAID controller card.
Refer to the MegaRAID SAS Software User Guide for CacheCade Pro 2.0 procedures.
