Chapter 1: Introduction

This guide documents the following Broadcom® MegaRAID® cache backup products used with MegaRAID SAS
high-performance SAS+SATA RAID controllers to protect cached data:

 CacheVault™ flash module (CVFM)

–CVFM04

 CacheVault power modules (CVPMs)

– CVPM02
– CVPM05

The memory modules protect the integrity of cached data on MegaRAID controllers by offloading the cached data to
nonvolatile flash memory if a complete AC power failure, or a brief power outage, occurs. These products provide an
alternative to using an uninterruptible power supply (UPS), or a second level of fault tolerance when used with a UPS.

This guide describes the backup products, including installation instructions and technical specifications.

1.1 Cache Backup Benefits

The cache memory available on MegaRAID controllers improves overall system performance because writing data to the
controller's cache memory is much faster than writing it to a storage device. Write ope rations appea r to complete quickly at
the software application level. The MegaRAID controller writes the cached data to the storage device when system activity
is low or when the cache gets full.

The risk of using write-back cache is that the cached data can be lost if the AC power fails before the data is written to the
storage device. To eliminate this risk, the MegaRAID con troller supports an energy backup solutio n to ensure no data is lost
during power or system failure. The cached data is offloaded to flash, which is restored when power resumes.

1.2 CacheVault Modules

CacheVault technology consist of two primary items. The CVPM is an ultracapacitor -based energy source that powers the
critical adapter components in the event of a power loss, long enough to offload cached data to the nonvolatile flash memory
on the CVFM. The DRAM contents are restored to the CVFM the next time the MegaRAID controller is powered, and the
cached data is written to the storage devices. The CVPM is also sometimes referred to as a supercapacitor or flash backup
unit (FBU).

CacheV ault flash technology virtually eliminates the hardwa re maintenance associated with batteries, offers lower total cost
of ownership over the life of the controller , and provides more environmentally friendly cache protection, all while maintaining
optimal RAID performance.

The following table describes the cache protection options for each MegaRAID adapter.

Chapter 2: Install the Cache Backup Products

This chapter explains how to connect the CacheVault module to back up power units.

CAUTION! Electrostatic discharge (ESD) can damage the modules and the MegaRAID controllers. Always ground yourself,

and use a ground strap before you touch the MegaRAID controller or the module. Perform all installation work
at an ESD-safe workstation that meets the requirements of EIA-625, Requirements for Handling Electrostatic
Discharge Sensitive Devices. Follow the ESD-recommended practices in the latest revision of the Inter-Process
Communication (IPC) IPC-A-610, Acceptability of Electronic Assemblies, standard.

If screws are required, use an ESD-safe Phillips screwdriver to install them. Be sure the screwdriver is centered in the screw
to avoid damaging the screw head. If you exceed the maximum torque specification, you might damage the board,
connectors, or screws, and you void the board warranty.

NOTE: To protect your data, set the MegaRAID controller Write Policy to write-through until the battery unit is charged.

After the battery unit charges, you can change the Write Policy to write-back to take advantage of data caching
performance improvements.

See Section 3.3, Handle and Dispose of CacheVault Power Modules, for information a bout how to ha ndle and dispo se of a
CVPM properly.

Chapter 3: Monitor and Manage CacheVault Modules

This chapter explains how to monitor and manage the MegaRAID CacheVault modules used with the MegaRAID
SAS controllers. You can use the following Broadcom MegaRAID utility programs to retrieve status information for CVPMs
used with MegaRAID controllers:

Storage Command Line Tool (StorCLI)

The command line management software designed for the MegaRAID product line.

Human Interface Infrastructure (HII) configuration utility

A tool for configuring controllers, physical disks, and virtual disks, and for performing other configuration tasks in a
pre-boot, Unified Extensible Firmware Interface (UEFI) environment.

For more information about CacheV ault functions in these utilities, refer to the MegaRAID SAS Software User Guide, which
applies to 6Gb/s MegaRAID controllers, or the 12Gb/s MegaRAID SAS Software User Guide for 12Gb/s MegaRAID
controllers.

3.1 Monitor CacheVault Module Information in StorCLI

The StorCLI utility supports the following CacheV ault command, which identifies the specific controller to which a CacheV ault
module is connected:

storcli /cx/cv show all

The object identifier /cx/cv refers to the CacheVault module on controller x. Only one CacheVault module can connect to
a controller at a time.

NOTE: This command works only when a CacheVault module is connected to the controller; otherwise, an error

message appears.

Input example: storcli /c0/cv show all
where, c0 identifies controller number 0.

3.2 Monitor CacheVault Module Information with the HII Configuration

Utility

You can use the HII Configuration utility to display information about the CVPM on the following Battery Management
screen. <SuperCaP> in the Type field refers to the CVPM.

Figure 9 HII Battery Management Screen

3.3 Handle and Dispose of CacheVault Power Modules

The CVPM02 module and the CVPM05 module are power modules that contain individual supercapacitors, which are
low-voltage devices, but can deliver extremely high currents especially in short-circ uit situations. Handle the supercapacitors
in an uncharged state.

The following statements are general safety considerations.

 Supercapacitors can vent or rupture if overcharged, reverse charged, incinerated, or heated above 150°C.
 Do not crush, mutilate, nail penetrate, or disassemble.
 High case temperature (burn hazard) can result from abuse of th e supercapacitor.

In the event the packaging of an individual capacitor is compromised, either by puncturing or crushing, a very limited amount
of electrolyte fluid will be released. If the product is found to be leaking (identified by a white salt crystal formation on product),
remove it from the system. A leaking capacitor will eventually increase in resistance or could cause long-term corrosion of
interconnects. Incidental contact with the white salt residue is not harmful, although it should not be ingested. Take normal
precautions after contact, which includes washing hands.

Supercapacitors are composed of aluminum, carbon, pa pe r, and an organic electrolyte. Supe rcap acito rs contai n no heavy
