Cache Backup Products for MegaRAID SAS+SATA RAID Controllers User Guide
May 2015
Chapter 1: Introduction
This guide documents the Avago® family of MegaRAID® cache backup products that are used with its
high-performance MegaRAID SAS+SATA RAID controllers to protect cached data. It describes the products,
documents the installation instructions, and provides the technical specifications.
The cache backup products documented in this guide include the following:
intelligent Battery Backup Units (iBBU units)
intelligent Transportable Battery Backup Units (iTBBU units)
Transportable Memory Modules (TMMs)
RAID Cache Module (RCM01)
CacheVault® Flash Modules (CVFMs)
CacheVault Power Modules (CVPMs)
1.1 Overview
The battery backup units and the memory modules protect the integrity of the cached data on MegaRAID controllers
by providing backup power if there is a complete AC power failure or a brief power outage. These products provide an
alternative to using an uninterruptible power supply (UPS), and a second level of fault tolerance when used in
conjunction with a UPS.
Chapter 1: Introduction
Overview
1.1.1 Benefits
The cache memory available on MegaRAID controllers can improve overall system performance, because writing data
to the controllers cache memory is much faster than writing it to a storage device. Write operations appear to
complete very quickly at the software application level. The RAID controller then writes the cached data to the storage
device when system activity is low or when the cache is getting full.
The risk of using write-back cache is that the cached data can be lost if the AC power fails before it has been written to
the storage device. You can use an onboard transportable memory module in conjunction with an iBBU unit or a
CVPM module, and a CVFM module in conjunction with a CVPM module to eliminate this risk.
1.1.2 Intelligent Battery Backup Units
An intelligent BBU unit has built-in functionality to charge the battery pack automatically and to communicate battery
status information such as voltage, temperature, and current to the host computer system.
The MegaRAID iBBU units monitor the voltage level of the DRAM modules on MegaRAID controllers. If the voltage
drops below a predefined level, the battery backup module switches the memory power source from the RAID
controller to the battery pack attached to the iBBU unit. As long as the voltage level stays below the predefined value, the
MegaRAID iBBU unit provides power for memory. If the voltage level returns to an acceptable level, the iBBU unit
switches the power source back to the RAID controller, and all pending writes to storage devices are completed with
no data loss.
1.1.3 Intelligent Transportable Battery Backup Units
An intelligent transportable BBU unit, which combines a battery and memory, can be used to move cached data from
a failed controller to a replacement controller. This action could be necessary if, for example, the controller fails after
an unexpected power failure. After you install the iTBBU unit on a new RAID controller of the same type as the failed

controller, it flushes the unwritten data preserved in the cache to the drive through the new controller. For more
information, see Section 3.4, Transferring Cached Data from a Failed Controller, on page 130.
1.1.4 RAID Cache Module
The RAID Cache Module 01 (RCM01) is a memory module used with the LSIiBBU09 unit. The RCM01 module, which is
attached to a RAID controller, connects by cable to a LSIiBBU09 unit. The LSIiBBU09 unit is then installed remotely on
the system chassis.
1.1.5 CacheVault Modules
The remote CVPM module provides the power to offload cached data from the DRAM to the nonvolatile flash memory
on the CVFM module if a power failure or outage occurs. The DRAM contents are then restored to the CVFM module
the next time the RAID controller is powered. Cached data can then be written to the storage devices.
CacheVault flash technology virtually eliminates the hardware 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.

CacheVault Flash Modules and CacheVault Power Modules
1.4 CacheVault Flash Modules and CacheVault Power Modules
The CVFM modules use a mezzanine-style board-to-board connector to provide capacitor charge maintenance,
capacitor health monitoring functions, USB/ONFI interface, and optionally SDRAM between a low-profile PCIe® 3.0
controller and the CVFM module. The CVFM modules are attached directly to RAID controllers and protect cached
data in different ways.
The CVFM modules connect to a CVPM module, which is a super-capacitor pack that provides power for the backup of
your data in case of power loss. The CVPM module is installed directly on the RAID controller or remotely, depending
on the specific module.
The CVPM module provides sufficient energy for the cache memory contents to be transferred from DRAM to a
nonvolatile flash memory array on the CVFM module.

Chapter 2: Installing the Cache Backup Products
This chapter explains how to install the BBU units that are used on MegaRAID SAS RAID controllers and how to
connect the CacheVault module to backup power units.
CAUTION Electrostatic discharge can damage the BBU units and the RAID
controllers on which they are installed. Always ground yourself, and
use a ground strap before touching the RAID controller or the BBU
unit. Perform all installation work at an ESD-safe workstation that
meets the requirements of Electronic Industries Alliance (EIA) 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 to attach the iBBU unit to the RAID controller, 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 may damage the board, connectors, or screws, and you will void the warranty of the board.
The batteries in the iBBU units must recharge for at least six hours during fast charge under normal
operating conditions.
Chapter 2: Installing the Cache Backup Products
Installing the LSIiBBU01 Unit
NOTE To protect your data, Avago recommends that you set the RAID
controller Write Policy to write-through until the battery unit is
charged. After the battery unit is charged, you can change the Write
Policy to write-back to take advantage of the performance
improvements of data caching.
The maximum operating temperature (ambient) for the battery packs is 40 °C. See Chapter 4, Battery Backup Unit and
CacheVault Specifications, for the technical specifications for the iBBU units.
NOTE The temperature of the battery packs are generally 15 °C to 20 °C
higher than the ambient temperature during fast charge. Therefore, to
complete fast charge cycle, ambient temperature should be less than
40 °C. If the ambient temperature exceeds 40 °C, the fast charge cycle
terminates prematurely, which prevents the battery pack from
reaching a fully charged state.
2.1 Installing the LSIiBBU01 Unit
The two types of LSIiBBU01 units are:
LSI intelligent Battery Backup Unit 01– NiMH (Nickel Metal Hydride)
LSI intelligent Battery Backup Unit 01 – LiON (Lithium Ion)
WAR NIN G The battery used in this device might present a fire or chemical burn
hazard if mistreated. Do not disassemble, heat above 100 °C, or
incinerate. Dispose of used battery correctly. Keep away from children.

The LSIiBBU01 does not mount directly to the MegaRAID controller. Instead, use the supplied 10-in. cable to connect
the LSIiBBU01 unit to a RAID controller, as shown in the example in the following figure. The battery backup unit must
be mounted inside the chassis within 12 in. of the RAID controller.
NOTE Because server and workstation chassis vary from vendor to vendor,
there is no standard mounting option that is compatible with the
various system configurations. Therefore, the LSIiBBU01 battery kit
contains only the battery and the cable, allowing value-added
resellers (VARs) and chassis manufacturers to customize the location
of the remote battery to provide the most flexibility within
various environments.
