Cache Backup Products for MegaRAID® SAS+SATA RAID Controllers User Guide Chapter 1: Introduction
| Overview
Chapter 1
This guide documents the LSI™ family of MegaRAID® intelligent battery backup units
(iBBUs) and transportable memory modules (TMMs) for use with its high-performance
MegaRAID SAS+SATA RAID controllers.
1.1 Overview The battery backup units and the transportable 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.
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. An onboard iBBU unit or TMM module on a
MegaRAID controller eliminates this risk.
1.1.2 Intelligent Battery Backup
Units
The MegaRAID iBBUs 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 Transportable Memory
Modules
The TMMs are attached directly to the RAID controllers that use them and they provide
cache backup. The memory cache backup method uses an onboard FPGA to offload
the SDRAM contents to on-board flash memory in the case of a failure condition.
Depending on the RAID controller, power for the cache offload is provided by either a
remote iBBU unit or a CAP01 unit, which is the CacheVault (CV) super-capacitor pack.
The iBBU unit and the CAP01 unit are installed on remote mounting boards and
connected by cable to the TMM module.
1.2 Types of Battery Backup
Units
LSI supports intelligent BBUs and transportable intelligent BBUs for MegaRAID RAID
controllers.
Introduction

| MegaRAID Battery Backup Units Matrix
An intelligent BBU 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.
A transportable intelligent BBU can be used to move a RAID controller's cached data to a
replacement controller if that data has not been written to a drive. This could be
necessary if, for example, the controller fails after an unexpected power failure. After
you install the transportable iBBU on the new RAID 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.
1.3 MegaRAID Battery

This chapter explains how to install the BBUs that are used on MegaRAID SAS RAID
controllers and connect the TMMs to backup power units. Click on a link below to view
instructions for a specific product:
Section 2.1, Installing the LSIiBBU01 Unit
Section 2.2, Installing the LSIiBBU05 Unit
Section 2.3, Installing the LSIiBBU06 Unit
Section 2.4, Installing the LSIiBBU07 Unit
Section 2.5, Installing the LSIiBBU08 Unit
Section 2.6, Installing the LSIiBBU09 Unit
Section 2.7, Installing the LSIiTBBU03 Unit
Section 2.8, Connecting the TMM01 Module on a SAS 9260 RAID Controller to a
CAP01 Super-Capacitor Pack
Section 2.9, Connecting the TMM02 Module on a SAS RAID Controller to an
LSIiBBU08 Unit or an LSIiBBU09 Unit
CAUTION: Electrostatic discharge can damage the BBUs and the RAID controllers on
which they are installed. Always ground yourself, and/or use a ground strap before
touching the RAID controller or the BBU. 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 IPC-A-610.
If screws are required to attach the iBBU 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 iBBUs must recharge for at least six hours during fast charge under
normal operating conditions. To protect your data, LSI™ recommends that you set the
RAID controller Write Policy to write-through until the battery unit is fully charged.
When 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 for the technical specifications for the iBBUs.

Cache Backup Products for MegaRAID® SAS+SATA RAID Controllers User GuideChapter 2: Installing the Cache Backup Products
| Installing the LSIiBBU01 Unit
NOTE: The temperature of the battery packs are generally 15–20 degrees 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 will terminate prematurely, thus preventing 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)
