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.

1.4.1 Models of the CacheVault Flash Modules

Avago offers four models of the CacheVault Flash Modules:

 The CVFM01 product is a FPGA cache off-load module that is attached to a MegaRAID RAID controller and

connected by cable to a CVPM01 module that is installed on a remote mount board.

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.

CAUTION Damage to the battery backup unit will occur when power is applied

to the system if the cable assembly connectors are installed backwards in either the J1 connector on the board-to-board cable adapter card or on the J2 BBU connector. The cable connectors are polarized, and the keying features of the connector are designed to allow the connectors to be attached in only one orientation. The cable end inserts into the connector with only minimal resistance.

Even with the keying features, if excessive force is used, it is possible to install these connectors incorrectly. To assist in correct alignment, the small triangles that designate pin 1 on each connector are marked in black. Make sure these triangles line up as shown in the illustrations. The wire that connects to pin 1 of each end of the cable assembly is yellow on most Avago cables.

2.7 Installing the LSIiTBBU03 Unit

The LSIiTBBU03 intelligent transportable BBU unit, which is used with the MegaRAID SAS 8888ELP RAID controller, connects directly to the RAID controller in the MiniDIMM socket. The LSIiTBBU03 intelligent transportable BBU unit is compliant with the Smart Battery Data Specification, which relieves the host system from the responsibility of communicating battery information and charging the battery. Battery charging and recharging take place automatically.

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.

To connect the LSIiTBBU03 unit directly to the RAID controller, perform the following tasks in order:

1. Remove the RAID controller from the host computer. See Section 2.7.1, Removing the RAID Controller from the

Host Computer, on page 86.
