Preface

This IBM Redbooks publication provides best practice guidance for planning, installing, and configuring the IBM System Storage TS7600 ProtecTIER family of products. This guide provides the current best practices for using ProtecTIER software version physical general availability (pGA) 3.3 and the revolutionary and patented IBM HyperFactor deduplication engine, along with other data storage efficiency techniques, such as compression and defragmentation.

The System Storage TS7650G ProtecTIER Deduplication Gateway and the System Storage TS7620 ProtecTIER Deduplication Appliance Express are disk-based data storage systems that are configured for three available interfaces: The Virtual Tape Library (VTL) interface is the foundation of ProtecTIER and emulates

traditional automated tape libraries. The OpenStorage (OST) application programming interface (API) can be integrated with

Symantec NetBackup to provide backup-to-disk without having to emulate traditional tape libraries.

The File System Interface (FSI) supports Common Internet File System (CIFS) and Network File System (NFS) as backup targets.

For your existing ProtecTIER solution, this guide provides preferred practices and suggestions to boost the performance and the effectiveness of the data deduplication with regards to your application platforms for your VTL, OST, and FSI systems.

When you build a ProtecTIER data deduplication environment, this guide helps your IT architects and solution designers plan for the best options and scenarios for data deduplication for their environments. This guide helps you optimize your deduplication ratio, and at the same time reduce the hardware, power and cooling, and management costs.

This guide provides expertise that was gained from the IBM ProtecTIER Field Technical Sales Support (FTSS) group, development, and quality assurance (QA) teams. .

Chapter 1. IBM ProtecTIER basics

This chapter describes the general concepts of IBM ProtecTIER as related to its fundamental operation, including a list of terms and definitions that are used in this book and in the ProtecTIER environment. In addition to the ProtecTIER Management Interface, a brief overview is also provided about the existing models, and the benefits of the ProtecTIER command-line interface (ptcli).In addition, this chapter provides readers with an introduction to the ProtecTIER engine for deduplication, which is IBM HyperFactor. This chapter also describes the Remote Support and Call Home capabilities, and the Simple Network Management Protocol (SNMP) functionality.

The following topics are discussed: Terminology used in the ProtecTIER environment ProtecTIER fundamental concepts ProtecTIER models for open systems Remote support and Call Home SNMP ProtecTIER command-line interface (CLI) overview

1 Copyright IBM Corp. 2012, 2014. All rights reserved. 3

1.1 TerminologyThe following terms and definitions are used in this publication, and are common for all products from the ProtecTIER family:ProtecTIER When used alone, this expression points to the IBM patented

deduplication solution based on HyperFactor. Depending on the context, it can mean the family of products, a specific device, or just the deduplication engine.

TS7600 When used alone, this term signifies the IBM System Storage family of virtualization solutions that operate on the ProtecTIER platform, including the ProtecTIER appliances and gateways.

Factoring ratio The factoring ratio is the ratio of nominal capacity to physical capacity in the ProtecTIER repository. For example, if you have 100 terabytes (TB) of user data (nominal capacity) and it is stored on 10 TB of physical capacity, your factoring ratio is 10:1.

HyperFactor The patented IBM algorithm that eliminates data duplicates from the incoming backup data streams. The factoring ratios are the result of HyperFactor processing and compression.

VTL Virtual Tape Library. The ProtecTIER VTL service emulates traditional tape libraries. By emulating tape libraries, you can use ProtecTIER VTL to migrate to disk backup without having to replace your entire backup environment.

Shelf A container of VTL cartridges in a ProtecTIER repository. This container is analogous to a shelf or a rack where physical tapes are kept outside of the automated tape library (ATL) in cartridge slots. This container is only applicable with the VTL configuration option, and is not available in OST or FSI configuration options.

OST OpenStorage. This configuration option enables ProtecTIER to be integrated with Symantec NetBackup to provide a backup-to-disk capability without using a VTL emulation. Using a plug-in that is installed on an OST-enabled media server, you can use ProtecTIER to implement a communication protocol that supports data transfer and control between the backup server and the ProtecTIER server. Therefore, you use ProtecTIER to implement a storage server emulation.

FSI File System Interface. This configuration option enables ProtecTIER to present disk repository storage as a virtualized hierarchy of file systems.

FSI-CIFS FSI Common Internet File System. ProtecTIER emulates Windows file system behavior and presents a virtualized hierarchy of file systems, directories, and files to Windows CIFS clients. When configured for FSI-CIFS, ProtecTIER emulates a network-attached storage (NAS) backup target capable of using both HyperFactor and ProtecTIER native replication bandwidth reduction techniques for storing and replicating deduplicated data.

FSI-NFS FSI Network File System. ProtecTIER emulates UNIX file system behavior and presents a virtualized hierarchy of file systems, directories, and files to UNIX-based clients using the NFS protocol. 4 IBM ProtecTIER Implementation and Best Practices Guide

When configured for FSI-NFS, ProtecTIER emulates an NAS backup target that can use both HyperFactor and ProtecTIER native replication bandwidth reduction techniques for storing and replicating deduplicated data.

System console The system console that is used with the System Storage TS7650 ProtecTIER Appliance products and System Storage TS7650G ProtecTIER Deduplication Gateway (TS7650G, or ProtecTIER Gateway) is the IBM System Storage TS3000 System Console (TSSC). The System Storage TS7620 ProtecTIER small and medium business (SMB) appliance has included system console functions, and therefore does not require a TSSC.

Metadata Metadata is the information used to track the user data sent from the backup servers, including where it is stored on the disk.

User data User data consists of the backup files and data sets that are stored in the ProtecTIER system. It is the data that the backup applications are storing on disk.

Repository The repository is the physical disk that holds the ProtecTIER factored data. There are two types of file systems that make up the ProtecTIER Repository:

MetadataUser data

Front-end The connection from ProtecTIER to the backup server.Back-end The connection from ProtecTIER to the attached disk storage

subsystem that acts as a repository.Node and server A single ProtecTIER system. It can be either a TS7650G or System

Storage TS7620 ProtecTIER Appliance Express (TS7620) or one of the previous models, and is represented as a node from the ProtecTIER Manager software. Stand-alone node or dual-node cluster configurations are available. This book uses the terms node and server interchangeably.

1.1.3 ProtecTIER replication terminology Replication enables you to set rules (depending on your required replication needs) for replicating data objects across ProtecTIER repositories. The ProtecTIER repositories can be different in size and physical layout. Because ProtecTIER deduplicates data before storing it, only the changes are transferred to the remote site. These rules for replicating data objects are defined in replication policies on each ProtecTIER system.

Restriction: Effective December 3, 2010, IBM withdrew the 3958 DD3 from marketing. For more information, see the IBM United States Withdrawal Announcement WG10-0109.

Restriction: Effective March 28, 2009, IBM withdrew the 3958 DD1 from marketing. For more information, see the IBM United States Withdrawal Announcement WG09-0016.

Important: The ProtecTIER replication policies are only available on VTL and FSI environments. For details about how to configure the replication rules on OST environments, see section 6.4, NetBackup Storage Lifecycle Policies on page 107.Chapter 1. IBM ProtecTIER basics 7

The replication function enables System Storage TS7600 deployment to be distributed across sites. Each site has a stand-alone or clustered ProtecTIER environment. Each ProtecTIER environment has at least one ProtecTIER server. ProtecTIER servers come with two dedicated replica
