This section provides a list of terms you can use to familiarize yourself with the Avamar family of hardware. Some of these terms, since they refer to multi-node Avamar systems, are not used anywhere else in this guide. Nodes The primary building block in any Avamar system is a node. Each node is a self- contained, rack-mountable, network-addressable server that runs Avamar software on the Linux operating system. All Avamar nodes are Domain Name System (DNS) clients. Note The term "server" in the previous definition is used in the typical industry context (that is, a computer that provides services to other computers or devices). However, for the remainder of this guide, unless otherwise specified, the term "server" is used to refer to a single node or multi-node Avamar system. The term "node" is used to refer to the individual computer/storage platforms that make up an Avamar server. All nodes run the Linux operating system and use RAID data protection. Nodes have 2, 6, 8, or 12 hard drives, depending on node type and storage capacity. The primary differences between node types are: l The amount of internal data storage (if any) l How internal data storage is configured and allocated (that is, RAID level, number of logical units [LUNs] and so forth) l The Avamar application software that is installed on each node type Utility node In scalable multi-node Avamar servers, a single utility node provides essential internal services for the server (for example, administrator server, replication, external authentication, network time protocol [NTP], and Web access). Because utility nodes are dedicated to running these essential services, they cannot be used to store backups. Storage nodes The remaining nodes in scalable multi-node Avamar servers are storage nodes, which store the actual backups. There are three storage node models, the primary difference being the amount of usable storage available: the M600, M1200, and M2400. They are also offered as single node Avamar servers. Single-node servers A single-node Avamar server, whose installation is described in this guide, combines all the features and functions of utility and storage nodes in a single node. In addition to the three storage nodes that were mentioned previously, EMC offers another model for single-node server usage: the Avamar Business Edition (S2400). Extended retention media access node The media access node exports backup data from an Avamar server to a tape library (physical or virtual) for long-term retention purposes. It has a 10GbE port and an HBA port General Information 10 EMC Avamar Data Store Gen4S Customer Installation Guide

not part of an ADS server (not connected to the Avamar multi-node system’s internal network). For installation instructions, refer to the EMC Avamar Extended Retention Media Access Node Hardware Installation Guide. NDMP accelerator node An Avamar NDMP accelerator (accelerator node) is a dedicated single-node Avamar client that, when used as part of an Avamar system, provides a complete backup and recovery solution for supported EMC Isilon, VNX, VNXe, and Celerra systems, and NetApp filers by using Network Data Management Protocol (NDMP) to communicate with these storage devices. It is not part of the ADS server. For installation instructions, refer to the EMC Avamar NDMP Accelerator User Guide. Node resource database (probe.xml) An XML file that stores the types and IP addresses of Avamar server nodes. In addition, probe.xml stores the types and IP addresses of optional nodes, and supports both Network Address Translation (NAT) and multiple network interfaces. Avamar Downloader Service A Windows-based file distribution system that delivers software installation packages to target Avamar systems. Avamar Downloader Service provides more information. Local downloader service A component integrated into the Avamar Installation Manager. The local downloader service (LDLS) allows administrators to check the EMC repository for updated software packages by using the Avamar Installation Manager web interface. The LDLS supports environments where local Windows hosts are unavailable, removing the requirement to copy files directly to the local repository. Avamar FTP site An EMC FTP site that provides anonymous access to Avamar hotfixes and operating system (OS) patches. The FTP site is ftp://ftp.avamar.com. Typically, access to this site is for EMC personnel (there may be exceptions). The contents of the FTP site are not browsable. Avamar Installation Manager A web interface that manages installation, upgrade, and maintenance packages. Avamar Installation Manager on page 15 provides more information. Avamar login manager A process that provides access to an external authentication database, which enables the Avamar system to use existing username and password information for Avamar authentication. Without the login manager, Avamar can only use its internal authentication mechanism. An Avamar server installation or upgrade installs the login manager, and then starts it. The login manager uses the domains configuration file to identify the supported domains. General Information NDMP accelerator node 11

available from the EMC repository. Packages comprise three types: l Client - A release of Avamar file system or application backup software. l Server - A new release of Avamar server software, a service pack, or a patch for the operating system, management console, or Avamar software. l Workflow - A package that runs operations such as replacing a node or changing the session security configuration. Package files use the extension .avp. Bonded network interfaces Bonded network interfaces are used in high-availability (HA) configurations that try to eliminate node ports and switches as single points of failure. Two separate customer network switches are required, one connected to each of two physical interfaces of an ADS node. Outgoing replication and management networks can be configured for bonding through the additional ports on the single-node server. High-availability network HA configuration provides for continued operation in the event of a single point of failure between network components. The primary objective is to provide multiple paths to the customer network so that the system can recover from an individual device or link failure. To do this, HA configuration employs bonded network interfaces that connect to two customer network switches. Each switch is connected to one of two physical interfaces of an ADS node. ConnectEMC A Linux-based program that transfers event data from an Avamar server to EMC Technical Support. Installation of the Avamar software automatically initializes ConnectEMC by passing values from the workflow to the ConnectEMC configuration files. The server software installation requires you to set the ConnectEMC attributes listed in the following table: Table 3 ConnectEMC attributes Attribute Example setting Site name ABC Company, Site ID: 123456 Address: 123 Main Street, Anytown, CA 92618 US Email server mail.example.com Email sender address [email protected] You can set other ConnectEMC attributes after the installation by using Avamar Administrator. Additional information about ConnectEMC is available from the following resources: l EMC Avamar Administration Guide l ConnectEMC for Linux 3.0 Reference Guide General Information 12 EMC Avamar Data Store Gen4S Customer Installation Guide

information to EMC Technical Support once daily, and critical alerts in near-real time on an as-needed basis. Email home uses the same email server that you configure for ConnectEMC. EMC repository A repository that contains server installation packages, client installation packages, and manifest files. The EMC repository currently spans two locations: ftp://ftp.avamar.com and EMC Subscribenet: l High urgency packages such as hot fixes and OS patches are available from ftp:// ftp.avamar.com. l Low urgency packages that have security and entitlement considerations are available from EMC Subscribenet. The actual source location of a package is transparent to the user. The repository is located on the EMC network. Each EMC customer has its own download center that contains files available to it. These files are maintained by the EMC Subscribenet team. Outgoing communication from the Avamar Downloader Service and LDLS to the EMC repository is encrypted with SSL over an HTTP connection. Local repository The /data01/avamar/repo/packages directory on the utility node or single-node server. The directory contains the most current manifest file from the EMC repository, installation packages, and workflow packages. The Avamar Downloader Service and LDLS push packages from the EMC repository to the local repository. If a customer site does not allow Internet access, you can manually copy packages into the local repository. Manifest file An XML file listing all packages currently available for download from the EMC repository. When the EMC Subscribenet team adds a package to the EMC repository, it then adds an entry to the manifest file that describes the package. When the EMC Subscribenet team removes the package from the repository, it then removes the entry for the package from the manifest file. The Avamar Downloader Service automatically downloads the manifest file from the EMC repository once a day and determines if new download packages are available. The Avamar Downloader Service sends the new manifest file to the local repository for each Avamar system. The LDLS manages changes to the manifest file in a similar way to the Avamar Downloader Service. However, the LDLS downloads the manifest file directly to each Avamar system without the requirement for an intermediate host. Information for customers The following is a collection of information about Avamar and the ADS that can guide you when installing and using this product. The EMC Online Support site is a great resource for information and links: https:// support.emc.com/products/ General Information Email home 13

Obtaining an Avamar license key file requires an account for the EMC Software Licensing Central (SLC) on the EMC Online Support site. EMC Technical Support is responsible for obtaining a license key file for your system. For information about cross-version and cross-equipment compatibility, refer to the EMC Avamar Compatibility and Interoperability Matrix on the EMC Online Support site. For numerous best-practice tips about installing, configuring, upgrading, and using Avamar, refer to the EMC Avamar Operational Best Practices Guide on the EMC Online Support site. Numerous technical notes provide supplemental information about rare, unique, or version-specific installation, implementation, and configuration scenarios. Find technical notes by title on the EMC Online Support site. For instance, one technical note, Avamar Client Downloads and Client Manager Installer Upgrades Technical Note, describes how to upgrade client downloads and Avamar Client Manager client installers. Note Starting in Avamar 7.2.x, Avamar Enterprise Manager is no longer available. The technical note Avamar Enterprise Manager Transition to Backup and Recovery Manager provides more information. Fundamental Avamar principles When working with Avamar, always consider the following: l The best practice for replication is to move data from an older generation Avamar server to a newer one and not the reverse. This scenario is typically used to replicate data from the old server as a first step before upgrading it to the latest version of Avamar software, after which the data can be replicated back. l All single-node servers must be replicated, except the S2400 (Avamar Business Edition). Avamar 7.x installation features overview EMC personnel install the Avamar software after you complete the preliminary hardware installation and configuration described in this guide. The Avamar Installation Manager automates the software installation process on servers. EMC Technical Support uses this utility during implementation. Avamar 7.x also includes the Avamar Downloader Service, a Microsoft Windows-based application that automates the installation of future patches and other packages to your Avamar system. Starting in Avamar 7.3, the LDLS is also available for direct download of packages. How long will the Avamar software installation take? Completing the Avamar server software installation takes about two hours, plus the amount of time it takes to upload the Avamar software installation packages to the server. General Information 14 EMC Avamar Data Store Gen4S Customer Installation Guide

the method used. Installing and configuring the Avamar Downloader Service and LDLS are considered post-installation tasks because they are not required to perform Avamar software installation. Avamar Installation Manager During installation, the Avamar Installation Manager user interface is installed on the utility node or single-node server. The Avamar Installation Manager user interface enables EMC personnel to: l Install or upgrade the Avamar software l Install OS, Avamar software, or other hotfix patches after initial Avamar software installation Avamar Installation Manager controls the following: l The EMC repository manifest file l Downloading of packages from the Avamar Downloader Service and LDLS l Monitoring the local repository for any software packages manually added to the server l Dependency and version checks of the downloaded packages l Management of the temporary directory that is used to extract the packages l Deletion of software packages after a successful installation or upgrade Process flow The following diagram shows how the Avamar Downloader Service, LDLS, and Avamar Installation Manager work together with other components to automatically provide installation, upgrade, and hot fix packages. Figure 1 Process Flow for Packages Process flow tasks: General Information Avamar Installation Manager 15

manifest files. This check is done automatically every 24 hours. l The Avamar Downloader Service downloads the manifest from the EMC repository and pushes it to the Avamar Installation Manager, or l The LDLS downloads the manifest from the EMC repository directly to the Avamar Installation Manager. Note During the first communication handshake between the Avamar Downloader Service and Avamar Installation Manager, the Avamar Downloader Service passes information such as its version, its host and IP address, and so forth, to the Avamar Installation Manager. 2. The Avamar Installation Manager processes the manifest file and notifies the user of new packages. 3. The user requests the package by clicking the Download button in the Avamar Installation Manager. l The Avamar Downloader Service then downloads the package and pushes it to the Avamar Installation Manager, or l The Avamar Installation Manager downloads the package directly using the LDLS. 4. The user installs the package by clicking the Install button in the Avamar Installation Manager. Log files The Avamar Installation Manager provides log file information through the web interface. The log information can be exported to a file (.xls or .pdf). The Avamar Installation Manager also provides the Download all system logs icon , which enables you to download all system log files for troubleshooting issues, for example. You must log in to the EMC Customer Support account to use the Download all system logs icon. In-flight encryption A new installation of Avamar sets in-flight encryption to High as the default setting. An upgrade does not change the current in-flight encryption setting. The EMC Avamar Administration Guide provides more information about in-flight encryption. Avamar Downloader Service The Avamar Downloader Service is a file distribution system that delivers software installation packages to target Avamar systems. The distribution process uses minimal bandwidth by downloading only files that you request through the Avamar Installation Manager. The Avamar Downloader Service uses a local file cache to ensure that a file is fetched only once from the EMC repository, no matter how many times an Avamar system requests the file. You can remove old files from the local repository to free disk space. General Information 16 EMC Avamar Data Store Gen4S Customer Installation Guide

The Avamar Downloader Service validates each package that it downloads to ensure that the package has been correctly signed and transmitted. The Avamar Downloader Service accepts incoming requests only from Avamar systems that are on a known systems list. The Avamar Downloader Service encrypts outgoing communication to the EMC repository by using SSL (Secure Socket Layers) over an HTTP connection. Note If the site prohibits access to the Internet, you can manually copy packages to the / data01/avamar/repo directory, and then move them to the /packages directory on the single-node server instead of using the Avamar Downloader Service. Avamar Downloader Service components This section describes the components of the Avamar Downloader Service. Table 4 Avamar Downloader Service components Component Description Avamar Downloader Service Windows service Monitors the EMC repository. When a package is available for the Avamar system, the Avamar Downloader Service service automatically downloads the package and pushes it to the local repository on the Avamar utility node or single-node server.

configuration is required, this chapter describes procedures that must be performed by EMC personnel before Avamar software installation can be done. Included in this chapter are: l General overview of ADS networking principles related to single-node servers l Descriptions of the different network configurations supported by single-node servers l An overview of the optional dpnnetutil advanced configuration utility l Descriptions of replication schemes supported by single-node servers Unlike multi-node servers, the Avamar single-node server has no internal network functionality. The eth1 port (NIC2) is not dedicated to Avamar-specific traffic. Customers typically provide network switching and connections to match their infrastructure for backups, replication, and node management. For the ADS external network, default settings are: l The server is connected directly to customer network switches through NIC1 (eth0) and NIC3 (eth2) ports (bonded as bond0) by default for backing up customer data. l NIC1 is the primary, NIC3 is the secondary (failover). l If RMM4 functionality is used and set to shared, the default shared port is NIC1 (eth0). The preceding default settings can be changed through the dpnnetutil utility described in Advanced network configuration – dpnnetutil utility on page 29. Default network configuration is performed during Avamar software installation. Basic networking configuration ADS Gen4S single node servers follow these configuration principles: l All networking ports are bonded in pairs, by default. l For single-node servers, NIC1 (eth0) and NIC3 (eth2) port bonding can be broken to facilitate incoming replication, which is delivered directly to the server, or for server management. If this bond is broken, high availability backup capability is not possible. l The external customer network switch can be shared with other applications. l If the customer network environment is segregated using backup virtual local area networks (VLANs), corresponding VLANs must be configured on the Avamar server. The customer network administrator must provide a list of VLAN IDs to be used by EMC personnel when running the dpnnetutil utility. l For networks that do not require advanced configuration like VLAN and network address translation (NAT) support, the network configuration included in the standard software installation is used. The exception is eth0, which must be configured in advance of software installation. Networking 26 EMC Avamar Data Store Gen4S Customer Installation Guide

of VLANs and separately support the use of NAT. However, Avamar does not support the use of NAT on VLANs. l If all backup, replication, and management interfaces are used, ensure that they are configured for different subnets. l All network ports autonegotiate to 1 Gb Ethernet (full duplex) on the external customer network. l Connections to the customer network are standard leaf connections directly with the single-node server. See the following sections for further clarification of possible ADS networking configurations. Supported network configurations The following sections describe networking scenarios supported by ADS Gen4S servers. l Single uplink to an external customer network l Dual uplink to an external customer network l Dual uplink plus options to an external customer network Single-node servers Single uplink to external customer network The following figure illustrates a single uplink from the server to the customer network switch. Figure 4 Single Uplink Dual uplink to external customer network For high-availability configurations, the following figure illustrates dual uplinks from the server to the customer network. Networking Supported network configurations 27

The high-availability external network provides an Avamar server that continues operating through any single network component failure, including: l Any ADS network interface on the external network l Any single uplink cable from the ADS to the customer network l Any port on the customer network used in the uplink l An entire customer switch used in the uplink l Connectivity between customer switches used in the uplink Dual uplink plus options to external customer network For high-availability configurations plus replication and management traffic options, the following figure illustrates: l Dual uplinks from the server to the customer network for high-availability backups, and l Single or dual connections to the customer network for outgoing replication or administration traffic. Networking 28 EMC Avamar Data Store Gen4S Customer Installation Guide

This high-availability external network provides an Avamar server that continues operating through any single failure in a default or optional network component, including: l Any ADS network interface on the external network l Any single uplink cable from the ADS to the customer network l Any port on the customer network used in the uplink l An entire customer switch used in the uplink l Connectivity between customer switches used in the uplink Advanced network configuration – dpnnetutil utility For ordinary implementations, the normal software installation process provides all functionality that is required to configure networking on ADS systems. For more advanced configurations, the interactive dpnnetutil utility must be run before software installation. Advanced configuration scenarios include: l Support for VLAN interfaces to backup networks l Setting custom hostnames l Configuring Network Address Translation (NAT) Note Only EMC personnel can run the dpnnetutil utility. If the customer site requires advanced network configuration, alert the EMC Account Team that the implementation specialist must run dpnnetutil before installing the Avamar software. While dpnnetutil is running, the customer may be asked to check certain hardware-related connectivity errors that the utility might report. Networking Advanced network configuration – dpnnetutil utility 29

Running dpnnetutil provides the following features: Single-node Gen4S systems For single-node systems, the feature set includes: l Detection of cabling and connectivity errors during configuration, including: n No link detected on a network interface n Link speed below 1GB n Auto negotiation n Full duplex When an error is detected, a dialog box is displayed that describes the error and the network interfaces affected. l Determination of the cabling schema based on the number of physical network interfaces and link presence. l Configuration of the backup, replication, and management networks, including: n Requesting IP addresses and netmask for replication and management networks n Allowing edit and confirmation later Note Remember, if all backup, replication, and management interfaces are configured for use on the single node server, they must be configured for different subnets. l Configuration of backup VLAN interfaces, including: n Requesting a list of VLAN IDs available on the customer network switch n Requesting corresponding parameters for each VLAN ID (IP, netmask) The customer network administrator must provide a list of correct VLAN IDs (typically in the range 1 to 4094). The site networking topology must be such that all clients are able to resolve the Avamar server by the same hostname from different VLANs. Otherwise, backup failures may occur. The dpnnetutil utility populates probe.xml with information obtained during the configuration procedure. Replication The following sections describe the types of replication architectures supported by ADS systems. For complete instructions on setting up and performing replication, including terms and concepts, capabilities and limitations, and best practices, see the EMC Avamar Administration Guide. Single-node servers The networking architecture of ADS Gen4S and the Avamar software provide two types of replication: Basic and Dedicated. They are described in the following sections. Basic replication The source and target systems each have a single network for traffic of all purposes. Replication is in and out on this single network between the source and target pair. The Networking 30 EMC Avamar Data Store Gen4S Customer Installation Guide

image shows a multi-node server as the target. Figure 7 Basic Replication Network To configure basic replication, the Avamar software must be installed. The EMC Avamar Administration Guide provides more information about configuring basic replication. Dedicated replication A system that is configured for dedicated replication has dedicated networks on both source and target systems. On the source system, dedicated backup, replication, and management ports can be configured. The following image shows a multi-node server as the target. Figure 8 Dedicated Replication Network To configure dedicated replication, the Avamar software must be installed. An EMC implementation specialist must manually perform additional steps.
