5 1 Introduction This guide explains how to set up OnCommand Balance in your data center. It also describes the minimum requirements for discovering and collecting data from each data center resource you want to monitor. 5

6 Balance overview Functionality Balance is a software solution that exists on the Balance virtual appliance (VA). Balance provides a complete, end-to-end view of your data center, from the physical storage that holds your data to the applications that process and control that data. It monitors your data center to identify and alert you to performance bottlenecks, such as latency, storage contention, and over-utilization, before they occur, so that you can take corrective action. It also allows you to plan data center configurations, such as adding or removing servers or storage systems, to determine the potential impact to overall data center performance. For a more detailed product overview, see the OnCommand Balance User Guide. The main Balance functionality is discovery, data collection, analysis, and data reporting. Balance provides access to configure Balance and begin discovery using the Hypertext Transfer Protocol (HTTP) or Secure Hypertext Transfer Protocol (HTTPS). Discovery Balance uses the IP network to discover data center resources. To add resources to Balance, you can import a seed list or manually add each resource you want to discover and monitor. During discovery, Balance collects information about the resource, such as the resource configuration and its relationship to other data center resources. Balance uses the information to build a topology that maps the path between each monitored application, server, and the connected storage systems. Data collection After the resources have been discovered, Balance begins to collect their operational data into its database. The data includes information such as disk IOPS, disk latency, and server CPU and memory usage. If IOPS, for example, jump during a discrete time period on a particular LUN, Balance captures this information. Within a few hours of discovery, Balance can begin performance analysis against the collected data. As Balance collects more data the analysis beings to provide more accurate and meaningful performance statistics. Analysis The word analysis, as used by NetApp, refers to actions that Balance performs when examining data center statistics for performance issues. Balance collects quantitative data such as IOPS, latency, and memory paging, then uses the data to determine whether there are any problems with operations in the data center. If Balance identifies an existing or potential problem, it provides recommendations that you can use to resolve the problem. 6

7 Data reporting Balance provides several reports that display configuration information for each monitored resource, including with statistics that show the current and trending performance. Balance analyzes these trends and provides recommendations for resolving potential problems it identifies. You can analyze the reported trends and make changes based on those trends at any time.

9 2 Setting up Balance This chapter explains how to install Balance in your data center. See the following sections: Installation overview on page 10 Virtual appliance requirements on page 12 Deploying the virtual appliance on page 13 Configuring the virtual appliance on page 14 Setting up the Balance Proxy on page 15 Client system requirements on page 18 9

10 Installation overview New installation Balance is distributed as a virtual appliance (VA) in the OVA format. You can download the OVA from the NetApp Support Web site at: To install Balance, you deploy the OVA to an ESX Server from your vsphere Client. During deployment, the OVA converts to a virtual machine (VM). You then log in to Balance through a Web browser to configure the VA as a new installation or to upgrade an existing 3.6 VA. Setting up a new Balance VA involves the following tasks: 1. Ensure that the ESX Server that will host the VA meets the minimum requirements. See Virtual appliance requirements on page Deploy the VA to an ESX Server. See Deploying the virtual appliance on page In a Web browser, access Balance and select the option to configure it as a new server. See Configuring the virtual appliance on page Install and configure the Balance Proxy. Balance requires the proxy to discover Windows servers and some storage arrays. Depending on the storage array type, you may need to install and configure multiprovider software in addition to the proxy. See Setting up the Balance Proxy on page Add data center resources you want to discover and monitor. For the minimum requirements for discovering each resource, see Chapter 3, Configuring resources for data collection. 10

11 Upgrade Upgrading an existing Balance 3.6 VA involves deploying the VA and then migrating the historical data and configuration settings from the 3.6 VA to the VA. Important! Before proceeding, we strongly recommend that you clone or back up the VA. Upgrading involves the following tasks: 1. Ensure that the ESX Server that will host the VA meets the minimum requirements. See Virtual appliance requirements on page Deploy the VA to an ESX Server. See Deploying the virtual appliance on page If you need to configure an additional network adapter on the VA, to separate network traffic, for example, you must do so before you proceed with the upgrade. Important! Adding a network adapter involves restarting Balance on the VA. During the upgrade, Balance must remain powered-on until the data migration from the 3.6 VA has completed, or you risk data loss. See Adding network adapters to Balance on page In a Web browser, log in to Balance to configure the VA and select the option to migrate historical data and configuration settings from a 3.6 VA. You specify the name and admin credentials for the 3.6 VA from which to migrate data to the VA. Note: If you specify credentials for an Active Directory account, the upgrade might fail to access the 3.6 VA. The configuration settings migrate first, at which time the 3.6 VA is temporarily unavailable, and then the VA begins data collection. The historical data migrates over time. You can still log in to the 3.6 VA, but it will no longer collect and display new data. See Configuring the virtual appliance on page On the Balance Dashboard, use the instructions in the data migration section, on the right, to upgrade the existing Balance Proxies to be compatible with Balance Note: To ensure that the proxies meet the minimum host and resources requirements, review the minimum requirements in Setting up the Balance Proxy on page 15. 3/6/1211

12 Virtual appliance requirements The ESX Server on which you deploy the VA must meet minimum resource requirements. The VA resource requirements increase based on the number of servers you plan to monitor. vsphere requirements For deploying the VA, you can use VMware vsphere Client version 4.0, 4.1, or 5.0. ESX Server requirements Table 4 on page 12 lists the minimum requirements for the VMware ESX Server that will host the VA. Table 4. ESX Server requirements Resource Minimum Requirements ESX Server Versions 4.0, 4.1, or 5.0. Hardware and software must be 64-bit. Network Virtual CPUs Virtual Memory Disks Storage 1 Gigabit Ethernet connection for fastest installation (optional). DHCP recommended for the VA (default) GHz 3.6 GB At least 5 disk spindles in RAID DP or other RAID array. Datastore requires at least 205 GB of disk capacity, which includes an extra 5 GB for VA memory and additional files (for example, swap). Refer to VA resource recommendations on page 12 for the minimum number of recommended disks. VA resource recommendations Table 5 on page 13 lists the VA resource recommendations based on the number of servers you plan to monitor. Additional virtual CPUs can be added through the vsphere Client. The VA has a minimum memory reservation of 4000MB (the default). If this amount is not available on the ESX Server, the VA might not power on. You can lower the memory settings of the VA in an environment with 100 monitored servers or less. 12

13 Table 5. VA resource recommendations Monitored Servers vcpus CPU Reservation (MHz) Memory (MB) Memory Reservation (MB) Minimum Disks Network Usage (KBps) or less 2 a a For non-production/demo usage, you can configure Balance with 1 vcpu; this configuration is not otherwise recommended. Deploying the virtual appliance This section explains how to use a VMware vsphere Client to deploy the VA to an ESX Server. The vsphere Client converts the VA to a virtual machine (VM). Important! If you are upgrading from a 3.6 VA, we strongly recommend that you clone or back up the VA before proceeding. To deploy the VA: 1. Download the VA from the NetApp Support Web site at 2. Save the OVA file to a local or network location that is accessible to your vsphere Client. 3. In the vsphere Client, on the File menu, select Deploy OVF Template. 4. Complete the Deploy OVF Template wizard to deploy the VA. Note: For the VM disk format, we recommend selecting Thin Provisioned. Thin provisioning allows the Balance database to efficiently grow to the maximum available capacity, as you add resources to your data center. vsphere 4.0 does not have this option. For information on thin provisioning, see the online help for your vsphere Client. 5. After the VA has successfully deployed to the ESX Server, power on the VA. 6. In vsphere, click the Console tab to monitor the power-on status: VA powers up. Balance starts up. 3/6/1213

14 Balance uses DHCP to assign an IP address to the VA. If DHCP is not detected, you are prompted to specify the network settings for assigning an IP address to the VA. You enter this IP address in a Web browser to access and use the Balance Web client. 7. Proceed to Configuring the virtual appliance on page 14. Configuring the virtual appliance After deploying the VA and powering it on, you can then open a Web browser and use the IP address assigned to the VA to access Balance and begin the configuration. When you first log in, you can select to set up Balance as a new server or migrate configuration settings and historical data from an existing Balance 3.6 VA to the new VA. Note: If you are migrating settings and data from an existing Balance 3.6 VA, ensure that the existing VA is powered on. If you have changed the root password on the existing VA from the default, you will be prompted to enter the root password during the upgrade. To configure the VA: 1. Open a Web browser. Note: For the minimum client system requirements, see Client system requirements on page In the address bar, enter the FQDN/IP address assigned to the VA when it was deployed. 3. Follow the on-screen instructions to configure a new VA or upgrade an existing VA. After you complete the configuration, the login page appears. 4. Enter your login credentials. If upgrading, enter the credentials for the 3.6 VA. Default is the following (all lowercase): User: admin Password: password For new installations, the Welcome page appears. Note: If you choose to migrate settings and data from an existing VA, the data continues to migrate in the background. Balance and the existing source Balance VA both display the migration status, but Balance is more accurate. 5. In Balance, click Help and complete the tasks listed in the topic Getting started with Balance for instructions on configuring Balance and adding data center resources you want to monitor. 14

15 Setting up the Balance Proxy The Balance Proxy is required to discover Windows servers and some storage arrays. Install the proxy on a physical or virtual host. Balance uses the proxy to perform discovery collections on the monitored resources. Figure 1 on page 15 shows which resources, in green, must be discovered through the Balance Proxy and which resources also require a multiprovider, either standalone or in addition to the proxy. Figure 1. Resources Requiring a Proxy or Multiproviders 3/6/1215

16 About multiproviders To discover and collect data from some storage arrays, Balance requires multiprovider software, either standalone or in addition to the Balance Proxy. Depending on the storage array type, the multiprovider must be on either the Balance Proxy server or on a server accessible to Balance. To reach the storage array, Balance can communicate with the appropriate multiprovider directly or communicate with the proxy, which communicates with the multiprovider. During the proxy installation, you can browse to the location of some multiprovider software that is installed on the proxy host, while other multiproviders require more advanced configuration. The following storage systems require multiproviders: EMC CLARiiON on page 31 EMC Symmetrix on page 32 Engenio on page 34 HP EVA on page 34 HP XP on page 35 Proxy host requirements Hitachi Data Systems on page 36 The host on which you install the Balance Proxy must meet the following minimum requirements: Dedicated Windows Server 2003 SP1 or greater. Dedicated Windows Server 2008 R2 with User Account Control (UAC) disabled. Note: Other Windows versions are not supported. Firewall disabled or open port 9443 for proxy communication. See Communication ports on page bit version of Java is required for both 32- and 64-bit systems. See Java Runtime Environment on page 19. At least 20 GB of disk space assigned to the proxy, approximately 10 GB should be available after installation. If antivirus software is installed on the proxy host, script scan functions must be disabled. We recommend excluding the following directory from virus scan: C:\Program Files\netapp 16

17 The proxy should be accessed by a single Balance VA only. Proxy host requirements based on the number of monitored servers Table 6 on page 17 lists the resource limitations for the Windows Server hosting the Balance Proxy. The values are based on the number of servers (physical and virtual) that you plan to monitor. Note: Values apply specifically to Windows Server 2003 hosts. Values for Windows Server 2008 hosts might be higher. Table 6. Proxy host requirements Monitored Servers vcpus CPU Reservation (MHz) Memory Reservation (MB) Minimum Disks Network Usage (KBps) or less There is a Microsoft bug where the lsass.exe process consumes 100% of Java CPU. This causes a slow response logging into the Balance Proxy as well alerts regarding high CPU utilization from the Virtual Center hosting the proxy. This problem was found on Windows 2003 and 2008 standard. However, Windows 2008 r2 is not affected. For information about Windows 2003 lsass.exe, see the Knowledge Base article at AntiVirus script scan capability might also cause high CPU utilization. Disable the script scan on the Balance Proxy. 3/6/1217

18 Installing the Balance Proxy This section explains how to install or upgrade the Balance Proxy. You use a wizard that steps you through installing the proxy and specifying the multiproviders that the proxy requires to communicate with some resources. For a list of resources that require multiproviders, see About multiproviders on page 16. To install or upgrade the proxy: 1. Review the proxy host requirements in Proxy host requirements on page Open a Web browser window and log in to Balance. 3. On the Discovery menu, select Proxies > Add proxy. Note: If upgrading a 3.6 VA, the Dashboard displays instructions for upgrading the existing proxies. 4. Follow the on-screen instructions to install the proxy. The installer file displays and you can choose to open and run the proxyinstall.jnlp file, which starts the proxy installation wizard. 5. Select to open the installer file. 6. Use the wizard to install or upgrade the proxy. On the step for installing multiproviders, the proxy installer displays the default paths where it expects to find multiproviders installed on the proxy host. If any of the paths are incorrect, click Browse to locate the multiprovider and update the path. Important! If you do not install all multiproviders initially, but install them at a later time, you must reinstall the proxy and select the appropriate check boxes for each new multiprovider you added. Client system requirements Web browser This section lists the client system requirements for accessing Balance through a Web browser. To ensure that the Balance interface displays properly, use one of the following browsers: Mozilla Firefox 6.0 or greater. Microsoft Internet Explorer (IE) 7 or greater. IE 8 or 9 recommended. Note: For IE 8, ensure Compatibility Mode (Compatibility View) is disabled. For IE 9, ensure Compatibility Mode is enabled. See the Microsoft IE online help for information on enabling and disabling Compatibility Mode. 18

19 Java Runtime Environment Flash Player Balance requires a minimum of JRE v1.6 with update 24 or greater for optimal graphing capabilities. To display the Data Topology pages in Balance, the client system must have Adobe Flash Player or greater. 3/6/1219

21 3 Configuring resources for data collection Before Balance can discover and collect performance statistics from your data center resources, you must make sure that each resource meets the minimum software requirements. If the resource requires the Balance Proxy, the proxy may require multiprovider software to discover the resource. Balance supports equipment from several vendors. See the following sections to ensure that each of your resources meet the minimum requirements for discovery: VMware vcenter Server and ESX/ESXi Server requirements on page 22 Windows and Hyper-V Server requirements on page 23 Linux/UNIX server requirements on page 25 Storage system requirements on page 29 Virtualization software requirements on page 39 SAN device requirements on page 42 Database requirements on page 43 Communication ports on page 47 21

22 VMware vcenter Server and ESX/ESXi Server requirements vcenter Server VMware ESX/ESXi Server Balance supports VMware vcenter Servers and allows for the discovery of hosts and guests associated with physical ESX servers. You can also add ESX Servers as standalone hosts. Important! The user account for accessing the vcenter Server or ESX/ESXi Server must have a user role at the data center level (top of the tree) with the Browse Datastore privilege. Balance requires this role to collect statistics for VM datastores. Balance supports monitoring of the following versions of vcenter Server: vcenter 5.0 (for ESX 4.0.x and 4.1.x ESX hosts) vcenter 4.0 and 4.1 (for ESX 4.0.x, and 4.1.x ESX hosts) vcenter Server 2.5 (for ESX 3.5.x hosts) Note: Each vcenter Server you add to Balance must have a unique vcenter ID. Balance supports standalone VMware ESX/ESXi Server 4.0 or greater. It can also track VMotion activity. To discover ESX/ESXi Servers, Balance has the following discovery requirements: FQDN/IP address of the server. Username and password for the server. Note: VM guests must have VMTools installed before they can be monitored. ESX/ESXi Servers have the following limitations: ESX hostd process stops and restarts with 'exceed hard limit' memory errors when monitored by multiple Balance systems. A patch from VMWare is required. The patch is available at: d=displaykc&externalid= VMware Tools must be installed and up-to-date on all guests for statistics gathering. See the Hypervisor Tools section of Accessing the AMT on page 49 for more information. 22

23 Balance uses the VMware SDK (Software Development Kit) to communicate with VMware ESX servers (installed by default on most systems). The SDK retrieves data via SOAP requests over HTTP. Note: If you want to configure this host or its cluster for vcenter Server discovery, see VMware vcenter Server and ESX/ESXi Server requirements on page 22. Important! Balance only supports Raw Disk Mappings (RDM) in physical compatibility mode. Windows and Hyper-V Server requirements Windows Server See the following sections for Window and Hyper-V discovery requirements: Windows Server on page 23 Hyper-V Server on page 25 Important! If you are monitoring Windows or Hyper-V servers that have physical mappings to Symmetrix DMX/V-Max (SE only) arrays, you must install the inq.exe in the following path on the Balance Proxy host: c:\program Files\NetApp\bin Note: Balance uses WMI to discover Windows and Hyper-V servers. If the servers are behind a firewall, see Configuring Ports Behind Windows Firewalls on page 47 to ensure that Balance can access the necessary ports. Table 7 on page 24 lists the supported versions of Windows and the configuration requirements for discovering each server as a standalone or physical server. Note: If your Windows server is part of a cluster, see Microsoft cluster multiprovider on page 24. 3/6/1223

24 Table 7. Windows Server requirements Version Windows Server 2008 with SP1 or SP2 Windows Server 2008 R2 Windows Server 2003 with SP2 Software Requirements Have a local user account or domain account with valid username and password that is a member of the administrators group. Have firewall disabled or open port See Communication ports on page 47. Be accessible to the Balance Proxy. You can optionally run the following: FCINFO (Fibre Channel Info Tool) Multipathing software (for example, Powerpath, SecurePath, or MPIO are supported). Have a valid username and password with local administrator permissions on the server or domain administrator permissions. Have firewall disabled or open port See Communication ports on page 47. Be accessible to the Balance Proxy. You can optionally run the following: FCINFO (Fibre Channel Info Tool) Multipathing software (for example, Powerpath, SecurePath, or MPIO are supported). Note: If you are using STORport Miniport drivers, multipathing software is required (for example, Powerpath, SecurePath, or MPIO are supported). Supported drivers include STORport and SCSIport Miniport drivers. Microsoft cluster multiprovider For Microsoft clusters, create a credential for the Windows 2003/2008 servers in your cluster, use an existing Balance Proxy machine, and specify the cluster FQDN or IP address in Balance when adding the Microsoft Cluster multiprovider. Do not configure the individual cluster nodes for discovery. When Balance discovers the Microsoft Cluster multiprovider, all nodes in the cluster will appear in Balance as unmonitored. You will need to manually change each node to monitored. 24

25 Hyper-V Server Table 8 on page 25 lists the supported versions of Windows Hyper-V Server and the software requirements for discovering the server. Note: Balance does not support clustering for Hyper-V. Balance discovers Hyper-V virtual machines and adds Windows guests to the Unmonitored list. Table 8. Hyper-V Server requirements Version Software Requirements Windows Server 2008 R2 Have a local user account or domain account with valid username and password that is a member of the administrators group. Have firewall disabled or open port See Communication ports on page 47. Be accessible to the Balance Proxy. You can optionally run the following: FCINFO (Fibre Channel Info Tool) Multipathing software (for example, Powerpath, SecurePath, or MPIO are supported). Note: STORport Miniport drivers are supported by default. Linux/UNIX server requirements To prepare each Linux/UNIX server for discovery and user authentication, see the following sections: Linux/UNIX discovery requirements on page 25 Configuring password authentication for Linux/UNIX servers on page 28 Configuring RSA authentication for Linux/UNIX servers on page 29 Linux/UNIX discovery requirements Table 9 on page 26 lists the system requirements for discovering physical (standalone) Linux/UNIX servers.

28 Configuring password authentication for Linux/UNIX servers If you are using password authentication with a Linux/UNIX server, add the Balance user to /etc/sudoers using the visudo command. Important! The following entries must be in your sudoers file, which can only be modified by running visudo as root. Visudo can be found in /usr/local/sbin Defaults!env_reset Syntax: username hostname = NOPASSWD: /sbin/lvm,/sbin/scsi_id,/sbin/dmsetup,/sbin/fdisk where: username is the username for accessing the Linux/UNIX server. hostname is the FQDN/IP of the Linux/UNIX server. If you are using one or more of the following tools, add their associated paths to your sudoers file. QLogic Host Bus Adapter Simple Command Line Interface (SCLI): /usr/local/bin/scli Powerpath: /sbin/powermt Veritas Volume Manager: /usr/lib/vxvm/diag.d/vxdmpinq,/usr/sbin/vxdisk Note: When running Veritas Volume Manager 5.1 or greater, replace the use of the vxdmpinq utility, with the vxscsiinq utility. MD devices: /sbin/mdadm The hostname can be ALL to allow a connection from any host. (ALL) after the = is the UID with which you are allowed to sudo. Replace username and hostname with the appropriate values. Note that the default locations are assumed for these utilities. Note: To enable a password prompt, change NOPASSWD to PASSWD in the previous sudo entry. 28

29 Configuring RSA authentication for Linux/UNIX servers If you are using RSA authentication with Linux/UNIX, perform the following steps: 1. Do one of the following to create the RSA keys: For RSA authentication on the Balance VA, use the read-only self monitor credentials. For RSA authentication on Linux/UNIX servers, create an RSA keypair using the ssh-keygen program from the read-only Balance user account. Important! Do not use a third-party key generator, such as PuTTy, to create the RSA keys. 2. In the user directory where the newly created RSA keys are located, copy or rename the id_rsa.pub key to authorized_keys. The private id_rsa key file or the ASCII contents of this file will be used when creating the RSA credential on Balance. Note: If you created the RSA keys on the Balance VA, copy the public key file to all Linux/UNIX hosts that will use RSA authentication. 3. In Balance, create the RSA credentials. 4. On the Add Credentials page, for RSA File, upload the private side of the RSA keypair to Balance and specify the RSA key to use. Note: The private key must be accessible to Balance. Storage system requirements This section lists the requirements for collecting discovery and statistical data from storage systems in your data center. Balance can communicate with some storage systems directly, while others require the Balance Proxy and some require the proxy with multiprovider software. Statistics collection support Balance collects performance statistics for the following storage systems. For storage systems not listed, Balance collects the statistics from the connected servers. NetApp on page 30 EMC CLARiiON on page 31 HP EVA on page 34 Hitachi Data Systems on page 36 IBM SAN Volume Controller (SVC) on page 41 3/6/1229

30 NetApp To discover and collect statistics from NetApp FAS storage systems, Balance has the following requirements: Data OnTap or greater. To discover the storage system, use the administrator (root) account. To use a user account, see Discovering a NetApp storage system with a user account on page 30.

Configuring the proxy for Symmetrix DMX/VMAX arrays For EMC Symmetrix DMX/VMAX (SE only), you can install the proxy out-of-band or in-band of the Symmetrix array: Out-of-band configuration (recommended) involves running the proxy and a copy of Solutions Enabler 6.4 or greater on a dedicated Windows Server host that is not connected to the Symmetrix array. The proxy communicates with the Symmetrix array by communicating through the Solutions Enabler host that is connected to the array. 32

33 In-band configuration involves running both the proxy and Solutions Enabler on the same Windows Server host that is connected to the Symmetrix array. The in-band configuration is not recommended since the proxy service can put additional load on the server and the version of Solutions Enabler must be 6.4 or greater. To configure out-of-band communication: 1. On the Balance Proxy host, locate the following configuration file: C:\Program Files\EMC\SYMAPI\config\netcnfg 2. In a text editor, open the netcnfg file 3. Add the following line, or edit one of the examples, to specify the name and address of the Solutions Enabler host that is connected to the Symmetrix array: SE_Host - TCPIP node001 SE_IP SE_Port - where, SE_Host is the name of the Solutions Enabler host connected to the Symmetrix array. SE_IP is the IP address of the Solutions Enabler host connected to the Symmetrix array. SE_Port is the port on the Solutions Enabler host connected to the Symmetrix array. 4. Add the following Windows System Variables: SYMCLI_CONNECT_TYPE = REMOTE SYMCLI_CONNECT = SE_Host where, SE_Host matches the value for SE_Host in step 3 on page The proxy associates this value with the value in the netcnfg file to locate the Solutions Enabler server connected to the Symmetrix array. 5. Restart the Balance Proxy service. 6. To validate the out-of-band configuration, open a command prompt and type the following: symcfg list The list of Symmetrix arrays appears. Note: To discover Symmetrix DMX/V-Max volumes on an ESX 3.0 host, set the SPC-2 bit. 7. In Balance, select Discovery > Multiprovider. 8. Add the Symmetrix as a Symmetrix multiprovider. 3/6/1233
