Includes customizable reports and scorecards that offer best practices, analyze trends, and highlight performance problems.

6 6 OnCommand Balance Installation and Configuration Guide Balance licenses Two types of licenses are available for Balance: an evaluation license, and a Controller license for NetApp storage systems. The software licenses have these characteristics: Evaluation: This is a Controller license that enables you to evaluate Balance for use in your environment. Please contact your NetApp Sales representative for a Balance evaluation license. Controller: This license applies to NetApp storage systems only, and supports Data ONTAP 8.1 or later operating in 7-Mode and clustered Data ONTAP or later. For storage systems running Data ONTAP 8.0 or earlier, such as 7.3, you must manually verify the license in Balance. A Capacity license, which applies to both NetApp and non-netapp storage systems, is supported if you purchased the license before its end of availability. Capacity licenses are based on the storage capacity in terabytes (TB) that you plan to monitor in Balance. Each time you apply a storage system to the Capacity license, the storage system capacity is subtracted from the total capacity purchased. When the total license capacity has been used up, you can purchase more capacity for adding additional storage systems. Note: NetApp V-Series systems running Data ONTAP software operating in 7-Mode are supported using Capacity licensing only. To apply a new Capacity license key, you can open your license file in a text editor, copy the entire character string into the license key field on the Administration - License page, and click Continue. As of Release the Capacity license was eliminated. If you purchased a Capacity license prior to that, see the Interoperability Matrix Tool (IMT) to check support for your storage system. Questions you can answer using OnCommand Balance Storage and IT administrators can use OnCommand Balance to gain visibility into the overall health of their data centers, troubleshoot performance bottlenecks, optimize resources that are over-utilized or under-utilized, and predict performance impact to new or existing workloads when planning to add or change resources. The following questions can be answered: Troubleshoot issues Is the source of the issue at the virtual machine (VM), server, or storage? Which workloads are victims and which are bullies? Which servers have misaligned storage? Optimize performance How much headroom do I have? Where can I put my VM or application for best performance? Can I reclaim memory, CPU, or storage resources?

8 8 OnCommand Balance Installation and Configuration Guide Balance installation requirements Before deploying the Balance virtual appliance (VA), you must determine the appropriate minimum resource requirements for your environment and ensure that the VMware ESXi Server and proxy host meet minimum requirements. The minimum resource requirements for the ESXi Server on which you deploy the virtual appliance (VA) increase based on the number of servers you plan to monitor. To deploy the VA, you can use the VMware vsphere Client. Related references Virtual machine host requirements on page 8 Virtual machine resource guidelines on page 9 Balance Proxy host requirements for NetApp on page 9 Balance scalability limitations on page 12 Virtual machine host requirements The VMware ESXi server that will host the virtual machine (VM) must meet minimum resource requirements. Review these requirements before deploying the VA. Resource ESXi Server Network Virtual CPUs Virtual Memory Disks Minimum Requirements Hardware and software must be 64-bit. 1 Gigabit Ethernet connection for fastest installation (optional). By default, the VM uses DHCP to communicate with the IP network GHz 4 GB With this amount of memory, you can add a maximum of 3 proxies to Balance. Increase the memory to twice this value or higher to add more proxies. At least 5 disk spindles in RAID-DP or other RAID array. During an upgrade, Balance requires a minimum of 50 percent free disk space. Balance uses the free portion of the disk to back up the original database (the used portion of the disk). To view the percentage of Capacity Used, select Admin > Configuration > Data growth.

9 Balance installation requirements 9 Resource Storage Minimum Requirements Data store requires at least 205 GB of disk capacity, which includes an extra 5 GB for VM memory and additional files (for example, swap). Refer to the virtual machine resource recommendations for the minimum number of disks required. Note: To optimize performance when installing Balance, there should be no memory limit set on vcenter OCB appliances. Virtual machines running Balance should be set to operate at their full RAM allocation. If performance becomes slow, reset the limit on VMs to use their maximum RAM allocation. Virtual machine resource guidelines The virtual machine (VM) resource guidelines listed here are based on the number of servers you plan to monitor. Additional virtual CPUs can be added through the vsphere Client. The VM has a minimum memory reservation of 4,096 MB (default). If this amount of memory is not available on the ESXi Server, the VM might not power on. The VM offers support for 4, 8, 12 or 16 GB of RAM. The table below lists the tested configurations.

14 14 OnCommand Balance Installation and Configuration Guide Installing your OnCommand Balance software The installation process contains three steps: downloading the virtual appliance (VA) installation file, deploying the VA, and performing the initial configuration. You download the VA as an OVA installation file from the NetApp Support Site. You need a customer account to access the site. You also need to be familiar with the operations of the VMware vsphere Client to deploy the OVA installation file that creates the virtual machine (VM). After the initial configuration using the vsphere Client, you can copy the IP address for your new VM into a supported browser and then start using the software to monitor your NetApp storage systems. Downloading the installation file To set up the software installation, you need to download the virtual appliance (VA) installation file and then use a VMware vsphere Client to deploy the file to a VMware ESXi Server. The VA is available in an OVA file. Steps 1. Download the OVA installation file from the NetApp Support Site. You need to log into the Support website to access this file. 2. Save the OVA file to a local or network location that is accessible to your vsphere Client. 3. Verify the checksum on the Download page to ensure you have the correct installation file. Installing Balance To install Balance, you use a VMware vsphere Client to deploy the virtual appliance (VA) to a VMware ESXi Server. The vsphere Client converts the VA to a virtual machine (VM). Steps 1. In the vsphere Client, select File > Deploy OVF Template. 2. Complete the Deploy OVF Template wizard to deploy the VA. Note: For the VM disk format, select Thin Provisioned. Thin provisioning allows the Balance database to efficiently grow to the maximum available capacity as you add resources to your data center. For more information, see the vsphere online help. 3. After the VA has successfully deployed to the ESXi Server, power on the VM.

15 Note: If your vcenter has multiple networks specified, check the VA configuration to confirm that the correct network is selected. 4. In the vsphere Client, install VMware Tools for the VM. Installing your OnCommand Balance software 15 A 90 second timeout message is displayed on the Balance console enabling you to install VMware Tools. If you do not install VMware Tools during the 90 second timeout, Balance deployment continues without installing VMware Tools. If you do not install VMware Tools during this initial deployment, or if VMware Tools fail to install, you must install VMware Tools manually as described in the substeps below. Note: If VMware Tools continues failing to install, reboot the appliance a second time, then manually install VMware Tools from the console. 5. In the vsphere Client, click the Console tab to monitor the status as the VM powers up, Balance starts, and Balance uses DHCP to assign an IP address to the VM. If DHCP is not detected, you are prompted to specify the network settings for assigning an IP address to the VM. You enter this IP address in a web browser to access and use the Balance web client to configure the VM. If you did not install VMware Tools in step 4 above, install the VMware Tools manually: a. In the vsphere Client, select the Balance VM and install VMware Tools. b. Select the Console tab, and click inside the console to log in. Note: The default username and password is netapp (all lowercase). You should change the default credentials when you log in for the first time. c. Choose option 2 for Hypervisor Tools, then choose option 1 to install. d. When prompted, type y to continue. e. When the installation has completed, exit the menu. Note: During the tools installation, informational messages might display. You can ignore these messages and continue through the installation. After the installation has completed, use the vsphere Client to check the status of the tools. After you finish Configure the VM.

To enable a password prompt, change NOPASSWD to PASSWD.

27 Configuring resources for data collection 27 Configuring RSA authentication for Linux and UNIX servers To use RSA authentication for monitoring Linux or UNIX servers, including self-monitoring of the Balance virtual machine (VM), you need to create RSA keys and RSA credentials in Balance. Steps 1. Create the following RSA keys: To monitor (self-monitor) the Balance VM, use the read-only self-monitor credentials. To monitor Linux or UNIX servers, create an RSA keypair using the ssh-keygen program from the read-only Balance user account. Do not use a third-party key generator, such as PuTTy, to create the RSA keys. 2. In the user directory on each Linux or UNIX server you want to monitor, or on the Balance VM, copy or rename the id_rsa.pub key to.ssh/authorized_keys. 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. 5. If you are using a read-only user account, ensure that the sudoers file on each Linux or UNIX server contains the correct installation paths to the installed volume managers. NetApp storage system requirements The NetApp storage systems you want to add to Balance must meet minimum requirements. NetApp storage systems with these requirements: Clustered Data ONTAP software. Cluster administrator account with ONTAPI Application access and the read-only role. This account provides read-only administrator access to the cluster. Cluster Management IP (LIF) to discover all nodes in the cluster. Enabling discovery of Data ONTAP operating in 7-Mode with a user account For NetApp storage systems with Data ONTAP operating in 7-Mode, you can use a user account instead of a standard administrator (root) account to give Balance access to your storage systems. About this task For storage systems with Data ONTAP operating in 7-Mode, you can use a command line interface and copy the command in this procedure to create the special user role.

28 28 OnCommand Balance Installation and Configuration Guide Steps 1. Log into Data ONTAP on the NetApp storage system. Note: In Balance, on the Storage page for a selected storage system, you can click Console and use the command line interface. 2. Enter the following command to create the user role: useradmin role add balance_user -a login-http-admin,api-system-get-info,api-system-get-version,apilicense-list-info,api-fcp-adapter-list-info,cli-fcp,api-cf-status,apidisk-list-info,api-aggr-list-info,api-volume-list-info,api-volume-listinfo-iter-start,api-volume-list-info-iter-next,api-volume-list-infoiter-end,api-volume-get-root-name,api-lun-list-info,api-lun-getgeometry,api-lun-map-list-info,api-qtree-list,api-lun-get-serialnumber,api-lun-stats-list-info,api-system-cli,cli-rdfile,cliifconfig,api-vfiler-list-info,security-api-vfiler,api-nfs-status,apinfs-exportfs-list-rules,api-nfs-exportfs-list-rules-2,api-cifsstatus,api-cifs-share-list-iter-start,api-cifs-share-list-iter-next,apicifs-share-list-iter-end,api-perf-object-list-info,api-perf-objectcounter-list-info,api-perf-object-get-instances,api-perf-object-getinstances-iter-start,api-perf-object-get-instances-iter-next,api-perfobject-get-instances-iter-end,api-useradmin-user-list,api-useradmingroup-list,api-useradmin-role-list where balance_user is the name of your user role. Note: If you previously added a balance_user, you only need to update the role. You can replace add with modify. Adding the user role requires all commands to be on one line. You may want to copy the commands to a.txt file, with word wrap disabled, fix any missing hyphens, and then copy into the Use Command Line field. 3. Enter the following command to create the user group: useradmin group add group -r balance_user where group is the name of the user group. 4. Enter the following command to add the user role to the user group: useradmin user add balance_user -g group Note: For NetApp clusters, only enter the FQDN or IP address for one of the storage systems; both are monitored and summarized information displays for the NetApp cluster. NetApp system requirements for Balance In order to discover and collect statistics, some systems have specific requirements. Apply the controller license to V-Series systems.

29 Discover V-Series systems. Configuring resources for data collection 29 When Balance discovers NetApp V-Series systems, it discovers the local disk groups on the systems. For the local disk groups on V-Series systems, Balance can display the storage capacity, disk count, disk model, RAID level, and the topology mapping to other resources in the data center. Balance does not display this information for disk groups from back-end storage. Analysis for NetApp V-Series systems is limited to the local storage resources on the physical system. It does not include the resources from the back-end storage system. To view discovery and statistical data for the back-end storage, go to the Storage page and select the name of the storage system. Storage virtualization software Balance supports virtualization software for HMC with specific software installed on each VIO server. HMC Virtual IO Servers (IBM LPAR) requirements To discover HMC servers, VIO servers, and the associated AIX logical partitions (LPAR), Balance requires specific software to be installed on each VIO server. There are two options to choose from when setting up communication between Balance and HMC VIO servers: You can use an account with root privileges for accessing the HMC and VIO servers and discovering the associated AIX logical partitions (LPAR). You then add the HMC and VIO servers to Balance to monitor the AIX LPARs. You can use a user account to discover the HMC servers, VIO servers, and the associated AIX logical partitions (LPAR). You configure a sudoers file for accessing the VIO servers and copy the file to each VIO server you want to discover. You then add the HMC and VIO servers to Balance to monitor the AIX LPARs. Enabling HMC and VIO discovery using root You can use an account with root privileges for accessing the HMC and VIO servers and discovering the associated AIX logical partitions (LPAR). You then add the HMC and VIO servers to Balance to monitor the AIX LPARs. Before you begin Balance has root access for the following resources: HMC Server: hscroot and password VIO Server: username (padmin) and password (must be the same for all VIO servers) AIX LPARs: username and password

On the Discovery Unmonitored Servers page, select the check box next to each AIX LPAR you want to monitor and click Monitor Selected. You will need to select the appropriate credentials for each AIX LPAR. Each AIX LPAR moves to the Discovery Servers page. Enabling HMC and VIO discovery using a user account You can use a user account to discover the HMC servers, VIO servers, and the associated AIX logical partitions (LPAR). You configure a sudoers file for accessing the VIO servers and copy the file to each VIO server you want to discover. You then add the HMC and VIO servers to Balance to monitor the AIX LPARs. Before you begin Balance has credentials for the following resources: HMC Server: username and password. The username must be a member of the staff group. The recommended HMC Task Role is "hmcviewer." VIO Server: username and password (must be the same for all VIO servers you plan to discover) AIX LPARs: username and password

31 Configuring resources for data collection 31 Latest ODM driver installed on each VIO server for the servers to communicate with each connected storage array. SSH installed on the HMC and VIO servers. Balance uses an SSH login using a password or key exchange to communicate with HMC and VIO servers. Sudo installed on each VIO server. You can download the required version of sudo here: About this task Balance uses the provided aixhba utility to map the data topology from each VIO server to the connected storage arrays. The sudoers file you copy to each VIO server contains entries that specify the location of the aixhba utility file. Steps 1. Use the visudo command to edit the sudoers file on each VIO server to include the following entries for running the aixhba utility on each VIO server. Example The entry you choose depends on your security requirements (password or no password). Defaults!env_reset username hostname=passwd: /tmp/aixhba or Defaults!env_reset username hostname=nopasswd: /tmp/aixhba where: username is the username for accessing the VIO server. hostname is the fully-qualified name (FQDN) or IP address of the Balance virtual machine (VM) accessing the VIO server.
