Installation Notes

The NNM iSPI Performance for QA 10.01 release is a patch release. Installation requirements, as well as instructions for installing NNM iSPI Performance for QA 10.01, are documented in the patch text file, which is available with the downloadable patch.

Note: After installing the patch, the new probe types are discovered, and device model column is populated only in the next discovery cycle. However, if you want them sooner, you must perform a rediscovery.

Hardware and Software Requirements

Before you install the NNM iSPI Performance for QA, make sure that your system meets the following minimum requirements:

Virtualization

Note: The Virtual environment must meet the x86-64 or AMD64 hardware requirements listed below.

Hardware

CPU, RAM, and Disk Space Requirements / Maximum Supported Managed Environment

Single System Managed Environment

The following table shows the requirements for the single system managed environment size. These requirements are in addition to the requirements for NNMi server:

Single System Managed Environment Size Recommended Hardware System Requirements 1
Approximate managed environment tier Max number of probes Max number of QoS interfaces Max number of iRA probes Max number of ping latency pairs Max number of combined probes, iRA probes, and QoS interfaces Number of concurrent users CPU (64-bit) x86-64 AMD642 RAM

Recommended Java heap size (Tuning the jboss Memory Size)3

 

Disk space for application installation ($NnmInstallDir)4 Disk space for operational database (data during execution) ($NnmDataDir)5
Entry 5,000 2,000 1,500 1,000 5,000 2 2 CPU Cores 4 GB 3 GB 2 GB 20 GB
Medium 30,000 12,000 10,000 3,000 30,000 10 4 CPU Cores 8 GB 6 GB 2 GB 60 GB
Large 50,000 20,000 40,000 5,000 50,000 15 4 CPU Cores 12 GB 8 GB 2 GB 80 GB

Caution: Running the NNM iSPI Performance for QA in an environment with probes or QoS interfaces or iRA probes far exceeding the supported maximum limit mentioned in the table above can lead to a database deadlock. If you intend to run the NNM iSPI Performance for QA in such an environment, you must configure discovery filters before the first discovery by NNM iSPI performance for QA to bring down the number of discovered probes or QoS interfaces or iRA probes to the supported limit.

Global Network Management Environment

The following table shows the requirements for the global network management environment size. These requirements are in addition to the requirements for NNMi server:

Global Network Management Environment Size Recommended Hardware System Requirements 1
Approximate managed environment tier Number of Regional Servers Max number of probes Max number of QoS interfaces Max number of ping latency pairs Max number of combined probes, iRA probes, and QoS interfaces Number of concurrent users CPU (64-bit) x86-64 AMD642 RAM

Recommended Java heap size (Tuning the jboss Memory Size)3

Disk space for application installation ($NnmInstallDir)4 Disk space for operational database (data during execution) ($NnmDataDir)5
Medium 4 120,000 50,000 10,000 120,000 10 4 CPU Cores 16 GB 12 GB 2 GB 80 GB
Large 9 250,000 100,000 20,000 250,000 15 8 CPU Cores 24 GB 20 GB 2 GB 100 GB

These values are approximate and reflect levels tested by HP. The number of currently discovered QA probes is displayed in the NNM iSPI Performance for QA "Help for NNMiSPI --> System information for iSPI Performance for QA" dialog. Managed environments bigger than these are not supported without additional HP approval.

1 Apart from the hardware system requirements of NNMi, this table specifies the additional hardware system requirements for the NNM iSPI Performance for QA product to be installed on NNMi management server.

2 Minimum of 2.5GHz for x64.

3 These recommendations are based on the environment size and object counts stated in this table. Polling fewer of a given object type might use less Java heap. Polling more of a given object type might require increased Java heap size as well as HP approval. For more details, refer to Tuning the jboss Memory Size section.

4$NnmInstallDir is configured during installation on Windows (C:\Program Files (x86)\HP\HP BTO Software\ by default), or on Linux ( /opt/OV/).

5$NnmDataDir is configured during installation on Windows Server 2008 (C:\ProgramData\HP\HP BTO Software\ by default), or on Linux (/var/opt/OV/).

These recommendations only apply to the NNM iSPI Performance for QA running under the default settings. If you intend to run any of the other NNM iSPIs, you must review each iSPI support matrix before determining the hardware you need.

The following are the recommendations for the QA Probes/QoS entities:

Network Performance Server (NPS)

The following table shows the requirements for the Network Performance Server (NPS) for different managed environment sizes. These requirements are in addition to the requirements for the NPS for the NNM iSPI Performance for Quality Assurance or any other iSPI that is installed. This is significantly affected by the changes in the configured retention period for the data queried by different extension packs.

Managed Environment Size Network Performance Server Minimum Hardware System Requirements a
Approximate managed environment tier Max number of combined probes, iRA probes, and QoS interfaces CPU (64-bit) x86-64 AMD64 RAM Disk space for storing the NNM iSPI Performance for QA data in the Sybase DB (the NPS database)
(<DataDir on the NPS system>)b

Disk space required for archiving the processed data for 2 weeks


(<DataDir on the NPS system >)c

Entry - Single Station 5,000 2 CPU Cores 12 GB

500 GB

30 GB
Medium - Single Station 30,000 4 CPU Cores 16 GB 700 GB 60 GB
Large - Single Station 50,000 8 CPU Cores 32 GB 1 TB 160 GB
Medium - GNM 120,000 16 CPU Cores 64 GB 2.5 TB 600 GB
Large - GNM 250,000 32 CPU Cores 96 GB 4 TB 1 TB

The disk space specifications in the table is meant to retain the data for a maximum period of 400 days. For higher retention period, we recommend you to allot more disk space for <NPS_Data_Dir>. See the NNM iSPI Performance for QA Deployment Reference to calculate the disk space required for <NPS_Data_Dir> by NPS.

a Apart from the hardware system requirements of NPS, this table specifies the additional hardware system requirements for the NPS system to build the NNM iSPI Performance for QA reports.

b Allocate raw disk partition for better performance.

c If the default data archiving period is more than 2 weeks, provision additional disk space proportionately.

Note: In large scale tier,  it is recommended to use Linux operating system for NPS at GNM as ETL process is observed to be slow on Windows.

Intelligent Response Agent (iRA)

You can configure up to 2500 iRA probes for each iRA instance. The number of HTTP/HTTPS probes must not exceed 10% of the maximum supported iRA probes. You can see iRA-based probes in the Probes inventory in the Quality Assurance workspace.

The following table shows the requirements for the Intelligent Response Agent (iRA) only when it is hosted on an independent server:

Intelligent Response Agent Minimum Hardware System Requirementsd

CPU (64-bit)
x86-64 AMD64

RAM
2 CPU Cores 500 MB

d There is no additional hardware requirement for the iRA when it is hosted on a server along with NNMi, the NNM iSPI Performance for QA, and any other iSPI.

Operating System

Note: The Intelligent Response Agent (iRA), available on the NNM iSPI Performance for QA media, is supported on all the operating systems listed here except for on SUSE Linux Enterprise Server.

Windows

Supported Version Notes

Linux

Supported Version

Tip: Red Hat does not support direct upgrades from Red Hat Enterprise Linux Server 5.x to 6.0.

Virtual Memory / Swap Space

Database

NNM iSPI Performance for QA can store its data using the embedded PostgreSQL database that is automatically installed when you install NNMi 10.01 or in the Oracle® database that NNMi uses. You must select the database that NNMi uses (PostgreSQL or Oracle) while installing the NNM iSPI Performance for QA. You cannot change the database type (PostgreSQL or Oracle) after installation.

NOTE: You cannot change from an embedded database to Oracle or back after installation.

High Availability

NNM iSPI Performance for QA can run on certain high availability systems with additional configuration. See the Deployment Reference for information about how to install and configure the NNM iSPI Performance for QA with high availability systems. The following configurations are supported on the NNM iSPI Performance for QA Supported Operating Systems:

Web Browser

Supported Web Browsers Running on a Remote Client System (for operational use)

Supported Web Browsers on the Local NNM iSPI Performance for QA Management Server System (for initial installation and configuration use)

General Web Browser Requirements

Adobe Flash Plug-in Player

The Real-time Line Graphs (Actions → Quality Assurance → Graphs) and the Performance Graphs, require the Adobe Flash Player Plug-in version 11.2.202.285 (or later minor version) on Linux, or version 11.7.700.202 (or later minor version) on Windows. The Adobe Flash Player is available from www.adobe.com/go/getflash/.

Tuning the jboss Memory Size

During installation, the recommended default maximum memory size of the jboss application server is configured in the nms-qa.jvm.properties file to 2GB. For improved performance in larger environments, it is recommended that you can increase this value as documented in CPU, RAM, and Disk Space Requirements.

The current Maximum Attemptable Memory value (adjusted with –Xmx) is available in the NNMi console with Help → System Information for iSPI Performance for QA. It is recommended that this –Xmx value not exceed the amount of unused physical RAM. If the jboss JVM's entire virtual memory space does not fit in physical memory, the operating system thrashes as jboss randomly accesses its memory.

You can approximate the amount of unused physical RAM available to jboss as follows: From the amount of physical memory, subtract the following amounts:

To change the jboss Maximum Java Heap Size (-Xmx) or other Java Virtual Machine parameters:

  1. ovstop -c qajboss
  2. Edit the nms-qa-jvm.properties file:
  3. Change the Maximum Java Heap Size to the required amount. For example, a snippet of the ms-qa.jvm.properties file looks like this:
    #
    # JVM Memory parameters
    # –Xms: Initial Java Heap Size
    # –Xmx: Maximum Java Heap Size
    # –Xss: Java stack size (default to OS-supplied value)
    #
    –Xmx2048m
    –Xms1024m

    Note: For Linux servers, if the Java heap size is greater than 4 GB, enable the -d64 flag. (To enable -d64 flag, uncomment #-64 flag in the nms-qa.jvm.properties file.)
  4. ovstart -c qajboss
