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

The recommendations listed in this support matrix apply to NNMi and NNM iSPI for IP Telephony running under the default settings. Installing additional NNM iSPIs might require additional hardware beyond what is mentioned below. If you want to run other NNM iSPIs, review each NNM iSPI support matrix before determining the total hardware requirements for your environment

Below are the tiers of managed network environments and the hardware required by the NNM iSPI for IP Telephony for supporting these environments. Managed environments bigger than the largest tier are not supported without additional HP approval.

Note: The system sizing details mentioned in the following tables are additional recommendations for your NNM iSPI for IP Telephony deployment over and above what is mentioned in other prerequisite product support matrix documents such as NNMi 9.10 Support Matrix and NNM iSPI Performance for Metrics/NPS Support Matrix.

The NNM iSPI for IP Telephony hardware requirements mentioned in the following tables are in addition to NNMi hardware requirements mentioned in the NNMi Support Matrix.

Before installing the NNM iSPI for IP Telephony, make sure that your system meets the following minimum requirements:.

• The RAM Requirement mentioned in the tables below is an approximate number to help you get started with the sizing of the system. However, if you are planning to install the iSPI Performance for Metrics/NPS on the same system, you must ensure that the physical RAM is greater than two times that of the combined Xmx values of NNMi, the NNM iSPI for IP Telephony, other content iSPI s (if installed on the system), the NNM iSPI Performance for Traffic Master Collector (if installed on the system), the NNM iSPI Performance for Traffic Leaf Collector (if installed on the system), and the NNM iSPI Performance for Quality Assurance (if installed on the system). You must also consider the consumption of memory in segments apart from the memory consumption by various heap segments. In addition, you must also consider consumption of memory by the operating system, applications from HP which are not listed in this document, and applications from other vendors.

• If you are planning to install the NNM iSPI Performance for Metrics/NPS on a separate system, you must ensure that the physical RAM is greater than that of the combined Xmx values of NNMi, the NNM iSPI for IP Telephony, other content iSPI s (if installed on the system), the NNM iSPI Performance for Traffic Master Collector (if installed on the system), the NNM iSPI Performance for Traffic Leaf Collector (if installed on the system) and the NNM iSPI Performance for Quality Assurance (if installed on the system). You must also consider the consumption of memory in segments apart from the memory consumption
  by various heap segments. In addition, you must also consider consumption of memory by the operating system, applications from HP which are not listed in this document, and applications from other vendors.

• It is recommended that you provision 4 GB or more of RAM for the operating system and the other applications on the system.

• Make sure that you have reviewed the support matrix document for both NNMi and the NNM iSPI for Performance Metrics/NPS to understand and note various important details about system sizing that are applicable for the NNM iSPI for IP Telephony deployment in your environment along with pre-deployed NNMi, NPS and any other applications from HP or other vendors.

Disk Space Requirements on the iSPI Performance for Metrics/NPS System for Retention of Reporting Data Generated by the NNM iSPI for IP Telephony

If you decide to enable various reporting in the NNM iSPI for IP Telephony, you must provision for incremental disk space usage on the system for long term storage of the reporting data created by the NNM iSPI for IP Telephony and stored in the NPS database. You must make such a provision for the following scenarios:

• The NNM iSPI Performance for Metrics/NPS is installed on the same machine where NNMi and the NNM iSPI for IP Telephony are installed
• The NNM iSPI Performance for Metrics/NPS is installed on a separate system

See the NNM iSPI Performance for Metrics/NPS Support Matrix document for more information about minimum system requirements (including those for disk space) for appropriately evaluating the disk space requirements.

As a sample estimate, consider the following for a global manager instance of the NPS, which is supplied with the reporting data by a global manager instance of the NNM iSPI for IP Telephony:

• For the medium tier: The NPS database must be able to accommodate 12 TB of the reporting data generated by the NNM iSPI for IP Telephony after 400 days of operation.
• For the large tier: The NPS database must be able to accommodate 20 TB of the reporting data generated by the NNM iSPI for IP Telephony after 400 days of operation.

Again consider the following for a regional manager instances or single system standalone instance of the NPS, which is supplied with the reporting data by a regional manager instance or single system standalone instance of the NNM iSPI for IP Telephony:

• For the large tier: The NPS database must be able to accommodate 3 TB of the reporting data generated by the NNM iSPI for IP Telephony after 400 days of operation.
• For the very large tier: The NPS database must be able to accommodate 5 TB of the reporting data generated by the NNM iSPI for IP Telephony after 400 days of operation.

Additional Information

• The NPS database table spaces planning during the deployment is extremely important. For the medium and large tiers, it is recommended that you allocate approximately 100 GB for the TEMP space and an appropriate amount of disk space for the USER space that is your primary container of data. Make sure you refer to the NPS Support Matrix document and other NPS documents for database sizing. Plan and execute these sizing tasks before starting to use the product, or in some cases, before installing and configuring the NPS.
• Specifically for the USER space in the NPS database, periodic checks on the disk utilization is extremely important. This will help you proactively plan and execute database and disk sizing tasks in a way to prevent the loss of your valuable reporting data or to prevent permanent instability of the system. You can again perform these periodic checks by using various database sizing utilities provided by the NPS. See the NPS Support Matrix document and other NPS documents for database sizing.
• You might like to disable the performance polling of a large number of NNMi interfaces and component objects in your environment if you are not interested in reports on interface and component health. Alternatively, you might like to tune the retention of aggregated interface and component health metrics in reporting packages to a value that is smaller than the default 400 (days). You can also apply both the measures at the same time to use your disk space optimally. Refer to the NNM iSPI Performance for Metrics/NPS documentation for reference information on how to accomplish these tasks.

You can use this information along with the iSPI Performance for Metrics/NPS Support Matrix document for appropriate sizing of the systems involved.

Memory, CPU Requirements on the NNM iSPI Performance for Metrics/NPS System for Processing of the Reporting Data Generated by the NNM iSPI for IP Telephony

If you decide to enable various reporting options for the NNM iSPI for IP Telephony, you must provision for incremental memory and CPU usage on the system for the NNM iSPI Performance for Metrics/NPS, which is supplied with the reporting data created by the NNM iSPI for IP Telephony. You must make such a provision for the following scenarios:

• The NNM iSPI Performance for Metrics/NPS is installed on the same machine where NNMi and the iSPI for IP Telephony are installed
• The NNM iSPI Performance for Metrics/NPS is installed on a separate system

See the NNM iSPI Performance for Metrics/NPS Support Matrix document for more information on minimum system requirements (including those for the CPU and memory) for appropriately evaluating the CPU and memory requirements and taking adequate measures before deploying the NNM iSPI Performance for Metrics/NPS.

• As a general rule, for co-located installations (where the NPS and NNMi are installed on the same system), the physical RAM size of the system must be at least twice as much as the total Heap Size requirements from the NNM iSPI for IP Telephony, NNMi, other iSPI product (or product components), and other applications installed on the system (leaving aside around 4 GB for the operating system).
• For the other type of installation (where the NPS is not installed on the NNMi management server), the physical RAM size of the NPS system must be at least twice as much as the total Heap Size requirements from the other iSPI products or product components and other applications installed on the system (leaving aside around 4 GB for the operating system).
• For large and very large tier deployments of the standalone instance of the NNM iSPI for IP Telephony, and for medium and large tier deployments of all global manager instances of the NNM iSPI for IP Telephony, install the NPS on system other than the NNMi management server.

Also, make sure that the various parameters related to the NPS database and BI server are appropriately tuned for your scale. Default settings created by the NPS installation for these parameters might not be appropriate for the scale of your deployment.

• Some of the important parameters for the NPS database server are the in-memory caches used by the database engine. These parameters must have correct settings configured to avoid performance problems in report execution.
• Similarly, parameters for the NPS BI server must be tuned appropriately by directly interacting with the NPS console or by the scheduled background execution of the reports submitted to the NPS BI server.
  
  Finally, you might like to disable the IP Telephony reporting packages for a specific IP Telephony vendor (Avaya or Cisco) if you are not interested in those reports. You can accomplish this by uninstalling the NPS report extension pack containing the specific reporting packages from NNM iSPI for IP Telephony. Refer to the iSPI for IP Telephony and NPS documentation for instructions on uninstalling a specific extension pack.

Tuning the jboss Memory

To change the jboss Maximum Java Heap Size (‑Xmx) or other Java Virtual Machine parameters, follow these steps:

1. Stop the IP Telephony process by the following command: ovstop –c iptjboss
2. Edit the nms-ipt.jvm.properties file available in the /var/opt/OV/shared/ipt/conf directory.
3. Update the Maximum Java Heap Size to the required value. For example, a snippet of the nms-ipt.jvm.properties file appears as:
   #
   # JVM Memory parameters
   #   ‑Xms: Initial Java Heap Size
   #   ‑Xmx: Maximum Java Heap Size
   #
   ‑Xms1024m
   ‑Xmx2048m
4. Start the IP Telephony process by the following command: ovstart –c iptjboss

For more information related to NNMi values, see the NNMi Support Matrix.

Operating System

HP-UX

• HP-UX 11i v3
• Kernel configuration (verify with /usr/sbin/smh)
  • Verify kernel parameters in the "Kernel Configuration/Tunables" section:
    • nproc: add 50
    • max_thread_proc = 2048
    • nkthreads = 10000
• System Configuration
  • Verify using swapinfo that the system has a sufficient amount of swap as documented in Virtual Memory/Swap Space.
• Operating System Kernel Patches
  The following HP-UX 11iv3 operating system patches are required (or newer if the patch has been superseded).  You can verify patches on HP-UX by running
          /usr/sbin/swlist -l fileset -a patch_state *.*,c=patch | grep -v superseded
  This list does not include Java patches (see next bullet), but only the list of OS-level patches. The following patches are required:
  • PHKL_36054
  • PHKL_36261
  • PHKL_36872
  • PHKL_37184
    
    On HP-UX run the following command to verify patches:
    /usr/sbin/swlist -l fileset -a patch_state *.*,c=patch | grep -v superseded
• Run HPjconfig HP-UX 11i system configuration tool to validate the system configuration. HPjconfig can be downloaded from www.hp.com/go/java.  To install:
  • On your HP-UX system, gunzip and untar the .tar.gz file as follows:
    gunzip HPjconfig-3.1.00.tar.gz
    tar -xvf HPjconfig-3.1.00.tar
  • To start HPJconfig:
    Change to the directory you installed the HPjconfig files.
    There are two ways you can run HPjconfig, GUI and non-GUI mode. Enter one of the following commands:
        java -jar ./HPjconfig.jar (The default HPjconfig GUI)
      java -jar ./HPjconfig.jar -nogui -help
        (The -help command lists options that you can use in non-GUI mode)
    
  • To list missing patches in non-GUI mode:
    java -jar ./HPjconfig.jar -nogui -patches -listmis
    This will validate kernel configuration and patch levels

Solaris

• Oracle Solaris 10 SPARC
• Note: Solaris on Intel Architecture is not supported
• Operating System Patch. The Solaris patch 142242-04 (or later if the patch has been superseded) is required.
• The shared memory must be updated. Update the /etc/system entry using an editor as follows:
  set shmsys:shminfo_shmmax=1073741824

Linux

• Red Hat Enterprise Server AS 5.2 (or later minor version through 5.x)
• Red Hat Enterprise Server ES 5.2 (or later minor version through 5.x)
• NOTE: Red Hat 5.5 is required for CPU chips with more than 4 cores on a single chip (Do not confuse this number with the total number of cores; this number is
  just the cores per chip.)
• NOTE: SUSE Linux Enterprise Server is not supported.
• The default size of kernel.shmmax may be too small for the embedded database to operate after a reboot (as reported by ovstatus -c nmsdbmgr).  To validate, run /sbin/sysctl –a | /bin/grep kernel.shmmax.  If this is less than 300 MB (300000000), then it must be modified. To change the value, run:

  /sbin/sysctl –w kernel.shmmax=300000000
  To make this change permanent (after a reboot), edit the /etc/sysctl.conf file and add the following entry:

  kernel.shmmax = 300000000

• See the installation guide for the dependency on the 64-bit libstdc++ libraries.

Virtual Memory/Swap Space

• Recommended size is at least equal to the physical memory
• Verify and adjust the virtual memory:
  • HP-UX: To verify, use the swapinfo command. To adjust, use the shm or swapon command.
  • Linux: To verify, use the cat /proc/meminfo | grep Swap command. To adjust, use the parted and mkswap commands.
  • Solaris: Use the swap command.
