This document describes system
requirements for the HP Network Node Manager i Software Smart Plug-in
Performance for Metrics (iSPI Performance for Metrics) and Network Performance
Server (NPS) version 9.11.
The NPS stores, aggregates, and provides reports for collected performance
data. It is the foundation for operational reports on NNMi. Other iSPIs rely
upon the NPS for report presentation functionality. The iSPI Performance for
Metrics adds the performance management capability to NNMi by analyzing,
processing, and aggregating a range of standard metrics collected by NNMi from
different network elements.
This document provides information about supported deployment configurations
that is not found in Release Notes or the NPS Installation Guide. When you are
ready to install the product, refer to the installation guide. The installation
guide is provided in Adobe Acrobat (.pdf) format on the product's installation
media. Installing the NPS copies the installation guide to the Docs directory.
You can install the NPS on a dedicated system,
separate from NNMi, or you can install it on the same system as NNMi. Before
installing the NPS and your iSPIs, make sure that your system meets the
following minimum requirements. Note the following points:
·
If you are upgrading
from the version 9.00 installation of iSPI Performance for Metrics, check the
hardware tables below for the latest requirements and see the HP Network Node
Manager i Software Smart Plug-in Performance for Metrics/ Network Performance
Server Installation Guide for instructions and
available upgrade paths.
·
The data directory
(NNMDataDir) will contain the bulk of the collected and aggregated data and as
such should be on the fastest and largest disk partition. For UNIX platforms,
this will be /var/opt/OV.
·
By default, the NPS
stores hourly aggregated data for 70 days. In addition, it stores very fine
grain, as collected, data in an archive table. The default retention period for
this type of fine grain data is 14 days. Most of the required disk space for
the iSPI is consumed by this detailed archive data storage. To change retention
periods from the default, use the configuration utility. The maximum
configurable retention period is 400 days. You can modify the settings for
hourly and archive table retention independently of each other, but the hourly
retention should always be equal to or greater than the detailed archive
retention period. Care should be taken to monitor the disk space usage on the
system after a change to this parameter. The tables below quote disk space
requirements for an out of the box system as well as one with retention at the
maximum.
·
These hardware
recommendations are a guideline only, based upon the use of the HP Network Node
Manager i Software Smart Plug-in Performance for Metrics (iSPI Performance for
Metrics) package. They do not take account of additional factors which may
affect the sizing of your application—such as the installation of the iSPI
Performance for Traffic, or additional custom collection reporting which may be
configured after installation. Every installed package using NPS for reporting,
and every custom collection with reporting enabled, will require additional
disk and processing capacity on the NPS system.
·
The NPS 9.11 does not
support the application failover feature. However, you can use the NPS with an
NNMi management server that has been configured for application failover. If
the NNMi management server is configured for application failover, you must
install the NPS on a dedicated server (and not on the NNMi management server).
·
NNMi has the ability to
discover topology elements such as nodes and interfaces, but not all discovered
elements will have performance data collected and reported upon. The numbers
quoted below relate only to performance polled elements.
·
The figures in the
tables below quote hardware requirements for an NPS running with a 5 minute
polling frequency. The number of polled interfaces and components is stated for
each scale. Example: 130k/130k means 130,000 interfaces and 130,000 component
sensors simultaneously.
o
Higher polling
frequencies will result in more data. So 400K interfaces at 5 minutes results
in the same number of collected data points as 80K interfaces at 1 minute
polling frequency.
o
Custom, user-defined
collections will result in additional storage requirements.
o
Adding other iSPIs to
your platform, such as iSPI Performance for Quality Assurance, iSPI for IP
Telephony, or iSPI for MPLS, will result in additional storage and processing
requirements for the NPS.
o
Monitor disk usage and
processing performance on the system on a daily basis after introducing a new
custom collection or iSPI.
The table below outlines the requirements for CPU, RAM
and disk space when NNMi and the NPS are on the same system. Note that the CPU,
RAM, and Disk figures represent the total requirements for the system and
include the combined capacity required for NNMi and the NPS. You must ensure
that this host also meets any additional criteria defined in the NNMi support
matrix.
NOTE:
·
When the NPS is
installed on a system that hosts NNMi, half of the system RAM will be consumed
by the NPS. The figures below for RAM resources take account of the combined
needs of NNMi and NPS and are especially important when running the NPS with
several iSPIs providing data.
·
Once installed, you can
use the Managed Inventory report to see the variety of collected elements for
each iSPI. For example : looking at the count of distinct Qualified
Interface Names in the Interface Health Managed Inventory
report will tell you how many unique interfaces have had performance data
collected within the selected time period.
·
While it is a supported option
to have NNMi and NPS on the same system for ‘Large’ scale environments, it is
recommended that the NPS is installed on a separate, standalone system.
·
HP does not support the
NPS being installed on the same server as NNMi for ‘Very Large’ scale environments.

If you plan on installing the NPS on a separate
machine from NNMi then you should ensure the following criteria are met. Note
that NPS sizing requirements are driven by the amount of data generated by the
custom collections and iSPIs which will supply it. The references provided in
this document for sizing and scalability are a guideline only and are based
upon the Metrics SPI, using the number of interfaces and node components that
NNMi is polling for performance data. - the total number of interfaces or
components discovered by NNMi is not relevant for this system. Enabling
performance polling on NNMi will have an impact on the NNMi system itself so
ensure that your NNMi host meets the criteria described in the section below as
well as any criteria defined within the NNMi support matrix.

·
IPv6 is not supported on Windows operating
systems.
NOTE:
·
Anti-virus and backup software
can interfere with the operation of the NPS if the software locks files while
the NPS is running. Any application that locks files should be configured to
exclude the NPS install and data directories (on Windows 2003, C:\Documents and Settings\All Users\Application
Data\HP HP BTO Software\NNMPerformanceSPI;
or on Windows 2008, C:\ProgramData\HP\HP
BTO Software\NNMPerformanceSPI).
·
Windows 2008 includes
the concept of User Access Control (UAC). Users who are part of the
Administrator group may not have full Administrator privileges. All scripts and
commands associated with NPS will detect and warn if the user is not elevated –
they should be run with full Administrator access. To achieve this, right-click
on the Command Tool icon and choose ‘Run as Administrator.’
