Deployment Capacity and Optimization Best Practices

Introducing Capacity and Optimization for
DX NetOps Spectrum
DX NetOps Spectrum
is one of the most powerful tools available to monitor your network infrastructure. As always, with power comes responsibility. Like a Formula One race car,
DX NetOps Spectrum
is a highly capable system. However, both the race car and the software are highly susceptible to their operating environment and to the control of their human drivers. Just as a rain-soaked track can end a race, a lack of system resources or an over-subscribed system workload can sideline
DX NetOps Spectrum
.
In this section, we have captured the best practices and advice to help you keep
DX NetOps Spectrum
performing at its highest levels. These best practices are derived from systematic, controlled performance testing, and from years of real-world experience supporting our global customer base.
In highly dynamic IT environments, monitoring the capacity of your systems and optimizing your
DX NetOps Spectrum
deployment cannot be a one-time task. Regular, periodic reviews are required to keep
DX NetOps Spectrum
operating optimally in larger environments (more than 1,000 monitored devices).
Prerequisites
To understand the advice that we offer in this section, you must be familiar with
DX NetOps Spectrum
concepts, architecture, and terminology. Specifically, we recommend that any
DX NetOps Spectrum
administrator take the following training courses:
  • DX NetOps Spectrum
    : Operator 200
  • DX NetOps Spectrum
    : Foundations 200
  • DX NetOps Spectrum
    : Optimization and Customization 300
In addition, we recommend
DX NetOps Spectrum
administrators must be familiar with the
DX NetOps Spectrum
component documents for the various applications and integrations that are heavily used in their environment.
This section replaces the SpectroSERVER Performance Administration Guide.
Getting Started
The best place to start is to request a sizing estimate that is based on your deployment intentions or existing deployment. You can request a sizing estimate through your technical sales contact before the purchase, or through Support. Support must perform the most advanced and detailed sizing for an existing deployment. Many details that are needed for the Support type of sizing are not available when sizings are performed during the sales cycle. The Sizing estimation requires some key pieces of data to estimate the number of SpectroSERVERs required to manage your workload.
Managing your environment with fewer than the recommended number of SpectroSERVERs risks instability or performance problems that affect a production deployment. Validate the system utilization metrics early and regularly in a production deployment. This validation ensures that the resource utilization predictions from the Sizer are accurate. Many features of
DX NetOps Spectrum
are not accounted for in the predictive model of the Sizer. The Sizer works from a steady state, without major faults, reconfigurations, or other sources of variability. Therefore, validation is an important activity post-deployment.
The sizing guidelines and best practices in this section help
DX NetOps Spectrum
servers operate below the capacity of your system and operating environment. Do not consume your total capacity. The
DX NetOps Spectrum
workload is dynamic and can vary greatly based on usage patterns, periodic automated operations, or network outages. An optimally tuned
DX NetOps Spectrum
server does not exceed 40%of CPU capacity or 75% of process RAM or physical system total RAM. The spare capacity enables periodic workload increases.
