Services & Solutions


Network assessments offer a holistic view of your multivendor environment and a reference point for how your infrastructure is performing. Our experts can pinpoint and expose issues in your network using specialized software and diagnostic tools. These unbiased and insightful analytics are aggregated into comprehensive reports that can include recommendations on how to improve performance, optimize devices and remediate problems.
Network Topology Assessment

Is your network complex and coiled? Dell can perform a detailed audit and inventory of all multivendor devices in the network to provide visibility and identify configuration issues.

Network Optimization Assessment

Many networks are a multivendor patchwork of devices not running at their optimal state. We can analyze devices from all leading vendors and make recommendations to optimize the entire multivendor design, fine-tune devices and maximize performance of the holistic environment.

Application Performance Assessment

When business applications and databases begin to show signs of latency or completely shut down, we can conduct a comprehensive analysis to uncover performance issues, isolate problems and accelerate troubleshooting of the enterprise infrastructure and software applications.

VoIP Assessment

Moving to a Voice-over-IP (VoIP) solution requires the right network infrastructure to support real-time voice protocols. Simulated load testing, analysis and review can identify the next steps to building a VoIP platform or fixing issues of an existing one.
