This IBM® Redbooks® Product Guide describes IBM Network Advisor Version 14.0. Although every network type has unique management requirements, most organizations face similar challenges managing their network environments. These challenges can include minimizing network downtime, reducing operational expenses, managing application service level agreements (SLAs), and providing robust security. Until now, no single tool was able to address these needs across various network types.
Under pressure to reduce costs and increase agility, organizations can get stuck in reactive mode, overspending through inefficiencies to keep their networks running. By standardizing and automating processes, however, network teams can proactively address availability and performance issues, and dramatically reduce costs.
To address this issue, the IBM Network Advisor software management tool provides simplified network management for today’s increasingly dynamic storage area network (SAN) fabrics. This single application can deliver end-to-end visibility and insight across network types by integrating with Fabric Vision technology. It supports SANs (including Gen 6 and Gen 5 Fibre Channel (FC) platforms), IBM FICON®, and other non-IBM, Brocade based FC networks. In addition, this tool supports comprehensive lifecycle management capabilities across different networks through a simple, seamless user experience.

Simplified network management for dynamic storage fabrics
IBM Network Advisor simplifies storage network management and helps organizations proactively diagnose and troubleshoot issues to maximize uptime, increase operational efficiency, and reduce costs. Customizable, browser-accessible dashboards represent data from discovered devices, including advanced diagnostic information that is delivered through integration with Fabric Vision technology. As network issues arise, teams can drill down through the interface for more details, and rapidly identify, diagnose, and troubleshoot problems before operations are affected.
Fabric Vision technology, an extension of Gen 6 and Gen 5 Fibre Channel, provides unprecedented insight and visibility across the storage network through critical monitoring and diagnostic capabilities. To transform this data into intelligence that storage teams can easily act upon, IBM Network Advisor visualizes health and performance data, along with details about out-of-policy conditions, in customizable dashboards and interactive SAN topology views.
Administrators can then quickly identify potential issues, abnormal behaviors, and trends at the device and fabric level. To further simplify network management and reduce costs, IBM Network Advisor provides simple wizards and right-click menu options to automate critical tasks, from configuration through troubleshooting and reporting. These powerful capabilities enable storage teams to proactively manage storage networks, maximize uptime, and optimize resources.
The following Fabric Vision technology features can be managed through IBM Network Advisor:
- Monitoring and Alerting Policy Suite (MAPS): Apply pre-built, customizable rules and policies to multiple ports, switches, or fabrics in a single click. Instantly visualize health and performance statistics of the SAN infrastructure in the dashboard, topology, and event views. Click through wizards to adjust configurations to ensure that availability is maintained with minimal expertise needed.
- Fabric Performance Impact (FPI) Monitoring: Set predefined thresholds in a single click from MAPS, and act on latency alerts highlighted in the dashboard or through email. Use customizable topology views to pinpoint visually which devices and hosts are impacted by a bottlenecked port (see Figure 2). Use the wizard and right-click menus to diagnose and troubleshoot before performance degrades.
- ClearLink Diagnostics: Configure ports to diagnostic mode, and view reports to validate optic and cable signal integrity before deployment.
- Configuration and Operational Monitoring Policy Automation Services Suite (COMPASS): Guard against drift from preferred configuration settings with COMPASS configuration and policy violation monitoring in IBM Network Advisor dashboards.
- Flow Vision: Automatically configure specific application flows directly from the network topology view to accelerate and simplify troubleshooting and maximize performance.
- IO Insight: Non-disruptively and non-intrusively gather input/output (IO) statistics from any device port, then apply this information within an intuitive, policy-based monitoring and alerting suite to configure thresholds and alarms. Integrated application-level and device-level IO latency and input/output operations per second (IOPS) monitoring provides the ability to establish baseline application performance profiles and detect degraded storage performance.

Rapid troubleshooting for increased availability
When network issues are identified, organizations must be able to diagnose and fix them quickly. IBM Network Advisor enables rapid troubleshooting with multiple dashboard views, highlighting out-of-range conditions, and providing drill-down menus for more details. As a result, administrators can correlate multiple data points across storage networks to make fast, informed decisions. IBM Network Advisor provides the following troubleshooting features:
- Live monitoring and point-in-time playback: Correlate real-time or historical device data across a choice of time scopes for advanced troubleshooting and performance management (see Figure 3).
- Network and time scope filters: Set a variety of network and time scope filters across dashboard widgets to quickly isolate, correlate, and troubleshoot error conditions.
- Event management: Receive Simple Network Management Protocol (SNMP) traps, syslog event messages, and customizable event alerts for monitoring and reporting on specific conditions
- Configuration change management: Select a default configuration, and track changes between the current and default state to isolate the root cause. If a failure occurs, the default configuration can be restored to minimize disruption during troubleshooting.
- Advanced Call Home: Automatically collect diagnostic information and send notifications for fast fault diagnosis, isolation, and remote support operations.
