practice is to sample a maximum of one traffic flow for every 1000 (1:1000). Higher sampling rates degrade database performance and increase network traffic without adding any significant statistical information. Performance Management can support 600 inserts per second using a single disk (SSD) Drive. 1 insert = 1 monitored attribute. Expect better performance as you add more drives (and worse performance with slower drives). Event Management can support a sustained 1200 traps /sec using a single (SSD) drive. Expect better performance as you add more drives (and worse performance with slower drives). 4 Database memory settings increase as the number of database hits increases. At the 32GB level best practice is to use an SSD drive or fast disk array because of the large number of database actions possible. You can start and stop the client portion of the software without impacting the application server. Device monitoring stops when you stop the application server or turn off its host machine. The client can also be on a different machine than the application server. NOTE: See Starting Web Client on page 33 for more information about using web access to this software. 64-bit Since Dell OpenManage Network Manager has a web server, demands on 32-bit system resources are near their limits. A standalone 32-bit system with Application server, Web server, and database requires nearly all addressable memory, and is therefore not supported. Applications like Traffic Flow Analyzer and Performance Monitoring require even more memory. For these reasons, and for future scalability, do not install this software on 32-bit systems. Tablets, phones and iPads Dell OpenManage Network Manager detects mobile devices and pads. For smaller screens, the Navigation bar collapses to the left hand side and the page only displays a single column. Some limits apply: • Since touch devices do not support right click, the first time clicking on a row selects it. A repeat click launches a menu displaying the available actions. Click the one you want. • Charts that require flash may not work (some have HTML5 backup). • Visualize / Topology is unavailable. • Phones may limit views further Network Basics OpenManage Network Manager communicates over a network. In fact, the machine where you install it must be connected to a network for the application to start successfully. Firewalls, or even SNMP management programs using the same port on the same machine where this software is installed can interfere with communication with your equipment. 22 Sizing for Standalone Installations | Getting Started with Dell OpenManage Network Manager
