Determining Port Adapter and System Memory Requirements Chapter 2 Memory Requirements Determining Port Adapter and System Memory Requirements Table 2-1 Initial Memory Requirement Guidelines Question What determines the amount of SDRAM or DRAM memory required? Where can I find Cisco IOS memory requirements? Answer The DRAM or SDRAM required by a Cisco 7200 series router to support a combination of installed port adapter types and a Cisco IOS software subset image is influenced by such variables as the features in the software you plan to use and the size of your network. Cisco IOS memory requirements are listed in the Cisco IOS Release Notes. The SDRAM column provides processor memory information. Flash memory recommendations are also included. For Cisco IOS Release Notes, see the documentation page for Cisco IOS Software Configuration. If you are a registered user on Cisco.com, you can access the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl to get memory requirements. Sample Configuration Showing Processor Memory Required Use the example in Table 2-2 to familiarize yourself with the criteria for determining processor memory required for your configuration. Then use the worksheet in Table 2-3 to determine the processor memory required for your configuration. Cisco 7200 Series Port Adapter Hardware Configuration Guidelines 2-2 OL-3875-11
