Note

  • *For a larger dataset per day, run Stats on all the servers.

  • ** Along with the SAIE, the Approute statistics are also considered in the recommendations.

Note

The number of days the data can be stored in Cisco SD-WAN Manager, depends on per-day processing volume of the device nodes. To store the data for a longer time or to accommodate the increase in per-day processing volume, use the following formulas to calculate the required Cisco SD-WAN Manager disk size:

Formula to calculate the Cisco SD-WAN Manager disk size required for single node deployment: (Data per day × number of days) + 500 GB buffer . For example, if the data per day is 100 Gigabytes and the number of days the data must be stored is 10, then the required Cisco SD-WAN Manager disk size is 1.5 Terabytes.

Formula to calculate the Cisco SD-WAN Manager disk size required for cluster deployment: (Data per day × number of days × 3) + 500 GB buffer . For example, if the data per day is 100 Gigabytes, the number of days the data must be stored is 10, then the required Cisco SD-WAN Manager disk size is 3.5 Terabytes.
