Apstra Flow Scaling Considerations

The Apstra Flow virtual images are available in three sizing options, plus an additional option for creating custom extra-large deployments. Table 1 describes the available sizing options and memory requirements.

Table 1: Apstra Flow Scaling Considerations
*Image Size	Required Memory Size	Number of Supported Devices
Small Up to 5,000 FPS	8 vCPU, 32 GB memory, 4 TB disk	Typically, up to 25 devices at an average of 200 FPS per device.
Medium Up to 10,000 FPS	16 vCPU, 64 GB memory, 4 TB disk	Typically, up to 50 devices at an average of 200 FPS per device
Large Up to 15,000 FPS	24 vCPU, 64 GB memory, 4 TB disk	Typically, up to 75 devices at an average of 200 FPS per device
X-Large (custom)	N/A	Greater than 15,000 FPS. If you have an extra-large or custom deployment, we recommend that you create a multinode cluster. See Create an OpenSearch Multinode Cluster (Optional).

_{*Image size is calculated at an average number of flows per second (FPS) that the
collector receives.}
