Required Server Resources

Apstra server VM resource requirements are based on the size of the network (blueprint), the scaling of off-box agents and the use of Intent Based Analytics (IBA). If one VM is insufficient for your needs, cluster several VMs to increase resources.

CAUTION:

Although Apstra server VMs might run with fewer resources than recommended below, depending on the size of the network, the CPU and RAM allocations may be insufficient. The system could encounter errors or a critical "segmentation fault" (core dump). If this happens, delete the VM and redeploy it with additional resources.
Table 1: Recommended VM Resources
Resource Recommendation
Memory 64 GB RAM + 300 MB per installed off-box agent*
CPU 8 vCPU
Disk 80 GB
Network 1 network adapter, initially configured with DHCP

* Off-box agent container memory usage is dependent on the number of IBA collectors enabled. You can add worker nodes to scale off-box agent capacity. We recommend using the Apstra Cluster feature in the GUI to monitor usage as shown below.
