Host Hardware Requirements

Host Hardware Requirements

The IP Fabric platform runs on Intel Xeon Nehalem CPUs or later. The system runs in at least 4 parallel threads, but scheduling can handle operations even down to a single thread. IP Fabric uses less than 4GB of RAM when idle, and an additional 12GB of RAM is required for collected network information. The base installation requires 80GB of HDD space and an additional 50MB per device for the network.

Additional resources requirements

To make sure you have enough resources, please use the following formulas.

Data disk storage requires 1MB per device per each snapshot (example: 1350 devices, plan is to keep up to 100 snapshots => 135 GB data storage).

Memory requires 5MB of RAM per device per each loaded snapshot (example: 1200 devices, up to 100 snapshots but only 3 loaded at a time (1200 x 5 = 6000 x 3) => 18 GB RAM).

The recommended hardware resources may not allow running the most demanding graph traversal functions. These functions may require a sizable memory pool to complete successfully.
