Installation Overview
You can deploy the Cisco Tetration (Secure Workload) M4 cluster as either a 39-rack unit (RU) large-form factor platform (C1-Tetration) for data centers with more than 5000 servers or as an 8-RU small-form factor platform (C1-Tetration-M) for data centers with fewer than 5000 servers. Additionally, you can deploy the large-form factor platform in either one or two racks depending upon your requirements.
The Cisco Tetration (Secure Workload) M4 cluster deployments are configured as follows:
-
