Planning

Effective preparation and planning will make your installation and deployment go quickly and smoothly. Review the following preinstallation requirements to prepare for your installation.

Hardware and software requirements
The following information provides a consolidated view of the hardware and software requirements for your IBM® Cloud Infrastructure Center environment.
Planning for compute nodes and hypervisors
One management node can manage multiple compute nodes. The management node can be installed on either a z/VM guest Linux, or LPAR Linux.
Planning for TCPIP networks
In the IBM® Cloud Infrastructure Center, a network represents a set of Layer 2 or Layer 3 network specifications. For Layer 2 networks, it includes how your network is subdivided with VLANs, it also provides information about the subnet mask, gateway, and other characteristics. When you deploy a virtual machine in IBM® Cloud Infrastructure Center, you can choose one existing network to apply to the new virtual machine. Setting up networks beforehand reduces the amount of information that you need to input during each deployment and helps to ensure a successful deployment.
Planning for persistent storage and fabric zoning
Depending on whether it is managed by the underlayer hypervisor or by the storage provider, the storage that can be managed by the IBM® Cloud Infrastructure Center can be split into two catagories: Local Storage and Persistent Storage, refer to Terminology.
Planning for license
License tracking is enabled by default in IBM® Cloud Infrastructure Center. There are two types of license models:
Planning for security
Security is one of the chief considerations for any application including IBM® Cloud Infrastructure Center. Review the information here to understand your options and responsibilities in securing your installation.
Planning for multi-node cluster
IBM® Cloud Infrastructure Center supports three-node architecture, all the three management nodes must have the same configurations operating systems, CPU , memory.
