Outlines the virtual machine, storage, network, IP address, Crosswork Data Gateway, and topology requirements for preparing supported Crosswork Network Controller installations.
This chapter lists the requirements that apply before you install Cisco Crosswork Network Controller and its components. It covers deployment resources, storage performance, network ports, IP addresses, and supported topology models.
Installation requirements overview
Outlines the general and platform-specific prerequisites for installing Crosswork components, including VM, port, application, and deployment requirements for supported environments.
VM requirements
Summarizes the per-VM resources required for the Crosswork cluster and Crosswork Data Gateway, and links to detailed host and gateway specifications.
Validate storage performance and review diagnostics
Use this topic for VMware and KVM deployments to validate storage performance before installation, review diagnostic results during installation, and understand the risk of bypassing failed diagnostic checks.
Crosswork network ports and communication details
Lists ports and communication details for internal cluster traffic, northbound and southbound services, Crosswork Data Gateway, single VM deployments, and geo redundancy.
IP address restrictions
Lists protected IPv4 and IPv6 subnets and describes network ranges that cannot be used for other devices or purposes in a Crosswork cluster.
Supported network topology models
Describes supported Crosswork topology models and lists NIC deployment modes for Crosswork VMs and integrated components in supported data center environments, including two- and three-NIC models.
