When defining a network environment, the physical network device configuration should be designed considering the virtual systems that will actually be provided to the users.
Resource Orchestrator Networks
Resource Orchestrator networks are categorized into the following three types:
Network for the Admin LAN
The admin LAN is the network used by admin servers to communicate with agents on managed servers and other managed devices (network and storage devices) for performing installation, operation, and maintenance.
Network for the Public LAN
The public LAN is the network used by managed servers and managed network devices (firewalls, server load balancers, L2 switches, and Ethernet Fabric switches) to provide services over internal or external networks (such as intranets or the Internet).
Network for the iSCSI LAN
The iSCSI LAN is the network designed for communication between managed servers and storage devices.
For keeping operations secure, it is recommended to physically configure each network separately.
The maximum value of the subnet mask of the network that Resource Orchestrator supports is 255.255.255.255 (32-bit mask). The minimum value is 255.255.0.0 (16-bit mask). However, 255.255.255.254 is not supported.
Information
The admin LAN and iSCSI LAN are the networks that only infrastructure administrators need to be concerned about in normal operation.
