Networking requirements for ESS
This topic describes the networking requirements for installing ESS.
Networking requirements
- Service network
This network connects the flexible service processor (FSP) on the management server and I/O server nodes as shown in blue in Figure 1.
- Management and provisioning network
This network connects the management server to the I/O server nodes (and HMCs, if available) as shown in yellow in in Figure 1. The management server runs DHCP on the management and provisioning network. If a management server is not included in the solution order, a customer-supplied management server is used.
- Clustering network
This high-speed network is used for clustering and client node access. It can be a 10 Gigabit Ethernet (GbE), 40 GbE, or InfiniBand network. It might not be included in the solution order.
- External and campus management network
This public network is used for external and campus management of the management server, the HMC (if available), or both.
Figure 1, Network Topology, is a high-level logical view of the management and provisioning network and the service network for an ESS building block.
The management and provisioning network and the service network must run as two non-overlapping networks implemented as two separate physical networks or two separate virtual local-area networks (VLANs).
The HMC, the management server, and the switches (1 GbE switches and high-speed switches) might not be included in a solution order in which an existing or customer-supplied HMC or management server is used. Perform any advance planning tasks that might be needed to access and use these solution components.
