Front-end network usage

The [hcp_system] network is always used for:

Access to the HCP System Management Console

Access to the Tenant Management Console for the default tenant

Access to the HCP management API using a system-level URL

Syslog functions at the system and tenant levels

SNMP functions at the system and tenant levels

Access to the default namespace using the namespace access protocols

Access to the HCP metadata query API using a system-level URL

Access to the HCP Search Console using a system-level URL

Access to the default namespace using HCP Data Migrator

Communication between HCP and Active Directory for configuration and for user authentication at the system and tenant levels

Communication between HCP and RADIUS servers for user authentication at the system and tenant levels

For SAIN systems, communication between HCP and the storage arrays

Communication between HCP and any external storage components configured for the system

Communication between HCP and Hitachi Tiered Storage Manager

Communication between HCP and Hitachi Device Manager (HDvM)

Communication between HCP and Hitachi Remote Ops®

Access to the HCP system through interfaces reserved for authorized service providers

You can choose to use [hcp_system] or any user-defined network for the following purposes:

Management of a given HCP tenant, including:

oAccess to the Tenant Management Console for the tenant

oAccess to the HCP management API using a URL for the tenant

You select the network for this purpose when you create or modify the tenant.

Access to the namespaces owned by a given HCP tenant, including access through:

oNamespace access protocols

oNamespace Browser

oHCP metadata query API using a URL for the tenant

oHCP Search Console using a URL for the tenant

oHCP Data Migrator (HCP-DM)

You select the network for this purpose when you create or modify the tenant.

Communication with other HCP systems in a replication topology.

You can use the same network for multiple purposes. If you don’t choose a network for a purpose, HCP uses [hcp_system] by default.

When you select a network for a given purpose, you need to ensure that your networking infrastructure is configured to allow client requests for that purpose to be routed to that network. HCP responds to each client request on the same network as the one on which the request arrived. Therefore, clients do not need to be on the same subnet as the network they are using to access the system, but they do need to be configured to use at least one IPv4 or IPv6 address that is routable from that network.
