Host network configuration

Before starting your StorageGRID deployment, determine which networks (Grid, Admin, Client) each node will use. You must ensure that all networks are extended to the appropriate physical or virtual hosts and that each host has sufficient bandwidth.

If you are using physical hosts to support grid nodes, extend all networks and subnets used by each node at the site to all physical hosts at that site. This strategy simplifies host configuration and enables future node migration.

Note: When configuring host network connections, you must also obtain an IP address for the physical host itself. You must also open the required ports to the host.
Note: A physical interface on the host can be used by the host itself and one or more nodes running on the host. Any IP addresses assigned to the host or nodes using this interface must be unique.

The following table provides the minimum bandwidth recommendations for each type of StorageGRID node and each type of network. You must provision each physical or virtual host with sufficient network bandwidth to meet the aggregate minimum bandwidth requirements for the total number and type of StorageGRID nodes you plan to run on that host.

Type of node Type of network
Grid Admin Client
Admin 10 Gbps 1 Gbps 1 Gbps
Gateway 10 Gbps 1 Gbps 10 Gbps
Storage 10 Gbps 1 Gbps 10 Gbps
Archive 10 Gbps 1 Gbps 10 Gbps
Note: This table does not include SAN bandwidth, which is required for access to shared storage. If you are using shared storage accessed over Ethernet (iSCSI or FCoE), you should provision separate physical interfaces on each host to provide sufficient SAN bandwidth. To avoid introducing a bottleneck, SAN bandwidth for a given host should roughly match aggregate Storage Node network bandwidth for all Storage Nodes running on that host.

Use the table to determine the minimum number of network interfaces to provision on each host, based on the number and type of StorageGRID nodes you plan to run on that host.

For example, suppose you want to use the following configuration:

In this scenario, you should provide a minimum of 11 + 20 + 10 = 41 Gbps of network bandwidth, which could be met by two 40 Gbps interfaces or five 10 Gbps interfaces, potentially aggregated into trunks and then shared by the three or more VLANs carrying the Grid, Admin, and Client subnets local to the physical data center containing the host.
