This section provides a high-level overview of setting up a storage cluster in a network.
...
If client workstations are configured with 100 Mbps network interface controllers (NICs) or cannot effectively use more than 100 Mbps of bandwidth, connecting these systems to 1000 Mbps Ethernet switches may not be cost-effective. In this case, consider connecting these workstations to a separate Ethernet switch that supports the slower bandwidth speed.
When selecting Ethernet switching hardware, remember that many Many client workstations are configured with 100 Mbps NICs , and it may not be cost-effective to connect these workstations to 1000 Mbps ports. Additionally, the The operating systems and applications running on these workstations may be unable to use more than 100 Mbps of bandwidth effectively.

To present a cluster as a read-only device to external clients, block the POST and DELETE requests to prevent updates to the cluster.
To prevent client access to the Node Status window in the Swarm Admin Console, configure the firewall to deny "GET /" requests to the cluster nodes.
To prevent unauthorized access to the Swarm Admin Console, block Internet access to the Swarm Admin Console port (default TCP port 90) and the SNMP port (UDP port 161). Wide area networks (WANs) may require additional restrictions to prevent access to specific administrative networks or workstations.
To minimize the client impact of hardware failures, deploy devices in redundant pairs when adding security devices such as firewalls into the network architecture.
