AWS Storage Gateway User Guide
Performing Tasks on the VM Local Console (File Gateway)
If your gateway is already activated, you must shut it down and restart it from the AWS Storage
Gateway Management Console. After the gateway restarts, you must test network connectivity to
the internet. For information about how to test network connectivity, see
Connection to the Internet (p. 235)
Configuring Your Gateway for Multiple NICs
If you configure your gateway to use multiple network adapters (NICs), it can be accessed by more than
one IP address. You might want to do this in the following situations:
•
Maximizing throughput
– You might want to maximize throughput to a gateway when network
adapters are a bottleneck.
•
Application separation
– You might need to separate how your applications write to a gateway's
volumes. For example, you might choose to have a critical storage application exclusively use one
particular adapter defined for your gateway.
•
Network constraints
– Your application environment might require that you keep your iSCSI targets
and the initiators that connect to them in an isolated network. This network is different from the
network by which the gateway communicates with AWS.
In a typical multiple-adapter use case, one adapter is configured as the route by which the gateway
communicates with AWS (that is, as the default gateway). Except for this one adapter, initiators must
be in the same subnet as the adapter that contains the iSCSI targets to which they connect. Otherwise,
communication with the intended targets might not be possible. If a target is configured on the same
adapter that is used for communication with AWS, then iSCSI traffic for that target and AWS traffic flows
through the same adapter.
In some cases, you might configure one adapter to connect to the Storage Gateway console and then
add a second adapter. In such a case, Storage Gateway automatically configures the route table to use
the second adapter as the preferred route. For instructions on how to configure multiple adapters, see
the following sections:
