4 Port GigE NIC
All Steelhead appliances except the 100 and 200 support an optional 4 port Gigabit Ethernet card. The 520, 1020, and 2020 support one 4-port card. Models 3020, 3520, 5520, and 6020 support up to three 4-port cards, for a total of 12 GigE interfaces. 4-port cards are essential for dual-router networks to ensure easy integration of a single Steelhead appliance into those more complex environments. The cards are available for an additional charge. Please contact your Riverbed sales representative for pricing and availability.

Automated Data Store Copying
This feature is useful in environments with two Steelhead appliances, one primary and one backup. With Automated Datastore Copying, the reference data and the references created with SDR are automatically copied from the primary to the backup Steelhead appliance. In the event of a software crash, or a hardware or power failure in the primary Steelhead appliance, the backup appliance can take over with a “warm” data store, and it can begin delivering optimized performance immediately.
Connection Forwarding / Asymmetric Routing Support
For networks with asymmetric routing on either side of the WAN (data center or branch office), RiOS includes mechanisms for connection forwarding. All Steelhead appliances support asymmetric routing which enables simple integration into the most complex enterprise networks.
