--> Riverbed Steelhead is implemented as Two Port Switch in Most situations.
--> One port of the Riverbed Steelhead is connected to LAN Switch and the other port is connected to WAN Router or Firewall.
--> Traffic can be configured for optimization or pass-through based on Port Number or Application or IP address.
--> Unoptimized or unaccelerated traffic is directly passed through via Riverbed with less delay.
--> An IP address is configured on the In Path Interface in addition to the management port for traffic optimization.
--> In Path IP address is usually configured in between LAN and WAN Ports.
--> The management access to the Riverbed is optional but highly recommended.
--> Fail to Wire NIC allow the traffic to pass through or block in case of riverbed power goes down or interface gets corrupted.
--> Following things need to be considered for the proper sizing of Riverbed Steelhead:
i) Number of Connections ( Assumption Per user 5 TCP Connections)
ii) WAN Bandwidth
iii) Disk Size for Backup & Replication
iv) Redundant Raid and Power Supplies
v) Number of Ports available on Steelhead Appliance
vi) High Availability Mode ( Active/Active or Active/Standby)
viii) Appliance Network Integration Mode ( In-Path or Out-of-Path or WCCP or PBR)
--> Riverbed Appliance can be integrated by using two methods:
i) In-Path: Riverbed Appliance is directly in the path of WAN Connection.
ii) Out-Of-Path: Riverbed Appliance is not directly in the path of WAN Connection ( Need PBR or WCCP Configuration to send the traffic to Riverbed)
