Out-of-band (WCCP) mode (VMware ESXi)

This configuration can be done either at a branch office with virtual infrastructure, or in the data center where the application and local user traffic accessing the WANWide Area Network is redirected to the Exinda Virtual Appliance for diagnostics, shaping, and acceleration.

Scenario

• Branch users access local services (print, DHCPDynamic Host Configuration Protocol, Active Directory) that are virtualized.
• One physical NIC interface is dedicated for management of the virtual machines and hypervisor.
• One physical NIC interface is configured on the hypervisor for LANLocal area network access, and has a routed connection to the WAN router.
• One physical NIC interface is configured and mapped to the AUX port on the Exinda Virtual Appliance.
• OPTIONAL: It is possible to configure and map all data traffic through a single NIC interface on the hypervisor; however, for performance reasons it is recommended to segment the un-optimized traffic from the optimized traffic.
• User access from the branch office to the Data Center applications has two paths:

• Path one is directly to the WAN router, with no traffic shaping or acceleration.
• Path two is through the re-directed path invoked by the router (using WCCP) to the Exinda virtual appliance. The traffic is optimized and accelerated.

• Traffic on the Data Center side has the same path as the branch side. Traffic that is selected to be optimized and accelerated is redirected to the Exinda Virtual Appliance through WCCP on the WAN router.
• The Exinda provides Diagnostics, Shaping, and Acceleration for only redirected traffic in this configuration

Use Case

Use-case for Out-of-band (WCCP) mode (VMware ESXi)

In this use case:

• The virtual LAN with application servers (APP1 W2003 or 8 and APP2) are configured in the ESXi hypervisor on SW1 and mapped to NIC1. They have a direct path the WAN router.
• The physical server is a re-purposed Dell Server and has the following physical/logical interface mappings for illustration purposes only (you are encouraged to select your own server):

ESXi Ethernet Ports	NIC0	NIC1	NIC2
Exinda Ethernet Ports	ETH0	ETH1	ETH2
ESXi Virtual Switches	SW0	SW1	SW2

• The host has three NICs; NIC 0 is dedicated for management of the system.
• NIC 1 is dedicated to all virtual application workloads hosted on the ESXi.
• All virtual application workloads are configured in the ESXi to SW1.
• The Exinda Virtual Appliance is configured on SW2 virtual switch and is mapped to the NIC2 interface.
• The NIC2 interface has a direct connection to the WAN router, and is configured for WCCP GRE layer 3 mode between the router and the Exinda Virtual Appliance.
• VMware version = 5.5 and 6.0
• Exinda Virtual Appliance firmware version = 7.4.9
• The data path for virtualized applications configured on SW1 takes two paths:

• Path one – un-optimized and un-accelerated traffic is forwarded directly to the WAN router through NIC1.
• Path two – traffic to be optimized (traffic shaped) and accelerated traffic is forwarded to the router for redirection through WCCP to the Exinda Virtual Appliance through NIC2/SW2 on the AUX port of the Exinda Virtual Appliance.

• (Optional) It is possible to configure and map all data traffic on SW1 and SW2 to the NIC1 interface; however, for performance reasons it is recommended to segment the optimized traffic on its own NIC and virtual switch for performance reasons, and in the event of failure of the Exinda Virtual Appliance.
