Offices of just a few users often need WAN optimization, but they lack the budget for specialized appliances, or even a commercial server. When budgets are that tight we’ve been able to develop an alternative solution: run Silver Peak WAN optimization on a user’s PC. The admin, in our case, never noticed that the PC was doubling as a WANOp platform, and the users got all the performance bang you’d expect.
Yes, the user has to learn not to turn off the computer, but since when is that a problem? Usually, getting users to reboot their systems is our challenge. In practical terms, a piece of tape or Post-It was about all we needed to keep the system running.
Anyway, here’s how we did it with a VirtualBox appliance. A similar approach would work with other desktop environments, such as VMware Workstation. Keep in mind, a separate appliance must be configured to run the user’s desktop and applications.
First you have to make sure that minimum requirements are satisfied to run VirtualBox. i5 or similar processor, 4GB of RAM, 100GB free space, x64 operating system and Intel VT or AMD-V should be enabled in BIOS.
Please consider checking the VX requirements from the “Velocity Replication Accelerator (VRX) Host System Requirements” document which can be found on the Silver Peak user documentation page.
Without adding a virtual hard drive press Create
Go to Properties > System > Storage and create two disks:
For the second disk (Network Memory) follow the same steps that you did to create the first disk. Remember that Network Memory must be at least 70 GB (Max 2TB)
Mount the Silver Peak ISO to CD-Rom. The ISO may be downloaded from the Silver Peak Marketplace (please note that you have to select KVM, Hyper-V, or Citrix to be able to download the ISO file).
Select properties > Network > Adapter 1
If you have more than one network in your computer you have to configure the correct network to bridge. Select VirtualBox Bridged Networking Driver.
If you have DHCP it should get the IP automatically, otherwise you may assign an IP address manually.
[vx name] # config t [ENTER]
[vx name] (config) # interface mgmt0 shutdown [ENTER]
[vx name] (config) # no interface mgmt0 dhcp [ENTER]
[vx name] (config) # interface mgmt0 ip address 10.10.10.10 / 24 [ENTER]
[vx name] (config) # no interface mgmt0 shutdown [ENTER]
[vx name] (config) # show interfaces mgmt0 [ENTER]
To configure the default gateway, enter the following command sequence:
[vx name] (config) # ip default-gateway 10.0.41.193 [ENTER]
[vx name] (config) # show ip default-gateway [ENTER]
File protocol: SFTP
IP: The IP Address of the Silver Peak Management Interface
User: admin (Default)
Pass: admin (Default)
Save the file.
You have to follow the same order in your VirtualBox as Vm0, Vm1 etc.
VmName= [this must be exactly the same name as your VirtualBox virtual machine name]
ShutdownMethod=[Choose between ‘savestate’ and ‘acpipowerbutton’. This is the action that will be taken in case the computer shuts down. Recommended: acpipowerbutton.]
AutoStart=[any VMs with ‘yes’ will be autostarted]
After editing this file you may restart your computer to test the actions. If the tests succeed, you are ready to configure your tunnel and route policy and to start optimization.
