About BIG-IP WOM Virtual Edition

BIG-IP® WOM® Virtual Edition (VE) is a version of the BIG-IP WOM system that runs as a virtual machine (VM) in specifically supported hypervisors. BIG-IP VE emulates a hardware-based BIG-IP WOM system running a VE-compatible version of BIG-IP® software. Hypervisor compatibility, specifications, and instructions for setting up VE for any BIG-IP system are documented elsewhere. An additional consideration for BIG-IP WOM VE is the extra disk option, with which you can allocate datastor for symmetric deduplication to the disk.

Hypervisor guest definition

The VMware virtual machine guest environment for the BIG-IP® WOM® VE, at minimum, must include the following:

  • 2 x virtual CPUs (reserve 2 GHz)
  • 4 GB RAM with a 2-core CPU
  • 8 GB RAM with a 4-core CPU
  • 2 GB RAM with 2-core CPU (upgrade path from version 10.2.x)
  • 1 x virtual Flexible (PCnet32 LANCE) network adapter (for management)
  • 3 x virtual VMXNET3 network adapters
  • 1 x 100 GB SCSI disk, by default
  • 1 x up to 500 GB SCSI disk, as an extra disk option

Licensing considerations

The BIG-IP® WOM® VE product license determines the maximum allowed throughput rate. Three license options are available for BIG-IP WOM VE:

WOM VE Lab License
Aggregate throughput limited to 10 Mbps on the LAN side
WOM VE Production License: 200M or 1G
Aggregate throughput limited to 200 Mbps or 1 Gbps on the LAN side

To view the rate limit, you can display the BIG-IP VE licensing page within the BIG-IP Configuration utility. Lab editions have no guarantee of throughput rate and are not supported for production environments.

Configuration considerations

You configure BIG-IP® WOM® VE just as you would any BIG-IP VE system. If you select one of the extra disk options during configuration, you can then allocate the additional disk space for symmetric deduplication datastor. If more disk space is required when using VE, you can size the extra disk from the default of 50GB to 255GB.

If you configure BIG-IP WOM with an extra disk, you must then delete the datastor volume that is on the primary disk, and assign it to the extra disk.

Provisioning extra VE disk for datastor

Before beginning this procedure, you must have licensed and configured BIG-IP® WOM® Virtual Edition (VE).
If you selected one of the extra disk options when you configured BIG-IP WOM VE, you must manually allocate the disk space to the datastor service, after you delete the datastor application volume from the primary disk. Datastor cannot span the primary disk and the extra disk.
  1. On the Main tab, click System > Resource Provisioning . You must de-provision WOM before you can delete the datastor allocation from the primary disk.
  2. In the Resource Provisioning (Licensed Modules) area. from the WAN Optimization (WOM) list, select None (Disabled).
  3. Click Update.
  4. Click OK to proceed. The BIG-IP system restarts without WOM in the configuration, which may take a minute or so.
  5. Click Continue.
  6. On the Main tab under System, click Disk Management.
  7. In the Logical View area, click HD1. The General Properties screen opens for the primary disk.
  8. In the Contained Application Volumes area, select the check box for Datastor, and click Delete.
  9. On the Disk Management screen, click HD2. The General Properties screen opens for the extra disk.
  10. In the General Properties area, for the Mode setting, select Datastor.
  11. Click Update.
  12. On the Main tab under System, click Resource Provisioning.
  13. In the Resource Provisioning (Licensed Modules) area, from the WAN Optimization (WOM) list, select Nominal.
  14. Click Update.
  15. Click OK to proceed. The BIG-IP system restarts with WOM in the configuration, which may take a minute or so.
  16. Click Continue.
The datastor is now allocated to the extra disk. You can verify the result by checking the Disk Management screen.
