2 | Installing or Upgrading to 6.6 on a Virtual Machine| Tech Note
Virtual appliance recommendations are adjusted to align with the requirements for W-ClearPass hardware
appliances. If you do not have the VA resources to support a full workload, then you should consider ordering
the W-ClearPass Policy Manager hardware appliance.
Be sure that your system meets the recommended specifications required for the Policy Manager Virtual
Appliance. The W-ClearPass VMware ships with a 20 GB hard disk volume. This must be supplemented with
additional storage/hard disk through VMware settings by adding a new hard disk. The additional space
required depends on the W-ClearPass virtual appliance version.
To ensure scalability, dedicate or reserve the processing and memory to the W-ClearPass VM instance. You
must also ensure that the disk subsystem can maintain the IOP’s throughput as detailed below. Most
virtualized environments use a shared disk subsystem assuming that each application will have bursts of I/O
without a sustained high I/O throughput. W-ClearPass Policy Manager requires a continuous sustained high
data I/O rate.
If you do not add a new hard disk to the VM before it is powered on, it will continue to restart with kernel panics.
An ESXi version can be morphed to a larger version by using the morph-vm command. For more information,
see the Command Line Interface > System Commands section in the W-ClearPass Policy Manager 6.6 User
Guide.
