details). The additional space required depends on the W-ClearPass virtual appliance version.
Processing and Memory Requirements
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 IOPs (I/O operations per second) throughput as
detailed below.
W-ClearPass Server I/O Rate
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.
Before Starting the W-ClearPass Installation
Before starting the installation and configuration procedures for the virtual appliance, determine the following
information for the W-ClearPass server on your network, note the corresponding values for the parameters
listed in Table 7, and keep it for your records:
