UL/ULC Compliance
For UL/ULC compliance, the use of virtual machines is limited to VMware
VSphere and the all computers in the system (Server, Clients and FEP) must be
UL/ULC listed (Comark computers). Refer to section Hardware Category
Definitions [➙ 31] for UL/ULC computer information.
Refer to the virtualization software specifications to indicate the hardware
requirements for the Virtual Machine hosts.
Ensure you have a read/write speed to storage of >=150 MBps
In case you cannot provide this processor speed or dedicated vCPUs are not
available during runtime due to overprovisioning, degraded performance can be
expected.
In case multiple virtualized clients share the same network resources, application
specific limitations might apply. Example: It is not possible to transport a large
amount of video streams over a single network connection.
For system being part of a distributed topology, please carefully read Distributed
System Configurations [➙ 37].
