1.2.3 Virtualization

Virtualization has become a widely preferred and suggested environment for IT

infrastructure by IT administrators:

● Server (Hardware) virtualization is a proven software technology that makes it

possible to run multiple operating systems on the same server at the same

time, sharing the available hardware resources. It simulates the available

hardware and deludes every operating system running on top of it to assume

that it is the unique holder of the resource. The details of the physical

environment are kept transparent from the operating system.

● Add-on options for hardware redundancy allow running the same virtual

machine on multiple physical servers. If a server fails for any reason, another

physical server running the same virtual machine can take its place. This

minimizes any interruption in service.

● Network virtualization create logical, virtual networks that are decoupled from

the underlying network hardware to ensure the network can better integrate

with and support increasingly virtual environments.

● Further virtualization types are desktop, application and service virtualization.

Desigo CC supports several server virtualization environments and their

redundancy options including transparent network virtualization. Terminal server

applications are not supported.

The following key components can be virtualized:

● Desigo CC Server

● Desigo CC Client

● Video Management Service

● Microsoft SQL Server

● Microsoft IIS Server

● Desigo CC FEP

options) please refer to section --- MISSING LINK ---

UL/ULC Deployments

Supported virtualization software in UL/ULC deployments is limited to VMware

VSphere. For UL/ULC compliance, all computers in the system (Server, Clients

and FEP) must be UL/ULC listed (Comark computers). Refer to section UL/ULC

Listed Machines [➙ 34] for UL/ULC computer information.
