Several KCS server package 7.86.00 components were installed on the host, most prominently TCOSS
with 60 fax channels, connected with two LS1V2, each with 30 fax channels.
In such a configuration with 60 fax channels running in parallel, test ran successfully with an average CPU
usage of the virtual machine at around 13 percent.
Similar configuration with 30 FoIP channels was tested successfully as well.
During tests it was observed that extensive disk operations on the host (e.g., copying large volume of data)
may result in a dramatic performance decrease on the guest.
5.7 Restrictions
From VMware only ESX Server is supported. VMware Workstation, VMware Player, and VMware Server
(formerly called VMware GSX Server) are NOT supported.
Hyper-V is only supported with Windows Server 2008 R2 as host operating system.
A Tandem system can only be supported if the primary server is on another physical host than the
secondary server.
With TC/Archive, TC/Juke or a DVD/CD writer are not supported. Only network storage is supported.
If there are timeouts or low throughputs, increase the allocated resources on the virtual machine or use
dedicated hardware!

Maximum of 30 FoIP Fax channels are supported per TCOSS (single or tandem) server
Not more than 10 instances of IPPrinter are supported, although more instances can be installed.
LSD cannot be supported, as no serial interface is available on virtual machines.
TCOSS must run on a single virtual machine (max. 10 instances)
TC/Report is only supported if the SQL Server is not running on the same machine. Running TC/Report
on MSDE or SQL Express is not supported.
Productive TC/Web installations on virtual machines are not supported. TC/Web test & development

TC/MA is not supported.
5.8 Hints
5.8.1 MAC Address Locking
If you want to run the KCS systems on VMware clusters, you have to lock the MAC address on the TCOSS
server.
If this is not done, there will be licensing problems when TCOSS boots up on another cluster server.
