CitectSCADA Virtualized Environment

Hi Richard, I believe it's very common. We installed on VMWare ESXi for another customer with multiple sites. The only gotchas are in relation to poor virtual infrastructure management rather than the product itself. IT management of the server gives neither you nor the operational customer adequate visibility of the host's allocation and performance. IT people don't understand the criticality of OT systems, and think nothing of underspecifying a host machine and running too many VMs on a host with a large performance impact. Essentially the VM should act just like you've installed it on bare metal. If it just seems unresponsive and sluggish, then the host is probably overloaded.
Utilities like ESXTop can help to identify the exact bottlenecks if need be.
