Although CCS recommends dedicated hardware for optimal performance, certain components of the application can be run successfully within virtualized environments. For ease of management, you can use virtualized servers to host CCS servers. A virtualized server can host any CCS server role. Certain server roles lend themselves naturally to a virtualized host. When you create a virtualized server to host CCS components, ensure that the computer that hosts the virtual servers meets certain recommendations. You should also ensure that the individual virtual servers meet the recommendations appropriate to the role.
A virtualized server can successfully host the following server roles:
Application Server in a very small deployment (Less than 1000 assets in a system)
CCS Manager Load Balancer
CCS Manager Evaluator
CCS Manager Reporter
A virtualized server should generally not host the following server roles:
CCS Manager Collector
CCS does not recommend running Microsoft SQL Server in a virtualized environment; the memory and I/O demands of a SQL database are such that the physical to virtual translation penalty for each transaction accumulate to a substantial increase in response times. You can use a virtualized server to host any role, but for highest performance you should use a physical server for the following server roles:
CCS Manager Collector
When you create a virtual machine to host a CCS Manager for agent-less data collection, the virtual machine must have access to at least 8 GB of memory. It should also have 16 logical processors. For agent-based raw-data or message based data collection, CCS Manager should have at least 4GB of memory and 8 logical processors. Also for the Virtual machines used for CCS components, user should assign reserved memory and CPU. When you create the virtual machine, you should immediately install the VMware Tools. The network adapter type for the virtual machine should be set to Flexible.
The virtual server host has the following specifications:
8-way 3.0 GHz or faster processors
32 GB or more memory
600 GB or greater, 15000 RPM hard disk
Gigabit network interface
As permanent storage resources are typically shared across VMs, there is a much greater potential to encounter disk and/or I/O contention issues as compared to a physical server. Dedicated spindles or a SAN are recommended to lessen the likelihood of this contention.
