Dedicated CMS appliance vs VM

[nokelbokel]

Just started a job at a company and we are preparing to upgrade our old equipment that is EOL. We are currently running two CMS 1000s and the recommendation is to upgrade to the CMS Small M7s which are essentially preconfigured c220 m4s. The CMS1000 is running ESXI 6.0 and no one ever upgraded it or pulled it into VCenter so I currently cannot view any CPU usage or other statistics. This should be fixed as we are meeting with Broadcom to get this upgraded to a more current version which can be pulled into the current infrastructure.

If you're already planning to upgrade the CMS platform and your infrastructure supports virtualization, moving to a VM-based CMS deployment on supported UCS hardware is often more flexible and scalable than using a dedicated appliance like the CMS M7. However, if you need a plug-and-play setup with validated hardware, the appliance approach is simpler. Ultimately, the choice depends on your operational model—VMs offer agility and integration, while appliances offer simplicity and pre-validation. Either way, upgrading ESXi and integrating with vCenter is a good first step.
