With the VX machines, the clients often confuse the hardware itself with the services and resources. VMs are configured according to resources - memory, hard disk capacity, and network. These resources, including memory and processor, are actually shared on the VX Series. 

So, if the server's processor is underpowered or unreliable for the VMs, many of the VMs will encounter issues. Ideally, the physical server configuration should align more closely with the needs of the virtual servers.

The drawback is that the hardware resources (CPU, memory, storage) are shared among all the VMs running on the VX Series. If the server's processor is underpowered for the VMs, many of the VMs might have performance issues. An improvement could be to have more granular control over resource allocation to VMs.

Lenovo ThinkAgile VX Series needs to improve its stability. Its resolution should be faster. 

Support could be better.

The user management could be a bit better. It's something they could improve upon in future releases.
