Number of vNICs per VM | unlimited |
Number of IP addresses per VM | 256*** |
Size of guest virtual disk | 2 TB (MBR disks) 9.4 TB (GPT disks) |
Maximum number of VMs running on the cluster node | limited by the resources of the cluster node |
Maximum number of vCPUs enabled on the cluster node | limited by the resources of the cluster node |

Number of VMs running and protected in a high availability cluster | 2048 pcs |
Recommended maximum number of VMs per platform (if this limit is exceeded, performance may be degraded) | 25000 pcs |
Maximum number of VMs per platform (the functionality of a platform with this number of VMs has been tested, but performance may be significantly degraded) | 65535 pcs |
*maximum number of nodes the configuration has been tested with
**tested on a configuration with 350 nodes
***adding more IP-addresses is possible, but the performance of the VM with this configuration is not guaranteed
