| --------------------------------- | -------- | -------- | ------------------------------------------------------------------ |
| vCPU (per VM)                     | 32       | 32       | Number of available vCPUs per VM.                                  |
| RAM (per VM)                      | 128 GB   | 128 GB   | Maximum RAM per VM (min. 0.5 GB).                                  |
| Network Cards (per VM)            | 10       | 10       | Maximum number of network adapters per VM.                         |
| Edge Gateway (per organization)   | N/A      | 5        | Maximum number of Edge Gateways per organization.                  |
| Public IPs (per vDC)              | N/A      | 2        | Number of available public IPs per vDC.                            |
| Snapshots (per VM)                | 1        | 1        | Maximum of 1 snapshot per VM.                                      |
| VMs (per vApp)                    | 128      | 128      | Maximum number of VMs allowed per vApp.                            |
| VMs (per organization)            | 2000     | 4000     | Maximum number of VMs per organization.                            |
| vApps (per organization)          | 10,000   | 10,000   | Maximum number of vApps per organization.                          |
| Segments (per organization)       | 40       | 40       | Maximum number of segments per organization.                       |
| vRack Segments (per organization) | 7        | 7        | Maximum number of vRack segments (1 public + 1 trunk + 5 private). |

**Warning:**

**NOTE**: When creating a snapshot that includes the VM's memory, storage usage can quickly add up. For example, if you have 1 VM with 1 GB of RAM and a 10 GB disk, and you create a snapshot that includes memory, your storage usage will be: 10 GB (disk) + 1 GB (VM swap) + up to 10 GB (disk snapshot) + 1 GB (memory snapshot) = **22 GB total**.
