The specific hardware required to run VMware Integrated OpenStack depends on the type of deployment and networking that you select.
HA Deployments
Three ESXi hosts are required to deploy the following virtual machines:
| Component | Virtual Machines | vCPUs | vRAM (GB) | Disk Space (GB) |
|---|---|---|---|---|
| OpenStack Management Server |
1 |
VDS: 2 (2 per VM) NSX: 4 (4 per VM) |
4 (4 per VM) |
25 (25 per VM) |

An additional compute driver virtual machine with the same specifications is created for each compute cluster that you add to the deployment.
Compact Deployments
One ESXi host is required to deploy the following virtual machines:
| Component | Virtual Machines | vCPUs | vRAM (GB) | Disk Space (GB) |
|---|---|---|---|---|
| OpenStack Management Server |

VDS Networking
For HA deployments with VDS networking, the following resources are also required.
| Component | Virtual Machines | vCPUs | vRAM (GB) | Disk Space (GB) |
|---|---|---|---|---|
| DHCP |
2 |
8 (4 per VM) |
32 (16 per VM) |
40 (20 per VM) |
For compact and tiny deployments with VDS networking, the DHCP service runs on the controller node and does not require independent virtual machines.

Additional Components
If you want to use Ceilometer, the following resources are also required.
| Component | Virtual Machines | vCPUs | vRAM (GB) | Disk Space (GB) |
|---|---|---|---|---|
