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) |

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.

When you create your Swift cluster, you can specify the number and disk size of storage and proxy nodes in it. You can also add nodes after the cluster is created.
If you need to change the number of vCPUs or amount of vRAM used for proxy or storage nodes, modify the following parameters in the /opt/vmware/vio/etc/omjs.properties file and restart the OpenStack Management Server service.
oms.vmsize.cpu.swift_proxy oms.vmsize.cpu.swift_storage oms.vmsize.memory.swift_proxy oms.vmsize.memory.swift_storage
The size of the root disk of each node is fixed at 20 GB.
