Some configurations however are not compatible with the Hosted Private Cloud solution. **This guide explains Hosted Private Cloud compatibility with the OVHcloud vRack.** ## Requirements - Being an administrative contact of your [Hosted Private Cloud infrastructure](https://www.ovhcloud.com/en-gb/enterprise/products/hosted-private-cloud/) to receive login credentials - A user account with access to vSphere (created in the OVHcloud Control Panel) ## Technical background In the Hosted Private Cloud product, there are two types of vRack: - "VM Network" is a vRack on a **single VLAN**, which is the native VLAN of the Hosted Private Cloud public VLAN. This VLAN is used in Hosted Private Cloud to route Public IPs. It is listed in the vSphere inventory as a _PortGroup_, in the "Network" category, called "VM Network". This vRack is then attached to the virtual switch, which is fully managed by OVHcloud. - "Datacenter vRack", or "vRack vDC", or "dvs-vrack", is the vRack that allows you to have **4000 VLANs**. This vRack is attached to the virtual switch managed by the customer, with its own dedicated network cards. It is important to note that some commercial ranges, such as AMD host-based ranges, do not have a virtual switch managed by the customer. Only the vRack type "VM Network" is available.
