Abstract

Systems and methods described herein provide a high availability DHCP server capable of serving multiple tenants in a data center. The DHCP server may use a different logical DHCP server instance for each tenant, and may be implemented as one process without the use of namespaces. A DHCP server is executed on a gateway virtual machine (VM) that is capable of hosting a plurality of logical DHCP servers. For each tenant in a data center, a logical network and a corresponding logical DHCP server instance are implemented. The DHCP server may service requests for DHCP services from VMs via their physical host by determining the tenant that the VM originates from and leasing a DHCP resource from that tenant's corresponding logical DHCP server instance.
