The present invention is directed towards systems and methods deploying a virtual server on a subset of devices in a cluster of devices. A first device of a cluster of devices intermediary between at least one client and at least one server, may identify a first virtual server to establish on one or more devices of the cluster. The first device may associate, to the identified virtual server, a group comprising a subset of devices in the cluster of devices. The cluster may establish the first virtual server on each device in the group responsive to associating the group to the first virtual server. Each virtual server on each device of the group may be assigned a same internet protocol address.

The present invention is directed towards systems and methods for load balancing by a multi-core device intermediary between clients and services. The device may establish sub-slots in each slot of the device's packet engines. The number of sub-slots may correspond to the packet engine count. Each slot may track a different number of active connections allocated to a service. The device may assign a first and second service to each packet engine in a first slot corresponding to no active connections. These services may be assigned to different sub-slots in adjacent packet engines. The device may update, responsive to allocation of a first active connection to the first service, the first service from a sub-slot in the first slot of a first packet engine, to a corresponding sub-slot in a second slot. The second slot may correspond to one active connection allocated to the first service.
