Abstract: A method and a system for implanting a handshake between a source cluster having files replicated to a destination cluster, the system comprising: a source cluster having a plurality of nodes and replication manager; and a destination cluster having a plurality of nodes, a replication manager and single port manager which run on each node of the destination cluster, wherein the replication managers of the source and destination clusters are configured to replicate all files and processes on the nodes of the source cluster to the nodes of the destination cluster, wherein all replicated files and processes register with the single port manager, and wherein the single port manager is configured to communicate with the source cluster via a single port and to provide descriptors of the required replicated files and processes via a kernel.

Abstract: A method and a system for managing flat and routed clients in a cluster using single virtual IP (VIP) are provided herein. The method includes broadcasting an ARP request from a client to a cluster of nodes; monitoring the broadcasted ARP request at one of the nodes and ignoring the ARP request at all other nodes; in a case that the monitored ARP requests is associated with a different target VIP for same client IP, determining the client associated with the ARP request as a routed client, otherwise the client is determined as a flat client; applying at least one load balancing logic for assigning one of the nodes to the client associated with the ARP request, wherein both flat clients and routed clients are treated as independent clients counted separately; and notifying the client associated with the ARP of a MAC address of the assigned node.

Abstract: A method and a system for managing flat and routed clients in a cluster using single type of virtual IP (VIP) are provided herein. The method includes broadcasting an ARP request from a client to a cluster of nodes; monitoring the broadcasted ARP request at one of the nodes and ignoring the ARP request at all other nodes; in a case that the monitored ARP requests is associated with a target VIP other than a respective client IP, determining the client associated with the ARP request as a routed client, otherwise the client is determined as a flat client; applying at least one load balancing logic for assigning one of the nodes to the client associated with the ARP request, wherein both flat clients and routered clients are treated as independent clients counted separately; and notifying the client associated with the ARP of a MAC address of the assigned node.
