1. A system comprising:

  • a target server with a first programmable network interface card that includes programmed logic for localized detection of liveness of said target server via at least one liveness parameter that is maintained local to said target server, said target server being associated with a server farm network; and

    a management server connected to said target server via the server farm network, said management server having a second programmable network interface card that includes programmed logic for receiving, from the first programmable network interface of the target server, the liveness parameter from the target server and determining, based on a value of said liveness parameter whether the target server is operational within the server farm network, wherein said server farm network is managed by the management server and said server farm network is separate from an external data network for connecting client systems to said server farm network.
