Abstract: Methods and apparatus providing a dynamically sized, highly scalable and available server farm are disclosed. A Virtual Server Farm (VSF) is created out of a wide scale computing fabric (“Computing Grid”) which is physically constructed once and then logically divided up into VSFs for various organizations on demand. Each organization retains independent administrative control of a VSF. A VSF is dynamically firewalled within the Computing Grid. Allocation and control of the elements and topology in the VSF is performed by a Control Plane connected to all computing, networking, and storage elements in the computing grid through special control ports. No physical rewiring is necessary in order to construct VSFs in many different configurations, including single-tier Web server or multi-tier Web-server, application server, database server configurations.

Abstract: Methods and systems consistent with the present invention establish a virtual network on top of current IP network naming schemes. The virtual network uses a separate layer to create a modification to the IP packet format that is used to separate network behavior from addressing. As a result of the modification to the packet format, any type of delivery method may be assigned to any address or group of addresses. The virtual network also maintains secure communications between nodes, while providing the flexibility of assigning delivery methods independent of the delivery addresses.

A allocation and control of the elements in the VSF is performed by a Control Plane connected to all computing, networking, and storage elements in the computing grid through special control ports. The internal topology of each VSF is under control of the Control Plane. No physical rewiring is necessary in order to construct VSFs in many different configurations, including single-tier Web server or multi-tier Web-server, application server, database server configurations. Each tier of a multi-tier VSF (e.g.

Abstract: A Virtual Server Farm (VSF) is created out of a wide scale computing fabric (“Computing Grid”) which is physically constructed once and then logically divided up into VSFs for various organizations on demand. Allocation and control of the elements in the VSF is performed by a control plane connected to all computing, networking, and storage elements in the computing grid through special control ports. The control plane is comprised of a control mechanism hierarchy that includes one or more master control process mechanisms communicatively coupled to one or more slave control process mechanisms. The one or more master control process mechanisms instruct the slave control process mechanisms to establish VSFs by selecting subsets of processing and storage resources.

Abstract: An apparatus for allowing communications to a target host on a network to be upgraded from a non-secured session to a secured session. The apparatus including a processor; a memory coupled to the processor and storing an access control list; and a network interface coupled to the processor, the network interface communicating with a target host; wherein the memory is configured to cause the processor to: (1) create an access control entry for the target host in the access control list; (2) exchange security information with the target host; (3) update the entry for the target host to include the security information; and, (4) communicate with said target host using said security information.
