摘要： A method and apparatus of providing high performance and highly scalable storage acceleration includes a cluster node-spanning RAM disk (CRD) interposed in the data path between a storage server and a computer server. The CRD addresses performance problems with applications that need to access large amounts of data and are negatively impacted by the latency of classic disk-based storage systems. It solves this problem by placing the data the application needs into a large (with respect to the server's main memory) RAM-based cache where it can be accessed with extremely low latency, hence improving the performance of the application significantly. The CRD is implemented using a novel architecture which has very significant cost and performance advantages over existing or alternative solutions.

摘要： An approach for allocating resources to an apparatus based on resource requirements generally involves a resource allocator receiving a request that specifies resource requirements for the apparatus. A resource allocator determines whether resources are available that satisfy the resource requirements. If resources are available that satisfy a resource requirement, the resource allocator indicates that the resource requirement is fulfilled and the resources are allocated to the apparatus. If resources are not available that satisfy a resource requirement, the resource allocator indicates that the resource requirement is not fulfilled and the resources are not allocated to the apparatus. The apparatus is implemented based on the allocated resources. A resource requirement can be optional so that if the optional resource requirement is not fulfilled, the apparatus can still be implemented. Conversely, a resource requirement can be necessary so that if the necessary resource requirement is not fulfilled, the apparatus is not implemented.

摘要： A system for screening data packets transmitted between a network to be protected, such as a private network, and another network, such as a public network. The system includes a dedicated computer with multiple (specifically, three) types of network ports: one connected to each of the private and public networks, and one connected to a proxy network that contains a predetermined number of the hosts and services, some of which may mirror a subset of those found on the private network. The proxy network is isolated from the private network, so it cannot be used as a jumping off point for intruders. Packets received at the screen (either into or out of a host in the private network) are filtered based upon their contents, state information and other criteria, including their source and destination, and actions are taken by the screen depending upon the determination of the filtering phase. The packets may be allowed through, with or without alteration of their data, IP (internet protocol) address, etc., or they may be dropped, with or without an error message generated to the sender of the packet. Packets may be sent with or without alteration to a host on the proxy network that performs some or all of the functions of the intended destination host as specified by a given packet. The passing through of packets without the addition of any network address pertaining to the screening system allows the screening system to function without being identifiable by such an address, and therefore it is more difficult to target as an IP entity, e.g. by intruders.

摘要： An approach for allocating resources to an apparatus based on suspendable resource requirements generally involves a resource allocator determining that a particular resource requirement for an apparatus is to no longer be satisfied, such as for a suspendable resource requirement. The resource allocator de-allocates the one or more resources that satisfy the particular resource requirement from the apparatus. The resource allocator obtains and stores state information for a de-allocated resource so that another resource, which may or may not be the same as the resource that was de-allocated, can be allocated to the apparatus based on the stored state information with an acceptable loss of state.

摘要： An approach for allocating resources to an apparatus based on alternative resource requirements generally involves a resource allocator determining that a resource that satisfies a resource requirement is not available, and based on the resource not being available, the resource allocator determines that another resource that satisfies another resource requirement is available. The resource allocator allocates the other resource to the apparatus, thereby allowing the apparatus to be implemented based on the other resource. The resource requirements are alternatives so that if the one alternative resource requirement cannot be fulfilled, the other alternative resource requirement can be fulfilled. Some alternatives can be preferred over other alternatives in a set of alternative resource requirements. In general, in a set of “n” alternative resource requirements, “m” resource requirements can be specified to be fulfilled, where “m” is less than “n” and “n” is two or greater.
摘要翻译：基于替代资源需求将资源分配给设备的方法通常涉及资源分配器，其确定满足资源需求的资源不可用，并且基于资源不可用，资源分配器确定满足另一资源的另一资源资源需求可用。资源分配器将另一资源分配给设备，从而允许基于其他资源来实现该设备。资源需求是替代方案，因此如果一个替代资源需求不能满足，则可以满足另一个替代资源需求。在一组替代资源需求中，一些替代方案可以优于其他替代方案。一般来说，在“n”个替代资源要求的集合中，可以指定满足“m”个资源要求，其中“m”小于“n”，“n”为2或更大。

摘要： A method for efficient communications with a cluster-based architecture preserves various aspects of integrity throughout one or more connections with a client, even in the midst of connection migration between nodes in the cluster. According to one aspect, the invention provides a mechanism for preventing the loss of packets arising from a TCP connection migration within the cluster. According to another aspect, the invention provides a mechanism for uniquely identifying conflicting TCP connections migrated to a common node. According to a still further aspect, the invention provides a distributed TCP timestamp mechanism so that the sender and receiver will have a consistent view of the timestamp even when each node has different local clock values and regardless of how many times the socket has been migrated.

摘要： An approach for provisioning network devices generally involves supplying boot data to network devices over a network so that the network devices can be booted up in an imaging mode or an application mode, depending upon the particular boot data supplied to the network device. When booted up in the imaging mode, imaging data can be downloaded and stored on network devices. When booted up in the application mode, the network devices execute one or more programs contained in the image data stored on the network devices. The first and second boot data may be in the form of boot loader scripts. Furthermore, the first and second boot data may be provided to the network device in the payload of a dynamic host configuration protocol (DHCP) reply. The DHCP reply may be generated and provided by a DHCP server to the network device in response to receiving a DHCP request from the network device. The approach may be implemented using a secure network environment.

摘要： The present invention relates generally to a method for efficient I/O handling in a cluster-based architecture. According to one aspect, the invention enables efficient scheduling of TCP connection migrations within a cluster. According to another aspect, the invention enables I/Os performed as TCP handoff operations to coexist on the same TCP/IP connection with I/Os performed as remote operations.
