摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided. The memory management mechanism permits both buffered sending and receiving of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism permits grouping of DMA buffers that can be shared among specified connections based on any number of attributes. The memory management mechanism further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system in bulk, and expedited transfer of data to the host system.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter is provided. The connection establishment mechanism provides the ability to offload connection establishment and maintenance of connection state information to the offload network adapter. As a result of this offloading of connection establishment and state information maintenance, the number of communications needed between the host system and the offload network adapter may be reduced. In addition, offloading of these functions to the offload network adapter permits bulk notification of established connections and state information to the host system rather than piecemeal notifications as is present in known computing systems.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, an improved mechanism for handling receipt of data packets in a system utilizing an offload network adapter. The offload network adapter may include logic that permits the offload network adapter to delay notification of data reception to the host system in different ways. The advantage of delaying the notice of data packet reception to the host system is the potential for aggregation of several data packets, which can arrive immediately after the first one, for example, in a single notification. Given a stream with continuous data packet arrival, a value may be set, either statically or dynamically, for notification delay and this value may be configurable for the host system per communication socket.

摘要： A mechanism for bottleneck avoidance is provided in an intelligent adapter. The mechanism allows the adapter to be used such that host/adapter system throughput is optimized. The bottleneck avoidance mechanism of the present invention determines when the adapter becomes a bottleneck. If certain conditions exist, then new connections are refused so that the adapter can process packets for existing connections. If certain other conditions exist, the adapter may migrate workload to the host processor for processing. These conditions may be determined by comparing memory usage or central processing unit usage to predetermined thresholds. Alternatively, the conditions may be determined by comparing adapter response time to host response time.

摘要： A redundancy elimination mechanism is provided, which applies aspects of duplicate block elimination and delta encoding at the block level. The redundancy elimination mechanism divides file objects into content-defined blocks or “chunks.” Identical chunks are suppressed. The redundancy elimination mechanism also performs resemblance detection on remaining chunks to identify chunks with sufficient redundancy to benefit from delta encoding of individual chunks. Any remaining chunks that do not benefit from delta encoding are compressed. Resemblance detection is optimized by merging groups of fingerprints into super fingerprints. This merging can be constructed to ensure that if two objects have a single super fingerprint in common, they are extremely likely to be substantially similar.

摘要： Images for information handling system manufacture and maintenance are created and managed by manipulating the images as virtual machines through a secure remote network interface, such as a virtual private network or virtual desktop infrastructure. Operating system and application installation and updates, such as service packs and patches, are performed on a virtual machine of the image to adjust the image as desired, and then the image is transformed for loading on physical information handling systems, such as newly manufactured information handling systems or deployed information handling systems in need of maintenance.

摘要： A system and method for optimizing a storage system to support full utilization of storage space are provided. With the system and method, data objects/containers of data objects are assigned retention values when they are created. These retention values may be dynamically modified based on a modification function associated with the data objects/containers. When storage space needs to be freed for the storage of new data objects/containers, the retention values of existing data objects/containers provide a prioritization as to which data objects/containers should be deleted from the storage system and the order by which these data objects/containers are to be deleted to make available storage space for the new data objects/containers. The identification of the data objects/containers that are to be deleted may be based on a dynamically modified delete threshold, a sorted list of retention values, or the like.

摘要： A system and method for optimizing a storage system to support short data object lifetimes and highly utilized storage space are provided. With the system and method, data objects are clustered based on when they are anticipated to be deleted. When an application stores data, the application provides an indicator of the expected lifetime of the data, which may be a retention value, a relative priority of the data object, or the like. Data objects having similar expected lifetimes are clustered together in common data structures so that clusters of objects may be deleted efficiently in a single operation. Expected lifetimes may be changed by applications automatically. The system automatically determines how to handle these changes in expected lifetime using one or more of copying the data object, reclassifying the container in which the data object is held, and ignoring the change in expected lifetime for a time to investigate further changes in expected lifetime of other data objects.
