Abstract: One or more content delivery networks (CDNs) that deliver content objects for others is disclosed. Content is propagated to edge servers through hosting and/or caching. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When a particular edge server does not have a copy of the content object from the URI, information is passed along a hierarchy (to a parent server, grandparent server, and, eventually, an origin server) until the content object is found. The origin server may be hosted in the CDN or at a content provider across the Internet. Once the content object is located in the hierarchical chain, the content object is passed back down the chain to the edge server for delivery. Optionally, the various servers in the chain may cache or host the content object as it is relayed.

Abstract: The cloud storage services are extended with a cloud storage service access protocol that enables users to specify a desired storage tier for each data stream. In response to receiving storage tier specifiers via the protocol, the cloud storage service performs storage operations to identify target storage devices having attributes matching those associated with the requested storage tier. The cloud storage service stores a data stream from the storage client in the identified target storage device associated with the desired storage tier. Storage tiers can be defined based on criteria including capacity costs; access latency; availability; activation state; bandwidth and/or transfer rates; and data replication. The cloud storage service protocol allows data streams to be transferred between storage tiers, storage devices to be activated or deactivated, and data streams to be prefetched and cached. The cloud storage services may charge storage clients based on storage tier use and associated operations.

Files are maintained in the sending directory and under control of the source node at least for a configurable amount of time until the file is safely transferred.

Abstract: Embodiments relate to systems and methods for storage allocation in the provisioning of virtual machines. A provisioning (or “cobbler”) server can interact with a local virtual machine installation client to initiate software provisioning to a set of virtual machines. The provisioning process can entail, for example, the selection and delivery of an operating system to the target set of virtual machines, as well as the installation of applications or other software. In conjunction with the provisioning process, the virtual machine installation client can identify and access a set of storage resources, such as hard disk or other storage, to be associated with the set of virtual machines, which themselves contain no local storage. That client can determine an allocation of the set of storage resources to each virtual machine in the set of virtual machines, for instance on a pro-rata basis or based on processing consumption or other factors.

Abstract: A mechanism for enabling session information to be shared across multiple processes in a multi-process environment is disclosed. There is provided a shared persistent memory-mapped file in a file system, which is mapped to the memory space of each of the processes. This file is used by all of the processes to store session information. Because the memory space of each process is mapped to the shared file, each process is able to access and manipulate all of the sessions in the system. Thus, sessions are no longer maintained on a process-specific basis. Rather, they are maintained on a centralized, shared basis. As a result, different requests pertaining to the same session may be serviced by different server processes without any adverse effects. Each process will be able to access and manipulate all of the state information pertaining to that session. By enabling session information to be shared, this mechanism eliminates the session management errors experienced by the prior art.

Abstract: A multiple computer system is disclosed in which n computers (M1, M2 . . . Mn) each run a different portion of a single application program written to execute only on a single computer. The local memory of each computer is maintained substantially the same by updating all computers with every change made to addressed memory locations. Contention can arise when the same memory location is substantially simultaneously updated by two or more machines because of transmission delays and latency of the communications network interconnecting all the computers. In particular a method of detecting contention is disclosed which utilizes a count value indicative of the number of the sequence of occasions on which each memory location has been updated. Contention is indicated if the currently stored count value and the incoming updating count value are the same.

Abstract: A system and method for offloading network processes from main processors of a storage system and performing them on parallel processing modules. Embodiments of the present invention allocate resources such as memory and/or buffers to particular connections between various storage operating system processes or between storage operating system processes and a network interface. Connections are identified by a connection identifier (CID) and are assigned particular buffers according to parameters such as buffer availability, connection priority, and/or maximum allocation thresholds. A connection associated with a CID is guaranteed access to a certain number of dedicated buffers. Deadlock is avoided even when an operating system process associated with a different CID attempts to exhaust available memory and/or buffers because such processes will only have access to their own allocated resources.

Abstract: Client computers are decoupled from file servers in a computer network, by placing a network node, also termed a file switch or file switch computer, between the client computers and the file servers. To the client computers, the file switch appears to be a file server having enormous storage capabilities and high throughput. To the file servers, the file switch appears to be a client as it delegates a single transaction received from a client computer to multiple file servers. The file switch aggregates the file servers' responses to the client computer's request and presents a single response back to the client computer. The file switch performs this transaction aggregation function in a manner that is transparent to both the client computers and the file servers.
