Abstract: Aspects of a cloud service framework are described. In some examples, a noncompliance event is received. The noncompliance event is identified using parameters detected from a deployment of hardware resources and software resources provided by a cloud service according to a service level agreement (SLA). An application programming interface (API) associated with the noncompliance event is identified. The API is disabled by updating an API availability status. A request to invoke the API is received, and the API is prevented from being forwarded to a backend service that provides the API.

Abstract: Embodiments provide data in-flight (DIF) services to software applications such as virtual machines (VMs) at an application level without requiring modification to established storage protocols. In exemplary embodiments, a storage controller transmits an advertisement of one or more data in-flight (DIF) services supported by a storage container of the storage controller. One or more DIF services communication path is created with attributes corresponding to the DIF services supported by the storage container. The storage controller receives, over the DIF services communication path, tagged data that can include data transmitted by a virtual machine (VM) for storage in the storage container.

Abstract: A virtualization platform can discover capabilities of data devices connected in a virtual infrastructure. The virtualization platform allows a user (e.g., system administrator) to specify a policy profile for a virtual machine in terms of performance and data handling parameters. The virtualization platform can provision a virtual machine comprising data devices having a combined capability that matches the policy profile. Enforcement of a policy profile can be made when I/O is performed by a virtual machine.

Abstract: Embodiments perform capability discovery, policy management, and policy enforcement to provide data in-flight (DIF) services to virtual machines (VMs) without requiring modification to established storage protocols. In exemplary embodiments, a management device receives advertisements of DIF services supported by network nodes. The management device groups the advertised DIF services into a DIF services policy. The management device associates a host and a communication path. The management device enforces the DIF services policy by storing a unique number that causes transmission of data along the communication path.

Abstract: Certain embodiments described herein are generally directed to enforcing application-specific quality of service (QoS) requirements over a storage network. The method for enforcing application-specific quality of service (QoS) requirements over a storage network includes receiving an input-output (I/O) command from a virtual machine executing an application, wherein the I/O command corresponds to an I/O request generated by the application and is tagged with a QoS classification corresponding to QoS requirements of the application, determining a QoS value corresponding to the QoS classification of the I/O command, and transmitting a data frame including the I/O command and the QoS value to a target network adapter through a switch fabric in a network, the switch fabric having a plurality of switches each configured to forward the data frame based on the QoS value.

Abstract: Memory management in a computer system may include allocating memory pages from a physical memory of the computer system to applications executing on the computer system. The memory pages may be associated with memory management tags. One or more memory pages may be identified for processing from the physical memory based on the memory management tags that the memory pages are associated with. The processed memory pages may then be designated as un-allocated memory pages for subsequent allocation to applications executing on the computing system.

Abstract: Exemplary methods, apparatuses, and systems include a management server receiving, from each of a plurality of switches, physical topology data of network nodes. The physical topology data includes identifiers of hosts connected to each of the switches and identifiers of storage connected to each of the switches. The management server transmits a query to each of the network nodes and receives, in response to each query, the capabilities of each network node. In response to receiving a request to create a cluster of the hosts, the management server selects hosts and storage from the physical topology data to create the cluster. The hosts and storage are selected based upon the capabilities received from each network node. The management server determines transport protocol login service parameters based upon the received storage capabilities and transmits the parameters to one or more of the plurality of switches, hosts, and storage.

Data transmitted by the software application to a destination is tagged based on the DIF services policy associated with the software application and transmitted to the destination.

Abstract: Exemplary methods, apparatuses, and systems a management server receiving, from a switch, an indication of network congestion at the switch. The indication includes one or more contributors to the network congestion. In response to the indication of network congestion, the management server identifies one or more hosts running the identified contributor(s) and transmits an instruction to the host(s) to restrict network traffic originated by the contributor(s). For example, the restriction may include a reduction in the contributor's I/O queue depth. If the reduction in traffic does not remedy the congestion, the management server may receive a further indication of congestion and further instruct the host(s) to restrict identified contributor network traffic. For example, the contributors may have their I/O queue depth reduced exponentially until congestion is relieved.

Abstract: This document describes techniques for efficient data deployment for a parallel data processing system. In one embodiment, a virtualization platform running a parallel processing application that includes one or more virtual data nodes receives a first command to write a data block to a storage device. The platform then determines whether the first command was sent by a first virtual data node. If the first command was sent by a first virtual data node, the platform then 1) writes, the data block to a first location in the storage device; 2) returns the first location to the first virtual data node and 3) determines whether the data should be replicated. If the data should be replicated, the platform instructs the storage device to make a copy of the data block to a second location in the storage device and storing the second location in a tracking structure.
