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:
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.
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:
A method processes input-output commands (IOs) in a storage system. The storage system receives an IO including first and second identifiers. The first identifier is used to direct the IO to the storage system. At the storage system, the method retrieves the second identifier from the IO and translates the second identifier to a logical storage volume identifier. Then, the method executes the IO on storage locations referenced by a logical storage volume corresponding to the logical storage volume identifier.
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:
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 software application is associated with a DIF services policy indicating one or more DIF services to apply to the software application. 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 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.

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. Upon receiving an indication that the congestion is relieved, the management server instructs the host(s) to remove the restriction on network traffic.
