Globally sound and consistent configuration management for distributed datacenter components

Номер: US20120151443A1
Автор: Henning Korsholm Rohde, Kenneth Kai-Baun Ma, Matthew Kerner
Принадлежит: Microsoft Corp

Datacenter configuration needs to be managed. A configuration engine (CE) manages configuration data of clusters and/or datacenters. The CE allows users to check out, edit, and check in configuration components. Versioned interfaces are placed between configuration components through data contracts. The CE supports the expression of constraints that ensure global consistency across configuration components and versions, isolates changes in the datacenter from structural changes in configuration components, and enables partial configuration branching to allow for active snapshots that enable configuration rollback. The CE ensures that types are consistent and constraints are satisfied at check-in time to eliminate unsound or inconsistent configuration in the first place. When the active configuration in the datacenter changes, multiple versions of configuration may be simultaneously deployed for a window of time. The managed set of configuration is permitted to have multiple active versions during these transitional windows to reflect the reality in the datacenter.

Dynamic reduction of stream backpressure

Номер: US20130031556A1
Автор: John M. Santosuosso, Michael J. Branson, Ryan K. Cradick
Принадлежит: International Business Machines Corp

Techniques are described for eliminating backpressure in a distributed system by changing the rate data flows through a processing element. Backpressure occurs when data throughput in a processing element begins to decrease, for example, if new processing elements are added to the operating chart or if the distributed system is required to process more data. Indicators of backpressure (current or future) may be monitored. Once current backpressure or potential backpressure is identified, the operator graph or data rates may be altered to alleviate the backpressure. For example, a processing element may reduce the data rates it sends to processing elements that are downstream in the operator graph, or processing elements and/or data paths may be eliminated. In one embodiment, processing elements and associate data paths may be prioritized so that more important execution paths are maintained. In another embodiment, if a request to add one or more processing elements may cause future backpressure, the request may be refused.

Identifying application reputation based on resource accesses

Номер: US20130042294A1
Автор: Ameya Bhatawdekar, Anthony P. Penta, Elliott Jeb Haber, Ryan Charles Colvin
Принадлежит: Microsoft Corp

Malware detection is often based on monitoring a local application binary and/or process, such as detecting patterns of malicious code, unusual local resource utilization, or suspicious application behavior. However, the volume of available software, variety of malware, and sophistication of evasion techniques may reduce the effectiveness of detection based on monitoring local resources. Presented herein are techniques for identifying malware based on the reputations of remote resources (e.g., web content, files, databases, IP addresses, services, and users) accessed by an application. Remote resource accesses may be reported to a reputation service, which may identify reputations of remote resources, and application reputations of applications that utilize such remote resources. These application reputations may be used to adjust the application policies of the applications executed by devices and servers. These techniques thereby achieve rapid detection and mitigation of newly identified malware through application telemetry in a predominantly automated manner.

In a method for controlling a SAS expander to electronically connect to a RAID card in an electronic device, a plurality of different types for RAID cards, and configuration parameters of the SAS expander corresponding to each type of the RAID cards are preset. Information of the RAID card is read if the SAS expander is electronically connected the RAID card. The method further determines whether the RAID card matches the SAS expander. If the RAID card does not match the SAS expander, the configuration parameters of the SAS expander corresponding to the RAID card is read, and the read configuration parameters and the read information of the RAID card are written into a firmware file in the storage system. The method further stores the firmware file into a flash memory of the SAS expander.

A sink device in a Wireless Display (WD) system may send performance information feedback to a source device to adjust media data processing at the source device. The performance information feedback may include performance indicators of the WD system that are capable of being measured or calculated at the sink device based on received media data or request to adjust the transmission of media data. For example, the performance information feedback may include one or more of round trip delay, delay jitter, packet loss ratio, error distribution, and received signal strength indication (RSSI). The feedback channel may be piggybacked on a reverse channel architecture referred to as the User Input Back Channel (UIBC) implemented between the source device and the sink device.
