Abstract: Various systems and methods for evaluating and controlling high-availability configuration. For example, one method can involve detecting fault tolerance parameters that can be available within a datacenter. The method also involves identifying a set of fault tolerance parameters that applies to an application. Identifying the fault tolerance parameters that apply to the application involves detecting whether the application is associated with one or more high-availability applications. The method also involves generating an index value for the application. The index value is based on the fault tolerance parameters associated with the application and provides an objective measure of the fault tolerance of the application.

Abstract: Scheduling workloads based on detected hardware errors is provided. In response to determining that a hardware error is detected, it is determined whether the hardware error is a cache error. In response to determining that the hardware error is a cache error, it is determined whether execution of a workload on a processor is changing contents of a cache associated with the cache error more than a threshold value. In response to determining that the execution of the workload on the processor is changing the contents of the cache associated with the cache error more than the threshold value, it is determined whether the cache associated with the cache error is private to a core in the processor. In response to determining that the cache associated with the cache error is private to a core, the execution of the workload is scheduled on a different core of the processor.

Abstract: Methods and apparatus for associating each data packet in a media stream with logic corresponding to a particular quality-of-service (QoS) and/or error correction requirement. In an exemplary embodiment, each packet in the media stream is assigned a frame tag which designates a particular quality-of-service and/or error correction scheme for the corresponding packet. At least a portion of each packet is encoded according to the packet's designated quality-of-service as indicated by the frame tag. A receiver accesses the frame tags from within the transmitted media stream in order to determine the appropriate means for processing or decoding the encoded portion of each packet. In this manner, each packet within the media stream can have its own quality-of-service and/or error correction requirements and processing, thereby enhancing link efficiency and better enforcing QoS policy across the system.

Abstract: A method and system is disclosed for identification and removal of a memory sector prone to failure. The method performs satisfaction checks on the memory sector and monitors and stores returned Unsatisfied Checks (USC) for analysis by a pattern recognition algorithm. Once a first global iteration is pattern matched with a second global iteration from the sector, the method determines the period of the repetitive pattern. The method then identifies, as the sector prone to failure, the sector having the defined pattern and period. Once identified, the method uses a power management scheme to remove the sector prone to failure from further use by the memory system and displays to a user the details of the action taken.

Abstract: A method begins by determining that a disk drive of a slice server has been replaced with a new disk drive. The method continues by identifying a data slice that was stored on the disk drive and identifying a data segment based on the identified data slice. The method continues by identifying other slice servers that are storing other data slices of the encoded data segment. The method continues by retrieving, from the other slice servers, a sufficient number of the other data slices to reconstruct the data segment and decoding the sufficient number of the other data slices to reconstruct the data segment. The method continues by encoding the reconstructed data segment in accordance with the information dispersal algorithm to produce a new set of data slices. The method continues by selecting a data slice of the new set of data slices as a rebuilt data slice.
