Autoreplica: Automatic Data Replica Manager In Distributed Caching And Data Processing Systems, Zhengyu Yang, Jiayin Wang, David Evans, Ningfang Mi Dec 2015

Autoreplica: Automatic Data Replica Manager In Distributed Caching And Data Processing Systems, Zhengyu Yang, Jiayin Wang, David Evans, Ningfang Mi

Zhengyu Yang

Nowadays, replication technique is widely used in data center storage systems for large scale Cyber-physical Systems (CPS) to prevent data loss. However, side-effect of replication is mainly the overhead of extra network and I/O traffics, which inevitably downgrades the overall I/O performance of the cluster. To effectively balance the trade-off between I/O performance and fault tolerance, in this paper, we propose a complete solution called “AutoReplica” – a replica manager in distributed caching and data processing systems with SSD-HDD tier storages. In detail, AutoReplica utilizes the remote SSDs (connected by high speed fibers) to replicate local SSD caches to protect …

Online Flash Resource Migration, Allocation, Retire And Replacement Manager Based On A Cost Of Ownership Model, Zhengyu Yang, Mrinmoy Ghosh, Manu Awasthi, Vijay Balakrishnan

Zhengyu Yang

A method for migrating disks includes: dividing a disk pool including a plurality of disks into a random zone and a sequential zone based on sequentiality and randomness of workloads running on the plurality of disks; monitoring a status of each disk in the disk pool based on a total cost of ownership (TCO); migrating one or more workloads of an overheated disk to an idle disk based on the status of each disk. The overheated disk has a first TCO higher than a migration threshold, and the idle disk has a second TCO lower than an idling threshold.

Online Flash Resource Allocation Manager Based On Tco Model, Zhengyu Yang, Mrinmoy Ghosh, Manu Awasthi, Vijay Balakrishnan

Zhengyu Yang

A method for allocating workloads based on a total cost of ownership (TCO) model includes receiving a workload; estimating a cost for allocating the workload to each disk of disks in a disk pool based on a TCO model; determining a disk among the disks in the disk pool that minimizes a TCO; and allocating the workload to the disk. The TCO model incorporates a plurality of cost factors for estimating costs for each disk in the disk pool for allocating the workload.

Memory Device Having A Translation Layer With Multiple Associative Sectors, Zhengyu Yang, Sina Hassani, Manu Awasthi Dec 2015

Memory Device Having A Translation Layer With Multiple Associative Sectors, Zhengyu Yang, Sina Hassani, Manu Awasthi

Zhengyu Yang

A method for providing a memory translation layer includes: receiving write request streams from a host computer; selectively storing each write request stream into a sequential zone, a K-associative zone, and a random zone of log blocks of a nonvolatile memory based on the characteristics. A first group of the write request streams that are sequential and start from a header page of a log block are stored in the sequential zone. A second group of the write request streams that are sequential but do not start from a header page of a log block are stored in the K-associative …

An Algorithm For Non-Steady Thermal Dynamics Finite Element Simulation And Differential Evolution, Xin Xie Dec 2015

An Algorithm For Non-Steady Thermal Dynamics Finite Element Simulation And Differential Evolution, Xin Xie

Xin Xie

Thermodynamic parameters of concrete are the significant condition in the preventing mass concrete cracking computation. The concrete inversion problem of thermodynamic parameters is a multi-parameter optimization problem. Differential Evolution is one of the optimization method of evolutionary and developed from GA (genetic algorithm). In this paper, non-steady temperature field finite element simulation and DE (Differential Evolution) combined together to establish DE inverse solution for concrete thermodynamic parameter including equivalent heat source method to realize water-pipe cooling simulation. The procedure was implemented in mode with high computational efficiency and being high accuracy. It is an effective way to select thermal parameters …

Mobile Devices: The Case For Cyber Security Hardened Systems, Maurice Dawson, Jorja Wright, Marwan Omar Dec 2015

Mobile Devices: The Case For Cyber Security Hardened Systems, Maurice Dawson, Jorja Wright, Marwan Omar

Maurice Dawson

Mobile devices are becoming a method to provide an efficient and convenient way to access, find and share information; however, the availability of this information has caused an increase in cyber attacks. Currently, cyber threats range from Trojans and viruses to botnets and toolkits. Presently, 96% of mobile devices do not have pre-installed security software while approximately 65% of the vulnerabilities are found within the application layer. This lack in security and policy driven systems is an opportunity for malicious cyber attackers to hack into the various popular devices. Traditional security software found in desktop computing platforms, such as firewalls, …

Effect Of The Distribution Of Faults And Operating Conditions On Afdd Performance Evaluations, David Yuill, James E. Braun Dec 2015

Effect Of The Distribution Of Faults And Operating Conditions On Afdd Performance Evaluations, David Yuill, James E. Braun

David Yuill

Automated fault detection and diagnosis (AFDD) tools are used to identify degradation faults that reduce
the performance and life of air-conditioning equipment. A recent methodology has been developed to
evaluate the performance of AFDD tools. The methodology involves feeding a library of input data to
an AFDD protocol and categorizing the results. The current paper describes a study that has been
conducted to assess the effect of using various input data sets in the evaluations. These input data sets
include different distributions of fault type, fault intensity, and operating temperatures. Case study
evaluations of three AFDD protocols in current widespread …

A Prediction Method For Overall Economic Value Of Fault Detection And Diagnostic Tools For Rooftop And Split Systems, David Yuill, James E. Braun Dec 2015

A Prediction Method For Overall Economic Value Of Fault Detection And Diagnostic Tools For Rooftop And Split Systems, David Yuill, James E. Braun

David Yuill

Fault detection and diagnostics (FDD) tools for air-conditioning application may perform well or poorly, but it is difficult to characterize this performance in a meaningful way. Some recently proposed evaluation techniques have provided various statistics to characterize FDD performance, but these results can be difficult for a potential adopter of FDD to understand. A new method of characterizing FDD performance by predicting the overall economic value of the FDD tool is proposed in this paper. It is applicable to FDD tools intended for air-cooled unitary air-conditioners, such as rooftop units (RTU) and split systems. The method gives an estimated dollar …

Normalized Effect Of Condenser Fouling And Refrigerant Charge On Performance Of Vapor Compression Air Conditioning Systems, Mehdi Mehrabi, David Yuill Dec 2015

Normalized Effect Of Condenser Fouling And Refrigerant Charge On Performance Of Vapor Compression Air Conditioning Systems, Mehdi Mehrabi, David Yuill

David Yuill

Several laboratory experiments have studied the effect of faults on vapor compression cycle air-conditioning
systems. There has been a particular focus on refrigerant charge variation, which is believed to be quite common in air conditioners, and a lesser focus on heat exchanger fouling. The majority of the published results evaluate the fault effects on particular system operating parameters in one unit. For example, the effect on capacity and
efficiency are typically evaluated. The results differ from one study to the next. The current paper summarizes the effects for all of the results available in the literature for condenser fouling and …
