Oblivious RAM in Scalable SGX
The prevalence of cloud storage has yielded significant benefits to consumers. Trusted Exe- cution Environments (TEEs) have been introduced to protect program execution and data in the cloud. However, an attacker targeting the cloud storage server through side-channel attacks can still learn some …

A resource management framework for cloud computing
… virtualization and feature-rich enterprise storage, are further driving the wide-spread adoption of virtualized cloud environments. Many challenges arise when designing resource management techniques for both native and virtualized data centers. First, parameter tuning of MapReduce jobs for …

Approximation algorithms for resource allocation optimization.
Nowadays, data storage, server replicas/mirrors, virtual machines, and various kinds of services can all be regarded as different types of resources. These resources play an important role in today’s computer world because of the continuing advances in information technology. It is usual that …

Next Generation Design of a Frequency Data Recorder Using Field Programmable Gate Arrays
… internet to a centralized data management and storage server. By distributing a number of these identical systems throughout the three major North American power systems, Virginia Tech has created a Frequency Monitoring Network (FNET). The FNET is composed of these distributed FDRs as well as …

Harnessing metadata characteristics for efficient deduplication in distributed storage Systems
As storage capacity requirements grow, storage systems are becoming distributed, and that distribution poses a challenge for space savings processes. In this thesis, I design and implement a mechanism for storing only a single instance of duplicated data within a distributed storage system which …

Improving Operating System Security, Reliability, and Performance through Intra-Unikernel Isolation, Asynchronous Out-of-kernel IPC, and Advanced System Servers
… a large attack surface. Microkernel OSs and multiserver OSs improve security and reliability through isolation, but they come at a performance cost due to crossing privilege layers through IPCs, system calls, and mode switches. Library OSs, on the other hand, implement kernel components as …

Implementing accelerated key-value store: From SSDs to datacenter servers
Efficient management of storage is a primary concern in all systems dealing with Big Data. In the modern era, flash-based solid-state drives (SSDs) are widely adopted in computer systems, slowly replacing hard disk drives. As many kinds of data generated and collected these days are not …

A Holistic Approach to Lowering Latency in Geo-distributed Web Applications
… is impacted by: (i) User to Application server (front-end) latency which includes downloading and parsing web pages, retrieving further objects requested by javascript executions; and (ii) Application and storage server(back-end) latency which includes retrieving meta-data required for an …

Algorithms for Data Migration
… is concerned with the problem related to data storage and management. A large storage server consists of several hundreds of disks. To balance the load across disks, the system computes data layouts that are typically adjusted according to the workload. As workloads change over time, the system …

DepMap: Dependency Mapping of Applications Using Operating System Events
… examples of this, but even relatively isolated servers often depend on shared, network-accessible resources. This standardization around service layers abstracts aspects of service delivery, but often entails a large collection of component systems. The complexity that is abstracted from a …

Chorus: Model Kowledge Base for Perfomance Modeling in Datacenters
… an experimental evaluation on a multi-tier server platform, using several industry- standard benchmarks. Our results show that Chorus is a flexible modeling framework and knowledge base for validating, extending and reusing existing models while adapting to new situations.
