Book excerpt: File system designers continue to look to new architectures to improve scalability. Object-based storage diverges from server-based (e.g. NFS) and SAN-based storage systems by coupling processors and memory with disk drives, delegating low-level allocation to object storage devices (OSDs) and decoupling I/O (read/write) from metadata (file open/close) operations. Even recent object-based systems inherit decades-old architectural choices going back to early UNIX file systems, however, limiting their ability to effectively scale to hundreds of petabytes. We present Ceph, a distributed file system that provides excellent performance and reliability with unprecedented scalability. Ceph maximizes the separation between data and metadata management by replacing allocation tables with a pseudo-random data distribution function (CRUSH) designed for heterogeneous and dynamic clusters of unreliable OSDs. We leverage OSD intelligence to distribute data replication, failure detection and recovery with semi-autonomous OSDs running a specialized local object storage file system (EBOFS). Finally, Ceph is built around a dynamic distributed metadata management cluster that provides extremely efficient metadata management that seamlessly adapts to a wide range of general purpose and scientific computing file system workloads. We present performance measurements under a variety of workloads that show superior I/O performance and scalable metadata management (more than a quarter million metadata ops/sec).

Although it is implemented with Debian GNU/Linux, the content can be applied to other UNIX flavors.
Download or read book Performance Scalability and Robustness in Distributed File Tree Copy written by Christopher Robert Sutton and published by . This book was released on 2018 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As storage needs continually increase, and network file systems become more common, the need arises for tools that efficiently copy to and from these types of file systems. Traditional copy tools like the Linux cp utility were originally created for traditional storage systems, where storage is managed by a single host machine. cp uses a single-threaded approach to copying files. Using a multi-threaded approach would likely not provide an advantage in this system since the disk accesses are the bottleneck for this type of operation. In a distributed file system the disk accesses are spread across multiple hosts, and many accesses can be served simultaneously. Volumes in a distributed file system still look like a single storage device to the operating system of a client machine, so traditional tools like cp can still be used, but they cannot take advantage of the performance increase offered by a distributed, multi-node approach. While some research has been done in this area and some tools have been created there are still shortcomings in the area, particularly when it comes to scalability and robustness to process failure. The research presented here attempts to adress these shortcomings. The software created in this project was tested in a variety of enviornments and compared to other other tools that have attempted to make improvements in these areas. In the area of scalability, this software performed well from a small cluster to large high-performance-computing cluster. In comparisons to other tools, the performance was comparable to or better than the other tools measured. The unique contribution of this project is in the area of robustness, which other tools have not attempted to address. The software allows the use to specify a minimum number of processes that can fail without losing progress or requiring a restart of the copy job. This means process death can be tolerated, or resources can be diverted after the start of the copy job. This is especially helpful in very large, long-running jobs. Many clusters are made with low-cost, consumer-grade hardware which is susceptible to failure. A study entitled 'Failure Trends in a Large Disk Drive Population' [2], published in the proceedings of the USENIX FAST'07 conference, looked at the failure rate of disk drives across Google's various services. It found that a large number of drives fail within a few years. Drive failure rate was somewhat high within the first few months, weeding out the lower quality drives, but at the two and three year mark as many as eight percent of drives failed per year. This high rate shows the importance of software like this that can tolerate these types of failures."--Boise State University ScholarWorks.

Book excerpt: Mastering Cloud Computing is designed for undergraduate students learning to develop cloud computing applications. Tomorrow's applications won't live on a single computer but will be deployed from and reside on a virtual server, accessible anywhere, any time. Tomorrow's application developers need to understand the requirements of building apps for these virtual systems, including concurrent programming, high-performance computing, and data-intensive systems. The book introduces the principles of distributed and parallel computing underlying cloud architectures and specifically focuses on virtualization, thread programming, task programming, and map-reduce programming. There are examples demonstrating all of these and more, with exercises and labs throughout. - Explains how to make design choices and tradeoffs to consider when building applications to run in a virtual cloud environment - Real-world case studies include scientific, business, and energy-efficiency considerations

Download or read book Network Analysis Architecture and Design written by James D. McCabe and published by Elsevier. This book was released on 2010-07-26 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, networking has had little or no basis in analysis or architectural development, with designers relying on technologies they are most familiar with or being influenced by vendors or consultants. However, the landscape of networking has changed so that network services have now become one of the most important factors to the success of many third generation networks. It has become an important feature of the designer's job to define the problems that exist in his network, choose and analyze several optimization parameters during the analysis process, and then prioritize and evaluate these parameters in the architecture and design of the system. Network Analysis, Architecture, and Design, Third Edition, uses a systems methodology approach to teaching these concepts, which views the network (and the environment it impacts) as part of the larger system, looking at interactions and dependencies between the network and its users, applications, and devices. This approach matches the new business climate where customers drive the development of new services and the book discusses how networks can be architected and designed to provide many different types of services to customers. With a number of examples, analogies, instructor tips, and exercises, this book works through the processes of analysis, architecture, and design step by step, giving designers a solid resource for making good design decisions. With examples, guidelines, and general principles McCabe illuminates how a network begins as a concept, is built with addressing protocol, routing, and management, and harmonizes with the interconnected technology around it. Other topics covered in the book are learning to recognize problems in initial design, analyzing optimization parameters, and then prioritizing these parameters and incorporating them into the architecture and design of the system. This is an essential book for any professional that will be designing or working with a network on a routine basis. - Substantially updated design content includes ad hoc networks, GMPLS, IPv6, and mobile networking - Written by an expert in the field that has designed several large-scale networks for government agencies, universities, and corporations - Incorporates real-life ideas and experiences of many expert designers along with case studies and end-of-chapter exercises
