  • Analysis of Server Clustering Its Uses And
    Maksim Paderin ANALYSIS OF SERVER CLUSTERING ITS USES AND IMPLEMENTATION Bachelor’s thesis Information Technology 2017 Author (authors) Degree Time Maksim Paderin Information December 2017 Technology Title 73 pages Analysis of server clustering, its uses and implementation 0 pages of appendices Commissioned by South-Eastern University of Applied Sciences Supervisor Matti Juutilainen Abstract Clustering became an extremely important networking technology in the latter days. It perfectly coexists with other trending IT technologies and concepts such as virtualization, cloud computing and IoT. The goal of this study is to learn more about clustering as a concept, about co-existing technologies, and about operating systems which could help to form networks, and, specifically, clusters. Another goal of the study is to apply gained knowledge to practice and implement a working cluster. The practical part is targeted on the use of DigitalOcean and Amazon Web Services technologies in synergy with two very different operating systems, Linux and Windows. Keywords clustering, networking, servers, vmware, windows, linux, clouds, virtualization, docker, digitalocean, aws CONTENTS 1 INTRODUCTION .......................................................................................................... 6 2 SERVER CLUSTERING CONCEPTS .......................................................................... 7 2.1 Clusters as technology ........................................................................................... 7 2.2 Cluster roles and architecture

  • HP X3000 Network Storage Systems Product Overview
    QuickSpecs HP X3000 Network Storage Systems Product Overview IP-based gateway services for arrays/SANs and highly available shared storage solutions built on industry standards You made the decision to invest in a storage array, but now you've found that you still have file and application servers that aren't connected. So you're still spending time managing islands of storage and your array isn't meeting its full potential. Wouldn't it be nice to complete the consolidation to truly create one unified storage pool to expand and protect? HP X3000 Network Storage Systems boost the value of your array or SAN by adding Windows-powered IP-based gateway services to it. You'll spend less time and effort on maintenance and deliver a better return-on-investment for your array/SAN when you consolidate to a single, unified storage pool that can serve files to your clients and blocks to your servers via multiple protocols (FC/iSCSI or SAS/iSCSI). Industry-standards protect your investment by providing compatibility with your network and applications, and a Microsoft Cluster Server (MSCS) license is included to provide high availability and reduce downtime. What is an X3000 HP X3000 Network Storage Systems are enhanced Windows-powered gateway and shared storage Network Storage System? solutions for your medium business, workgroup, or datacenter environment. They are built on industry- standard HP ProLiant servers and come with the Microsoft® Windows Storage Server 2008 Enterprise operating system -- including cluster services -- pre-installed. They connect via Ethernet and add file, print, iSCSI, and management services to an array or SAN, or they can be used in conjunction with array storage to build an affordable and highly-available unified storage solution.

  • CLUSTER COMPUTING Introduction: a Computer Cluster Is a Group Of
    CLUSTER COMPUTING CLUSTER COMPUTING Introduction: A computer cluster is a group of linked computers, working together closely so that in many respects they form a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and/or availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability. The High Performance Computing (HPC) allows scientists and engineers to deal with very complex problems using fast computer hardware and specialized software. Since often these problems require hundreds or even thousands of processor hours to complete, an approach, based on the use of supercomputers, has been traditionally adopted. Recent tremendous increase in a speed of PC-type computers opens relatively cheap and scalable solution for HPC, using cluster technologies. The conventional MPP (Massively Parallel Processing) supercomputers are oriented on the very high-end of performance. As a result, they are relatively expensive and require special and also expensive maintenance support. Better understanding of applications and algorithms as well as a significant improvement in the communication network technologies and processors speed led to emerging of new class of systems, called clusters of SMP(symmetric multi processor) or networks of workstations (NOW), which are able to compete in performance with MPPs and have excellent price/performance ratios for special applications types. A cluster is a group of independent computers working together as a single system to ensure that mission-critical applications and resources are as highly available as possible.
