  • XIV Storage System GEN3 Product Guide for Model 214 And
    Front cover XIV Storage System Product Guide Bert Dufrasne Dietmar Dausner Nancy Kinney Christopher Moore Markus Oscheka Eric Zhang Product Guide XIV Storage System Product Guide The IBM® XIV® Storage System is a high-end flash optimized, fully scalable enterprise disk storage system that is based on a grid of standard hardware components. As shown in Figure 1, the architecture of the system is designed to deliver out-of-the box performance and ease of management while harnessing the high capacity and cost benefits of serial-attached SCSI (SAS) drives. The XIV Gen3 systems (and the Model 314 in particular) offer powerful real-time compression that is based on the IBM Random Access Compression Engine (RACE) technology. Figure 1 XIV architecture This IBM Redbooks® Product Guide offers a brief overview of the IBM XIV Gen3 Storage System hardware and software features. © Copyright IBM Corp. 2016. All rights reserved. ibm.com/redbooks 1 Introducing Model 314 The IBM XIV Storage System Model 314 is the latest addition to the XIV family. It is a hardware-enhanced XIV Gen3 storage system that is targeted for customers that are requesting high-utilization of Real-time Compression™ (RtC), without performance degradation. Compared to Model 214, its compressed capacity is now up to five times larger. On compressed workloads, performance sees an improvement of 50% or more (with IBM XIV software version 11.6.1). It can also compress smaller volumes. With Model 314, the Real-time Compression (RtC) feature is included in the IBM XIV license. Therefore, there is no need to obtain other RtC licenses and the feature is enabled by default.

  • 2017-08 Analytic Success Stories
    Analytic success stories – cross-industry search – Fallstudienseminar SS 2017 vorgelegt von: Julian Vasel, [email protected] Fenja Laur, [email protected] Daniel Grombach, [email protected] Alexander Kruczek, [email protected] Sebastian Kirschner, [email protected] Stefanie Friedrich, [email protected] Moritz Wegner, [email protected] Katharina Schinnagel, [email protected] Ronja Semmelroth, [email protected] Betreuer: Prof. Dr. Roland Zimmermann Introduction Business Intelligence becomes more and more important in our daily life. It is very comfortable and helpful to benefit from real time data. When someone wants to travel by car and needs to know how the traffic situation develops, analytics has the answer for the problem and shows the best and fastest route without traffic jam. But especially for companies analytics become more and more important. Through BI, they can get reports with one mouse-click, know exactly what customers want and increase their revenue. That is the reason why we were looking for companies who realise great achievements through working with external partners. The external partners were: Microsoft, IBM, SAP, Salesforce, Sisense, SAS, Microstrategy, ClearstoryData, Tableau, Qlik, Tibco and Oracle. While we found most of the success stories on the manufacturer’s homepages, there were also some in newspapers, reports and on other websites. We analyzed our stories from problem to solution up to benefits. Following this, we evaluated and connected our data and constructed a summary. Management Summary Our project during the case study seminar was to find out how analytic solutions could help to improve the success of different companies. The basis for those evaluations were success stories from different providers of analytic solutions.
