Transcript of "Open systems Specialists: XiV Storage Reinvented"

  1. 1. XIV – Storage Reinvented Marcus König Systems Consultant (Open Systems Specialists) IBM Insight Forum 09 Make change work for you ®
  2. 2. 2 XIV Showcase - Agenda - XIV Overview Live demonstration of an XIV system Questions & Answers IBM Insight Forum 09 Make change work for you ®
  3. 3. 3 Traditional Enterprise Storage Solutions Scale Up Building blocks: Interface Interface Interface • Disks/Flash • Cache Controllers • Controllers • Interfaces PERFORMANCE • Backplane RELIABILITY = $$$ SCALABILITY Cache With this legacy architecture, scalability is achieved by using more powerful (and more expensive) components. JBOD JBOD IBM Insight Forum 09 Make change work for you ®
  4. 4. 4 XIV Showcase - Hardware Overview - FC Host Data Module Host iSCSI Data Module Host Ethernet Data Module Data Module UPS UPS UPS
  5. 5. 5 XIV Showcase - Differences - highly scaleable 1TB Disk rebuild in under 40 min no performance optimisation necessary no hotspots throughout the whole system tier-less architecture ease of use IBM Insight Forum 09 Make change work for you ®
  6. 6. 6 XIV Showcase - Storage Distribution Algorithm - Each volume (LUN) is spread across all drives Data is “cut” into 1MB “partitions” and stored on the disks XIV algorithm automatically distributes partitions across all disks in the system pseudo-randomly Interface Interface Interface Switching Data Module Data Module Data Module IBM Insight Forum 09 Make change work for you ®
  7. 7. 7 XIV Showcase - Storage Distribution Algorithm - Data distribution only changes when the system changes Equilibrium is kept when new hardware is added Equilibrium is kept when old hardware is removed Equilibrium is kept after a hardware failure Data Module 1 Data Module 2 Node 1 Node 2 Data Module 3 Node 3 IBM Insight Forum 09 Make change work for you ®
  8. 8. 9 XIV Showcase - Storage Distribution Algorithm - Data distribution only changes when the system changes Equilibrium is kept when new hardware is added Equilibrium is kept when old hardware is removed Equilibrium is kept after a hardware failure Data Module 1 Data Module 2 Data Module 3 Data Module 4 Node 4 [ hardware upgrade ] IBM Insight Forum 09 Make change work for you ®
  9. 9. 10 XIV Showcase - Storage Distribution Algorithm - Data distribution only changes when the system changes Equilibrium is kept when new hardware is added Equilibrium is kept when old hardware is removed Equilibrium is kept after a hardware failure [ hardware failure ] Data Module 1 Data Module 2 Data Module 3 Data Module 4 IBM Insight Forum 09 Make change work for you ®
  10. 10. 11 XIV Showcase - Live Demo - short overview GUI sample Host definition sample LUN creation and Host attachment Snapshot Events and statistics IBM Insight Forum 09 Make change work for you ®
