  • 1. PC versus POSFor professional retailing
  • 2. Retail IT SpecialistsReasons for downtime 53 % of all service calls were related to hardware Reasons for the service call problems 8% CPU / RAM / Fans 4% Drives 2% Power supply 18 % 2% Exp. cards / LAN 2% Others 47 % 13 % Printer 10 % Cash drawer 35 % 5% Scanner 3% Display 3% Keyboard Not included, downtime due to: Source:  Power failures Wincor Nixdorf ITS failure  Server and network failures statistics 4. Q. 1999  Non-availability of supplies (paper, ribbon cartridges, etc.) Based on BEETLE /L  Missing change configurations, 90% of which  etc. were DOS systems.
  • 3. Retail IT SpecialistsReasons for downtime 47 % of all service calls were related to software issues and the user. Reasons for the failure:  Installation faults  Wrong setup parameters 47 %  Operating system & driver bugs  Compatibility issues with SW versions  Network problems  User faults  ... The software and user related Source: call rate share will increase Wincor Nixdorf ITS failure statistics 4. Q. 1999 with the use of more complex Based on BEETLE /L operating systems such as configurations, 90% of which Windows and Linux. were DOS systems.
  • 4. Retail IT SpecialistsIceberg Costs in the POS environment Acquisition Costs: 20-25% Running Costs: 75-80% The acquisition costs are only the top of the iceberg of the total cost of ownership. The lion´s share are the running costs for training, administration, maintenance and system downtime.
  • 5. Retail IT SpecialistsTCO TCO  Reduce running Total Cost of Ownership costs Downtime  Optimize Administration serviceability 60-70% Service Support  Increase system Power consumption ~75% availability Installation Training etc. HW & SW acquisition ~25% costs Taking TCO to the next level Typical for POS systems over a 5-year period
  • 6. Retail IT SpecialistsReduce complexity SIMPLER CHEAPER  Plug & play  Cost reduction  Useability  Power consumption  Ergonomics  Serviceability  Simplify business /  Optimized TCO service processes BETTER  Improved performance e.g. printer speed  Increased resources  Improved MTBF  High quality
  • 7. Retail IT SpecialistsFeatures and functions that influence TCO Function/Feature Customer benefit Scalable product family Tailor-fitted configurations Versatile usage Efficient serviceability Long-term availability Homogeneous IT environment PC & Retail standards Vendor independency Powered interfaces Higher reliability Embedded OS Reduced complexity Management readiness Efficient remote administration Proven technology Higher availability Integrated UPS option Reduced downtime Mobile and ULV processors Reduced running costs Multi-modular product concept Cost-effective swap service Solid state memory (uDOC) Increased data security International approvals World-wide availability
  • 8. Retail IT SpecialistsLifecycle issues PC: New model every 4-6 months Year 1 Year 2 Year 3 Year 4 BEETLE: Long availability of systems and spare parts Take into consideration  Planned lifecycle of the POS systems (2, 5, 8 or more years?)  Rollout size / schedule  Availability of spare parts / system replacements  Pros and cons of homogeneous and heterogeneous IT environments
  • 9. Retail IT SpecialistsSystem environments Homogeneous BEETLE Heterogeneous PC Environment Environment  Same motherboard  Different motherboards  Same processors  Different processors  Same BIOS  Various BIOS´  Same LAN adapter  Different LAN adapters  Same video adapter  Different video adapters  Same video BIOS  Various video BIOS´  Embedded OS  Desktop OS  Same administration and  Various administration and management tools management tools Which system platform is easier to manage and to maintain ?

  • 15. Retail IT SpecialistsPower • One power outlet for the whole • Several power supplies / more power configuration outlets required • Lower power consumption • Greater heat dissipation / higher • Higher reliability power consumption • Simple cable management • Many potential points of failure • Complex cable management
  • 16. Retail IT SpecialistsEmbeded OS A software provider can individually configure an embedded OS to meet the retailer´s exact requirements Reduce i t to the MAX Advantages of an embedded operating system: • Less overhead – better performance • No unneeded functions – increased stability and security • Purpose-optimized – reduced hardware requirements • Lower OS licensing costs • Long availability  Licensing  Support
  • 17. Retail IT SpecialistsUPS „Power problems are the source of 50% of data loss for computer installations.“ Contingency Planning Research Optional, integrated UPS for BEETLE /M and /XL-II:  20 minutes system retension time  Supports the system and system powered peripherals
  • 18. Retail IT SpecialistsProven technology  Sealed housing reduces dust RF collection Security interference hazards  Onboard components optimize system availability Humidity  Designed for 24 / 7 operation Dust & dirt  Flexible usage (POS, kiosk, management or self-scanning terminal)  Enhanced environmental conditions  Resistant against static charges, RF interference, Temperature power surges External  Robust, easy-to-service Static charges influences aluminum housing
  • 19. Retail IT SpecialistsDust Lint dust can influence the MTBF values (Mean Time Between Failure) of IT systems in a negative way With the increasing system performance the amount of air circulation needed to cool the components inside a system increases as well The BEETLEVIEW agent monitors temperatures and fan speeds Lint filter The lint filter is a unique feature of the BEETLE /M and BEETLE M- II models
