For the last several months, there has been a lively debate in the industry about Emulex’s choice to use heat sinks on our 8Gb/s host bus adapters (HBAs). In contrast, QLogic, another market participant, chose not to put a passive cooling device on their HBA. But their decision can leave customers burned.

Emulex: Reliability by Design: Passive Cooling Technology from Emulex Labs

  1. 1. Emulex – Reliability by Design Passive Cooling Technology From Emulex Labs 1
  2. 2. Emulex LPe12000 Family vs QLogic QLE2562 Family 2
  3. 3. Testing Procedure No Airflow – Server fans blocked off to prevent airflow – Lab HVAC system may have had some effect Heat Soak – A minimum of 10 minutes was allowed for the parts to reach a stable temp, HBA ports idle of I/O traffic but ports are looped back Calibration – Spot temps were checked with a Omega contact thermocouple – HBAs were painted flat black to prevent reflections – The cameras general emissivity was adjusted to .92 to match the reflection properties of the painted surface and to coincide with the Omega temps IR Camera – Electrophysics Hotshot HD-S • 640x480 IR imager – +/-2c accuracy spec - -20c-350c calibrated Test Bench 3
  4. 4. Increase Server Reliability ◦ • LPe12002 operates 27 F cooler than QLE2562 • Why is this significant? • Reduces heat stress • Reduces thermal cycles • Benefits of cooler operation: • Increase server reliability • Improve SAN availability ° 150 140 130 ◦Fahrenheit 120 Max = 121○ F Max = 148○ F 110 100 90 Emulex LPe12002 80 QLogic QLE2562 4
  5. 5. More Reasons To Choose Emulex… ◦ Emulex I/O controller operates 12 F cooler than QLogic – even without a heat sink! ° 150 Max = 136○ F 140 Max = 148○ F 130 ◦Fahrenheit 120 110 100 90 Emulex LPe12002 80 QLogic QLE2562 Emulex solutions are designed to work in broad range of server environments without : – Sacrificing reliability – Impacting performance – Jeopardizing SAN availability 5
  6. 6. RAS Advantages of Emulex 8Gb/s HBAs Heat stressed components generally exhibit lower reliability and system performance impacting: – Device reliability – System availability – Network serviceability Emulex 8Gb/s I/O controllerA operates cooler than QLogic’s 8Gb/s I/O controller, resulting in 166% greater MTBF performanceB A: Junction Temperature B: Calculation based on standard Bellcore methodology and assumes same die size 6
  7. 7. Emulex - The Choice is Clear So which HBA would data center administrators prefer to have operating in their servers? OR The Cooler Running HBA The Hotter Running HBA Emulex LPe12002 QLogic QLE2562 Emulex HBAs provide the greatest level of reliability and SAN availability by operating cooler than the competition in a broader range of server environments 7
  8. 8. Competitive Overview – QLogic Cooler Operation & Better Efficiency and MTBF The LPe12000 family with passive cooling provides superior reliability – Optimize server performance I/O Controller Temperature Performance – Improve SAN availability 160 Emulex has superior MTBF hours 150 – Emulex’s 10 Million vs QLogic’s 7.6 million 140 Temperature (F) Emulex LPe12002 operates 27º F cooler 130 than QLogic QLE2562 running identical workloads 120 Emulex LPe12002 110 – Maximizes server performance – Increases server reliability 100 Emulex QLogic – Reduces maintenance costs – Improves SAN availability 8
  9. 9. Emulex LP21000 Family vs QLogic QLE8042 Family 9
  10. 10. Emulex LP21000 Family – A Better Solution Leverages similar passive cooling technology as the LPe12000 family Emulex LP21002 provides greater reliability and energy savings than QLogic’s QL8042 FCoE CNA – Lower Power Consumption • 19% less power than QLogic QLE8042 – Higher Reliability • Operate 28% cooler than QLogic QLE8042 ° 190 180 170 ○ Max = 148 F 160 ◦Fahrenheit 150 140 130 Max = 190○ F 120 110 100 90 Emulex LP21002 80 QLogic QLE8042 10
  11. 11. Emulex - The Choice is Clear So which CNA would data center administrators prefer to have operating in their servers? OR The Cooler Running CNA The Hotter Running CNA Emulex LP21002 QLogic QLE8042 Emulex CNAs provide the greatest level of reliability and SAN availability by operating cooler than the competition in a broader range of server environments. 11
  12. 12. Emulex Is the Reliability Leader While competitors talk about reliability, Emulex delivers it More Data center and IT professionals rely on Emulex than any other brand to ensure reliable server to SAN A connectivity March 2009 Survey Emulex 8Gb/s Fibre Channel and FCoE CNA solutions are the clear choice for: – Unrivaled performance – Uncompromised reliability 12
