Transcript

  • 1. SUN SPARC SYSTEMS: HISTORIC VIEW
    • Pavel Anni
        • Sun Microsystems
  • 2. Executive Summary
    • According to historical data, typical life expectancy of Sun SPARC systems family is 6.5-7.5 years
    • Systems families usually have 1.5 years overlap to allow customers make a smooth transition
    • Systems have processor speedbumps over their lifetime; starting from Sun Fire family (2001) it is possible to have processor with different speeds in one system
    • Technologies used in the systems families evolve over time, becoming more and more mature
  • 3. Industry Leading ROI 1996 1998 2000 2002 2004 2006 2008 2010 2012 UltraSPARC I, UltraSPARC II UltraSPARC III, IV, IV+ SPARC64 VI, VII } 6 years 7 months } 7 years 9 months ~ 6 - 7 years
  • 4. Systems Transition Periods 1996 1998 2000 2002 2004 2006 2008 2010 2012 UltraSPARC I, UltraSPARC II UltraSPARC III, IV, IV+ SPARC64 VI, VII 1.5 years 1.5 years Consistent transition period
  • 5. Domains story 1996 1998 2000 2002 2004 2006 2008 2010 2012
    • E10K
    • Since 1997
    • Up to 16 domains per system
    • Granularity: 4 CPU + I/O (together only)
    • Dynamic Reconfiguration
    • Smallest system with domaining: E10K, 64-way
    • Sun Fire 25K
    • Since 2001
    • Up to 18 domains per system
    • Granularity: 4 CPU and/or I/O board
    • Dynamic Reconfiguration
    • Smallest system with domaining: SF 4800, 12-way
    • SPARC Enterprise
    • Since 2007
    • Up to 24 domains per system
    • Granularity: 1 CPU, ¼ I/O board, 8 DIMMs
    • Dynamic Reconfiguration
    • Smallest system with domaining: M4000, 4-way
    Better granularity, More domains, Domains go mid-range Even better granularity, Even more domains, Domains go entry-level SPARC
  • 6. RAS story 1996 1998 2000 2002 2004 2006 2008 2010 2012
    • E10K
    • No single point of failure
    • POST and Automatic Reconfiguration
    • Redundant systems boards, power supplies
    • Hot-swap system boards, control boards, power supplies, disk drives
    • ECC and parity protection
    • Sun Fire 25K (in addition to the above)
    • Auto Diagnosis and Recovery
    • More ECC protection
    • Survive more component failures
    • Redundant system controllers and clocks
    • Redundant and hot-swappable PCI-X cards
    • Reconfigurable Logic Centerplane
    • Field Replaceble Unit ID
    • SPARC Enterprise (in addition to the above)
    • Reduced component count
    • CPU Instruction Retry
    • Memory Patrol, Extended-ECC and Mirroring
    • End-to-end ECC
    • Tight integration with Solaris 10 FMA
    • Chip level fault detection
    • Automatic Dynamic Reconfiguration
    • Preventive maintenance
