Transcript

  • 1. Replacing  your  So0ware?  Time  to  consider  your  hardware.   Nathan  Kroenert   Frontline  Systems  Australia  and  Melbourne  Solaris  Users  Group  ‘President’   The most comprehensive Oracle applications & technology content under one roof
  • 2. Agenda  •  The  evolu@on  of  SoBware  •  The  progression  of  hardware  •  The  ‘Exclusive  Convergence’  of  systems  •  Improvements  in  interconnects  •  Changes  in  APIs  and  interchange   methodologies   The most comprehensive Oracle applications & technology content under one roof
  • 3. Who  am  I?  •  Nathan  Kroenert  •  Frontline  Systems  Na@onal  Service  Delivery   Manager  •  Melbourne  Solaris  and  Oracle  Systems  Users   Group  President  •  8  Years  @  Sun:  Educa@on,  Tier  4  support,   PreSales  •  4  years  @  ANZ  •  Considerable  @me  spent  on  Performance.   The most comprehensive Oracle applications & technology content under one roof
  • 4. The most comprehensive Oracle applications & technology content under one roof
  • 5. The  Evolu@on  of  SoBware  •  The  @mes  the  are  a  changin  (Thanks,  Bob)  •  Much  less  about  what  the  vendor  gives  you  •  Much  more  about  what  the  business  wants   the  applica@on  to  do,  with  a  range  of  op@ons  •  Influenced  by  open  development  •  Influenced  by  compe@@on  •  Modularity  is  prolifera@ng   The most comprehensive Oracle applications & technology content under one roof
  • 6. The  Evolu@on  of  SoBware  •  Many  systems  being  replaced  are  from  the   monolithic  era.  •  New  systems  are  typically  much  more  externally   dependent  rather  then  request  /  result    •  Custom  Binaries  in  C  have  moved  more  and  more   to  layered  architectures,  J2EE,  Web+App+DB,   message  busses  and  more  •  Ruby,  Python,  JAVA,  C#  -­‐  all  have  considerable   system  level  impact   The most comprehensive Oracle applications & technology content under one roof
  • 7. Assump@ons  of  New  SoBware  •  New  SoBware  oBen  makes  New  System   assump@ons  •  Much  of  the  new  soBware  out  there  expects     –  Huge  amounts  of  memory   –  Many  threads   –  Very  low  latency  interconnects   –  CPUs  with  hardware  support  for  many  func@ons   The most comprehensive Oracle applications & technology content under one roof
  • 8. Solu@on  when  SoBware  and  Hardware   are  not  a  good  match?   The most comprehensive Oracle applications & technology content under one roof
  • 9. The  Progression  of  Hardware  •  CPU’s  no  longer  gedng  drama@cally  faster  in   a  straight  line  –  but  are  gedng  WIDER  •  CPUs  gedng  more  capability  in  silicone  •  Memory  System  bandwidth  increasing  –   though  latency  is  not  improving  •  Memory  density  increasing,  but  also  not   progressing  nearly  as  fast  as  applica@ons  can   use  it     The most comprehensive Oracle applications & technology content under one roof
  • 10. The  Progression  of  Hardware  •  Interconnects  have  improved  •  Busses  and  loops  have  given  way  to  fabrics   (SAS,  PCI-­‐E,  Infiniband)  •  ‘Commodity’  is  a  commodity  term.    •  Focus  is  oBen  on  CapEx  –  though  oBen  at  the   expense  of  OpEx.     The most comprehensive Oracle applications & technology content under one roof
  • 11. Interconnects   The most comprehensive Oracle applications & technology content under one roof
  • 12. Interconnects  and  caching  •  10Gbe  Now,  40  and  100GbE  coming  soon  •  QDR  Infiniband  here  now  (40Gbps),  EDR  and   FDR  already  releasing  •  FLASH  (Ah  aaaaaah)  •  SoBware  gedng  much  smarter  about  using   @ers  WITHOUT  external  assistance  (eg:  11gR2   using  flash  directly)   The most comprehensive Oracle applications & technology content under one roof
  • 13. Hypervisors  are  cool,  right?  •  To  V  or  not  to  V!  •  Why  do  we  Virtualize?  •  Regularly  required  because  ‘the  hardware  is  too   big’,  and  because  commodity  hardware  lacks   many  of  the  safeguards  of  Enterprise  •  The  an@thesis  of  what  makes  sense  in  ‘large   systems’.  S@ll  has  value  (eg:  Availability)  •  Many  and  varied:  Which  should  you  use?  When   should  you  use  them?   The most comprehensive Oracle applications & technology content under one roof
  • 14. Clawing  back  the  Datacentre  •  Racks  of  old  systems  can  be  consolidated  into   RU’s  of  space  •  Do  in  200W  what  previously  took  2000W  •  Legacy  support  costs  can  be  crippling  •  Message  passing  speed  of  older  plamorms   (using  PCI,  PCI-­‐X)  are  slower.  Today  is  all  about   message  speed  •  Increased  reliability:  ECC,  Checksums,  etc.   The most comprehensive Oracle applications & technology content under one roof
  • 15. Exclusive  Convergence  vs  Solu@ons  •  Many  vendors  have  their  own  ‘convergence’  •  Most  are  claimed  to  be  designed  with  a  ‘system’   approach  in  mind,  and  are  pitched  as  a   ‘architected  solu@on’  •  Many  solu@ons  are  incompa@ble  and  force  you   into  that  vendors  idea  how  it  should  be  done.    •  The  Oracle  value  is  that  you  can  use  best  of  breed   components,  OR  allow  Oracle  to  provide  the   en@re  stack.   The most comprehensive Oracle applications & technology content under one roof
  • 16. COST  •  New  hardware  delivers  more  bang  for  buck  •  Oracle  Core  Factor  -­‐  .25  for  T3,  .5  for  M-­‐series   and  X86,  1  for  P-­‐series,  and  Itanium  largely   irrelevant!  ;)   The most comprehensive Oracle applications & technology content under one roof
  • 17. Lifecycle  WIN  vs  Expenditure  FAIL  •  Infrastructure  is  typically  only  a  small  component   of  an  IT  project.    •  It’s  typically  the  one  chance  for  a    to  change  it’s   deployment  architecture  and  to  get  onto  the   latest  and  greatest  hardware  •  Provides  the  opportunity  to  build  the  right  sized   infrastructure  rather  than  guessing  •  CPU  capabili@es  will  be  tracking  soBware   developments.  Eg:  DB  specific  instruc@ons   The most comprehensive Oracle applications & technology content under one roof
  • 18. It’s  great  news:    Your  applica@on  can  be  fast.   The most comprehensive Oracle applications & technology content under one roof
  • 19. Get  the  MOST  from  your  SoBware  •  Understanding  your  soBware  helps  architect  a   system  to  suit  it  •  Select  the  right  CPU  architecture  type  •  Select  the  right  memory  architecture  •  Balance  I/O  •  Use  teiring  intelligently,  not  just  because  you   can  •  Agility  in  deployment:  Virtual  versus  Physical   The most comprehensive Oracle applications & technology content under one roof
  • 20. Summary:  •  Running  new  soBware  on  previous  genera@on   hardware  is  fraught  with  danger  •  Many  soBware  assump@ons  don’t  stack  up  on  old   hardware  •  Many  applica@ons  actually  require  instruc@on  set   support  to  run  at  their  best  •  To  get  the  most  from  your  soBware  applica@ons,   the  best  start  you  can  give  them  is  a  fresh  batch   of  @n.   The most comprehensive Oracle applications & technology content under one roof
