Oracle Engineered Systems Round Table – Pittsburgh – March 11th

Earlier this week, I attended the Oracle Engineered Systems Round Table in Pittsburgh. I attended (what I think was) the first such event in Columbus in 2011 and it was great to see how companies have grown their Exadata platform, matured their support and have brought quantifiable business benefits.

Some general insights that I had noted were:

  • Exadata had proven to be the “gold standard” as a technical solution for business needing extreme performance from their RDBMS.
    • Other solutions had to prove they were technologically better (not just cheaper).
  • Most companies had implemented Exadata, liked how it performed and expanded its footprint and support teams as their business grew.
    • One customer in particular had 1 Exadata machine when the first round table was held in 2011.
    • In 2014, they have 10 Exadata machines and have been able to retire 100+ servers.
  • Most companies emphasized that DBA, UNIX, network and storage teams had to strongly collaborate.
    • Some had dedicated Engineered Systems Administration teams.
  • Network expertise was a bit of a blind spot for everyone; some mentioned Linux expertise.
  • 67% of all migrations do not go as planned.
  • Most companies used NetBackup/Data Domain/both to back up their Exadata databases.
    • They saw similar throughput/performance to us.
    • One customer used ZFS and they reduced their backup by 24x.
  • Bad code is still bad code. Who knew?
  • No-one had installed Exadata, nor done a major upgrade without either ACS or Platinum Support.
    • In previous round tables, some customers had mentioned doing it themselves and running into big problems.
    • Upgrades are meant to becoming simpler process-wise, but their scope is becoming more complex.
    • Perhaps it’s better for everyone that customers continue to learn on Oracle for upgrades – and Platinum Support is free, as long as you don’t have a V1 or V2 machine.
  • A quarter-rack – proportionately, not just in absolute terms – provides very limited amounts of “safely usable space”
    • The failure group – which is subtracted from the size of storage in the calculation – is 1/3rd of the total raw storage of the machine.
    • In a half-rack, it is 1/7th; in a full-rack, it’s 1/14th.
