SoftBank Mobile Replaced Teradata with Exadata

Quite interesting reference project for Oracle Exadata completed a year ago.

Just excerpts:

  • improved data warehouse performance by 8X
  • replaced 36 Teradata racks with just three Oracle Exadata racks
  • 150% increase in storage capacity
  • reduced operational costs by more than half
  • accelerated analysis of billions of call records by more than 300%(“it was taking us 25 hours to analyze the data log each day”)
  • electricity saving by 9.68x at peak load (Based upon publicly available data sheets, 36 Teradata 2650 consume 255.6kW of electricity compared to 26.4kW for three full-rack Exadata Database Machines).

PS. numbers really look AMAZING, but what is more interesting – how is this customer now ? 😉

  1. Hi Apex,

    Thanks for comment!
    and for providing link to based blog 😉

    It’s always invaluable to hear from competitor’s Expert!

    Sorry for my stupid questions, because I’m not a Taradata Expert:
    1) WHY old good Teradata customer decided to move to DWH architecture with Oracle Exadata ?
    may be Oracle payed for that ? 😉
    2) WHY they didn’t replaced 36 TD Racks with just 2 new TD Racks(mentioned in your post) buying HW
    and moving old licenses to new HW – “free, just through software” ?
    3) WHY the mentioned Moore’s law didn’t helped Teradata to stay there ?
    so the Moore’s law, which works fine for Intel-based hardware used in Oracle Exadata,
    in fact doesn’t work for hardware used in Teradata ?


    PS1: just my replay to “Teradata is indeed a humble leader” –
    modesty – the way into the unknown ?

    PS2: I understand cases when customers move from Oracle to Teradata(I’m really not an Oracle crazy fun ;)),
    but I really don’t understand cases when customers move from Teradata to Exadata…

    BTW, are there any cases when customers moves from Exadata(not just Oracle RDBMS) to Teradata ?

  2. It’s more than year from the date of your question, but I think it’s still worth to give an answer:)

    1) I believe it was a mix of policy and a reasonable attempt to cut a cost of support through unifying of existing infrastructure. And I definitely wouldn’t blame management of SoftBank in a bribery.
    2) Because they didn’t want to run with Teradata, the sentence was known in advance. BTW, there is no such thing like “moving licenses”, if one wants to go with Teradata he should purchase a whole appliance (not always, but in the most cases). Of cause if you already have old appliance you can receive a rebate for the new one, but this is another story.
    3) Because it (Moore’s law) doesn’t matter. Once again, the reason of replacement wasn’t based on the technical advantages of Exadata over Teradata, there is no any evidence of these advantages. So, back to the Moore and his law – it works for both of the vendors, it works just by itself, but due to decision was made based on the causes other than technical ones, the question does not have any sense.

    >modesty – the way into the unknown ?

    Often the policies of company are largely depend on the person who leads the company. For someone it’s OK to lie to customers, sell them unworkable software, cheat with the version’s numbers and so on. For others it’s unacceptable.

    >but I really don’t understand cases when customers move from Teradata to Exadata…

    Why not? They could really save a money because of good discount from Oracle, because of unifying and consolidation of infrastructure, because they need some unique Oracle’s functionality and so on and so forth.

    >BTW, are there any cases when customers moves from Exadata(not just Oracle RDBMS) to Teradata ?

    I think it’s too early to look for these cases, Exadata is too young compare to Teradata.

    • Apex,
      I understand your position in this comment and support it mostly,
      because of possible ‘mix of policy and… to cut a cost…through unifying of existing infrastructure”
      I don’t want to dive into demagogy, so lets allow time do it’s judgment 😉
