The '''Oracle Exadata''' '''Database Machine''' ('''Exadata'''<ref name=":30">{{Cite web |last=Various |date=June 2023 |title=Oracle Exadata Database Machine X10M |url=https://www.oracle.com/a/ocom/docs/engineered-systems/exadata/exadata-x8m-2x10m-ds.pdf |titleurl-status=Oraclelive Exadata Database Machine X8M|access-2|last=Various|date=SeptemberJune 22, 2023 2019|website=oracle.com|access-date=September 19, 2019}}</ref>) is a computing platform optimized for running [[Oracle Database]]s.

Exadata is a combined hardware and software platform that includes [[Scale out|scale-out]] [[x86-64]] compute and storage servers, [[RDMA over Converged Ethernet|RoCE]] or [[InfiniBand]] networking, RDMA-addressable memory acceleration, [[NVM Express|NVMe]] flash, and specialized software.<ref name=":0">{{Cite web|last=Pedregal-Martin|first=Cristobal|title=Exadata: Why and What|url=https://blogs.oracle.com/exadata/exadata-why-and-what|url-status=live}}</ref>

Exadata was introduced in 2008 for on-premises deployment, and, since October 2015, via the [[Oracle Cloud]] as a subscription service, known as the ''Exadata Database Service''.<ref>{{Cite book|title=Oracle Database Exadata Cloud Service: A Beginner's Guide|last=Spendolini|first=Brian|publisher=Oracle Press|year=2019|isbn=978-1260120875|___location=Amazon.com}}</ref> Exadata Cloud@Customer is an on-premises implementation of Exadata Database Service, available since 2017. Oracle databases deployed in the Exadata Database Service or Exadata Cloud@Customer are 100% compatible with databases deployed on Exadata on-premises, enabling customers to transition to the Oracle Cloud with no application changes. Oracle Corporation manages this service, including hardware, network, Linux software and Exadata software, while customers have complete ownership of their databases.

==End-of-supportSupport Policy==

As the platform has been around since 2008, Oracle has published information related to the end-of-support for older Exadata generations. In Oracle's published document titled ''Oracle Hardware and Systems Support Policies'',<ref>{{Cite web|url=https://www.oracle.com/us/support/library/hardware-systems-support-policies-069182.pdf|title=Oracle Hardware and Systems Support Policies|access-date=March 5, 2021}}</ref> they mention "After five years from last ship date, replacement parts may not be available and/or the response times for sending replacement parts may be delayed." To look up the "last ship date" of a particular Oracle Exadata generation, Oracle published a document titled ''Oracle Exadata - A guide for decision makers''.<ref>{{Cite web|url=https://www.oracle.com/a/otn/docs/exadata-decision-maker-guide.pdf|title=Oracle Exadata - A guide for decision makers|access-date=December 1, 2020}}</ref>
