Exadata is a combined hardware and software platform that includes scale-out Intel x86-64 compute and storage servers, RoCE or InfiniBand networking, persistent memory (PMEM), NVMe flash, and specialized software.

Exadata was introduced in 2008, and, since October 2015, is available either as an on-premises product or via the Oracle Cloud as a subscription service, known as the Exadata Cloud Service.[2] Oracle databases deployed in the Exadata Cloud Service are 100% compatible with databases deployed on Exadata on-premises, which enables 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.

Use cases

Exadata is designed to run Oracle Database workloads, such as an OLTP application running simultaneously with Analytics processing. Historically, specialized database computing platforms were designed for a particular workload, such as Data Warehousing, and poor or unusable for other workloads, such as OLTP. Exadata allows mixed workloads to share system resources fairly with resource management features allowing prioritized allocation, such as always favoring workloads servicing interactive users over reporting and batch, even if they are accessing the same data. Long running requests, characterized by Data Warehouses, reports, batch jobs and Analytics, are reputed to run many times faster compared to a conventional, non-Exadata database server.[3][4]

gollark: Unfortunately, this isn't one of those poorly blurred things where you can theoretically reconstruct it a bit.
gollark: No, I didn't.
gollark: This is sarcastic. It would not be useful.
gollark: Yes, I can really see the value of mining in your own browser with some indirection.
gollark: Mine mostly just doesn't explicitly set background colors, so you can darktheme it if desired.
