The most significant differentiator between Exadata and traditional storage architectures is a feature called <strong>Smart Scan</strong> (also known as Cell Offload Processing).</p> <p>Instead of treating storage as dumb disks that just serve blocks to the database, Exadata pushes SQL processing down to the storage tier. This article explains how Smart Scan works, how to verify it, and how to control its behaviour for testing.</p> https://ora-base.com/exadata/exadata-command-line-utilities/ Sat, 21 Feb 2026 00:00:00 +0000 https://ora-base.com/exadata/exadata-command-line-utilities/ <p>The Exadata X11M platform separates database compute and storage cells connected via an RDMA-capable RoCE fabric.
