X11m

Migrating from Exadata X7 to X11M is not a simple hardware swap — it is a generational architectural shift. The X11M introduces RoCE (RDMA over Converged Ethernet) replacing InfiniBand, PCIe Gen5 NVMe replacing earlier NVMe tiers, and a new compute architecture with AMD EPYC processors. This article provides an in-depth, end-to-end playbook for architects and senior DBAs planning this migration. Reference Environment All commands in this article use the following concrete hostnames and roles. Every code block identifies which server and user account the command runs from. ...

The Exadata X11M platform separates database compute and storage cells connected via an RDMA-capable RoCE fabric. This page summarizes hardware variants and provides practical command-line examples for common administration, troubleshooting and monitoring tasks. Architecture Overview Database Servers (Compute) These servers run the database and client-facing workloads.
