Disk and file systems: There are four hard disks in each database server of a 2-socket Oracle Exadata. There are eight hard disks in each database server of a 8-socket Oracle Exadata Database Machine, or, starting with Oracle Exadata X7-8, two flash accelerator PCIe cards, 6.4 TB each.
The disk partitions on a database server in Oracle Exadata are configured with two file systems, and a swap partition. The root (/) file system is 30 GB, the
/u01
file system is 100 GB, and the swap partition is 24 GB. -
Services: Nonessential services are disabled on database servers. Enabled services include SSH for remote access, and after deployment, listeners.
