1.1 System Requirements

Oracle Linux 7 includes both the Unbreakable Enterprise Kernel (UEK) and Red Hat Compatible Kernel (RHCK). You can install Oracle Linux 7 on x86-64 systems with up to 2048 logical CPUs and 64 TB of memory. The theoretical upper limit is 5120 logical CPUs and 64 TB of memory, but Oracle has not tested this configuration. A minimum of 2 logical CPUs and 1 GB of memory per logical CPU is recommended. Although the minimum disk space required for installation is 1GB, a minimum of 5 GB is recommended.

If your system supports UEFI mode and you plan to boot and install Oracle Linux 7 in this mode, make sure that the target disk uses GPT (GUID Partition Table), as some UEFI firmwares do not allow UEFI/MBR boot.

For additional details about system requirements and any known installation issues, see the release notes for your Oracle Linux 7 release at https://docs.oracle.com/cd/E52668_01/index.html.

For information about x86-based servers that are certified for Oracle Linux with UEK, see the Hardware Certification List for Oracle Linux and Oracle VM at https://linux.oracle.com/hardware-certifications.

For UEK system requirements and known issues, see the documentation for your UEK release at https://docs.oracle.com/cd/E93554_01/index.html.
