Chapter 1 System Requirements and Limitations
You can install Oracle Linux 7.8 on x86_64 systems that have up to 2048 logical CPUs and 64 TB of memory. The theoretical upper limit is 5120 logical CPUs and 64 TB of memory; however, 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 that is required for installation is 1GB, a minimum of 5 GB is recommended.
1.1 File System, Storage, and Address Space Limitations
The following table describes the maximum file size and maximum
file system size for the btrfs,
ext4, and xfs file systems
in Oracle Linux 7.8. File system limitations are affected by kernel
versions and features, as well as the architecture of the system
on which Oracle Linux is installed. The values that are depicted here
are estimates that are based on known variables that might
affect the maximum theoretical value that can be achieved. Note
that the theoretical values might be higher than those depicted
here, and the actual achievable values might be lower than these
values, depending on the hardware and the kernel version that is
used.

The limits for the ext4 file system described
here are higher than recommended limits and might prove
unstable. If you are working with systems on which you intend to
work towards using higher file system sizes or file sizes, it is
recommended that you use either the Btrfs or XFS file system.
The maximum supported size for a bootable logical unit number (LUN) is 50 TB. GPT and UEFI support are required for LUNs that are larger than 2 TB.
The maximum size of the address space that is available to each process is 128 TB.
