Chapter 1 System Requirements and Limits
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.
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. File system limitations are affected by kernel versions
and features, and by the architecture of the system where Oracle Linux
is installed. The values depicted here are estimates based on
the known variables that might affect the maximum theoretical
value that can be achieved. The theoretical values might be
higher than those depicted here, and the actual achievable
values might be below the values that are shown, depending on
hardware and the kernel version used.

The limits for the ext4 file system that are
described here are higher than recommended and might prove
unstable. If you plan to work with systems where you are 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.
