1 System Requirements and Limitations
WARNING:
Oracle Linux 7 is now in Extended Support. See Oracle Linux Extended Support and Oracle Open Source Support Policies for more information.
Migrate applications and data to Oracle Linux 8 or Oracle Linux 9 as soon as possible.
You can install Oracle Linux 7.9 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 specific 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.
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 7.9. 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 in the
table are estimates, which 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, while the actual achievable values might be lower
than these values, depending on the hardware and kernel version
that is used.
| File System Type | Maximum File Size | Maximum File System Size |
|---|---|---|

The limits for the ext4 file system that are
described in the table are higher than the recommended limits
and might prove unstable. If you are working with systems on
which you intend to work toward 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.
