1 System Requirements and Limits
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 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.
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 may affect the maximum theoretical
value that can be achieved. The theoretical values may be higher
than those depicted here, and the actual achievable values may
be below the values shown depending on hardware and the kernel
version used.
| File System Type | Maximum File Size | Maximum File System Size |
|---|---|---|

The limits described here for ext4 are higher
than recommended and may prove unstable. If you intend to work
with systems where you are working toward higher file system
sizes or file sizes, it is recommended that you use either
btrfs or XFS.
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.
