Chapter 2. Architectures
Chapter 2. Architectures Red Hat Enterprise Linux 7 is available on the following architectures: [1] 64-bit AMD 64-bit Intel IBM POWER7+ (big endian) IBM POWER8 (big endian) [2] IBM POWER8 (little endian) [3] IBM POWER9 (little endian) [4] [5] 64-bit IBM Z [4] [6] 64-bit ARM [4] The Red Hat Enterprise Linux 7.9 is distributed with the kernel version 3.10.0-1160, which provides support for the following architectures: 64-bit AMD 64-bit Intel IBM POWER7+ (big endian) IBM POWER8 (big endian) IBM POWER8 (little endian) 64-bit IBM Z (kernel version 3.10) Note The IBM POWER9 (little endian) and 64-bit IBM Z - Structure A architectures was retired on May 31, 2021. The 64-bit ARM architecture was retired on August 6, 2020, as per the RHEL Life Cycle . [1] Note that the Red Hat Enterprise Linux 7 installation is supported only on 64-bit hardware. Red Hat Enterprise Linux 7 is able to run 32-bit operating systems, including versions of Red Hat Enterprise Linux, as virtual machines. [2] Red Hat Enterprise Linux 7 POWER8 (big endian) are currently supported as KVM guests on Red Hat Enterprise Linux 7 POWER8 systems that run the KVM hypervisor, and on PowerVM. [3] Red Hat Enterprise Linux 7 POWER8 (little endian) is currently supported as a KVM guest on Red Hat Enterprise Linux 7 POWER8 systems that run the KVM hypervisor, and on PowerVM. In addition, Red Hat Enterprise Linux 7 POWER8 (little endian) guests are supported on Red Hat Enterprise Linux 7 POWER9 systems that run the KVM hypervisor in POWER8-compatibility mode on version 4.14 kernel using the kernel-alt package. [4] This architecture is supported with the kernel version 4.14, provided by the kernel-alt packages. For details, see the Red Hat Enterprise Linux 7.5 Release Notes . [5] Red Hat Enterprise Linux 7 POWER9 (little endian) is currently supported as a KVM guest on Red Hat Enterprise Linux 7 POWER9 systems that run the KVM hypervisor on version 4.14 kernel using the kernel-alt package, and on PowerVM. [6] Red Hat Enterprise Linux 7 for IBM Z (both the 3.10 kernel version and the 4.14 kernel version) is currently supported as a KVM guest on Red Hat Enterprise Linux 7 for IBM Z hosts that run the KVM hypervisor on version 4.14 kernel using the kernel-alt package.
