Red Hat Enterprise Linux for ARM is here

Red hat logo

We've seen the server arena go through a stage where x86-based architectures (both IA-32 and AMD64) have dominated with a firm hand. But in recent years ARMDue to its performance and energy efficiency, a gap is opening in mobile devices but also in the field of microservers or small low-consumption servers for certain companies that do not require powerful machines. That is why many operating system developers have seen a good opportunity to launch versions with ARM support of their systems for servers, as is the case of Microsoft with its Windows Server ...

Now also the giant Red Hat it joins having a powerful operating system, in this case based on Linux, to run on this type of ARM-based machines. That is, RHEL (Red Hat Enterprise Linux) is already available for ARM, specifically the RHEL 7.4 version that comes with a multitude of software whose packages have been updated and specific for this platform and also the Linux 4.11 kernel, a fairly current version of the core of Torvalds & Company.

This distro is therefore optimized for SoC (System on a Chip) based on 64-bit ARM that will make up the servers we are talking about. This is not a complete novelty, we have already seen a multitude of distributions such as Ubuntu, openSUSE, etc., that work well with ARM architectures or even for the Raspberry Pi itself, which as you know is based on ARM as well. But the novelty here is that it is a server operating system.

And what do these types of servers contribute? Well, when we have x86 chips we talk about consumption around 90w or more, although it is true that their performance is very high. But when we base the servers on ARM, the consumptions go down to 10 - 45w, that is, between 9 and 2 times lower than with Intel and AMD chips. However, the performance is quite acceptable, it is not at all 9 times lower than in the case of x86 thanks to the good consumption / performance ratio they have.
