Hi there, I want to replace some servers (SOHO, Mail-, web-, Infrastructure, X86_64, all with CentOS) with ARM-Servers. I've a /home-Server with Odroid XU4 (Cloudshell) with Fedora running fine.
Are there other ARM-Devices running CentOS easy?
there are -no- ARMv7 grade server hardware available, there are single board units, none of which are capable of running infrastructure services for any reasonable performance. the cubietruck seems the most 'capable' but still falls well short of reasonable performance.
There are however ARMv8 based server's that are available, the APM Mustang class of boards are well supported in CentOS Linux 7 and are perhaps the most widely available.
this does however take into consideration my own interpretation of what might be considered 'reasonable performance'.
ARMv7 server grade hardware does exist. It wasn't so long ago that I was helping the guys at Boston get RedSleeve 6 getting up and running on their Viridis servers:

The biggest limitation with 32-bit ARM hardware isn't the CPU performance but the 4GB RAM limit, and the vast majority of devices comes with far, far less than 4GB; 512MB-1GB is much more typical. If your workload fits within that memory envelope, I find the performance isn't too bad for a variety of workloads.
