System Requirements Changes from 2024.6 CentOS7 to 2025.1 Almalinux
Environment
- N-able N-central
General System Requirement Changes
| Current | New | |
|---|---|---|
| Processor | Server class x86_64 CPUs manufactured by Intel or AMD (i.e. Xeon or EPYC). Please refer to the Red Hat Hardware Ecosystem for further details. | Server class x86_64 CPUs manufactured by Intel or AMD (i.e. Xeon or EPYC). |
| Operating System | You do not need to install a separate Operating System to run N-able N-central. The N-able N-central ISO includes a modified version of CentOS 7, based on the upstream Red Hat Enterprise Linux 7. |
You do not need to install a separate Operating System to run N-able N-central. The N-able N-central ISO comes package with the N-central powered by AlmaLinux OS |
| Physical Hardware |
The physical server used to install N-able N-central in a bare metal environment must be certified to run Red Hat Enterprise Linux 7.9 (x64) by Red Hat, or the hardware vendor, without any additional drivers. Please check the Red Hat Hardware Ecosystem for details. Server Grade hard drives connected to a RAID controller with a Battery/Capacitor Backed Cache are Required. Examples include 10K+ RPM SCSI or SAS drives, Enterprise Grade SSDs or NVMes for bare metal and virtualized hosts, or a Fibre Channel connected SAN with Enterprise Grade hard drives for virtualized hosts (Fibre Channel cards can be used for bare metal if they are configured in the pre-boot environment and do NOT require vendor-provided drivers). Although Desktop Hard Drives will work with the Operating System, they do not meet the minimum throughput required for the back-end Database of N-able N-central. |
