Ceph was designed to run on commodity hardware, which makes building and maintaining petabyte-scale data clusters economically feasible. When planning out your cluster hardware, you have to balance several considerations, including failure domains and potential performance issues. However, the performance and stability of a production cluster are tightly related to the integration of Linux kernel, Linux distribution, hardware configurations, and Ceph. Enterprise storage is mission-critical. Untuned integration may embed inherent stability and performance issues.
Tuning Ceph, Linux kernel, and hardware configurations to get stable and outstanding performance requires experienced engineers and much of the time.
Ambedded devotes professional resources on the Ceph appliance product for giving customers reliable products. Ambedded tunes and verifies every software upgrade before releasing it.
