Hi, I am currently defining a storage architecture based on ceph, and i wish to know if i don't misunderstood some stuffs.
So, i plan to deploy for each HDD of each servers as much as OSD as free harddrive, each OSD will be inside a LXC container. Then, i wish to turn the server itself as a rbd client for objects created in the pools, i wish also to have a SSD to activate caching (and also store osd logs as well) The idea behind is to create CRUSH rules which will maintain a set of object within a couple of servers connected to the same pair of switch in order to have the best proximity between where i store the object and where i use them (i don't bother having a very high insurance to not loose data if my whole rack powerdown) Am i already on the wrong track ? Is there a way to guaranty proximity of data with ceph whitout making twisted configuration as i am ready to do ? Thks in advance, Regards -- *Guillaume Comte* 06 25 85 02 02 | guillaume.co...@blade-group.com <guilla...@blade-group.com> 90 avenue des Ternes, 75 017 Paris
