We will use the cluster only for backup large amount of data, we will love to have much more performance but in that case the price will rise way above the budget. And the question why we choose to use ceph rather than more classic system are the migration of the data when the hardware will reach end of life. The plan is to use the capability of ceph to migrate by himself the data from old to new hardware. So short answer : no enough money ;-) ;-) Regards. -- Albert SHIH 🦫 🐸 France Heure locale/Local time: sam. 18 nov. 2023 09:19:03 CET _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
