> I'm afraid nobody will build a 100PB cluster with 1T drives. That's just absurd Check the archives for the panoply of absurdity that I’ve encountered ;) > So, the sharp increase of per-device capacity has to be taken into account. Specifically as the same development is happening with SSDs. There is no way around 100TB drives in the near future and a system like ceph is either able to handle that or will die Agreed. I expect 122TB QLC in 1H2025. With NVMe and PCI-e Gen 5 one might experiment with slicing each into two OSDs. But for archival and object workloads latency usually isn’t so big a deal, so we may increasingly see a strategy adapted to the workloads. > 10 higher aggregated sustained IOP/s performance compared with a similarly sized ceph cluster > But not, I suspect, nearly as many tentacles. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
