Hi, all. I want to use ceph instead of HDFS in big data analysis senario, does ceph have some potential problems when the cluster becoming big? say 100PB or 500PB? As far I know, there are some cons: 1. no short circuit read, so we need fast network say 10G or better 50G? 2. not exactly du, but it is acceptable for applications. 3. ceph can't handle slow disk as HDFS does for example heged read or write. Is that right? or there are many other cons? Thanks in advance. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
