I assume the limits are those that linux imposes. iops are the limits. One 20TB has 100 iops and 4x5TB have 400 iops. 400 iops serves more clients that 100 iops. You decide what you need/want to have. > -----Original Message----- > From: huxiaoyu@xxxxxxxxxxxx <huxiaoyu@xxxxxxxxxxxx> > Sent: 12 March 2021 18:10 > To: ceph-users <ceph-users@xxxxxxx> > Subject: How big an OSD disk could be? > > Dear cephers, > > Just wonder how big an OSD disk could be?
