Hi, I'm designing my infraestructure. I want to provide 8TB (8 disks x 1TB each) of data per host just for Microsoft Windows 10 VDI. In each host I will have storage (ceph osd) and compute (on kvm).
I'd like to hear your opinion about theese two configurations: 1.- RAID5 with 8 disks (I will have 7TB but for me it is enough) + 1 OSD daemon 2.- 8 OSD daemons I'm a little bit worried that 8 osd daemons can affect performance because all jobs running and scrubbing. Another question is the procedure of a replacement of a failed disk. In case of a big RAID, replacement is direct. In case of many OSDs, the procedure is a little bit tricky. http://ceph.com/geen-categorie/admin-guide-replacing-a-failed-disk-in-a-ceph-cluster/ What is your advice? Thanks a lot everybody in advance...
