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.
What is your advice?
Thanks a lot everybody in advance...
