yes, a raid1 system disk is necessary, from my perspective.
And a swap partition is still needed even though the memory is big.

Hi,
Is it a good idea to use a software raid for the system disk (Operating System) on a Ceph storage node? I mean only for the OS not for the OSD disks.
And what about a swap partition? Is that needed?
Best,
Martin
