Hello everyone,
We have a Raid 10 server with 4x 2Tb HDDs (spinning disks). The installation runs well with MDRaid 10 and LVM-Thin/Ext4. Overall, it's a static file server that's part of our CDN infrastructure.
The question now is whether ZFS can take the place of MDRaid without compromising performance too much.
Above all, it's a question of harmonizing with our other servers, and not a real need for additional functionality.
Planned installation with ZFS Raid 10: two 2-disks mirror vdevs, which ZFS will then stripe across.
The raid will include the OS, the CTs and a partition with the static files shared in the CTs.
I need feedback on the performance of such an installation. The hardware cannot be changed or upgraded in this case.
EDIT: I won't ask the question for 2 HDDs in Raid 1 with ZFS, as performance is poor in the absence of a L2ARC.
EDIT 2: The server has "only" 32GB of RAM.
Best regards.
