Moin, We use in our Enviroment three ssd drives with four TB space in a Raid 5 on a adaptec contrioller and use on the ovirt installation the jbod on the drive which the Adaptec Controller provide. If we have three Servers in place we use the same config but each volume will be replicate to the other servers. Next year we plan to use a Raid 10 with four drives and the rest will be the same. I think the speed will not be the best one but für the data we have enough redundancy im place. brMarcel Am Donnerstag, dem 02.12.2021 um 18:30 +0000 schrieb Strahil Nikolov via Users:
For SSDs , I would use each ssd as a single brick. Don't forget to align the LVM/XFS in case you are not using Gluster's Ansible /which oVirt also uses for deployment/ : https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/ht...

There is 15 Spin disks total
9 SSD disks total
Spin will be split into 3x RAID-5's on the physical hosts (5 disks) SSD will be split into 3x RAID-5's on the physical hosts (3 disks)
My plan was as you said, create a single brick on each of the 3 spin RAID-5's and a single brick on each of the 3 SSD RAID-5's - just wasn't sure if there was a better way to go about it.
Thanks, Joe

if you go with RAID 5 option it is expected to have performance degradation but you will have double protection for your data.
my suggestion, go with each HDD disks as individual bricks with replica 3 volumes and same for SSD's _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/6777XHHUNWWFXW...
