[ovirt-users] Raid configuration for single instance

Hello everyone, Based on your experiance or well know best practices can you provide me with an advice on raid configuration ? I have a single server, that will have a couple of brand new enterprise grade ssds, spinning and one pci nvme card. The server ( Dell PE r630 ) comes wirt Perc h730p raid controller with 2gb cache. I am thinking of creating a raid 1 array with the 2 of ssd's and ne raid10 array woth the rest of for spinning hdds. Then different gluster volume on each, to provide me 2 ( ssd / sata ) storage domains. What do you think on haveing raid1 / raid10 as underlying HA storage for gluster volumes ? At the moment a have some consumer devices ( samsung evo & seagate spinning shingled type ) and about every day the vms get into "VM has been paused due to storage IO errors" - i am thinking because of bad type hdds. Any thoughts on these ? Thank you , Leo -- Best regards, Leo David
