I am currently running a raid 10 with 6 x 250 GB samsung 850 Pro SSDs with an EXT4 files system.
In the next couple of weeks I am going to remake the raid array using 8 x 250 GB Samsung 850 Pro SSDs with an EXT4 file system
On this array I house the user home directories, business files, docker, plex, NFS mounts for VM's
I am trying to figure out if the default values for when OMV creates a raid 10 with SSDs is correct. I would like to maximize the performance of this raid.
System details: drives attached via an LSI SAS HBA 6GB/s - 8 port, so each drive has its own connection. The system itself has 48 gigs of ram and dual Xeon X5670 CPU. The network is 10 GB SFP+
The default setup of mdadm is a 512k chunk ..... is this correct for an SSD setup ?
Now for the EXT4 file system are the default /etc/fstab sufficient for SSD Raid? I see the discard flag, so I am assuming trim is active, but should something else be set as this is an SSD high performance setup ?
Thank you !!
