Please share your ideas for disks best performance using SAS2208 based RAID 0 (4x DC SSD).
Guest VM has thick eager zeroed disks.
What suppose to be a strip size on RAID? Should I do it same as VMFS 1MB ?
Guest OS FS would be ext4/btrfs. Same question, what best block size for FS ? Disks will be used for heavy MYSQL load (of course with COW disabled in btrfs).
In my humble opinion using Raid0 for a VMFS-datastore on a standalone host is a suicide mission. Dont do it.
A single power-failure may kill your data in one stroke.
Raid 0 having performance but there is no redundancy and any failure data will lose .
You may go with RAID 10 if your raid controller support raid 10 .
You may share the controller model , disk you are going to use (type , RPM and model ) and what is the purpose of the this raid ( OS / media / backup )
based on this we can decide which stripe size can be used else you won't get the benefit of raid you choose .
