Using RAID Controller for OSD and JNL disks in Ceph Nodes

[Sanjoy Dasgupta <sanjoy.dasgupta@xxxxxxxxx>]

Hi!

This is an often discussed and clarified topic, but Reason why I am asking is because

If We use a RAID controller with Lot of Cache (FBWC) and Configure each Drive as Single Drive RAID0, then  Write to disks will benefit by using FBWC and accelerate I/O performance. Is this correct assumption ?

Also, it indeed helps, what are the downside of using RAID Controller with Cache in above manner (Apart from Cost of RAID controller) ?
