My RAID controller is Cisco 12G SAS Modular Raid controller.
On the CIMC page of the server, I can only choose to create RAID1, RAID0 or RAID10. I have nowhere to create a RAID5 virtual drive.
This is normal Is it? Is this a limitation of my RAID controller?
Thank you
Without any write cache, only RAID levels 0, 1 and 10 are supported.

The supported RAID levels of this controller depend on the amount of write cache based on modular flash memory installed.
