UCSM 2.2.2c Direct Connect C240 M3 internal hard drive question

I have 4 C240 M3 servers being managed by 6248's running UCSM 2.2.2c and they are visible and working.

 

I am going to boot ESX 5.5 from the flexflash SD cards...I read that is supported...

 

I have a raid controller in the server and 1 flash hard drive and 3 sas hard drives...so I need 2 volumes off one raid controller on a C240 M3 direct connected and being managed by UCSM.

My plan is to boot ESX 5.5 off the internal SD cards in the C240s and then configure to 2 volumes for VMware VSAN off the 1 raid controller.

 

Is that supported?

and here the caveat, which answers your question

Maximum of One RAID Volume and One RAID Controller in Integrated Rack-Mount Servers
A rack-mount server that has been integrated with Cisco UCS Manager can have a maximum of one RAID volume irrespective of how many hard drives are present on the server.


All the local hard drives in an integrated rack-mount server must be connected to only one RAID controller. Integration with Cisco UCS Manager does not support the connection of local hard drives to multiple RAID controllers in a single rack-mount server. We therefore recommend that you request a single RAID controller configuration when you order rack-mount servers to be integrated with Cisco UCS Manager.
In addition, do not use third-party tools to create multiple RAID LUNs on rack-mount servers. Cisco UCS Manager does not support that configuration.
