I dont know what you are talking of since an RP3440 is a small rack server, the hardware depends on what options you ordered: in standard it has a Dual channel Ultra160 SCSI controller and can hold 3 internal disks so it limits RAID choices dont you think?
Usually you would have 2 internal disks each on a separate channel for system purpose in mirror (RAID 1) and SAN Fiber channel HBAs for the rest...

Addendum...
You could use this command to see: Here its my RP5450...

esiop

ESIOP(4)						   BSD Kernel Interfaces Manual 						  ESIOP(4)

NAME

     esiop -- Enhanced Symbios Logic/NCR 53c8xx SCSI driver

SYNOPSIS

     esiop* at pci? dev ? function ?
     options SIOP_SYMLED
     scsibus* at esiop?

DESCRIPTION

     The esiop driver provides improved support over siop(4) for the Symbios Logic/NCR 53x8xx series of SCSI controller chips:

	   -   53c825 and 53c825a (Fast-Wide SCSI)
	   -   53c875 and 53c875j (Ultra-Wide SCSI)
	   -   53c876 (Dual Ultra-Wide SCSI)
	   -   53c885 (Ultra-Wide SCSI and Ethernet)
	   -   53c895 (Ultra2-Wide SCSI)
	   -   53c896 (PCI 64bit, dual Ultra2-Wide SCSI)
	   -   53c1010-33 (PCI 64bit, dual Ultra160 SCSI)
	   -   53c1510d (PCI 64bit, dual Ultra2-wide SCSI)
     Older adapters are supported by the siop(4) driver.

     The SIOP_SYMLED option causes the driver to report SCSI activity on the GPIO pin 1, which is connected to the activity LED on some adapters.
     At this time only the 53c895 based Symbios and Tekram adapters are known to require this.

HISTORY

     The esiop driver first appeared in NetBSD 1.6.

AUTHORS

     The esiop driver was written by Manuel Bouyer <Manuel.Bouyer@lip6.fr> for NetBSD.
