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...

TRM(4)							   BSD Kernel Interfaces Manual 						    TRM(4)

NAME

     trm -- Tekram TRM-S1040 ASIC based PCI SCSI host adapter driver

SYNOPSIS

     trm* at pci? dev ? function ?
     scsibus* at trm?

DESCRIPTION

     The trm driver supports PCI SCSI host adapters based on the Tekram TRM-S1040 SCSI ASIC.

HARDWARE

     Supported SCSI controllers include:

	   Tekram DC-315 PCI Ultra SCSI adapter without flash BIOS and internal SCSI connector

	   Tekram DC-315U PCI Ultra SCSI adapter without flash BIOS

	   Tekram DC-395U PCI Ultra SCSI adapter with flash BIOS

	   Tekram DC-395UW PCI Ultra-Wide SCSI adapter with flash BIOS

	   Tekram DC-395F PCI Ultra-Wide SCSI adapter with flash BIOS and 68-pin external SCSI connector

     For Tekram DC-390 PCI SCSI host adapter, use pcscp(4) driver.

     For Tekram DC-310/U and DC-390U/UW/F PCI SCSI host adapters, use siop(4) driver.

AUTHORS

     The trm driver was originally written for NetBSD 1.4/i386 by Erich Chen of Tekram Technology, and Rui-Xiang Guo rewrote the driver to use
     bus_space(9) and bus_dma(9) for NetBSD 1.6.
