In addition to a custom cable, the user is responsible for verifying that the add-on card is compatible with
the NVIDIA Jetson TX2i, including native driver support. If the driver is not a standard driver used in the
NVIDIA JetPack operating system (OS), the user is responsible for the integration into the OS. For
system integration from the factory, Curtiss-Wright offers application engineering services for modified
COTS (MCOTS) variants. Contact your sales representative for options.

Storage Options
The DuraCOR 312 utilizes multiple storage options. Having a multiple options allows the system to be
more versatile to be able to be a solution for a broad range of environments. This section describes the
various storage options for the DuraCOR 312.
Non-Volatile Memory Express (NVMe)
M.2 Socket
The DuraCOR 312 contains an M.2 B-key for use with an M.2 B+M key with a single (x1) or dual (x2)
PCIe lane card. As mentioned above, the PCIe lanes are Gen 2 (approximately 500 MBps per lane).
The NVMe drives are intended to hold user data, the operating system, or both.
The system is capable of utilizing a wide range of M.2 sizes and capacities. The M.2 device can be B key
or B+M key. The length of the drive may be 2260 or 2280. The capacity is limited to current industry
capabilities for storage densities. Any devices installed in the M.2 socket must be installed at the factory.
Contact your sales representative for drive options.
The use of removable SATA (see below) does not override the PCIe lanes. Thus, the user can use an
M.2 device and a removable SATA device at the same time.
SATA
The DuraCOR 312 has a single SATA Gen 2 lane. This SATA lane has been routed to two locations: M.2
socket and 7-pin SATA header for removable storage. The SATA device may be used to store data,
operating system, or both.
