Is it possible to use a P3608 in an Ubuntu 16.04 server?

Is it possible to use a P3608 in an Ubuntu 16.04 server, and have it run as a single drive (in this case 1.6 TB) while taking advantage of its full IO capabilities?

We are starting with a fresh hardware & software build, and while the other drives seem to be recognized fine, the P3608 gets split into two (2) 800MB nvme devices - which I know is possible, but does not take advantage of the P3608's real capabilities in this configuration.

When I run "lsblk -di", I get the following (drive type column added for clarity):

Drive TypeOS NAMEMAJ:MINRMSIZEROTYPEIntel S3610 1.6TBsdb8:1601.5T0diskIntel P3608 1.6TB (showing as single 800 MB Drive)vme1n1259:10745.2G0diskSupermicro SATADOM 32 GB Drivesdc8:32029.5G0diskHGST HE8 8TB Drivesda8:007.3G0diskIntel P3608 1.6TB (showing as single 800 MB Drive)nvme0n1259:00745.2G0disk

If we were running Windows, I know there are several tools that would address this, but what about in Ubuntu? Is there support for other Linux distributions other than Red Hat/SUSE?

I am running 4.8.0-22-generic version of the kernel.

Also, server hardware configuration consists of the following:

CPU: Intel E5-1650 V4

Memory: DDR4 256 GB (32x8)

Intel C612 chipset

PCI-E 3.0 x16 & x8 slots

Thanks

Hello Stoic,

The Intel® SSD DC P3608 Series features an unique dual storage controller configuration. Because of this, natively the drive will always be displayed as two separate NVMe* storage devices.For full performance we recommend setting up these two halves into a RAID 0 array. Officially we support this setup through the Intel® Rapid Storage Technology Enterprise software, which is unfortunately not Linux* friendy. Since you're using Ubuntu* Server, I can personally recommend the "mdadm" utility, although this is not supported though us.Relevant links:- https://raid.wiki.kernel.org/index.php/RAID_setup# RAID-0 Setting up RAID 0 using 'mdadm' - Linux* RAID Wiki-http://www.intel.com/content/dam/support/us/en/documents/ssdc/data-center-ssds/Intel%20NVMe%20Install%20Guide_330547-003.pdf Intel SSD DC P3608 Series - Installation Guide (Page 13, section 3.3)- http://www.intel.com/content/dam/support/us/en/documents/ssdc/data-center-ssds/Intel_Linux_NVMe_Guide_330602-002.pdf Intel® Linux* NVMe* Driver - Reference Guide for DevelopersNOTE: Any links provided for third party tools or sites are offered for your convenience and should not be viewed as an endorsement by Intel® of the content, products, or services offered there.
