1. Introduction to the NVIDIA DGX-1 Deep Learning System

The NVIDIA® DGX-1™ Deep Learning System is the world’s first purpose-built system for deep learning with fully integrated hardware and software that can be deployed quickly and easily.



Using the DGX-1: Overview

The NVIDIA DGX-1 is designed to operate in one of two modes - Base OS mode, and Cloud Managed mode. However, Cloud Management is currently not available, but will be available at a future date. Availability will vary by region.

Base OS mode provides the base operating system on the DGX-1 for customers who want to use their own on-site scheduling and management software and who will build and run their own applications.

  2. Enter all required information and then click SUBMIT to complete the registration process and receive all warranty entitlements and, if applicable, DGX-1 support services entitlements.

    If you do not have the information, email NVIDIA Enterprise Support at enterprisesupport@nvidia.com.

Obtaining Software and Software Updates

You must register your DGX-1 in order to receive software updates. Once registered, you will receive an email notification whenever a new software update is available. You can access OTA instructions as well as software downloads through the Enterprise Support site as follows:

  • From your browser, go to NVIDIA Enterprise Services, and log in.
  • Click the Announcements tab, which contains download links and supplemental documentation.
  • Refer to the DGX-1 Software Release Notes for instructions on how to perform an OTA software update.

Choosing a Setup Location / Site Preparation

Decide on a suitable location for setting up and operating the DGX-1. The location should be clean, dust-free, and well ventilated.

General Conditions

  • Prepare a sufficiently wide aisle to accommodate the unboxed chassis (chassis dimensions - 5.16”H x 17.5"W x 34.1"D).
  • The rack must accommodate a 134 lb, 3U rack mount system (chassis dimensions - 5.16”H x 17.5"W x 34.1"D).
  • The rack must have square mounting holes.
  • After installing the unit, leave enough clearance in front of the rack to enable you to open the front door of the rack completely (25").
  • Leave approximately 30" (76.2cm) of clearance in the back of the rack to allow for sufficient airflow and ease in servicing.
  • Always make sure the rack is secured and stable before adding or removing the appliance or any other component.
  • Prepare adequate sound-proofing: The equipment fans can generate 72-100 dBA.

Environmental Conditions

  • Operating environment
    • Temperature: 5 ◦ C to 30 ◦ C (41 ◦ F to 86 ◦ F)
    • Relative humidity: 20% to 85% noncondensing
  • Air flow
    • The chassis fans can produce a maximum of 340 CFM of air flow.
    • Do not block the ventilation areas at the front and rear of the chassis.
    • Minimize any restrictions on air flow around the chassis.

Connections

  • Power:
    • The DGX-1 is powered through four 1600W power supply units, each rated at 200-240VAC, 8A, 50/60 Hz. Total system power: 3200W
    • C13/C14 cables provided for each power supply to connect to a compatible PDU.
  • Network: Dual 10GBASE-T RJ45 connection
  • IPMI: 10/100BASE-T (GbE) RJ45 connection
  • InfiniBand: Qty 4 - QSFP28 ports, InfiniBand and Ethernet compliant

Preparing for Network Access

  • The IPMI port and Ethernet ports can be connected to your local LAN.

    These ports are configured for DHCP by default.

    • To use DHCP, connect the port to a local DHCP server which should provide an IP address and assign a DNS configuration to the DGX-1.
    • If DHCP is not available, then you will need to set up a static IP for each Ethernet port.
  • NVIDIA recommends that customers follow best security practices for BMC management (IPMI port). These include, but are not limited to, such measures as:
    • Restricting the DGX-1 IPMI port to an isolated, dedicated, management network
    • Using a separate, firewalled subnet
    • Configuring a separate VLAN for BMC traffic if a dedicated network is not available
  • If you will be operating the DGX-1 in cloud-managed mode, then
    • Make sure that DNS is enabled
    • Make sure that the ports listed in the following table are open and available on your firewall to the DGX-1:
    Port (Protocol) Direction Use
    53 (UDP) Outbound DNS
    80 (TCP) Outbound HTTP, package updates
    123 (UDP)

    Outbound/

    Inbound

    NTP client
    443 (TCP)

    Inbound/

    Outbound

    For internet (HTTP/HTTPS) connection to DGX Cloud Services

    If port 443 is proxied through a corporate firewall, then WebSocket protocol traffic must be supported

    2376 (TCP) Inbound For interacting with running containers using attach/exec commands
  • If you will be using the DGX-1 in Base OS mode, make sure your network can connect to the following:
    • http://us.archive.ubuntu.com/ubuntu/
    • http://security.ubuntu.com/ubuntu
    • http://international.download.nvidia.com/dgx1/repos/
    • https://apt.dockerproject.org/repo

    If access to those URLs requires use of a proxy, refer to Setting Up a System Proxy for setup instructions.

Unpacking the DGX-1

  1. Remove the shrinkwrap.
  2. Collapse the yellow "Do not stack" cone".
  3. Open the main DGX-1 box, then remove the accessory and rail kit boxes.

    CAUTION: At least four people, or a mechanical assist, are required to remove the DGX-1 from the box. To reduce the risk of personal injury or damage to the equipment, always observe local occupational health and safety requirements and guidelines for material handling.

    DO NOT use the handles at the front of the DGX-1 to lift the unit. The handles are designed for sliding the unit out of a rack, and not for carrying the full weight of the DGX-1.

  4. Preserve and retain packaging.

What's In the Box

Be sure to inspect each piece of equipment shipped in the packing box. If anything is missing or damaged, contact your supplier.

What’s included with your NVIDIA DGX-1:

  • NVIDIA DGX-1
  • Bezel
  • Rail hardware kit
  • Accessory Box
    • AC Power Cables (qty 4 – US C13/14, compatible with data center PDUs)
    • Hard disk bay screws
    • Toxic Substance Notice & Safety Instructions
    • Quick Start Guide
    • DVD containing source files for open source software
Note: The four power cables included in the box are not optional. All power cables are necessary and must be plugged into separate circuits; maximum power draw 8A each.

Installing the DGX-1 Into a Rack

CAUTION: To prevent bodily injury when mounting or servicing the DGX-1 in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety.

• The DGX-1 should be mounted at the bottom of the rack if it is the only unit in the rack.

• When mounting the DGX-1 in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the DGX-1 in the rack.

• The DGX-1 weighs approximately 134 lbs, so an equipment lift is required to safely lift the unit and then accurately align the chassis rails with the rack rails.

DO NOT use the handles at the front of the DGX-1 to lift the unit. The handles are designed for sliding the unit out of a rack, and not for carrying the full weight of the DGX-1.

Installing the Rails

Note: The rail assemblies shipped with the appliance fit into a standard 19” rack between 26-inches and 33.5-inches deep (66 cm to 85 cm). The outer rail is adjustable from approximately 23.5” to 34” (59.7 cm to 86.4 cm)

Refer to the instructions in the rail packaging for details on installing the rails onto the rack and chassis.

The following are supplemental instructions:

  1. Use a Phillips screwdriver to assist in mounting the rails to the rack.
  2. If necessary, detach the inner rails from the outer slide rails.
  3. Follow any designations on the inner rail (or its outer rail mate) to determine the proper orientation and positioning to connect to the chassis, then secure to the chassis.IMPORTANT: Make sure that the reinforced hole at the front end of the rail is positioned on the bottom side of the rail, and that it aligns with the thumbscrew on the front of the DGX-1. If the hole is positioned on the top side, then the rail is on the wrong side of the DGX-1 and the DGX-1 will not fit properly in the rack.
  4. Follow any designations on the outer slide rail to determine front/back and left-side/right-side positioning against the rack.
  5. Secure the back of one of the slide rails to the rack, then extend the rail until it fits securely to the front of the rack.
  6. Secure the slide rail to the front of the rack.
  7. Repeat steps 4-6 for the other slide rail.

Mounting the DGX-1

CAUTION: Stability hazard — The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the DGX-1 out for servicing. Failure to stabilize the rack can cause the rack to tip over.
  1. Confirm that theDGX-1 has the inner rails attached and that you have already mounted the outer rails into the rack.
  2. With the front of the unit facing away from the rack, use an equipment lift to assist in sliding the unit into the rack as follows:

    CAUTION: The DGX-1 weighs approximately 134 lbs, so an equipment lift is required to safely lift the unit and then accurately align the chassis rails with the rack rails.

    1. Align the inner chassis rails with the front of the outer rack rails.
    2. Slide the inner rails into the outer rails, keeping the pressure even on both sides (you may have to depress the locking tabs when inserting).

      When the DGX-1 has been pushed completely into the rack, you should hear the locking tabs "click" into the locked position.



  3. Lock the unit in place using the thumb screws located on the front of the unit.





Attaching the Bezel

The bezel is designed to attach easily to the front of the DGX-1.

  1. Prepare the DGX-1 by making sure that the power supply handles (located at the power supply fans) are flipped up.



  2. Move any other obstructions, such as cable ties, away from the outer edge of the DGX-1.
  3. With the bezel positioned so that the NVIDIA logo is visible from the front and is on the left hand side, line up the pins near the corners of the DGX-1 with the holes in back of the bezel, then gently press the bezel against the DGX-1.



    The bezel is held in place magnetically .

Connecting the Power Cables

  1. Open the accessroy box and remove the four C13/C14 power cables.
  2. Use the cables to connect each of the four plugs at the right-rear of the DGX-1 to a PDU.



  3. Secure each cable to the DGX-1, using the power cable retention clips attached to the power plugs.
  4. Connect each cable to the PDU. At a minimum, ensure that each cable is connected to a different phase or breaker on the PDU. Ideally, each cable should connect to a different PDU.
  5. Verify that each cable is firmly inserted into the PDU. There is usually a click to indicate full insertion.

Connecting the Network Cables

  1. Using an Ethernet cable, connect one of the dual Ethernet ports (em1 or em2) to your LAN for internet access to the NVIDIA Cloud Portal, remote access to launched application containers on the DGX-1, or to connect to the DGX-1 using SSH.



    The left-side port is em2, and the right-side port is em1.
    Note: NVIDIA recommends connecting only one of the Ethernet ports to your LAN. If you are connecting both Ethernet ports, they must each be connected to separate networks, The DGX-1 is not configured from the factory to have multiple Ethernet interfaces on the same network.
  2. Using an Ethernet cable, connect the IPMI (BMC) port to your LAN for remote access to the base management controllerr (BMC). Vefiy that all network cables are firmly inserted into the DGX-1 and the assocated network switch.

Setting Up the DGX-1

These instructions describe the setup process that occurs the first time the DGX-1 is powered on after delivery. Be prepared to accept all EULAs and to set up your username and password.

  1. Connect a display to the VGA connector, and a keyboard to any of the USB ports.



  2. Power on the DGX-1.



    When you power on the DGX-1 for the first time, you are presented with end user license agreement (EULAs) for the NVIDIA software.

  3. Accept all EULAs.

    After EULAs are accepted, you are prompted to configure the Ubuntu OS.

  4. Perform the steps to configure the Ubuntu OS.
    • Select your time zone and keyboard layout.
    • Create a user account with your name, username, and password.

      You will need these credentials to log in to the DGX-1 as well as to log in to the BMC remotely. When logging in to the BMC, enter your username for both the User ID as well as the password. Be sure to create a unique BMC password at the first opportunity..

    • Choose a primary network interface for the DGX-1.
      Note: After you select the primary network interface, the system attempts to configure the interface for DHCP and then asks you to enter a hostname for the system. If DHCP is not available, you will have the option to configure the network manually. If you need to configure a static IP address on a network interface connected to a DHCP network, then select Cancel at the Network configuration – Please enter the hostname for the system screen. The system will then present a screen with the option to configure the network manually.
    • Choose a hostname for the DGX-1.
    • Choose to install predefined software.

      Toggle the space bar to select or deselect the software to install, then select OK to continue.

      By default, the DGX-1 installs only minimal software packages necessary to ensure system functionality. During installation, you can deselect the OpenSSH package; however, NVIDIA recommends that you keep this package selected, and uninstall it only if required by your IT security policy.

    The system completes the installation. You are then presented with the system login prompt:
    <hostname> login:
    Password:
  5. Log in.
  6. If your network is configured for DHCP, then make sure that dynamic DNS updates are enabled. Check whether /etc/resolv.conf is a link to /run/resolvconf/resolv.conf.
    $ ls -l /etc/resolv.conf
    Expected output:
    lrwxrwxrwx 1 root root 29 Dec  1 21:19 /etc/resolv.conf ->
    ../run/resolvconf/resolv.conf
    • If the expected output appears, then skip to step 7.
    • If this does not appear, then enable dynamic DNS updates as follows:
    1. Launch the Resolvconf Reconfigure package.
      $ sudo dpkg-reconfigure resolvconf
      The Configuring resolvconf screen appears.
    2. Select <Yes>when asked whether to prepare /etc/resolv.conf for dynamic updates.
    3. Select <No> when asked whether to append original file to dynamic file.
    4. Select <OK> at the Reboot recommended screen. You do not need to reboot. You are returned to the command line.
    5. Bring down the interface, where <network interface> is em1 or em2, whichever you have set up as your primary network interface.
      $ sudo ifdown <network interface>
      Expected output:
      ifdown: interface <network interface> not configured
    6. Bring up the interface, where <network interface> is em1 or em2, whichever you have set up as your primary network interface.
      $ sudo ifup <network interface>
      Expected output (last line):
      …
      bound to <IP address> -- renewal in …
    7. Repeat step 6 to confirm that /etc/resolv.conf is a link to /run/resolvconf/resolv.conf.
  7. Make sure that the nvidia-peer-memory module is installed.
    $ lsmod | grep nv_peer_mem
    If the following output appears, then your DGX-1 setup is complete and you do not need to perform the next steps.
    nv_peer_mem            16384  0
    nvidia              11911168  30

       update-initramfs: Generating /boot/initrd.img-4.4.0-45-generic
      
    2. Add the module to the Linux kernel.
       $ sudo modprobe nv_peer_mem
      
      There is no expected output for this command.
    Your DGX-1 setup is completed.

Configuring a System Proxy

If your network requires use of a proxy, then edit the file /etc/apt/apt.conf.d/proxy.conf and make sure the following lines are present:

Acquire::http::proxy "http://<username>:<password>@<host>:<port>/"; 
Acquire::ftp::proxy "ftp://<username>:<password>@<host>:<port>/"; 
Acquire::https::proxy "https://<username>:<password>@<host>:<port>/";

If you will be using the DGX-1 in base OS mode, then after installing Docker on the system, refer to the information at https://docs.docker.com/engine/admin/systemd/#http-proxy. This is to ensure that Docker is able to access the DGX Container Registry through the proxy.

Configuring NFS Mount and Cache

The DGX-1 includes four SSDs in a RAID 0 configuration. These SSDs are intended for application caching, so you must set up your own NFS drives for long term data storage. The following instructions describe how to mount the NFS onto the DGX-1, and how to cache the NFS using the DGX-1 SSDs for improved performance.

Note: Skip this section if you are going to use the DGX-1 in cloud-managed mode. The DGX Cloud Services software will set up the NFS cache for you as part of the cloud-managed mode configuration. Similarly, in cloud-managed mode, the person setting up the job will specify any NFS mount requirements for the job at that time.
  1. Check if the cache daemon is installed and configured.
    $ service cachefilesd status
    If the output indicates that cachefilesd is disabled, continue with the following steps. Otherwise, skip to step 7.
  2. Install the cache daemon.
    $ sudo apt-get install cachefilesd
  3. Edit the cache daemon startup file.
    $ sudo vi /etc/default/cachefilesd
    Uncomment the "RUN=yes" line in the startup file and then save the file.
  4. Configure the cache daemon for the DGX-1.
    1. Open the cache daemon configuration file.
      $ sudo vi /etc/cachefilesd.conf
    2. Edit the contents to match the following, then save the file.
      dir /raid
      tag dgx1cache
      brun 25%
      bcull 15%
      bstop 5%
      frun 10%
      fcull 7%
      fstop 3%
  5. Start the cache daemon.
    $ service cachefilesd start
  6. Verify the cache daemon started properly.
    $ service cachefilesd status
    Expected output.
    Checking status of FilesCache daemon cachefilesd
  7. Configure an NFS mount for the DGX-1.
    1. Edit the filesystem tables configuration.
      sudo vi /etc/fstab
    2. Add a new line for the NFS mount, using the local mount point of /mnt.
      <nfs_server>:<export_path> /mnt nfs rw,noatime,rsize=32768,wsize=32768,nolock,tcp,intr,fsc,nofail 0 0
      • /mnt is used here as an example mount point.
      • Consult your Network Administrator for the correct values for <nfs_server> and <export_path>.
      • The nfs arguments presented here are a list of recommended values based on typical use cases. However, "fsc" must always be included as that argument specifies use of FS-Cache.
    3. Save the changes.
  8. Verify the NFS server is reachable.
    ping <nfs_server>
    Use the server IP address or the server name provided by your network administrator.
  9. Mount the NFS export.
    sudo mount /mnt
    /mnt is the example mount point used in step 7.
  10. Verify caching is enabled.
    cat /proc/fs/nfsfs/volumes
    Look for the text FSC=yes in the output. Upon rebooting, the NFS should be mounted and cached on the DGX-1.

3. Configuring and Managing the DGX-1

This chapter describes the following DGX-1 configuration and management tasks:

Obtaining MAC Addresses

These instructions explain how to determine the MAC addresses for the IPMI port (BMC) as well as both ethernet ports of the DGX-1.

The ports are, from left to right, IPMI (BMC), em2, em1.

  1. Connect a display to the DGX-1 VGA connector and a keyboard to any USB port on the DGX-1.
  2. Turn the DGX-1 on or reboot.
  3. At the NVIDIA logo boot screen, press [F2] or [Del] to enter the BIOS setup screen.

  4. Select the Advanced tab from the top menu, then scroll down to view the two Quanta Dual Port 10G BASE-T Mezzanine items.

    The first item shows the MAC address for ethernet port em1, and the second item shows the MAC address for em2.
  5. Navigate to and select Server Mgmt from the top menu, then scroll down to and select BMC network configuration.

  6. Scroll down to view the Station MAC address.

    This shows the MAC address for the BMC.

Using the BMC

The DGX-1 includes a baseboard management controller (BMC) that lets you manage and monitor the DGX-1 independently of the CPU or operating system. You can access the BMC remotely through the Ethernet connection to the IPMI port.

This section describes how to access the BMC, and describes a few common tasks that you can accomplish through the BMC. It is not meant to be a comprehensive description of all the BMC capabilities.

To access the BMC remotely:

  1. Make sure you have connected the IPMI port on the DGX-1 to your LAN.
  2. Open a Java-enabled browser within your LAN and go to http://<IPMI IP Address>/. Use Firefox or Internet Explorer. Google Chrome is not officially supported by the BMC.

  3. Log in. Your initial log in credentials are based on the ones you created when you first set up the DGX-1. Enter your username for both the User ID as well as the Password. User ID: <your username> Password: <your username>.
  4. Be sure to change your password immediately to ensure the security of the BMC. See the next section for instructions on how to change your BMC password.

Creating a Unique BMC Password for Remote Access

When you set up the DGX-1 upon powering it on for the first time, you set up a username and password for the system. These credentials are also used to log in to the BMC remotely, except that the BMC password is the username.

It is strongly recommended that you create a unique password as soon as possible.

Create a unique BMC password as follows:

  1. Open a Java-enabled web browser within your LAN and go to http://<IPMI IP address>/.

This includes making sure personnel and equipment are connected to a common ground, such as by wearing a wrist strap connected to the chassis ground, and placing components on static-free work surfaces.

The DIMMs are located on the motherboard tray, which is accessible from the rear of the DGX-1.

  1. Turn off the DGX-1 and disconnect all network and power cabling.
  2. Remove the motherboard tray.
    1. Locate the locking levers for the motherboard tray at the rear of the DGX-1. There are two sets of locking levers. The locking levers for the motherboard are the bottom set.

    2. Rotate the retention clasps inward towards the center of the unit.

      The retention clasps hold the locking levers in place. Rotating the clasps inward releases the locking levers.
    3. Swing the locking levers out and then use then to pull the motherboard tray out of the unit.

      Do not pull the unit by the blue retention clasps; they may break.
    4. Set the motherboard tray on a clean work surface, and position it so that the locking levers are at the top as you look down on the tray.

      The DIMMs are on a printed circuit board on the left side of the tray.
  3. Using the figure below as a guide, locate the DIMM corresponding to the ID of the faulty DIMM as reported in the BMC log.

  4. Remove the DIMM.
    1. Press down on the side latches at both ends of the DIMM socket to push them away from the DIMM. This should unseat the DIMM from the socket.
    2. Pull the DIMM straight up to remove it from the socket.
  5. Carefully insert the replacement DIMM.
    1. Make sure the socket latches are open.
    2. Positon the DIMM over the socket, making sure that the notch on the DIMM lines up with the key in the slot, then press the DIMM down into the socket until the side latches click in place.
    3. Make sure that the latches are up and locked in place.
  6. Carefully insert the motherboard tray back into the unit, then swing the locking levers flat against the tray and secure them in place with the retention clasps.

  3. Verify that the OFED software was installed correctly.
     $ modinfo mlx5_core | grep -i version | head -1 
    Example output:
    Version : 3.4-1.0.0
    DGX-1 OS release 1.0 should have OFED software 3.2. DGX-1 OS release 2.0 should have OFED software 3.4.
  4. Restart the InfiniBand services so that the new card is recognized.
    1. Restart the InfiniBand service.
      $ sudo service openibd restart
    2. Restart the Service Manager service.
      $ sudo service opensmd restart
    3. Verify that the service has started.
      $ service openibd status
        openibd start/running
      $ service opensmd status
        OpenSM is running...
    4. If the services do not start, verify
      • That the drivers are loaded according to step 3.
      • That the associated cables are connected to the InfiniBand ports.
      • The state of ibstat (refer to step 7)
      • Whether errors are reported in /var/log/syslog.
      If these steps do not indicate a problem andyet the services still do not start, contact NVIDIA Enterprise Support and obtain an RMA for the card.
  5. Verify the firmware version.
    $ cat /sys/class/infiniband/mlx5*/fw_ver
