Getting Started

Note

The tech team is on-hand to assist with any install and configuration issues you may encounter

Now you have hardware racked up and ready to start. If your system came preinstalled with the Sunlight Enterprise Software platform, then you can skip this step and move straight to System Configuration. Otherwise, you must ensure that you have a minimum of 2 x 32GB USB thumb drives available (such as the 32GB SanDisk Ultra Fit USB 3.0 flash drive. Please submit a request via our online request form to register for the Tech Preview program, and a representative will send you instructions on how to download and retrieve the 2 USB installer images:

  1. Master node - This should be inserted into the blade that will host the cluster controller
  2. Slave node - This is a slave host installer image

Once you have downloaded the USB image you must write the data to the raw USB thumb drive (the image contains its own partition structure so please write this entirely to the root device, not an existing partition). The method for writing the image will vary depending on the type of system you are using. On a MAC system you may find this link helpful. On a Windows desktop system you may find this link helpful.

You can decide at this stage which physical blade you wish to designate as the master node to host the cluster controller, although in practice it can be any of the blades. You are now ready to power on the 4 nodes for which you have downloaded and written the USB boot images earlier.

Firstly you must cable all of the 10GBit LOM NICs on the blades together into a single logical Layer 2 ethernet network segment. For redundancy and to ensure the High Availability algorithms work correctly, we strongly recommend using separate switches:

Before you start the installation please check the tutorials of BIOS settings for different hardware platforms to make sure it meets the requirements to run the Sunlight Enterprise Software.

Sunlight Enterprise Software Installation Steps

  • Insert the USB drive and boot up the system
  • Enter the MV-Configure utility
  • Enter Option 1 - Initialise NVMe drives
  • Enter Option 2 - Initialise Installation drives
  • Enter Option 3 - Install to local disk
  • Remove USB drive when option 3 promotes to do so before the system reboots automatically.
  • Enter the MV-Configure utility again
  • Enter Option 4 - Configure controller network interface (only applied for master node)
  • Enter Option 5 - Configure NexVisor channel and encryption key
  • Enter Option 6 - Configure chassis and blade ids
  • Select Option 7 - Exit and Restart

On first boot, you must ensure that the system BIOS is enabled to boot from USB storage, and you will see the following menu options:

Grub boot screen

Select the MV-Configure option and hit enter. You will boot up to a menu system to enable you to do various configuration tasks:

System Configurator screen

Note

When using the configuration utility, you must have a keyboard attached (or access remotely via the IPMI interface). Use the <TAB> key to select different buttons or input fields on the same screen.

Option 1 - (Initialise NVMe drives)

Initialise NVMe drives. All NVMe drives must be initialised in order to use them for local/distributed storage when the system is booted up and running. Please select every drive in the list and go through the initialisation wizard.

Choose Drive to initialise:

Initialise NVMe drives

Accept and continue:

Initialise NVMe drives

Option 2 - (Initialise Installation drives)

Initialise Installation drives. When installing the system to a local SCSI device (e.g. SATA Dom, SATA SSD or SAS) you should wipe it first using Menu option 2. This ensures there is no existing data or formatting applied to the drive.

Choose Drive to initialise:

Initialize Installation drives

Accept and continue:

Initialise Installation drives

Option 3 - (Install to local disk)

Install to local disk. This wizard will allow you to select the source drive (USB drive) and then install to the destination drive (local drive) that you prepared in the previous step. Once complete, this step will ask you to remove the USB drive and reboot. You should re-select the MV-Configure option at the boot up screen to return to this menu.

Choose source drive:

Install to local

Choose destination drive:

Install to local

Proccess ended:

Install to local

Accept and reboot:

Install to local

Option 4 - (Configure controller network interface)

Configure controller network interface. This option allows you to configure the IP address of the virtualised controller service that runs when the system boots up. You can select from DHCP or static. For the static option you can specify the IP address, net mask, default gateway and DNS settings for the controller.

Choose OS drive:

Network configuration

Select DHCP or Custom IP settings:

Network configuration

Option 5 - (Configure NexVisor channel and encryption key)

Configure the MV channel and the encryption key. This option allows you to configure the MV channel, which isolates clusters on the same subnet according to the channel. Additionally you can configure the encryption key, thus allowing traffic to flow between the MVs with the same encryption key.

Choose a drive with a bootable partition:

Channel and Encryption key

See old values:

Channel and Encryption key

Press tab to submit the new ones:

Channel and Encryption key

Note

The Channel value must a number between 0 and 65534. The Encryption key must be a string of exactly 16 characters, e.g. 0123456789abcdef

Option 6 - (Configure chassis and blade ids)

Configure chassis and blade id. This option allows you to set the chassis id as well as the blade id for the specific node being installed. The chassis ID should be hexadecimal, such as 0x2f1a, and the blade ID should be decimal, such as 1.

Choose a drive with a bootable partition:

Chassis and Blade

See old values and press tab to submit new ones:

Chassis and Blade

Note

The Chassis id must be a Hex value in the format "0x##", e.g. 0xCC82. The Blade id must be a number between 1 and 99.

Option 7 - (Exit and Restart)

Exit and restart. This option will reboot the system back to the initial boot menu.

Exit

After configuration, the controller UI will boot up with the IP settings you configured, or a default pre-configured IP address of:

IP Address 192.168.1.254 (link)
Netmask 255.255.255.0
Default Gateway 192.168.1.1
Default Username administrator
Default Password NexVisor

Now the system is booted up and fully operational. Please configure a local method to access the ethernet segment with the network settings outlined above. It will take approximately one minute to allow the cluster controller to boot up, however you can now point a web browser at the IP address of the controller UI configured previously. You should see the following screen:

Login Screen

Note

For this tech preview release you can boot and run entirely off the USB key inserted in the server blade, although we recommend that you should install the system to a locally attached SATA or SAS drive using the menu option listed above.
