Getting Started

The Sunlight support team is on stand by to assist with any installation and configuration issues you may encounter. Link : support portal

Note

In case your system is shipped with a preinstalled Sunlight Enterprise Software platform, you can skip this step and navigate straight to System Configuration.

Note

Please submit a request via our online request support portal to register for the Tech Preview program. A Sunlight, representative will provide all the necessary 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

In order to initialize the Sunlight Enterprise Software platform installation please ensure that a minimum of 2 x 32GB USB thumb drives are available, such as the 32GB SanDisk Ultra Fit USB 3.0 flash drive.

Once the USB image is downloaded, please transfer the data to the raw USB flash drive (the image contains its own partition structure so the downloaded image should be transferred directly to the root directory, not an existing partition). The method for writing the image on the USB flash drive may vary, depending on the type of the Operating system you are using.

For addititonal information on installing the provided images, please visit the following links: - For MAC systems - For Windows systems

At this stage it must be decided which physical blade you wish to designate as the master node to host the cluster controller. In practice any blade can be used as a master node. Please proceed to powering on the 4 nodes for which the USB boot images have been downloaded for.

All of the 10GBit LOM NICs on the blades have to be cabled together into a single logical Layer 2 ethernet network segment. For redundancy reasons and in order to ensure that the High Availability algorithms work correctly, we strongly recommend using separate switches as indicated in the diagram below:

Please read the tutorials of BIOS settings for different hardware platforms, in order to make sure that the installation procedure meets the minimum requirements for running the Sunlight Enterprise Software.

Sunlight Enterprise Software Installation Steps

  • Insert the USB drive and boot up the system
  • Enter the NV-Configure utility
  • Enter Option 1: - Initialise NVMe drives
  • Enter Option 2: - Initialise Installation drives
  • Enter Option 3: - Install to local disk
  • Remove the USB drive when prompted. The system will reboot automatically.
  • Enter the MV-Configure utility again
  • Enter Option 4: - Configure controller network interface (only applies to master node)
  • Enter Option 5: - Configure VLAN ID
  • Enter Option 6: - Configure NexVisor channel and encryption key
  • Enter Option 7: - Configure chassis and blade ids
  • Select Option 8: - Exit and Restart

On first boot, you must ensure that the system BIOS is enabled in order to boot from the USB storage. The following menu options are provided:

Grub boot screen

Select the NV-Configure option and press enter.

Grub boot nv_configure option

The system will boot to a menu system, which provides the following configuration options:

System Configurator screen option 1

Note

When using the configuration utility, a keyboard must be attached (for a remote access, the IPMI interface should be used). Use the TAB key to navigate through the menu or input fields.

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 each drive on the list and go through the initialisation wizard.

Choose the 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), formatting of the drive is required. This ensures there is no data or specific format applied to the drive.

System Configurator screen option 2

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 provides the option of selecting the source drive (USB drive) and then install the platform to the destination drive (local drive) as it has been explained in the previous step. Once complete, the system will prompt you to remove the USB drive and reboot the system. Please re-select the NV-Configure option at the boot up screen to return to this menu.

System Configurator screen option 3

Choose source drive:

Install to local

Choose destination drive:

Install to local

Proccess ended:

Install to local

Accept and reboot:

Remove flash disk - Accept and reboot

Option 4 - (Configure controller network interface)

Configure controller network interface. This option allows the configuration of the IP address on the virtualised controller service that runs when the system boots up. Two options are available, DHCP and static. For the static option, the IP address, net mask, default gateway and DNS settings the controller can be specified.

System Configurator screen option 4

Select OS drive:

Network configuration

Select DHCP or static IP settings:

  • Provide dynamically DHCP settings

DHCP Dynamic Network configuration

  • Provide static settings

Static Network configuration

  • Specify the IP address of the host, the default Gateway, the Netmask and the DNS server.

Network configuration settings

Option 5 - (Configure VLAN ID)

Configure Virtual LANs. This option allows the configuration of the VLAN on the virtualised controller service that runs when the system boots up. Two options are available, default and custom. Default option (defvlan = -1) disables the VLAN feature while the custom option enables this feature with the selected value.

configure VLAN

  • Select the Nexvisor drive to specify the VLAN ID

configure VLAN

  • Select a custom value which will represent the VLAN ID in order to activate the feature. Specify the default VLAN ID to -1 in order to deactivate the VLAN feature.

configure VLAN

Warning

This option should be applied on both Nexvisors (master/slave), regardless whether the VLAN feature is enabled or disabled during the installation process.

Option 6 - (Configure NexVisor channel and encryption key)

Configure the MV channel and the encryption key. This option allows the configuration of the MV channel, which isolates clusters on the same subnet according to the channel. The configuration of the encryption key is also provided, for allowing traffic to flow between the NVs with the same encryption key.

System Configurator screen option 6

  • Choose a drive with a bootable partition:

Channel and Encryption key

  • Enter custom values and press TAB to submit:

Channel and Encryption key

Warning

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

Option 7 - (Configure chassis and blade ids)

Configure chassis and blade id. This option allows the definition of the chassis id as well as the blade id for the specific node being installed. The chassis ID should be a hexadecimal number,(e.g 0x2f1a), while the blade ID should be a decimal number (e.g. 1).

System Configurator screen option 6

Select a drive with a bootable partition:

Chassis and Blade

Change the default values and press TAB to submit new ones:

Chassis and Blade

Warning

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 8 - (Exit and Restart)

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

Exit and Restart

  • Confirm reboot option

Reboot confirmation

Following the configuration options described above, the controller UI will boot up with the declarted IP settings, or a default pre-configured IP address:

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. The duration for the cluster controller to boot up is approximately one minute, however a web browser can be pointed at the IP address of the controller UI which has been configured previously. The following screen can be viewed:

Login Screen

Note

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