The creation of two DataVIPs is required when setting up a SuperPD based solution. After an initial subnet is determined, creation of two DataVIPs will ensure that the aggregate mount options on the DGX will properly be able to connect and communicate with the FlashBlade array.

Log into the FlashBlade as the pureuser account to modify the array configuration.
Note:

The generic login and password is pureuser/pureuser. This should be changed after installation is complete.

Appropriate physical installation of the FlashBlade and proper array configuration must be completed before you will be able to log into the array. Please ensure proper physical installation and configuration have been completed prior to continuing with this document.

The management IP of the FlashBlade is assigned during the configuration of the array as part of the physical installation process. Please see the note above regarding proper physical installation and configuration before continuing.

Example:
ssh pureuser@<mgmntIPofFlashBlade>

Create Subnet

Once you are logged into the management CLI, you can create the proper subnets based on the previously entered array configuration information that is part of the physical installation and configuration process.

Example:
puresubnet create --prefix 100.127.199.0/25 --vlan 34 --gateway "" --mtu 9000 --lag uplink testnet

Create Data VIP(s)

After the appropriate subnet has been created based on the array configuration step, you can create the network IPs that will carry the data traffic to and from the FlashBlade. These are called DataVIPs. Two are required to meet the proper DGX mount configuration for NVIDIA DGX SuperPOD clusters.

Example:
purenetwork vip create --address 100.127.199.4 --servicelist data data-34-90
purenetwork vip create --address 100.127.199.5 --servicelist data data-34-90

Create Filesystem

After the network subnet and DataVIPs have been created you can create a filesystem. The size of the file system depends on two factors:

  1. How much capacity exists on the FlashBlade array.

  2. How large of a file system is requested by the customer.

Please work with the customer to determine the appropriate size of the file system.

Example: 
purefs create --size 1T purefb

Enable NFSv3 Protocol

After the file system has been created, assign the appropriate file protocol to the file system. For FlashBlade//S based NVIDIA DGX SuperPOD installations, you must set the protocol to NFSv3.

Example:
purefs add purefb --protocol nfsv3
