Release Notes

Compatibility Guide 2.2.77

This page lists the hardware and software components supported on platforms running DDN Infinia 2.2.77.

Combinations of systems not described here may not be tested or supported by DDN. Contact your DDN Sales Representative with questions or requests for additional compatibility testing.

Hardware Platforms

DDN Infinia 2.2.77 supports the following DDN-supplied hardware platforms:

  • AI2000

Operating System

As of the date of document creation, supported servers must meet the following software requirements:

ProductSupported Version
Ubuntu24.04

Ubuntu 24.04 is the supported base OS. If you have an OS other than Ubuntu 24.04, please contact engineering to discuss a support plan or upgrade path.

Password-protecting the GRUB Boot Loader

By default, DDN does not set a password on GRUB boot loader for DDN Infinia base OS. A password-protected boot loader prevents a node from reboot in case of a crash, potentially evicting the node from the cluster.

DDN Infinia may face potential data loss if too many nodes and drives go down at the same time.

Therefore, DDN does not recommend setting a password on GRUB boot loader. In case you still need to set a password, contact DDN support.

Supported Network Interface Cards

All networking adapters are shipped without transceiver modules.
