.. important::
    - Optimal data transfer mechanisms such as HTTP, multithreading, and similar optimizations are not possible with Omniverse Nucleus Workstation​.
    - Advanced authentication features, like Single Sign On, when shipped, will not be available with Omniverse Nucleus Workstation. Only the most basic login/password based auth with internal to this instance accounts will ever be supported.

Omniverse Nucleus Workstation Hardware Minimum Requirements
------------------------------------------------------------------------------------------------------------
- CPU: 6+ Cores​ (3.0 GHz or Higher)
- Memory: 16 GB ​
- Storage: 50 GB

Omniverse Enterprise Nucleus Docker Hardware Minimum Requirements
------------------------------------------------------------------------------------------------------------
- CPU: 12 Cores​ (3.0 GHz or Higher)
- Memory: 32 GB ​
- Storage: 250 GB

.. note::
    General rules for designing file server.

    - Larger system memory will improve OS filesystem cache, this important for large amount of concurrent file transfer​.
    - Storage will depend on project size. For M&E VFX this may be 100s of TBs.​
    - Additional cores for LFT as number of concurrent users grows. For large servers recommend running LFT on separate CPU socket.
