Compatibility and Support

Introduction

This document explains how Nasuni components integrate with one another and with third-party infrastructure. Use the sections below, based on what you need:

Current supported versions

Update chokepoints

Before updating, you might need to install these mandatory intermediate versions:

For detailed instructions, see Updating Nasuni software.

Updating Nasuni software

Introduction

Updating Nasuni components from your current software version to a target software version might require installing certain intermediate versions first. This is because certain versions have introduced new features that make them incompatible with earlier versions. We call these special intermediate versions “chokepoints“. Therefore, it is important for you to find and follow the appropriate update path for your current version.

Key Principle: Always update the NMC first, then update any Edge Appliances. The NMC must be able to manage all Edge Appliance versions in your environment.

Edge Appliance update paths

Mandatory Chokepoints

The following  versions are required chokepoints. You must update to these versions before proceeding to later versions.

Specific update paths

Determine the software version your Edge Appliance is running.

9.15.x or later

You are on the current update path. Update directly to the next version:

9.12.x or 9.14.x

You must reach version 9.15.x before updating to 10.x:

9.7.x through 9.10.x

You must pass through two chokepoints. First, version 9.9.5 or 9.10.2. Then version 9.12.x:

9.0.x through 9.5.x

You must pass through three chokepoints. First, version 9.5.x. Then version 9.9.5 or 9.10.2. Then version 9.12.x:

8.x or earlier  

You have a longer update path. Contact Nasuni Support for guidance on your specific situation.

• Version 7.10.9+ is required before updating to 8.0.x
  Therefore, if your version is before 7.10.9, update to 7.10.9 first.

• Version 8.8.3+ is required before updating to 9.0.x
  Therefore, if your version is after 7.10.9 but before 8.8.3, update to 8.8.3 first.

• After updating to 9.0.x, continue with the 9.0.x update path as described above.

NMC Update Paths

Mandatory Chokepoints

The following  versions are required chokepoints. You must update to these versions before proceeding to later versions.

Specific NMC update paths

Determine the software version your NMC is running.

25.1.x or later

You are on the current update path. Update directly to the next version:

23.2.x through 24.1.x

You must reach version 24.1.6 before updating to 25.1.x:

22.x through 23.1.x

You must reach version 22.3.5 or 23.1.2, then version 24.1.6, then version 25.1.x:

21.2.x or earlier

You must reach version 22.3.5, then version 24.1.6, then version 25.1.x:

Edge Appliance and NMC Compatibility

The NMC must be compatible with all Edge Appliances it manages. Use this information to verify compatibility.

Compatibility rules

1. The NMC version should be equal to or newer than the Edge Appliance version it manages.

2. There is a maximum version gap. Very old Edge Appliances might not work with the newest NMC.

3. Update the NMC first, then update Edge Appliances (NEAs).

Current compatibility of NEA with NMC (NMC 23.1+)

Note: Edge Appliance versions 9.5.x and earlier are only compatible with NMC versions 22.2.x and earlier. See legacy compatibility below.

Legacy Compatibility (NMC 22.3 and earlier)

For detailed legacy compatibility, contact Nasuni Support.

Current compatibility of NMC with NEA (9.7+)

Volume Sharing Compatibility

When sharing volumes between Edge Appliances, both appliances must be running compatible versions.

Compatibility Rules

1. Volumes can only be shared within the same "compatibility group".

2. Version 9.15.3 is the bridge between the 9.x compatibility group and 10.x compatibility group.

3. If using Advanced Global File Locking (AGFL), all shared volumes must be on 10.0.2 or later.

Compatibility Groups

Group A (9.7.x – 9.15.x): These owning versions can share volumes with each other.

Group B (9.15.3 – 10.x): These owning versions can share volumes with each other.

*Must update from 10.0.2+ to share with 9.15.3 or 10.0.x.

Important: Versions 9.0.x – 9.5.x can only share volumes with each other, not with 9.7.x or later.

Legacy Volume Sharing (9.0.x – 9.5.x)

These versions cannot share volumes with 9.7.x or later.

Special Considerations

• AWS PrivateLink or FIPS endpoints: Volumes using these cloud credentials can only connect to Edge Appliances running 9.15.x or later.

• Advanced Global File Locking (AGFL): If enabled, all appliances sharing the volume must be running 10.0.2 or later.

Third-Party Compatibility

This section details Nasuni's compatibility with third-party infrastructure, including hypervisors, cloud storage, applications, and protocols.

Support Designations

Throughout this document, third-party products are classified into separate support levels:

Hypervisors

Nasuni Edge Appliances (NEAs), the Nasuni Management Console (NMC), and File IQ appliances deploy as virtual machines on your existing infrastructure.

Note: This table shows specifically tested configurations. Nasuni customers receive full contractual support for Nasuni software regardless of hypervisor. Any KVM-derived or Xen-derived hypervisor not listed is considered Compatible.

Cloud Platforms

Legacy Active Directory (End of Support)

Client Operating Systems

Currently Supported

End-of-Life Operating Systems

Windows DFS Support

Windows DFS Namespaces can organize SMB shares from multiple Edge Appliances under a single logical path.

NTFS Permissions

Traverse Permissions:

• NTFS Exclusive & Multiprotocol: Traverse not required from volume root; required from share root for browsing; direct subfolder access doesn't require traverse.

• NTFS Compatible: Traverse required at volume root and all intermediate levels; direct subfolder access requires traverse.

Note: You cannot switch from NTFS Exclusive mode to NTFS Compatible mode.
