EVO OS Version 3.0 Released

Recommended Posts

EVO OS Version 3.0 is now released.

If you purchased an EVO storage system after Oct. 31, 2011 you are eligible for a free upgrade to EVO OS v3. If you purchased prior to that date, please contact us for more information on upgrading your EVO.

What's New

EVO Version 3 is a major release, which includes many improvements to performance, setup, monitoring, security, and reliability. Some of the most notable additions and changes (including Beta/Preview functions) are summarized below.

Before upgrading the OS version on your Evo, it is imperative that you read the release notes and manual and plan for any changed functionality. Further, although an update to v.3.0 can be done with data in-place, a backup of all critical data should be completed and verified before beginning the update. You should also plan for a reboot, which will be required immediately after the upgrade process has finished.

The Evo 3.0 OS update can be applied to a version 2.1 or later Evo. If your Evo was shipped prior to the release of v.2.1, performance will be significantly improved from just the software update, though your Evo may not be as powerful as an Evo that shipped with 3.0, because Evo's hardware is continually improved.

As a result of substantial changes to the handling of SAN+NAS volumes in version 3.0, you will need to recreate the NAS mapping of any existing SAN+NAS volumes after updating from 2.x to 3.x or higher. In some cases, such as SAN+NAS NTFS volumes and SAN+NAS volumes greater than 2TB, it may not be possible to restore the NAS mapping. These changes were necessary to improve stability and reliability of the SAN+NAS function.

In addition to these notes, there are a myriad of new features and options, which are documented in the relevant sections of the user manual.

  • AFP (Apple Filing Protocol) access to NAS volumes
