Latest DXi Software:

  

DXi 5.3.1
Release Date:  

April 2026
New Features:  

This software release features the following new features and updates:

  • Increased replication throughput (DXi9100, DXi9200)- Default replication stream counts and OST worker thread limits have been tuned upward for DXi9100 and DXi9200 platforms. This improves OST optimized duplication and AIR replication performance under high-concurrency workloads.

  • Improved QXS storage array monitoring and resilience (DXi9200)- DXi now detects and reports QXS controller unresponsive states that were previously silent. When a QXS management controller becomes unavailable, the system generates a RAS alert and correctly reflects degraded status in the GUI rather than showing normal operation.

  • QXS drive replacement workflow (DXi9200)- A new upgrade script automates the QXS drive replacement procedure, including incorporating available drives into RAID sets, global spare configuration, and automatic rebuild initiation.

Software upgrade requirements from earlier versions are available in those earlier-releases' Release Notes and archived in your product's documentation center at Resources > Release Notes > Release Notes Archive.

Note: Quantum strongly recommends upgrading to the latest version of DXi software before installing capacity upgrades, regardless of the capacity increment.
