All-Flash Array Management System

The Web-based GUI for QSAN All-Flash Array

Reducing learning and maintenance efforts through our innovative interface design, we allow engineers to focus on more valuable efforts while reducing repetitive tasks and providing complete data analytics, XEVO caters to industry trends and changes observed through many user generations, as well as the demand for hardware and software, creating a new vision for this traditional industry.

Put in Your First Data in

Multiple Volume Create

Multiple Volume Create feature can save lots of time to do the repeatedly work to deploy huge amount of storage environment.


Analysis the Status of Business Usage

QReport as far back as 1 year eases the effort of IT managers by exporting a report to analyze the storage usage. At the same time, allows IT generalists to make a better resource arrangement faster than ever and easier.

Auto Replication

Intuitive UI Operations

Multiple backup solutions give you more choices to protect your data. By auto replication, you can easily deploy the remote replication without doing configurations. Through local-to-remote, you can transfer your local backup to remote sites without doing full copy. This technology gives you multiple ways to protect your digital assets safely.

Replication Easily Without Configurations

Login remote system through management port, and done.

Grouping Operation

Grouping What You Want

Grouping batch operation such as connect to server, modify, or backup. Grouping what you want, such as volumes, hosts, to decrease your loading of managing tones of different devices connections or backups. Grouping batch operation can help you save tones of time to manage your storage and prevent accidental damages caused by human negligence.
