QuTS hero is the operating system for high-end and enterprise QNAP NAS models. With Linux and ZFS, QuTS hero supports advanced data reduction technologies for further driving down costs and increasing reliability of SSD (all-flash) storage.
ZFS-based QuTS hero ensures performance and data integrity
Faced with the explosive growth of data, VDI popularity, increasing SSD adoption, 8K media, and other disruptive IT trends, modern businesses need dependable storage systems to meet future demands. QNAP’s new “QuTS hero” operating system combines the app-based QTS with a 128-bit ZFS file system to provide flexible storage management, comprehensive data protection and optimized performance to meet the needs of business-critical applications.
About NAS migration and RAID management for QuTS hero
As ZFS metadata management is different from Ext4, QTS-based NAS drives cannot be directly used by a QuTS hero-based NAS (and vice versa). Users can install new hard drives to start QuTS hero. If QTS users want to use their existing drives in QuTS hero, they must first ensure all of their drive data has been backed up, and then initialize the hard drives. It is recommended that users thoroughly evaluate their storage needs before installing QuTS hero.
Expanding the storage capacity of a QuTS hero NAS requires adding a complete RAID group to the Storage Pool. Once a RAID group is created, it does not support expanding a RAID group by adding an individual hard drive and does not support migrating RAID levels. Users can allocate spare hard drives for Hot Spare protection or creating additional RAID groups. Users must have enough drive bays to facilitate storage expansion needs in the future when configuring storage in different stages.
