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.

The 128-bit ZFS filesystem has huge capacity potential and supports native handling of standard RAID levels and additional ZFS RAID layouts (RAID Z). ZFS-based QNAP storage solutions provide up to 5 PB capacity for individual shared folders, enabling enterprises to tackle storage-demanding applications including Big Data analysis, edge computing, and AI. Designed to deal with petabytes of data, RAID Z quickly handles creating ready-to-use high-capacity RAID.

Inline data deduplication is block-based and runs before data is written to storage. This dramatically optimizes storage usage while significantly decreasing storage capacity requirements. Coupled with inline compression and inline compaction technologies, ZFS substantially reduces the overall storage footprint - beneficial for increasing SSD storage efficiency when highly repetitive data or massive small files are generated. All-flash solutions thus achieve higher cost efficiency while improving both random write performance and SSD lifespan.

QTS 5.0 builds upon its solid foundations with an updated system kernel and optimized user interface – followed by enhanced security measures to protect your digital assets, improved system performance to streamline your applications, and integrated AI machine learning to strengthen image recognition and drive failure prediction. Providing cutting-edge features to meet the challenge of rapid technological changes, QTS 5.0 brings you data security, power, and intelligence.

The new kernel improves PCIe performance, which enables QTS 5.0 to enhance NVMe SSD performance and utilization. When cache acceleration is activated, SSD storage can be utilized more efficiently while also offloading memory resources. It maintains high performance even when multiple concurrent users access the same shared folders, and transferring large-size files via SMB/NFS becomes faster.
