First Time SETUP Guide for QNAP QuTS Hero h4.5.3 NAS - Complete Walk Through

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. Inline Data Deduplication Inline deduplication is block-based and is carried out before data is written to storage. This greatly optimizes storage usage while significantly decreasing storage capacity requirements. Inline Compression Compress data to reduce storage I/O workloads for improved performance. In VDI, deduplicated virtual desktops are easily cached to achieve optimal virtual desktop performance. Inline Compaction Especially helpful for increasing SSD storage efficiency when highly repetitive data or massive small files (e.g. transaction logs of banks or e-commerce) are generated. It delivers higher cost efficiency for all-flash storage systems. Self-Healing ensures data integrity and reliability Data integrity is key to the reliability of applications and databases. As SSD adoption grows, businesses will encounter a greater risk of data loss as it is difficult to recover data from a dead SSD. Designed with a focus on data integrity, ZFS uses end-to-end checksums to detect and correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors. If an integrity violation is detected, ZFS automatically repairs the damage using data from another mirror before the data is passed to applications. QuTS hero is also WORM (Write Once, Read Many Times) compliant to ensure that data, once written, cannot be modified. Robust data protection and flexible capacity utilization with RAID Z QuTS hero supports conventional RAID configurations (RAID 0 (Striped), RAID 1 (Mirror), RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60) and adds support of RAID Triple Parity for protecting against three-disk failures and Triple Mirror for an identical copy of data stored on three disks. Designed to deal with petabytes of data, RAID Z demonstrates an outstanding tool for creating ready-to-use high-capacity RAID in a matter of seconds. Multi-level cache technology with both read and write boosts performance ZFS simultaneously supports the main memory read cache (L1 ARC), SSD second-level read cache (L2 ARC), and ZFS Intent Log (ZIL) for synchronous transactions. The L1 ARC works with the L2 ARC to minimize hard drive access requirements while boosting read performance. The ZIL is useful for applications with large synchronous random write workloads (such as databases), as data will be written to the ZIL first and then written to storage, helping to decrease latency and improve write performance. Near-limitless, instant snapshots bring you peace of mind Supports up to 65,535 snapshots for iSCSI LUN and shared folders (if 1 snapshot is created every hour, 24 snapshots per day, then up to 7 years of snapshots can be created without needing to delete any!). Copy-on-write technology makes snapshot creation almost instantaneous without affecting ongoing data writing. Pool over-provisioning ensures write performance With Pool Over-provisioning, space can be flexibly reserved in a storage pool to allow new data to be written into a complete block even if the pool is almost full, thus improving the performance of fragmented pools. For write-intensive workloads and performance-demanding applications (such as SQL transaction logs, backups, surveillance, and medical videos) you can set a higher pool over-provisioning to attain higher write performance.
