Data integrity is key - QuTS hero's self-healing ensures data integrity and reliability. Write Once, Read Many (WORM) is also supported. Data reduction improves storage efficiency and performance - Inline data deduplication, compression, and compaction reduce file size to conserve storage capacity and optimize performance. Multi-level cache technology - Main memory read cache (L1 ARC), SSD second-level read cache (L2 ARC), and ZFS Intent Log (ZIL) for synchronous transactions with power fail protection are simultaneously supported to boost performance and security. RAID Z enables robust data protection - Multiple RAID levels allow flexible capacity utilization. RAID Triple Parity and Triple Mirror deliver higher levels of data protection.
