ZFS-based QuTS hero operating system enhances NAS performance and data integrity
QuTS hero combines the app-based QTS with the 128-bit ZFS file system to provide flexible storage management, comprehensive data protection, and optimized performance to tackle the complexity and performance demands of modern IT. From storage management, virtualization, to collaborative media workflows, QuTS hero streamlines your business-critical tasks.
Tiered storage configuration for a QuTS hero NAS
Basic requirements for setup are similar to QTS. We recommend you to follow these steps to acquire optimal storage efficiency and performance for QuTS hero.
Step 1: System Drive & Default Shared Folders
Step 2: Read Cache & ZIL
Step 3: Data Storage
Inline data deduplication, compression, and compaction drives big data storage efficiency
QuTS hero supports advanced block-based data reduction technologies (including inline data deduplication, compression, and compaction) to reduce file sizes, conserve storage capacity, and optimize performance. For example, if 20 virtual machines on a NAS are replicated using the same template, then storage space requirements for all 20 virtual machines can be reduced by up to 95%. Whether acting as primary or backup storage, the TS-h686 optimizes storage utilization to provide a reliable storage cornerstone in the Big Data era.
Real-time SnapSync ensures minimal RPO with real-time disaster recovery
Real-time SnapSync ensures that both the primary and secondary NAS maintain identical data. When data is written to the source, it is immediately written to the destination. If the primary NAS goes offline, IT staff can simply adjust the privilege settings of the secondary NAS to ensure continuous operations. SnapSync provides the strongest support for nonstop business operations and helps users to reduce the risk of data loss.
Note: SnapSync will be available from QuTS hero h4.5.2.
The TS-h686 also supports snapshots and remote backup to help organizations accomplish routine backup tasks cost-effectively and efficiently.
